Green Utopia - made in Green Tech Valley
Utopias are characterized by the unrealizable, the fantastic. But this is precisely where their massive power lies; these images of the future are what make revolutionary developments possible in the first place. “And the climate crisis, as well as the associated shift toward a comprehensive resource and circular economy, require almost utopian thinking in the same way,” Bernhard Puttinger, Managing Director of the Green Tech Valley, is convinced. “We have to be faster than climate change. That is the order of the day. This is where visions, this is where courage, this is where green solutions are needed.” And Green Tech Valley, as an international hotspot for green research & innovation, has a special significance in this regard, emphasizes Puttinger.
Cooperation for a green future
For this reason, forces were joined together with the Graz University of Technology, the Montanuniversity of Leoben, the Institute for Design and Communication of the Joanneum University of Applied Sciences, Creative Industries Styria and Holzcluster Steiermark. Interdisciplinary student teams produced green utopias here as short videos as part of Designmonat Graz – visualizing a possible future of the energy, mobility and raw materials turnaround based on current research at the site. “Utopias grow into technologies here,” says Stefan Vorbach of Graz University of Technology enthusiastically of the results, which were presented. Illona Otto Wegener Center for Climate & Global Change (University Graz) points out to consider all social structures: “Green Utopia helps us to visualize and discuss the future ahead of us. If we know what the goal is, we can reach it faster.”
Visions spur innovation
The videos range from new post-consumer lifestyles and climate-positive construction to trees as electricity storage for stable grids. Utopian? From today’s perspective, quite so in some areas. “This in particular is an incentive for research and for companies in Green Tech Valley,” says Puttinger. Stefan Spirk (Graz University of Technology) also emphasizes this: “It is of immanent importance to imagine the unthinkable in order to be able to realize revolutionary technologies.” Sarah Meitz from AAE Intec – Institute for Sustainable Technologies also speaks of the courage to take new, radical paths, for example “in the production of hydrogen from wastewater and sunlight in solar reactors”: “Green utopias are needed to ensure climate-friendly and cost-effective energy supplies.”
We dream it, so we can do it! - AGAIN
Green Utopia - made in Green Tech Valley 2025
“Green Utopia – made in Green Tech Valley” once again highlights the future based on visionary Austrian research. The award ceremony for this year’s researchers and Vizualize teams took place on May 27 as part of Design Month at the Hornig Areal.
From smart “soil sensors” to CO2 stored in building materials…
Dominik Steinberger from TU Gaz is the “utopist” behind the term “biochar,” or plant carbon. Carbon from biomass is proving to be a promising economic sector for the future and is increasingly becoming the focus of industry, as biochar can be used for much more than just soil improvement or as an additive in building materials. Steinberger’s vision for 2050: “Biochar will be used specifically to bind carbon, close material cycles, and conserve resources. Cities will become carbon sinks themselves: instead of climate-damaging building materials, buildings will be made of highly porous biochar components that regulate moisture, store heat, and bind CO₂ in the long term.”
Morten Streblow, also at Graz University of Technology, is committed to the EU project SPIN-FERT. The aim is to process various agricultural by-products and waste products to produce high-performance fertilizers and growth substrates without peat. In the Utopia short video “Soil-Nose,” the “soil nose” is the program. In reality, there is a lot of AI behind it.
Viktoria Schett is researching efficient and easily accessible goods transport in car-free urban areas at the University of Graz. Her research focuses on the CarryMeHome concept: “This represents a visionary solution for mobility and transport in car-free (inner) cities of the future. The focus is on (semi-)autonomous trolleys that serve as flexible and sustainable transport aids.”
… to green hydrogen valleys and wood building materials that last forever.
According to Ernst Alexander Dengg from Graz University of Technology, the paradigm shift in the construction industry over the next few years must be from reuse to ever-use: What is needed is integrity-oriented planning that focuses on the wooden component itself and not just the entire building as a “community of fate”: “Because while structurally used solid wood remains functional for several hundred years with good care, buildings are often renovated or demolished after only 20 to 50 years.”
“In Styria, the amount of residual waste per capita is over 100 kg per year, but only about a third of this actually belongs in the residual waste bin. The majority of the waste consists of materials that should be collected in a different bin,“ explains Paul Demschar from Montanuni Leoben. His question for ”Magic Bin” is: What role can AI-supported systems, digital sorting aids, or smart waste bins play in minimizing incorrect disposal?
Styria, together with Carinthia and Upper Austria, caused an international stir last fall with the first European Hydrogen Valley for industrial applications. This is where Michael Richter from Graz University of Technology/HyCentA comes in with his vision of “A New H”: “By establishing regional ecosystems, resilient production and consumption structures, introducing standards, and creating supraregional links to large-scale hydrogen unions, the path to FREE H is being paved.”
But what lies behind these creative titles, and how far apart are research vision and reality? Have a closer look!

Biochar 2050: From utilization to regeneration – The biochar world of tomorrow
The world of 2050 is characterized by a paradigm shift in materials management. Biochar, once a by-product, has become a key resource in the renewable circular economy. It is not just a material, but an essential element for restoring natural cycles.
Material-centered approach: Biochar as a source of added value: Biochar is no longer viewed solely as a soil conditioner or building material additive—it is a product that retains its value over time and has a wide range of functions. Whether in soils, building materials, or industrial processes, biochar is used specifically to sequester carbon, close material cycles, and conserve resources.
Cities for carbon reduce: Instead of climate-damaging building materials, buildings today are made of highly porous biochar building elements that regulate moisture, store heat, and bind CO₂ in the long term. Cities are no longer sources of emissions, but active carbon sinks that have a positive climate effect thanks to biochar building materials.
Soils as storage and filters: Biochar is the backbone of regenerative agriculture. Soils worldwide are enriched with biochar, which helps them retain nutrients, store water, and stabilize agricultural yields. This targeted use has doubled humus content and made global food production more resilient to climate change..
Innovative approaches
- Carbon Retention-Driven Design: Every product containing biochar is developed with the goal of long-term carbon sequestration. Instead of short-lived applications, the focus is on longevity and recyclability.
- Negative Emission Economy: Companies and cities no longer just account for emissions, but also for the amount of carbon that is actively removed and stored by biochar. Biochar has become the central currency of carbon markets.
- Maximizing biochar value creation: Biomass residues are converted into valuable biochar worldwide by decentralized pyrolysis plants. The cascade of uses is optimized: From industrial applications to the construction industry to soil improvement, biochar goes through various life cycles before being stored in soils for the long term.
Ecological and economic advantages
- CO₂ storage instead of emissions: Biochar in building materials and soils stores billions of tons of carbon.
- Stable value thanks to material passports: Every biochar product is traceable and integrated into digital carbon balances.
The world of 2050 has changed—not only in terms of technology, but also in terms of values. Carbon is no longer seen as a threat, but as a resource that can be shaped.
Biochar is the symbol of a new ecological age in which the economy, the environment, and society are in harmony.

CarryMeHome – Transportation of goods in the future
By 2040, many cities and urban centers around the world will be car-free in order to cope with increasing urbanization, climate protection requirements, and citizens’ quality of life. Nevertheless, the need for efficient goods transport remains, whether for retail, private moves, or everyday shopping.
The CarryMeHome concept represents a visionary solution for mobility and transport in car-free (inner) cities of the future. The focus is on (semi-)autonomous trolleys that serve as flexible and sustainable transport aids. They can follow people who are traveling by active means of transport such as bicycle or on foot, but also in wheelchairs, and transport their goods. In addition, they are able to operate completely autonomously, for example by returning independently to the nearest sharing station.
Why (semi-)autonomous trolleys are needed:
- Car-free (inner) cities and efficient goods transport: (Inner) cities are becoming increasingly car-free. At the same time, the need for efficient goods transport remains.
Promoting health: The trolleys promote a healthy lifestyle by enabling users to be physically active while transporting goods. - Inclusion and sharing: The trolleys are designed as part of a sharing system, making them accessible to everyone.
Promoting seamless mobility: The sharing stations can be integrated into mobility hubs that link different modes of transport such as bicycles, e-scooters, and public transport to promote efficient, seamless, and flexible urban mobility. - Support for people with limited mobility: The trolleys can actively support older people who cannot carry heavy loads or people with physical impairments, such as wheelchair users, by transporting their loads.
By 2040, CarryMeHome could play a central role in reshaping urban mobility. City centers will not only become car-free, but also more socially inclusive and sustainable. The (semi-)autonomous trolleys are not just a technological aid, but a symbol of people-centered and environmentally friendly urban transport. They make everyday life easier for citizens while helping to minimize resource consumption and redefine public space. CarryMeHome can help create a future in which the transport of goods and the support of people are harmoniously combined with the vision of sustainable, smart, and livable cities.

High-performance peat-free fertilizers and growth substrates made from agricultural by-products and waste products
Our vision is to develop alternative substrates that work at least as well (ideally better) than peat-based substrates without having a harmful impact on the environment. As microbiologists at UBT, we are particularly interested in the plant-promoting properties of various microorganisms and how we can incorporate them into the substrate. The aim here is to enable these plants (e.g., tomatoes, lettuce, or blueberries) to grow faster in horticulture, be more resistant to various pathogens, and deliver better yields with better nutritional values. These parameters are known to be significantly influenced by the plant microbiome, and we want to specifically promote, control, and observe this. To this end, various tools are to be developed that enable quick and easy monitoring, including a cost-effective electronic nose that enables soil health diagnosis based solely on the scent signature.
Soil microorganisms synthesize various volatile organic compounds (VOCs). These should be identified and assigned to specific harmful or beneficial microorganisms in order to quickly and easily assess the health of the soil. The early detection of pests and the targeted enrichment of beneficial organisms can thus be carried out on site without great effort and, in the future, even by AI-supported robots. Environmental and climate protection aspects are particularly relevant here. The e-nose can certainly be presented well, showing the “bad” smells of diseased soils and plants, the intervention of farmers and scientists, and the “better” scent under healthy conditions, which is reflected in better products.

Integrity of solid wood components: A paradigm shift from reuse to ever-use
Wood construction in 2040 will be characterized by a paradigm shift toward a comprehensive circular economy. The “ever-use” strategy for solid wood components sets new standards in sustainability and resource efficiency.
Component-centered approach: The key is to view components as products rather than buildings as a whole. The focus is on the component. Each element is treated as an integral, value-preserving product with long-term added value that fulfills its function over several building cycles. Geometrically intact components are treated as resources with long-term stable value.
Buildings as temporary material banks: Planning focuses on the reusability and value retention of wooden components over several building cycles. This results in an integrity-oriented construction method. Integrated material passports document the properties and enable the reuse of components. These are dismantled without damage and retain their value—the basis of an integrity-oriented construction method.
Innovative approaches
• Comparison of IOK and RK The integrity-oriented concept (IOK) shows that 90% of the wood mass remains intact. This reduces the amount of primary wood required and maximizes recyclability. Conventional timber construction (RK) does not achieve this level of efficiency.
• Material retention-driven design The geometry and mass of the components are protected to enable versatile reuse. This is achieved through detachable connection techniques and the use of a new tectonic design.
• Maximization of wood utilization: Local solid wood products with reduced wood losses (55% wood yield for solid wood compared to 36% for glulam/cross-laminated timber) are used, which maximizes resource yield. This allows wood to be used more efficiently than in industrial glued wood products.
Ecological and economic advantages
• CO₂ reduction through lower primary wood consumption and shorter transport routes.
• Value and resource stability through long-term preservation and reuse.
• Maximized efficiency: Wood remains in circulation longer and is only used in a cascading manner at the end of its life.
This integrity-oriented construction method fundamentally transforms timber construction. Buildings are no longer viewed as static units, but rather as dynamic resource stores—and that is a key step toward a truly circular economy.

Utopia 05 – Magic Bin

where you can recycle even residual waste”

Non-recyclable waste bin in urban areas
In Styria, the amount of residual waste per capita is over 100 kg per year, but only about one-third of this actually belongs in the residual waste bin. The majority of the waste disposed of in the residual waste bin is misplaced waste—i.e., materials that should actually be collected in a different bin. In addition to organic waste, this particularly affects packaging made of plastic, metal, paper, or glass.
In Austria, the contents of residual waste bins are mostly incinerated, which means that valuable resources are lost to the recycling cycle. While biogenic waste can be processed into high-quality compost in composting plants, plastic and metal packaging can be recycled and reused. However, even the best and most innovative recycling processes are ineffective if waste is disposed of incorrectly and therefore never enters the intended recycling process.
The European Union has set itself the goal of halving the amount of residual waste by 2030 in order to promote the circular economy and conserve resources. However, current data shows that waste volumes are continuing to rise, especially in urban areas. This makes it clear that existing measures are not sufficient and that new, visionary solutions are needed.
Analyses of residual waste composition show that both the amount of residual waste produced per capita and the number of items incorrectly disposed of in residual waste bins are particularly high in densely populated urban areas. This leads to the conclusion that the more people live in a confined space, the worse their waste separation habits become. The reasons for this are anonymity, lack of knowledge, lack of incentives, and insufficient awareness of proper waste separation.
The trend toward increasing urbanization thus contradicts efforts to establish a functioning circular economy. In order to enable closed material cycles, it is essential to drastically reduce the amount of recyclable materials in residual waste bins. However, traditional waste management is reaching its limits with its current methods—a purely technical solution does not seem to be sufficient.
Visionary approaches to solutions:
This is where the Green Utopia Project 2025 comes in: the vision of a residual waste bin free of recyclable materials should not only be defined as an abstract goal, but also underpinned by concrete research approaches and innovative solutions. In particular, the following questions should be taken into account:
• Technological innovations: What role can AI-supported systems, digital sorting aids, or smart waste bins play in minimizing incorrect disposal?
• Social and psychological approaches: How can awareness of waste separation in urban areas be sustainably increased? What incentive systems could be effective?
•Regulatory and infrastructural measures: What political and urban planning measures could bring about a reversal of this trend?
The project serves as a platform for identifying and discussing visionary solutions—from technical developments and behavioral psychology measures to experimental waste management strategies.

FREE H – Fully REnewable EcosHystem
Instead of a fossil-based energy supply with high geopolitical dependencies, increasing supply uncertainties, and increasingly precarious climatic conditions for humans, a fully renewable hydrogen ecosystem offers all the technological solutions needed to make the best possible and sustainable use of renewable energy sources at different locations.
Huge photocatalytic hydrogen production plants (photoelectrolysis) in the sunniest spots on Earth, floating electrolysis plants linked to offshore wind turbines, the use of naturally occurring hydrogen, standardized modular systems for private households, decentralized systems directly at the consumers’ premises, and generally technologically mature production plants offer a diversified range of options for producing hydrogen on a large scale in a cost-efficient manner.
Electrochemical compressors (EHC) ensure the efficient operation of transcontinental pipeline networks for the distribution of hydrogen, process-related CO2, and mixed gases from natural gas, biomethane, and hydrogen. The purification capabilities of EHC technology make it possible to supply high-purity hydrogen to refueling stations served by pipelines, largely replacing costly trailer-based supply solutions.
In the industrial sector, processes that cannot be electrified are powered by hydrogen or biomethane, and the additional use of oxygen from electrolysis (oxyfuel) leads to increased efficiency in combustion processes and sewage treatment plants. A comprehensive network of filling stations across Europe enables public transport in topologically and climatologically challenging environments, heavy goods transport, and also shipping and aviation based on hydrogen and its derivatives, produced using the collected CO2.
The gradual development of regional ecosystems (hydrogen valleys), resilient production and consumption structures, the introduction of standards, and supraregional links to large-scale hydrogen unions are paving the way toward FREE H.

Statements by university rectors and managing directors on Green Utopia 2025
Utopias are often the starting point for research questions because they paint visionary pictures of a sustainable future and can trigger targeted developments for a greener world. Graz University of Technology is dedicated to researching sustainable systems as a central component of its research profile. In the field of expertise “Sustainable Systems,” we work across disciplines on topics such as green mobility, sustainable energy systems, and innovative building technologies. Graz and Styria are a real hotspot for innovation: here, some of the brightest minds are working together to develop forward-looking solutions to the major challenges of our time, inspired by encouraging green utopias.
The major societal challenges in the areas of resource scarcity, climate change, energy supply, and environmental protection require innovative approaches based primarily on technical and scientific methods. The Montanuniversität Leoben has set itself the task of making decisive contributions to overcoming these challenges through excellent research and high-quality education. A prime example of these efforts is the new Hydrogen Center, which opened in the fall. This state-of-the-art center will be dedicated to the research and development of green hydrogen, a key technology for the energy transition and a sustainable future. The Montanuniversität Leoben is characterized by its strong networking and interdisciplinary cooperation. The “Green Utopia” project will further strengthen the location by creating synergies and promoting cooperation between various actors. This project not only provides space for visionary ideas and bold solutions, but also supports the development of sustainable technologies that make a positive contribution to society.
As a forward-looking university, we firmly believe that only those who dare to imagine new worlds can shape our tomorrow. That is why we encourage teachers, students, and staff to think outside the box when it comes to topics such as digitalization, climate change, and mobility—and to actively explore the future. Our institutes make the future tangible: whether it's sustainable food management at the Institute of Applied Production Sciences, electromobility at the Institute of Automotive Engineering, or new working environments at the Institute of Industrial Management, we bring theory and practice together. Our design students also shape visions of the future: with the visual implementation of Green Utopia, they show how sustainable visions can take shape."
Green Utopia is more than just an event during Design Month. It sends a strong signal about how important it is to embed sustainable thinking in creative education and beyond the research community. Especially now, when climate change and social responsibility are moving down the agenda, formats like this are more urgent than ever to encourage young people to develop new perspectives, actively work on solutions, and stick with them. We at the University of Graz support this and are happy to get involved proactively.

Multiple cascading uses of wood
Lightness, flexibility & sustainability
The idea of multiple cascading uses of wood is transforming industries and creating a future where environmental sustainability takes center stage. The innovative use of wood in technology products reduces fossil fuel consumption, maximizes CO2 sequestration and takes an important step towards a greener and more sustainable world. In this utopia, wood is no longer just a building material, but a symbol for the intelligent use of resources and for innovations that respect and protect our environment. für Umweltsystemwissenschaften, Uni Graz

“IMAGINE: Nature as a legal person

Video-Team Institut für Design & Kommunikation – FH Joanneum: Alice D’Aiuto, Antonia Sophia Marie Muszi, Hanna Weichsler, Laura Galvanetto & Lisa-Marie König
Nature receives personal rights
In the future, an alternative economic model will emerge that is based on a revolutionary concept concept: nature is granted legal personal rights that guarantee it the right to exist, thrive and regenerate. Inspired by existing approaches in Latin America, this model goes far beyond this and places the relationship between the economy, society and the environment on a completely new basis.
In this utopian scenario, nature is no longer seen as a mere resource to be utilized and exploited, but rather to be used and exploited, but as an essential partner with its own rights. Companies and private individuals have a legal obligation to consider the impact of their actions on the and ensure that their activities do not violate the rights of nature. This is leading to a profound change in the way economic decisions are made and is forcing decisions are made and forces all players to place sustainability and environmental protection at the environmental protection at the heart of their strategies.
Participation of civil society
Another key element of this model is the active participation of civil society and indigenous communities in indigenous communities in decisions that affect the environment. The involvement of these groups in the decision-making process ensures that a variety of perspectives are taken into perspectives are taken into account and the deep connections between people and their natural are recognized. This promotes a culture of coexistence and respect for nature that goes far beyond the boundaries of traditional economic models.
In this utopia, recognizing the rights of nature leads to a world where economic progress and environmental protection go hand in hand. Companies flourish because of their innovative and sustainable approaches, while at the same time natural ecosystems are protected and regenerated. Society is developing a new awareness of the importance of nature, which is reflected in a respectful and responsible approach to the environment.
This alternative economic model shows a way for humanity to live in harmony with nature and create a sustainable future for all living beings on our planet.

Biogenic waste without plastic as a contaminant
In the future, we will experience a revolution in composting – the era of “plastic-free compost”. This ambitious project aims to improve the quality and quantity of compost through a cycle-oriented approach to the individual processes – from collection to pre-processing and to post-processing – to significantly improve the quality and quantity of compost. The central challenge is to to make the removal of the contaminant plastic more efficient in order to minimize the environmental impact and increase the quality of the compost.
Biogenic waste, the basis for high-quality compost, is an essential component of a functioning circular economy. However, the increasing problem of plastics, especially microplastics, poses a growing challenge for the organic cycle. Plastics in compost not only jeopardize soil quality, but also enter our food chain.
Innovative cycle-oriented processes
In this utopia, the amount of plastic in biogenic waste is reduced through innovative, cycle-oriented processes. This includes better pre-treatment for more effective separation of plastics and improved post-treatment methods to further optimize the separation. Traditional shredders and screens in pre-treatment are complemented by advanced technologies and advanced screening and air separation methods are used in post-treatment. A particular focus is on the research and development of sensor-based sorting techniques that enable more precise separation of plastics. This project goes beyond traditional composting and integrates scientific findings in order to optimize the understanding and improving the transformation of plastics during composting.

Video-Team Institut für Design & Kommunikation – FH Joanneum: Helene Gödl, Katharina Mundigler, Maike Klemm & Tina Zopf
The reinvention of peri-urban spaces as sponge areas
The year 2050 marks an era in which cities and urban areas have become resilient oases in the face of climate change. Thanks to the pioneering research project PeriSponge, peri-urban mobility spaces have been transformed into life-giving sponge areas. Previously threatened by floods, droughts and biodiversity loss, these areas are now characterized by a now revitalized by a blue-green transformation. The once clear boundaries between city and nature are blurring in a harmonious interplay of resilience and regeneration.
In this new world, public spaces, designed according to the principle of blue-green transformation, have become vital components of urban landscapes. They not only offer protection from extreme weather events, but also promote urban biodiversity and create cool, shady shady havens in the midst of urban heat islands. Streets and squares, once gray and sealed, are now living, green arteries that absorb rainwater, provide habitats and improve the microclimate.
Efficiency and quality of life in sponge cities
Advanced technologies and sustainable design are seamlessly intertwined in this future to maximize maximize efficiency and quality of life in these sponge cities. Smart water management systems, controlled by artificial intelligence, regulate water flow and storage to prevent flooding and survive periods of drought.
Photocatalytic surfaces and integrated solar technology help to purify water and air while at the same time generating energy for public facilities. The 2050 vision shows peri-urban areas as vibrant, green networks that interweave cities and landscapes. Sponge areas that store rainwater and and prevent flooding have become the norm. These green corridors not only serve ecological balance, but also as invigorating, communal spaces that invite people to linger and increase the well-being of city dwellers.
People and nature in harmony
In this utopian future, every initiative, every project is a step towards a world in which sustainable coexistence is a reality. PeriSponge is an example of this transformation, a symbol of a future in which humans and nature live together in perfect harmony.

“IMAGINE: Cyanobacteria work for industry
… Enabled by replacing chemicals with organic processes for a greener planet”Green Utopist: Peter Erlsbacher, TU Graz
Video-Team Institut für Design & Kommunikation – FH Joanneum: Anna-Katharina Hammerer, Sofia Neudecker & Tea Mauko
Cyanobacteria as green catalysts
In the future, we will have achieved a groundbreaking turnaround in the chemical industry. The heart of this revolution are cyanobacteria, which act as green catalysts and offer an environmentally friendly alternative to traditional chemical processes. Cyanobacteria are able to produce enzymes that are needed to carry out
electron transfers (redox reactions). This makes it possible to carry out complex redox processes efficiently and in an environmentally friendly manner without the need for expensive and environmentally harmful catalysts or energy-intensive conditions.
Of particular note is the production of NADPH, a molecule that is widely distributed in nature and can power many different redox reactions. Research has found a way to effectively recycle this expensive molecule by using cyanobacteria, which are able to recycle NADPH directly from water using light energy, resulting in oxygen as the only waste product.
Integration into industrial processes
In our utopia, these genetically optimized cyanobacteria are used on a large scale to catalyze a variety of chemical reactions in a way that is both economically and ecologically sustainable. They enable the production of pharmaceuticals, plastics and many other important chemicals without the environmentally damaging side effects associated with traditional methods.
Another key advantage of this technology is its ability to be stereoselective, which means that they can specifically produce one of the two mirror images of a molecule. This
This precision is particularly invaluable in the pharmaceutical industry, where the wrong isomer of a drug can have harmful effects. The ability to specifically produce the desired form of a molecule is revolutionizing drug manufacturing, facilitating the safe and effective production of new therapies. The integration of cyanobacteria into industrial processes has not only transformed chemical production, but has also established a new sector of green technologies based on the coexistence of industrial development and environmental protection. Industrial plants that were once among the biggest polluters are now pioneers in the use of renewable energy and the minimization of greenhouse gas emissions.
This is a shining example of how innovative research and respectful treatment of nature can pave the way to a future worth living for all living beings on our planet.

“IMAGINE: Plants as blood vessels
… Enabled by revolutionary & patient-specific 3D-prints from organic materials for more health“
Green Utopist: Florian Lackner, TU Graz
Video-Team Institut für Design & Kommunikation – FH Joanneum: Larissa Holweg, Lea Haas, Ramona Groß, Sophie Lautischer & Stefanie Weber
Inspired by the fundamental insight that nature is an irreplaceable partner in the development of sustainable technologies, researchers have developed a groundbreaking method to revolutionize healthcare in this utopia: the creation of plant blood vessels in the laboratory.
Our society, which is increasingly characterized by demographic change, is facing a growing demand for implants and organs that cannot be adequately met by conventional methods – using fossil, unsustainable materials or ethically questionable allo- and xenotransplants.
Inspired by this urgent need, researchers have developed a pioneering solution: the creation of exact, personalized replicas of blood vessels through the 3D printing of plant-based biopolymers. These biopolymers, derived from an innovative blend of alginate from brown algae and nanofibrillated cellulose from wood fibers, offer greater biocompatibility due to their natural origin, allow for patient customization and promote sustainability while reducing reliance on animal testing and xenotransplantation.
These artificial blood vessels are produced in specially developed 3D printers equipped with a rotating fourth axis. This innovation makes it possible to create tubular structures whose cellulose fibers can be aligned to mimic the complex fiber structure and anisotropic mechanical properties of natural tissues – such as those of a human aorta. This process is not only a demonstration of technical finesse, but also a testament to the ability to mimic and augment nature.
In this visionary future, 3D-printed, patient-specific blood vessels grown in the laboratory will offer a safe and sustainable alternative to conventional transplants. They eliminate the need for donor organs and the ethical dilemmas associated with animal testing, opening the door to a new era of medicine. An era in which technological progress and ecological responsibility go hand in hand..

“IMAGINE: CarbonBusters turn toxic into good
… Enabled by depolarized electrolysis – from flue gas to products & green hydrogen“
Green Utopist: Lukas Rössler, TU Graz
Video-Team Institut für Design & Kommunikation – FH Joanneum: Alexandra Suváková & Mariam Gvivradze
Depolarized electrolyzers
In this vision, the question is why be carbon-neutral when you can be carbon-negative with green hydrogen. The most common method for producing green hydrogen is water electrolysis, which is already widely known but energy-intensive.
In the SHyRE project, researchers at TU Graz are working on innovative, depolarized electrolysers. To make them work, a toxic gas from the atmosphere or from industrial gas waste is used to depolarize the electrolysis cell. In this way, the same purity of hydrogen is produced with less energy consumption. A highly valuable by-product (instead of O2 in conventional electrolysis) is produced in large quantities. By removing impurities from the atmosphere or process streams, depolarized electrolysis actively reduces the amount of greenhouse gases emitted and converts them into a valuable compound. And all this while producing high-purity H2 at the same time.
This technology looks like a competitor to the traditional water electrolyzer, but in reality should be a coexisting alternative for a variety of industries that need to clean up their emissions: Mining plants, biorefineries, pharmaceutical and plastics industries.

RailCharge
In a world where the challenges of electromobility are becoming urgent, the RailCharge utopia represents a visionary solution. Electric vehicles face the problem of limited ranges and long charging times, which, together with increasing traffic congestion and the need for sustainable resources for batteries, is an urgent problem. Electricity grids are also reaching their limits with fast charging at peak times.
RailCharge addresses this problem with the following idea: instead of equipping electric cars with ever larger batteries and promoting individual transport, electric cars are loaded onto trains using innovative, efficient loading systems and automatically charged during the journey using Matrix Charging®. This concept not only provides a solution to the existing limitations of electric vehicles, but also promotes emission-free mobility and reduces traffic load.
Electric vehicles are parked on train carriages at railway stations, with an innovative transfer system significantly minimising waiting and loading times for passengers. Flexible loading and unloading at intermediate stations is also important for success and comfort. This can be achieved by adapting existing wagon systems or by developing new wagon designs.
Matrix Charging® technology is used at each car parking space in the train carriage. This automated connection technology with the charging pad on the floor of each car parking space enables an efficient and flexible charging infrastructure.
An interface to the train’s energy management system ensures efficient energy distribution and grid-friendly charging. At the destination station, the vehicle is fully charged and picked up by the passengers ready to continue their journey. In the meantime, they spend a pleasant stay in train compartments.
An evaluation of customer acceptance and environmental impact has already been carried out in the project and has shown a high potential for realising this utopia.
RailCharge offers a new perspective on long-distance transport with electric vehicles by enabling the seamless integration of road and rail transport. RailCharge opens a new chapter in the history of mobility – a step towards a more efficient, sustainable and connected future: The motorway by rail

Statements
‘Sustainable Systems' is TU Graz's greatest area of scientific strength. Here, researchers from all disciplines and faculties work together on complex challenges and research sustainable solutions. The spectrum of research topics ranges from future-orientated urban planning, innovative building technologies and the use of renewable energy sources to intelligent energy networks and green mobility. In disciplines such as railway research, hydrogen research or sustainable energy systems, TU Graz is one of the international research leaders. A location becomes a centre of innovation when it thinks and researches across disciplines, institutions and borders and works on solutions for major social challenges. Styria is such a place, where bright minds are uninhibited and inspired to research encouraging utopias. And initiatives like Green Utopia give them the stage."
The major challenges facing society in the areas of resource scarcity, climate, energy and the environment predominantly require the use of technical and scientific methods. The University of Leoben sees its task as making a significant contribution to overcoming these challenges through excellent research and high-quality education. One current project involves the construction of the new hydrogen centre, which will open in autumn. In future, this centre will conduct research at the highest level into the production of green hydrogen. Or in the field of recycling, where basic principles such as digital, sensor-based waste analysis and sorting technologies are being researched at a research facility. The University of Leoben has always been characterised by its networking and interdisciplinary cooperation. The Green Utopia project will further strengthen the location while benefiting the individual stakeholders. This project also offers space for visionary ideas and bold solutions."
As a university of the future, FH JOANNEUM is convinced that green utopias are needed to make the future of our society worth living in. We encourage people to think ahead and conduct research into important topics such as digitalisation, health, climate change, energy and mobility. Students and lecturers at all our institutes are therefore already tackling future topics in a practical way: the Energy Lab and Mobility Lab at FH JOANNEUM in Kapfenberg are researching renewable energies and forms of mobility, among other things. Environmentally friendly aviation is the focus of the Aviation degree programme in Graz, sustainable tourism at the Institute of Health and Tourism Management at FH JOANNEUM in Bad Gleichenberg. And last but not least, our Information Design students deal with green utopias when they visualise the contents of the eight green research utopias of 'Green Utopia' in order to communicate them to the public."
At the University of Graz, we provide answers to the questions of our time. For these major challenges, including digital change, social upheaval and the climate crisis, the University of Graz provides solutions and explanations that we bring to the people. For example, our researchers have achieved a breakthrough that could become a game changer for the plastics industry. Chemists have developed a fully recyclable, bio-based epoxy plastic. An innovation with major implications that combines environmental protection and economic efficiency. Scientists at the University of Graz are used to pushing the boundaries of the everyday and rethinking issues. For example, slowing down climate change requires the expertise of many disciplines: natural sciences, social sciences and law. We also cross borders in our collaboration with the universities on site: for example, with Graz University of Technology for 20 years in the NAWI Graz cooperation."

“Imagine a future, where we store green power in trees … with the newly invented ORGANIC BATTERIES for stable power grids”.
Student statement: “This video depicts how energy could be saved in tress and provide every home with it.”
Digital twin turns grids into renewable energy storage systems
The transformation of the energy system requires a gigantic expansion of the production capacities of renewable energy generation plants. Keywords here are electrification, heat demand, but also hydrogen or synthetic energy sources.
The electricity, heat and gas networks have a key role to play here. They smooth out the fluctuations in consumption and generation over the course of the day and the year. Flexibly switchable prosumers (consumers & generators) such as stationary e-cars, appliances or industrial plants help in this process.
All prosumers such as private households with PV systems or larger energy communities are actively involved.
These are complemented by point source large scale storage. Large hot water tanks bring summer heat to winter district heating. Redox flow batteries (with novel electrolytes made from paper production waste) support hourly and daily grids.
The grids interact with each other so that heat, electricity and gas help each other out. Peak load power plants, so-called “peakers,” will also be needed in the future to support the grid. With the help of hydrogen as intermediate storage, these will become climate-neutral.
The “network as a flexible energy sponge” is made possible by the first digital twin of the European electricity and gas network, including heating networks. This prevents blackouts at an early stage through simulations and contributes to the full use of generation from renewable energies.

“Imagine a FUTURE where SUN fuels life … directly with the new PHOTOCATALYTIC COLLECTOR”
Student Statement: “This video demonstrates a new technology that can be used to obtain hydrogen directly through sunlight and what areas this could be useful for.”
Hydrogen directly from the sun moves ships, among other things, in a climate-neutral manner
The use of green hydrogen is a key building block in the future energy system as energy storage as well as an energy vector also for future marine and aviation.
So far, work is underway to produce hydrogen in sunny and windy parts of the world using PV and wind power via electrolysis and then convert it, e.g. as synthetic fuels. This is costly and inefficient.
In the future, direct photocatalytic production of hydrogen without electrolysis will be used, a game changer for the important building block of the energy system of the future.
Trials are underway at AEE Intec for this purpose. This means that in addition to solar collectors (heat), PV systems (electricity), solar reactors (hydrogen) will now be possible in the future. The overall efficiency increases massively with decreasing costs.
Shipping is indispensable in the global economic and transport system, but is one of the world’s largest CO2 emitters. 90 percent of large ships still use heavy oil as fuel.
Austria, a landlocked country, has the potential to put global shipping on a new green path and reduce emissions by 97 percent: green hydrogen is used as liquid methanol on the ship, the resulting CO2 is captured, stored on the ship, and reused on land for the production of methanol (i.e., used in a cycle).

“Imagine a FUTURE with a FAIRYTALE life … using social TIPPING POINTS for faster climate action”
Statement of the students: “This video shows an awakening of society, which entails a fundamental change. Our values and norms have been strongly in tune with nature ever since.”
Faster than climate change
For all our faith in technological progress and the problem-solving abilities of Homo Sapiens, the news about natural disasters, weather extremes, the evident effects of climate changes that can already be measured, and the warnings of science force us to ask the central question: Can we still turn the tide quickly and effectively enough?
What picture of the future shows us that we were faster than climate change? That we have got a grip on the situation and have been able to steer the climate back towards more stable and livable paths?
On the one hand, it will be a matter of having won people over to the cause. So-called social tipping elements, on which the Wegener Center at KFU conducts research, will have captured people and brought them into action in a positive sense. Psychology and sociology as sciences can be an important key, and the use of new technologies such as artificial intelligence could also be a possibility to work here in the movement or activation of people. So everyone is pulling in the same direction.
Technically, however, it is also about scaling climate protection and circular economy solutions. The enormous amounts of energy, even with increasing energy and resource efficiency, must be produced in a 100% renewable way. To do this, technologies will become radically simpler and faster to use. New business models and a new way of doing business have revolutionized the world. An opportunity for the world, Europe, Austria, and especially the Green Tech Valley.
Styria & Carinthia were early pioneers in this field. More than 100 years ago, Viktor Kaplan invented the Kaplan turbine at the Graz University of Technology, the heart of the largest hydroelectric power plants in the world. And in the field of solar thermal energy, AEE pioneered a first wave for renewables with the self-assembly groups – the neighborhood joined in. With the first separate collection in Mureck, waste separation and thus recycling was widely started, especially in schools.

“Imagine a future society with zero waste … powered by 100% recycled batteries, organics & textiles”
Student Statement: “This video shows how we will achieve a waste-free future utopia through a 100% circular society. Innovative technologies such as self-healing substances and advanced recycling facilities will keep materials in circulation for as long as possible.”
100% circular society – A waste-free world through revolutionary approaches
Circular innovation is essential for a sustainable future. Consumption and modern life today are inextricably linked to waste. Packaging, surplus products, defective goods, food scraps and end-of-life products all contribute to the waste problem. However, waste is just a recyclable material in the wrong place. To enable a sustainable future, raw materials from the waste garbage can must be returned to the material cycle to enable a waste-free society.
No materials are disposed of after only a short period of use, but are kept in the cycle as long as possible through reuse, rethink, repair, remanufacture and also recycling processes.
In addition to the central, social dimension of a circular society, innovative technologies are also a building block: modern sorting plants that can ensure efficient separation of the various fractions, filter out materials that can still be reused, and allow the remaining substances to be used again in new ways through efficient chemical recycling.
Also, the development of self-healing materials that can repair themselves when damaged can extend the primary life of the product, contributing to a circular society. An extension of tracking individual materials is offered by digital product passports. These summarize all information about a product from components and materials to information about repairability & reuse.
New business models and distribution access such as leasing and sharing business models, product-as-a-service systems or performance-based contracting, can enable better maintenance and higher efficiency of use.
The renovation of buildings and the efficient recycling of construction waste are major contributors to the circular society. With digitalization as an important driver, e.g., through digital twin, which is updated throughout the life cycle, enabling a basis for later conversion and deconstruction measures.

“Imagine a future, where CO2 is on the plate, not in the atmosphere … powered by new bioreactors using recycled CO2 for sustainable food“
Student Statement: “The video showcases the dual potential of CO2: accelerating plant growth and transforming into protein powder for food production.”
Capture, store & use CO2 from various sources.
Climate change requires rapid and comprehensive reductions in CO2 emissions. In order to achieve the goal of “net zero emissions”, it is absolutely necessary to also bind CO2 emissions in order to cancel out remaining emissions in the balance sheet.
CO2 capture, especially from industrial or power plant waste gas streams, is already helping to reduce emissions. Andritz is currently scaling up a pilot plant for CO2 capture at cement plants. If biomass is burned instead of coal, a CO2 sink is created in the balance sheet.
Research at Graz University of Technology and the COMET Center BEST is investigating methods for additional production of green hydrogen from this process (bio-looping). Residual materials such as sewage sludge are also used in this process.
If the CO2 is then used as a material, emissions from the substituted products are again avoided. For example, acib and several startups are working on the extraction of proteins from CO2, which replace more climate-intensive animal feed. Methanation of CO2 via synthesis or hydrogenation processes also enables a sustainable energy carrier.
But farmers are also changing once again. With biogas & large PV plants they became “energy farmers”, in the future they will probably become CO2 sinkers: with the active build-up of the humus layer as carbon storage in the soil (especially by avoiding plowing, pilot region Kaindorf), with the introduction of biochar, i.e. charred biomass into the soil (research by BEST) as well as sustainably optimized forestry (special CO2 storage plants?).
Geological storage (cf. current prototypes in Denmark) will also be a building block on which little research is being done in Austria and which is not currently permitted here.

“Imagine a FUTURE of climate-active BUILDINGS … that STORE CO2 in new materials and timber constructions”
Student statement: “This video shows how building with natural materials and modular wood structures could reduce construction waste and collect CO2 to release into the atmosphere.”
Buildings as CO2 reservoirs
Buildings are currently seen as part of the problem rather than part of the solution to a climate-neutral future. Many building materials such as concrete, bricks, etc. contain a lot of gray energy and thus also CO2 emissions. More than 10 percent of the climate-relevant emissions in Austria can be attributed to the building sector.
The future image “Building as CO2 storage” shows the building as CO2 sink instead of CO2 emitter. More CO2 is stored in buildings than is emitted during the production of building materials or the entire construction process. The building becomes climate positive.
Forests and trees store carbon in biomass, for example in wood. When wood is installed in the building, this carbon continues to be stored, provided that the entire timber industry is also managed sustainably, in a cycle. Wood construction is therefore an already existing lever. Through buildings, the raw material wood can be kept in the cycle for hundreds of years.
There is still a big lever in the CO2-free production of concrete and bricks. With energy efficiency and the use of renewable energies in production, the first step succeeds, the use of CO2 captured in the industry and the storage in these building materials themselves creates the actual sponge function. The building surfaces (facades & roof) themselves are active, either green or generating electricity & heat.

“Imagine a FUTURE where cities are FORESTS … with organic surfaces producing green ENERGY”
Student Statement: “This video depicts the fusion of Graz with nature through various innovative developments and technologies, including sustainable energy production and vertical farming.”
Forest City
Nature and the city will no longer be mutually exclusive in the future. People are already aware that regeneration and health are to be sought in nature and that urban environments, as we know them today, tend to lead to stress and also health side effects.Green cities, or nature cities, can be thought of as forests in which nature and especially trees are given a very large space.
Furthermore, it is about area-wide organic, bioactive & energy-active surfaces (soils, facades, roofs, traffic routes) instead of sealed and passive surfaces. Here energy, food & oxygen is produced as well as water is stored.
CO2 sequestration is one function that the Nature City fulfills. The other is that of a city in which people feel comfortable because innovative and natural surfaces have a climatizing effect and produce oxygen. There are no more heat islands and the city is a CO2 sponge.
Energy efficiency and energy production including intelligent storage and distribution is part of the natural city. Food can also be produced directly in the city. On roofs and facades, in public spaces and through vertical farming, integrated into the other use functions of a city.
Nature is once again becoming a part of the reality of life for residents, and a sense of it is also being rekindled in schools. This additionally leads to more awareness for the protection of nature.

“Imagine a FUTURE with relaxing MOBILITY … enabled by research on AUTONOMOUS and ELECTRIC mobility”
Student statement: “This video shows an autonomous transport system that makes the vision of a car-free city come true. The Modular Transportation System offers the benefits of a private vehicle and allows individual or shared use of the capsules. These integrate seamlessly with public transportation.”
Electr(on)ically mobile – “Beam me up, Scotty”
The transport sector is one of the main sources of greenhouse gas emissions. The highest share of emissions in the transport sector is attributable to road traffic, and in particular to passenger car traffic. In Austria, the transport sector is responsible for around 25% of CO2 emissions. But we also want to be mobile in the future. Travel also broadens horizons and connects us. So what does the mobility of the future look like beyond public transport, cycling, energy efficiency and electrification?
Digitization is a big key to making a certain kind of travel obsolete. Video conferencing has already become part of everyday life. Virtual and augmented reality applications can certainly make a difference here. New worlds and meeting spaces can be a way of traveling.
Research at Graz University of Technology helped make the Microsoft Hololens possible. Paired with the appropriate hologram technology, “holoportation” – that is, 3D travel from home – becomes possible. Or will Anton Zeilinger’s quantum research lead to “real” beaming after all? Crypto research from Graz will probably be in future quantum computers.
Electric mobility and other forms of propulsion can be a bridging technology to completely new, today still science fiction, approaches. Ecological lightweight hybrid materials may play a role here (Wood Vision of Mobility). From fossil-based materials to renewable materials with cycle-based eco design. CO2 storage with negative CO2 footprint of the materials used in mobility solutions. New design languages and regional value chains from the forest to mobility.
