Advanced electric drive for mobile biomass processing

Komptech has launched a new mobile star screen machine with over-length return, for the processing of recycled timber and biomass, that has the highest level of efficiency due to the advanced electric motor drive. All machine components (such as the screen deck and conveyor belts) are electrically driven. Compared to hydraulic drives, this results in significantly lower energy consumption. In addition, there is an on-board hybrid drive for the drive power, which reduces energy costs by up to 75% when connected to the electricity network. This gives potential savings in CO2 of up to 6.5 tonnes per year, per machine. More →

Graz University of Technology develops hybrid energy storage

Electric mobility of the future requires a new generation of energy storage systems. Up till now, battery systems in electric cars have been used in conjunction with super condensers; two systems which could not be more different. Batteries store large amounts of energy and release them slowly. Super condensers, on the other hand, store only small amounts of energy, but can deliver them with much greater power. Now a research group, formed around the Graz University of Technology, has succeeded in developing a storage method that combines the advantages of both systems. More →




New Styrian K project for digital waste management

Six of the seven competence centres, which have a strong focus on environmental technology, will in future be located in Styria. And with the recently approved K projects there is an equally impressive show - seven out eight with Styrian participation. The “ReWaste 4.0” project is one of them. It is concerned with networked recycling processes and is supported by a consortium, which includes the cluster partners Montanuniversität Leoben, Anton Mayer GesmbH, BT-Wolfgang Binder GmbH, Komptech GmbH and Saubermacher Dienstleistungs AG. Other environmentally focused projects approved within this call for proposals are “SafeBattery” and “WoodCar”. More →

Pivot plants for the irrigation of a total area of 14,000 ha/year as well as Rainstar drum irrigation machines for 5000 ha/year are now being produced in the factory. In a further stage of development, equipment for wastewater, such as separation, pumping and stirring technology, will be manufactured. More →




Intelligent recycling plant for Malaysia

ANDRITZ MeWa supplies the first automatic recycling plant for refrigerators and electronic scrap to Penang, Malaysia. Starting in the middle of 2017, around 300,000 refrigerators and up to 60,000 tonnes of e-scrap, such as washing machines, household appliances and computers, will be processed there annually. The central element is the QZ 2000 cross-flow shredder, which separates the individual fractions and separates out batteries and capacitors without pollutants. In addition, the encapsulated system ensures that released gases, such as CFCs and pentane, are extracted and disposed of in an environmentally sound manner when processing refrigeration and air-conditioning units.

Fewer chemicals in electroplating for the first time

For the first time, AEE INTEC, together with Rotreat, has succeeded in making a fully automated processing plant suitable for electroplating baths based on a technology not normally used for electroplating, namely membrane distillation. During the production cycle, electroplating baths are continuously diluted and the chemicals are regularly replaced. By the use of membrane distillation, the process water is extracted and the desired quality is achieved without additional chemicals. This environmentally and resource saving innovation has gained them the ACR Cooperation Award. More →




Prefabricated Roofboxes Create New Living Space on Multi-Storey Building Roofs

The new Roofbox from AEE INTEC and its partners is the advanced solution for meeting the growing demand for accommodation space, especially in urban areas. The prefabricated timber room modules can be placed on existing buildings, attached to them or used as an independent, barrier-free house. The room modules are delivered as prefabricated units, together with a photovoltaic system, so they offer distinct advantages in fast construction time. You can currently visit the show site of the company at Haas Fertigbau, in Großwilfersdorf. More →

Facility opens for industrial battery recycling

The Saubermacher subsidiary REDUX has its sights set on becoming the European market leader in battery recycling. Around 80% of batteries, such as alkaline-manganese or zinc-carbon cells, are recycled at the Offenbach am Main site. The new treatment plant separates up to 25,000 tonnes of batteries per year into individual components that are reused as secondary raw materials. This is the first time that recycling of the batteries has reached an industrial scale. More →




Wind turbine for buildings ready for mass production

BLUE POWER develops highly efficient wind turbines from 1 kW output for private consumers up to 10 kW output for companies. The sophisticated nozzle principle enables higher performance of up to 30% with virtually noiseless operation. This is achieved by using CFD simulations (computational fluid dynamics) at the design stage in order to improve the flow behaviour and performance as far as possible and to minimize the noise pollution. As a result, the wind turbines are a great success in residential areas due to the covered structure. The wind turbines are currently ready for series production. More →




Styrian know-how for China’s waste

Within half a year, REDWAVE, the specialist plant supplier, has already won the second contract to supply a mechanical-biological waste treatment plant to China. This MBT plant processes 650,000 tonnes of household waste annually and should be ready to go into operation in early 2018. This is truly a record, as the contract worth over € 24 m. is the largest single order that the Company has gained to date and the largest such project in China. In the new plant, waste is first dried and then treated mechanically. Through the drying process, recyclables such as ferrous and non-ferrous metals are recovered and inert contaminants such as glass, stone and ceramics are separated out. More →




SOLID sets new solar standards in Nicaragua

The solar systems specialist is equipping a hospital in Nicaragua with a large thermal solar installation for air conditioning and hot water supply. The 4,450 m2 system will in future cover the whole of the hot water demand for the building and at the same time the air conditioning for sections of the building. The € 4 m. contract will thus save about 1,100 tonnes of CO2 annually. The innovative company is highly regarded and recently won the Intersolar Award 2016 for efficiency and innovation with the solar cooling installation at Desert Mountain High School in Scottsdale, Arizona.

Styrian eco-concrete yields up to 30% savings in CO2

Graz University of Technology has developed a “green” concrete, which generates up to 30% less CO2 in the production compared to standard concrete. The secret lies in the new mixing ratio. Concrete is made up of various aggregate particles, water and binder, and includes Portland cement, which is fired at 1450°C with a great expenditure […] More →




New plant for high-quality raw materials

The new Saubermacher waste treatment plant in St. Michael will sort, crush and separate 20,000 tonnes of WEEE (Waste Electrical and Electronic Equipment) every year. At the premises of Anton Mayer, the Upper Styrian waste management company, valuable secondary raw materials such as steel, zinc, copper and plastics will be recovered from mobile phones and toasters etc. Over a process of between 10 to 15 steps, 85% of the waste is recovered as recyclable material and about 10% is incinerated. The great advantage of the new system lies in the high flexibility, which allows the production process to be adapted individually to the resulting material flows. More →
