Aircraft manufacturers are increasingly turning to new manufacturing processes to save on fuel costs. More →




Organic waste becomes clean water

The Styrian company Botres Global is battling the organic waste in Ibiza. This accounts for 50 percent of total waste. Landfilling leads to the uncontrolled production of greenhouse gases, as organic waste is not separated from residual waste. Using unique technology, organic waste is now treated to produce biomethane, high quality fertilizer and clean water. In September 2020, the plant will be put into operation. More →




Largest solar thermal systems south of the Sahara

In Africa, the two largest solar thermal systems south of the Sahara were built as part of the AEE INTEC initiative "SOLTRAIN". This saves large amounts of electricity as measurements show that households in the region use 40 to 50 percent of their electricity for hot water. The annual solar yield of all built facilities under the initiative is 1.83 million kilowatt hours (kWh). This corresponds to avoiding 1,222 tonnes of CO2. More →




Wind & PV being turned into green gas

As part of a research project, Graz University of Technology, along with its project partners VERBUND and German firm Sunfire, is setting up a demonstration plant at the thermal power station in Mellach, intended to investigate whether carbon-neutrally produced hydrogen can be used in the plant as a replacement for fossil gas. The Hotflex pilot plant takes surplus wind and solar power from the grid and con-verts it to hydrogen using high-temperature electrolysis. A carbon neutral fuel, this “green” hydrogen is mixed with natural gas to drive the two gas turbines. More →




First Turn-Key Plastics Recycling Facility in the Island State

Every year, the summer sun, sea and sand attract growing numbers of tourists to the European island state of Cyprus. In addition to great sales for the tourism industry, they also generate steadily growing mountains of waste. Tourists are clearly not the sole contributors, but according to current figures, Cyprus has the second highest amount of waste per capita in the EU after Denmark. More →

Recycling of photovoltaic

The lifetime of the first-generation photovoltaics will end in the near future. The challenge is recycling the multiple million tonnes of modules. Until now components were disposed of as electrical scrap or waste glass. Research into more sustainable methods is at the heart of a consortium which includes the Styrian company PCCL and the University of Leoben. For instance, the glass in a module is a high-quality product which is too valuable to be mixed with glass from bottles or windows. A separate recycling process will be developed in order to fully recycle old PV glass. The results of the research also serve to make future PV modules more sustainable. More →
