Energy park & Donau-Silphie: a symbiosis that benefits nature

Biogas plants that produce non-fossil fuels are very much in vogue at the moment. In the Swabian hamlet of Hahnennest, four family farms have joined forces to form an energy park and operate a local biogas plant, covering everything from substrate production to the sale of energy.

For quite some time now, the European Commission (EC) is putting a special focus on biodegradable and compostable polymers when assessing the general role of bioplastics.

Paper production from plant fibres - 20/01/2021

In one cycle: ecopaper, energy and fertiliser made from Silphium perfoliatum

Many consumers don't care about exactly how their paper packaging is made and what it is made of as long as it is "eco". But even producing recycled paper, trees need to be felled. An alternative could be paper made from cup plant. Together with partners, a company called Silphie Paper has developed concept for obtaining fibres for a new type of grass paper, while also producing heat, energy and nutrients for natural fertilisers.

The wastewater treatment plant is turned into a vegetable farm, bio-based substances recovered from waste are being utilized to prevent oxidative spoilage in food packaging or provide environmentally-friendly and safe water-repellent coatings on functional textiles. In the EVOBIO project coordinated by Fraunhofer IGB, 19 Fraunhofer Institutes are working on solutions for a sustainable economy.

In a review article recently published in the scientific journal Waste Management, ATB scientists outline the possibility of using insects to efficiently and sustainably recycle food waste. This insect-based bioconversion can help to close material cycles in the food value chain.

Wood energy – heating with wood – interview with Stefan Pelz, HFR - 10/02/2020

Wood: a cornerstone in energy transition

While a good third of the electricity in Germany now comes from renewable energy sources, the production and supply of heat from renewables has stagnated at around 11.5 percent. Energy from biomass, mainly wood and biogas, accounts for over 80 percent of the renewable energy produced. Bioenergy municipalities show how locally available, renewable raw materials and solar power can be intelligently combined for supplying energy.

Residues from biogas plants as feed for algae

Algae are frugal organisms. They require only light, water, minerals and carbon dioxide to be able to produce biomass. These properties will now be exploited economically in a two-year research project. Dr. Stefan Sebök from the University of Hamburg plans to study the holistic utilisation of degradation products of a biogas plant in Wallerstädten by linking them to land-based algae cultivation.

Celeriac and electricity: dual-use system on arable land

Food or fuel? Potatoes or electricity? In addition to growing energy crops for biofuel and biogas production, open space solar plants also compete with food production when it comes to land use. Agrophotovoltaics (APV), i.e. the dual use of arable land, can mitigate the conflicting interests of agriculture and open space PV systems. APV-RESOLA is a pilot project aimed at investigating the efficiency of this dual use.
