Why biofermenter are vital to our future

Biogas plants are baseload-capable, they always supply electricity, even without wind and sun, and they supply an unencumbered biofertilizer for soil remediation. The biomass normally produced in agriculture, such as maize plants, energy grass, manure and manure, is fermented in a biogas plant and used to produce biomethane. Fermented, unencumbered fermentation residues are the best biofertilizer and far less aggressive than fresh liquid- or solid manure.

A promising alternative to corn

Second-generation energy grass "GreenStar".



The methane gas yield is comparable to maize:

approx. 100 m³ / t FM

GreenStar: a horst forming giant wheat grass with the following characteristics:

  • deep-reaching root system
  • dry tolerant
  • very hardy from 3-leaf-stage
  • long-term growth into October
  • forming humus
  • with high germination capacity
  • perennial
  • persevering
  • low soil requirements make the plant ideal even for weak soils
  • Advantage by reducing the gross acreage
  • Unlike many other energy plants, such as the silphium perfoliatum also called cup plant, the perennial energy grass Greenstar can be drilled with conventional technology
  • less space needed for greening
  • Biogas yield comparable to maize
  • significantly cheaper than corn
  • the property that unlike many other energy crops, such as Perennial Silphie, the multi-annual Greenstar energy grass can be drilled by using conventional techniques and is less susceptible to UV and fungal attacks
  • Corn comparable biogas yield due to higher green mass
  • significantly lower cost than corn

The initial development of GreenStar after sowing is restrained, requiring weed control. The economically profitable use is about 7 years.

A new possibility and opportunity for agriculture:

Agrophotovoltaic systems

Agrophotovoltaic systems have already proven to be practical. The investment costs are already competitive with solar roof systems. The results of reference systems are promising.

AgroPV plants are highly economical.

Fraunhofer reference systems

Agro Pv- System for GreenStar Energy grass or Energy maize: Harvest with shredder and loader wagon width: 12,0m, passage height 6,5m


"The results of the first year of the project were a great success as the Agrophotovoltaic system has proven to be practical. The cost compared to a small solar roof systems are competitive and the harvested products can be marketed sufficiently high and economically viable"explains Stephan Schindele, project manager for Agrophotovoltaics at Fraunhofer ISE.

"The Agrophotovoltaic (APV) has the potential to create new land for the urgently required photovoltaic expansion in Germany and at the same time to reduce the land conflict between agriculture and open space systems. With a constant shortage of soil resources for the production of agricultural products, Agrophotovoltaic is an important solution through the double use of arable land.

It is essential to produce more food and energy in parallel and at the same time conserve water, soil and climate without chemicals and pharmaceuticals.

The part of biomass in household waste is around 50% worldwide.

The power generation of this biomass via biogas plants is an important contribution to providing the required electricity as renewable energy and relieves the atmosphere.
