Our contribution to the circular economy in the agricultural sector. Our solutions get the most out of your biogas and digestate. Put your trust in over 20 years of experience and innovative strength.
Focus on the circular economy
The agricultural industry is a significant consumer of fossil fuels and chemical fertilizers. It is the objective of most countries through government policy to reduce this reliance from an environmental and sustainability perspective. Renewable energy sources are simply inexhaustible – we only have to use them!
In the early 1990’s, the first framework conditions were created in Germany in order to promote the development
of renewable energy systems. The introduction of the “Erneuerbaren Energien Gesetz” (EEG – Renewable Energies Act) in 2000 allowed the development of the highly progressive “Renewable Energy” Industry. Today, approx. 50% of the German electricity consumption is already being produced from renewable energy sources.
Utilisation of Biogas
Combined heat and power units (CHP), with their versatile applications, currently represent an economical and efficient climate protection technology. All CHP units work according to the principle of combined heat and power (CHP), a decentralised generation of electricity and heat available directly on site where it is consumed. agriKomp offers you customised energy concepts for CHP applications. We develop optimised CHP units with modern engine technology from renowned manufacturers, such as SCANIA, in the small and medium power range.
The biogas produced is a mixture of approx. 50 – 75 % methane, 25 – 50 % carbon dioxide plus trace gases such as hydrogen sulphide, oxygen, nitrogen, ammonia, and hydrogen. Biogas can be used to generate electricity and heat in CHP units but often the full energy potential is not utilised. By upgrading biogas to biomethane, this full energy potential can be realised along with many other positive characteristics and possible applications.
The next generation of digestate treatment
The storage and use of slurry and digestate is leading to an increasing financial burden for biogas plant operators. Most of the processes currently available on the market work on volume reduction and concentration of nutrients. So far, however, no process has been able to remove excess nitrogen from agriculture.
The high nitrate levels in the soil and groundwater are due, among other things, to over fertilisation with ammonium- containing slurry, digestate and solid manure. A large part of the ammonium used becomes nitrate in the soil.
