Global warming causes us to rethink our use of fossil fuels, our energy production and consumption. There is an urgent need to replace fossil fuels with renewable energy. This is why the European Union has set the 2020 target which means that by 2020 20% of our energy production should come from renewable resources. Energy from biomass is an essential component in that transition.
Anaerobic digestion is a form of renewable bio energy since it is energy produced from organic matter coming from plants. This organic matter is digested by microorganisms, which produce bio gas that is then transformed into electricity and heat in a combined heat and power unit.
Today maize is the major feedstock for anaerobic digestion but because of the competition between food and energy it is interesting to look for other feedstocks. In Europe a large quantity of grass is produced annually in nature and roadside management. The cutting and removal of these grasses increases the biodiversity but they are considered waste. Because of certain barriers the energy potential of grass and other herbaceous residues is highly underutilized across Europe. Barriers are insufficient awareness and acceptance of suitable technologies for the mowing, storage and anaerobic digestion of grass residues, absence or lack of cooperation between stakeholders along the value chain, as well as legal barriers. That is why GR3 promotes the use of these residues from landscape management as a resource for biogas.
