8 The challenge A standard tractor can not move on the land Low-lying, often small areas with soft soil along streams and lakes Fine nature which depends on an extensive farming The farmer has typically no production on these areas more EU subsidies with an obligation to cut the vegetation SIDE 8

9 Purpose and goal Grass to gas : to demonstrate gentle harvest of biomass in meadows to streamline the production process, from harvesting to transportation to the biogas plant to achieve low mechanical and transportation costs, so it can contribute to make the care of these areas into a business for both farmers, contractors and biogas plants SIDE 9

15 The average on total 315 ha Annual production from 1 ha meadow Fresh weight in tons 13.0 Average % dry matter 37 Average tons dry matter 4.8 The vegetation from 1 ha meadow can in a biogas plant produce m3 methane gas = 1 year of heating a home with four people SIDE 15

29 Potentials for reducing the costs and increase the value of the biomass - A long harvest period (July-August and September) - Incentives to make the farmer interested to harvest the biomass - Exploitation of the machinery to other purposes - Developing a transportation system (without ground contact) with containers for transport by trucks - Develop settlement system of grass from the meadows in relation to harvesting quality and the potential for gas production - Helping to make biogas plants more suited to exploit meadow grass - Increase the value of the degassed biomass SIDE 29

31 Harvest of biomass on soft soil, in the coming years 2017: Harvest of biomass on 100 ha : Two years harvesting on 225 ha/year : Two years harvesting on 360 ha/year : Two years harvesting on 450 ha/year LIFE IP : Two years harvesting on 630 ha/year SIDE 31
