How to produce bioenergy from agricultural resources without harming the environment
•The overall managed area today
(including chopped area) is 1300 ha
•Of that appr. 500 ha was mowed and
balled last year
•The first phase is restoring the
flooded meadow

•Raw ash 3,50 – 5,95 %
•Raw fiber 28,89 – 33,25 %
•Metabolizing energy when feeded to
cows: 8,2 – 9,0 MJ/kg
Perspectives

– Hay as an organic fuel (burning)
– Biogas production
• Hay for making compost
Problems
