Climate protection and CO2 emission reduction
Bio-energy from organic rest materials
‘Green’ Asphalt production (draft for Kootstertille,…)
Anaerobic Digestion Plant• Input: 40.000 tonnes fruit waste and vegetable waste• Production
• electricity: 50 TJ(e/Annum• biogas: 1,7 million m³/Annum (37 TJ/Annum)• excess heat:5 TJ(th)/Annum
Asphalt production Kootstertille• Production
• Asphalt: 2 million tonnes/Annum• Consumption
• Electricity: 4,3 TJ(e)/Annum• Gas 2.5 million m³/Annum (55 TJ/Annum)

Bio-energy from organic rest materials
Proposed prohibitions and priorities
• dumping prohibition digestable products• no export of digestable products• no aerobic decomposition processes
• give priority to sustainable energy to the grid• consider digestate as compost or fertilizer substitution, not to be´waste´

(draft for Wijster)
• Annual raw material need: wheat 250.000 tonnes
• Annual production of energy, food and feed• energy: ethanol 80.000 tonnes (100.000 m3)• food: gluten 25.000 tonnes and bran 40.000 tonnes• feed: dried distillers grains with soluables 40.000 tonnes
• Annual CO2 emission reduction and efficiency• advanced ethanol production process with use of excess heat
• 140.000 tonnes – 90 %• conventional ethanol production process without use of excess heat
• 65.000 tonnes – 45 %

Discussion
Legends (Questions) ! ?
1. Renewable resources do not contribute to climate protection ! ?
2. Energy crops are ‘area’ competitive with food ! ?3. Using renewable resources for energy leads to
rising food prices ! ?4. In Asia and South America rainforests are cut
down, so fuel tanks can be filled with palm oil ! ?5. A sustainable energy supply is also possible
without the use of renewable resources ! ?6. Sustainable bio-energy is an opportunity for
regional economical development ! ?7. ……………………………….. ! ?
