Sustainable bio-energy Regional Innovations in Bio-energy, Food and Feed Production Onno van Dijk project manager life sciences
World energy consumption and (non) renewable energy (1)

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 Gas2.5 million m ³ /Annum (55 TJ/Annum)
Separated collection Asphalt production ‘Green’ asphalt Anaerobic digestion plant Fertilizer substitution Vegetable waste and fruit waste Grass Grass verges and parks Remaining materials like wood, paper, glass and plastics) Manure Digestate Organic rest materials Leafs and straw Feed ‘Green’ asphalt from ‘green’ energy out of organic rest materials Food Biogas “Green’ energy out of organic rest materials ! Composting CO 2 !
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´
Greenn Co (2) (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 m 3 ) food: gluten 25.000 tonnes and bran 40.000 tonnes feed: dried distillers grains with soluables 40.000 tonnes Annual CO 2 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 %
Kg/ha Renewable resources and agricultural research Breeding system combining crop rotation and inter cropping Peas and rye Triticale Kg/ha Landscape maize Months
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.……………………………….. ! ?
