Design rules for a sustainable Bio-economy
People, Planet, Profit
● Improve efficiency of use of raw materials and energy
● Increase field yield but keep components on the field that are required for soil fertility
● Use all biomass components and choose the right raw material
● Use each component at its highest value:
(molecular) structure is much better than caloric
● Reduce capital cost to speed up innovation and to benefit from small scale without the disadvantages

Small scale biorefinery
● Lower costs for transportation towards factory and back!
● Year around for the precious unit operations
● Water and minerals stay on site
● Less waste treatment on factory
● More income to farmers
● Gradual development of market as well as sourcing raw materials
● Can cope with environmental regulation in the NL

• Biorefinery for feed, materials and chemicals will create good income for agriculture and enables even to compete with coal, natural gas and Brazilian biomass!
• Avoiding heat exchange and small scale processing reduces capital as well as costs for energy and transportation and
• will lead to higher employment
