Info

Amounts and Problems 700 million tons of various crop straw are generated every year in China ~50% are used as feedstock, animal bedding, construction materials, soil amendments, etc… The rest is burnt in open field Fire disaster! Air pollution! Traffic accident!
Utilization as bio-resources As fuels: Burn directly smoke… Pyrolysis tar… Gasification char… As substrate: Ethanol fermentation long way to go… <strong>Anaerobic</strong> digestion comparatively reliable! ——produce bioenergy & reduce the pollution <strong>from</strong> crop straw
