Energy demands, pollution and global warming induced by globalization are rising, thus calling for alternative sources of energies. In particular, biofuels are increasingly used for transportation, electric power and heat energy generation. Biofuels can mitigate greenhouse gas emissions by up to 50%. Biofuels are produced from organic matter and waste such as dry lignocellulose, algae, yeast, restaurant greases, food grain, non-food grain and animal fats. Biofuel from crop residues can be promoted by government subsidies to reduce the fuel price and meet the requirement of industries, transportation and agricultural sectors.

使用生物过程生产生物燃料，生物柴油和生物氢。回顾

全球化引起的能源需求，污染和全球变暖正在上升，因此需要替代性能源。特别地，生物燃料越来越多地用于运输，电力和热能的产生。生物燃料可以减少多达50％的温室气体排放。生物燃料由有机物和废物（例如干木质纤维素，藻类，酵母，饭店油脂，食用谷物，非食用谷物和动物脂肪）产生。可以通过政府补贴促进作物残渣产生的生物燃料，以降低燃料价格并满足工业，交通运输和农业部门的需求。
