With the growing concern over climate change and the global depletion of energy and natural resources, there is a pressing need for rapid shift to renewable sources of energy and chemicals. Meanwhile, the ongoing surge in the planet's urban populations and modernization has resulted in the ever increasing production of biosolids that are often disposed as waste. However, these biosolids are renewable sources of organic matter and can be converted to energy and valuable chemicals. In Canada, wastewater treatment plants produce in excess of 660,000 dry tonnes of biosolids per year and this amount is expected to increase as new and upgraded facilities are constructed under the Canada-wide Strategy for the Management of Municipal Wastewater Effluent ratified by the Canadian Council of Ministers of the Environment (CCME) in 2009. More recently, in 2012, CCME approved a new national policy that requires the beneficial use of valuable resources in municipal biosolids. A similar trend is observed elsewhere in the world. The total sludge production in 15 European Union countries increased by about 50% from 1984 and reached 10 M t/year in 2010, and in China wastewater treatment plants are expected to generate 10 M t/year biosolids by 2015. Therefore, extracting value from biosolids through conversion to biofuels and bio-based chemicals will reduce waste and lower the overall greenhouse gas emissions.

随着人们对气候变化和全球能源和自然资源耗竭的关注，迫切需要快速转移到可再生能源和化学物质的来源。同时，地球城市人口和现代化的持续激增导致了经常被视为废物的生物固体的产量不断增加。但是，这些生物固体是有机物的可再生能源，可以转化为能量和有价值的化学物质。在加拿大，废水处理厂每年生产超过660,000吨干燥的生物固体，预计该数量将增加，因为加拿大范围内的新设施是根据加拿大范围内的加拿大废水管理策略构建的，该策略是由CCME（CCME）在2012年开发的，这是由加拿大的国民委员会（CCME）批准的。市政生物固体的宝贵资源。世界其他地方也观察到类似的趋势。从1984年起，15个欧盟国家的总污泥产量增长了约50％，2010年达到10 m t/年，预计到2015年，预计在2015年的废水处理厂将产生10 m t/年的生物固醇。因此，通过转化为生物燃料，从生物固醇中提取价值，并且基于Bio的化学物质将减少浪费并降低浪费并降低整体温室气体的降低。
