Adopting waste-to-bioenergy technologies as waste management practice can provide dual benefits ofdiversion of waste from landfills and recovery of value-added resources. Thus, waste can be sustainablyutilized as a valuable resource rather than treated as waste. Anaerobic digestion, which is by far the mostwidely implemented waste-to-bioenergy technology for conversion of the organic fraction of municipal solidwaste to methane. However, anaerobic digestion of a single waste stream can sometimes be challenging due toinadequate nutrients and presence of toxic or inhibitory compounds in the feedstock. Co-digestion ofcomplementary waste streams is a promising engineering approach to overcome these difficulties via nutrientsbalance and dilution of toxicants, which ultimately enhance methane production. In collaboration with GHD,the proposed research will investigate co-digestion of food waste and sewage sludge for improving processstability and digestion performance.

采用废物转化为生物能源的技术作为废物管理做法，可带来双重效益，即把废物从堆填区转移，以及回收增值资源。因此，废物可以作为一种宝贵的资源可持续地利用，而不是作为废物处理。厌氧消化，这是迄今为止最广泛实施的将城市固体废物的有机部分转化为甲烷的废物生物能源技术。然而，单一废物流的厌氧消化有时可能是具有挑战性的，因为原料中存在营养不足和有毒或抑制性化合物。互补废物流的共消化是一种很有前途的工程方法，通过营养平衡和有毒物质的稀释来克服这些困难，最终提高甲烷产量。与GHD合作，拟议的研究将调查食物垃圾和污水污泥的共同消化，以提高过程稳定性和消化性能。
