Food wastes, municipal solid waste, as well as Industrial, Commercial & Institutional wastes and agricultural wastes pose a risk to human health and the environment such that they merit special management. Currently, the cheapest and commonly used management technologies for these wastes are landfilling or combustion. However, landfill releases methane and other greenhouse gases. Moreover, it has potential to pollute surrounding soil and groundwater. Hydrothermal liquefaction technology could convert carbonaceous waste streams into biocrude oil that is environmentally green but pose several challenges including high production cost and effluent product identification. There is compelling need to develop an economically viable production process of biocrude oil and analyze the component in the product in order to add value to underutilized waste. The objectives of the proposed study are to: (1) produce fuel and chemical products from food wastes, municipal solid wastes and Industrial, Commercial & Institutional wastes by using hydrothermal liquefaction; (2) develop an eco-friendly separation process in order to separate oil from the solids; (3) optimize the process parameters for catalytic upgrading of the biocrude oil for commercial applications; (4) perform material and product characterization studies; and (5) perform techno-economic analysis for accessing process safety and environmental issues. NULIFE GreenTech in Saskatoon, Canada is the industry partner for this proposed research. The technology developed from this study will be implemented at NULIFE GreenTech's production facility for manufacturing biocrude oil and biochar. The intended hydrothermal liquefaction facility with automated reaction system will allow Prof. Ajay K. Dalai at the University of Saskatchewan and his collaborators including NULIFE GreenTech to conduct hydrothermal liquefaction of diverse Canadian biogenic wastes that is indispensably needed in-house for the experimental and theoretical aspects of waste conversion to biofuels and fine chemicals.**

食物废物、城市固体废物以及工业、商业和机构废物和农业废物对人类健康和环境构成风险，因此需要进行特殊管理。目前，这些废物最便宜和最常用的管理技术是填埋或燃烧。然而，垃圾填埋场释放甲烷和其他温室气体。此外，它有可能污染周围的土壤和地下水。水热液化技术可以将含碳废物流转化为环境上绿色的生物原油，但会带来一些挑战，包括高生产成本和流出物产物鉴定。迫切需要开发一种经济上可行的生物原油生产工艺，并分析产品中的成分，以便为未充分利用的废物增加价值。本研究的主要目的是：（1）利用水热液化技术从餐厨垃圾、城市固体垃圾和工业、商业和公共事业废弃物中生产燃料和化工产品;（2）开发一种生态友好的分离工艺，以便从固体中分离油;（3）优化生物原油催化改质的工艺参数，以用于商业应用;（4）进行材料和产品特性研究;（5）进行技术经济分析，以评估工艺安全和环境问题。加拿大萨斯卡通的NULIFE GreenTech是这项拟议研究的行业合作伙伴。这项研究开发的技术将在NULIFE GreenTech的生产设施中实施，用于生产生物原油和生物炭。预定的水热液化设施与自动化反应系统将允许教授Ajay K。萨斯喀彻温大学的Dalai和他的合作者，包括NULIFE GreenTech，对各种加拿大生物废物进行水热液化，这对于废物转化为生物燃料和精细化学品的实验和理论方面来说是不可或缺的。
