| Abstract: | Recycling of organic solid waste is an important task for pollution control and carbon reduction and waste-free city construction in China, and an important grasp of green and low-carbon circular development. The current situation of production and treatment of organic solid waste from different sources in China is summarized, and policy documents related to organic solid waste such as waste-free cities and pollution reduction are sorted out. Based on the characteristics of organic solid waste, easy to decay and high moisture content, as well as its dual properties of pollution and resources, the basic concept of harmlessness as the goal and resourcefulness as the means is proposed. The organic solid waste is a complex system with multi-media and multi-component interaction, and the research progress and technical difficulties in biological transformation, thermochemical transformation, solid-liquid separation and product resource utilization are summarized and discussed. The key breakthrough directions of organic solid waste are proposed, aiming to provide references for the technical research of resource-based treatment and disposal of organic solid waste in China. |
