The resource recycling of organic solid wastes in urban and rural areas is crucial for the development of waste-free cities and a circular economy.The carbon peaking and carbon neutralization goals proposed by China also impose new and higher requirements for the resource recycling of these multi-source organic solid wastes in urban and rural areas.This study summarizes the basic progress of the resource recycling of multi-source organic solid wastes in urban and rural areas in China from the perspectives of household wastes,sewage sludge,and agricultural wastes,and identifies the prominent problems in overall planning and top-level design,collaborative management and cost mechanism,as well as technological innovation and transformation.Moreover,it proposes three key technical paths for the resource recycling,including multi-source collaborative recycling centered on biological treatment,multi-source collaborative safe disposal centered on thermochemical treatment,and intensive/park-based collaborative disposal of multi-source organic wastes.Furthermore,the following suggestions are proposed:forming the medium-and long-term overall planning and top-level design for pollution and carbon reduction,strengthening interdisciplinary integration and industry-university-research-application collaboration,and improving the institutional system by establishing a cross-departmental collaborative management system and a market-based pricing mechanism to promote the innovative application of key core technologies and industrial upgrading.
