摘要： With the development of urbanization, kitchen waste and garden waste have become an important part of municipal solid waste (MSW), which is in urgent need of resource treatment. This study investigated the impacts of garden waste as auxiliary materials on maturity and odor emissions (NH3 and H2S) during kitchen waste composting. The result showed that the combined composting product of kitchen waste and garden waste achieved the maturity effect, and the co-composting effect was better than that of separate composting of kitchen waste. Meanwhile, compared with the separate composting treatment of kitchen waste, the co-composting treatment of kitchen waste and garden waste can effectively reduce the cumulative emissions of H2S by more than 85%, and effectively reduce the cumulative emissions of NH3 by more than 75%. This study provides a technical reference for the green fertilizer utilization of kitchen waste and garden waste.
