This study used ceramsite and superphosphate as exogenous additives for composting garden wastes. It investigated the changes in temperature, pH, lignocellulose, enzyme activity, humic substrates, and humification parameters during the composting process. A total of four treatments—T0 (CK), T1 (ceramsite), T2 (superphosphate), and T3 (superphosphate + ceramsite)—were tested in a 50-day composting experiment. It was found that the formation of the compost humic substrate could be increased to 14.69% under the action of ceramsite. In addition, ceramsite promoted lignocellulose degradation, improved enzyme activity, and enhanced the material conversion in the composting process. At the same time, superphosphate also promoted the formation of humic substrates in compost but was less effective than ceramsite. Ceramsite is the best additive in promoting compost maturation.
