| Abstract: | Solid wastes such as municipal solid wastes (MSWs) are increasingly produced with complex components, and greenhouse gases are generated in the process of disposal, so the effective management of such solid wastes and the carbon emission reduction have become a hot topic of current concern.The current status of MSWs treatment and the standards of solid recovered fuels at home and abroad were introduced, the processes of biological drying and mechanical sorting technology included in the mechanical biological treatment technologies were described, and the potential problems in the combustion process of solid recovered fuels were analyzed. Combining the effects of conventional treatment and mechanical biological treatment of MSWs, the calorific value of solid recovered fuels after mechanical biological treatment was obtained to reach 10 536 kJ/kg, which was three times higher than the calorific value of virgin waste and did not require the addition of auxiliary fuel for combustion. The application of solid recovered fuels in cement and electric power industries could improve the effective reuse of resources and reduce the use of fossil fuels, which was important for cost saving, environmental protection and promoting the process of waste separation and carbon neutrality in China. |
