The generation of municipal solid waste (MSW) is increasing annually worldwide. Reasonable disposal of MSW can not only avoid environmental pollution risks, but also contribute to resources recycling. In this paper, MSW was compressed to solid recovered fuels (SRF), and the influence of moisture content and composition of MSW and molding pressure on the expansion rate and impact resistance of SRF were analyzed. The results show that increasing the proportion of paper or reducing the proportion of plastics can reduce expansion rate and increase impact resistance of SRF; and reducing the proportion of fruit peels, or increasing the proportion of nutshells and textiles appropriately can enhance impact resistance of SRF, while ensuring good expansion rate. The calorific value of SRF prepared in this experiment meets the requirements of relevant standards of ISO TC300 and can be traded as a fuel product.
