In this work, the kinetic behaviors and thermodynamic characteristics of aged refuse (AR) and municipal solid waste (MSW) under distinguishing conditions (blending ratios, heating rates, oxygen concentrations) had been investigated. Combining a low proportion of AR would promote the combustion of MSW, and 10%AR presented the best activation energy E-exp (166.62 kJ/mol). For the 10%AR, the heating rate of 40 degrees C/min can reach the best comprehensive combustibility S (29.14%(2)degrees C(-3)min(-2)) and the burning temperature range had increased to 270.6 degrees C727.6 degrees C. When the oxygen concentration changed from 10% to 30%, the residual mass M-f dropped from 29.52% to 14.24%. This paper proposes a recycling strategy of AR by mixing combustion with MSW.
