摘要：

Recycling and converting the loose refuse and sludge into densified fuels (S-RDF) is promising for energy pro-duction, in which the sludge could be a suitable binder that can be combusted adequately for treatment. The increase in the sludge content and compress pressure positively influenced the physical properties of the S-RDF. Especially, the S-RDF with a mass content of 20% of sludge performed the favorable density of 1.2 g/cm3 and featured an abrasive resistance of 6.542% when the pressure was only 1 MPa, being similar to the RDF being compressed at 4 MPa without sludge. Also, it can be pelletized on industrial scale with a power of 7.5 KW. The results confirmed the positive effect of the sludge on the physical properties of RDF. S-RDF has a high calorific value of 2.25 x 104 kJ/dm3, and the ignition loss of S-RDF slag is low to 2% due to the promoting combustion of sludge by flammable waste. Thus, it is promising to facilitate the recycling and conversion of refuse and sludge into energy to address sustainable development.
