Study on the feasibility of RDF production from combustible components of MSW in China

Experimental study was carried out for RDF production from combustible components of MSW (Municipal Solid Waste) on the first RDF production line with a daily output of 6 ton in China. Technical feasibility, operation cost as well as environmental impacts were investigated in the study. The method for defining the molding characts was presented in this paper. Effects of moisture, calcium content and drying method on RDF molding character were studied. The result showed out that the RDF preparation method is feasible in China. Although currently the cost is relatively high, it is anticipated to decrease dramatically with the enlargement of the preparation scale. The combustion characteristics of RDF were studied by means of thermogravimetry. The result showed that RDF, with heat value almost the same as that of hard coal, is a kind of high-quality fuel and can be used as alternative fuel.
