RDF is a processed form of the combustible material found in MSW and is the final product of some resource recovery facilities resulting from a process line which separates and shreds incoming raw MSW. It typically has a nominal particle size of 2 in. or less and can be used directly as a fuel. However, since the moisture content is usually high and the bulk density is always low, it cannot be easily stored or transported which limits it to more or less immediate use at the site of production. We, and others, have been examining ways to overcome these problems and economically produce a fuel product which can be handled, transported and stored in a manner similar to other commercial fuels. Research in this area has concentrated on three main approaches: compression of the RDF to form densified refuse derived fuel or dRDF; fine-grinding the RDF to form powderized RDF or p-RDF and thermal/chemical conversion of the RDF to useful fuel products (pyrolysis, fermentation, anaerobic digestion). The authors have concentrated primarily on the first two of these alternatives. Specifically, they have been interested in chemical additives to improve densification, embrittlement and susceptibility to powderization. This report summarizes the authors' approaches to the evaluation of the toxicity of the ash samples and presents a comparison of the approaches based on preliminary data gathered to date.
