As existing landfills become filled to capacity and new landfills become more costly to site, the development of alternative disposal methods of municipal solid wastes (MSW) is becoming critical. In addition, the refuse being buried contains considerable quantities of energy that could potentially replace conventional fossil fuels. Some of the main problems of using MSW as a feedstock have been variability, biological and chemical instability, and poor fuel quality. An improved method for turning MSW into an environmentally safe and economical fuel has recently been developed. Recyclable metals, glass and some plastics are mechanically and manually separated from the waste. The remaining (combustible) fraction is combined with a calcium hydroxide binding additive, and formed into cylindrical pellets. These pellets are dense and odorless, can be stored for up to three years without significant biological or chemical degradation, and are easily transported. These pellets have been successfully confined with coal in existing spreader-stoker combustors. Other benefits include significant reductions of sulfur dioxide (SO{sub 2}), nitrogen oxides (NO{sub x}) and CO{sub 2} in the flue gases, and the trapping of the chlorine combustion products (such as HCl) that are formed during the combustion process from the remaining plastics in the refuse. This paper describes the b-dRDF pellet/coal cofiring tests, emission and ash samples collected, analyses that were conducted on these samples, and study conclusions. 6 refs., 11 figs., 13 tabs.
