16 <br /> ALTERNATIVE TECHNOLOGIES FOR VOLUME REDUCTION <br /> The feasibility of a regional solid waste management program should be <br /> based on proven technologies that will result in environmentally sound and <br /> reliable performance. It is also important that the selected technologies <br /> be of a type that will reduce the amount of residual or nun proce<ssible <br /> solid waste that rust still be landfilled by more than 50 percent. <br /> Based'on operational experience, the only technologies that can meet these <br /> criteria today are waste-to-energy incineration, and the composting of <br /> solid waste. Mass burn, waste-to-energy technology is capable of reducing <br /> the landfill disposal volume of municipal solid waste by about 80 percent. <br /> When coupled with a comprehensive source separation recycling program, 13DR <br /> is of the opinion that the combined reduction in volume could approach 90 <br /> percent. <br /> Refuse derived fuel (RDF) technology is capable of reducing the disposal <br /> volume of municipal wastes by 60 to 70 percent. When coupled with a source <br /> separation recycling program, HDR is of the opinion that the combined <br /> reduction in volume could approach 70 to 80 percent. <br /> { <br /> Finally, "the composting of municipal wastes can result in a 25 to 35 <br /> percent reduction in disposal volume of municipal wastes through the <br /> physical and biological process of organic decomposition. Were all of the <br /> compost to be marketed or given away, the total reduction in landfill <br /> volume could approach 60 percent exclusive of recycling. HDR does not <br /> believe this degree of volume reduction can be achieved because of market <br /> limitations. HDR is of the opinion that the coupling of a comprehensive <br /> ES - 6 <br />
