19 <br /> no solution will be risk free. However, it is imperative that <br /> environmental acceptability be demonstrated for an alternative to be <br /> feasible. The ability to site, permit, and operate any solid waste . <br /> management facility will depend on the ability to mitigate significant <br /> environmental impacts. These impacts can be mitigated through special <br /> design features, siting (i.e., mitigation by avoidance), or add-on <br /> pollution control technology. <br /> CONCEITS FOR REGIONAL SYSTEMS USING ALTERNATIVE TECHNOLOGIES <br /> LOGIES <br /> conceptual systems for mass-burn incineration technology, refuse derived <br /> fuel technology and solid waste composting technology were evaluated for <br /> the purpose of making comparisons and to evaluate the overall feasibility <br /> of utilizing these technologies to solve the future solid waste disposal <br /> crisis on a regional basis. The studies which have been performed indicate <br /> that only mass-burn incineration and solid waste composting appear to be <br /> feasible solutions for management of the non-recycled solid wastes. Of <br /> these two technologies, only mass-burn incineration appears to be fPAgible <br /> on a regional basis and offers clear advantages over development of <br /> separate mass burn waste-to-energy facilities in each County. Solid waste <br /> composting is a proven technology, but historically has been burdened due <br /> - • to:a;lack:of'reliable markets for the compost material. Were the <br /> I t <br /> technology to be utilized in the study area, HDR assumed that the system <br /> would be based primarily on the burial of the composted waste in a landfill <br /> facility. There does not appear to be a clear economic advantage to the <br /> development of a single regional compost/landfill system, and the total <br /> required site size may cake the facility very difficult to site.
