"r~te.'.Ot:her factors th&t: are important are the availab[lit:y of nutrients and bacteria. Liqul <br /> will be added to the refuse by the addition of fresh water~ by,the recycling of Ieachate iht, <br /> the refuse, and by the addition of wa.stewater and lime sludges. 11/ast:ewater sludge will aL~ <br /> add nutrients and bacteria seed. Lime sludge will also act to buffer the pH of the refu~ <br /> moisture. <br /> <br /> The accelerated decomposition landfil! will be underlain by a double liner syst:em <br />Leachate wilt be collected with a collection system placed above the upper Liner. A lea~ <br />detection/secondary leachat:e collection syst:em, will be placed between the two Liners <br />a~sess :he effectiveness of the upper liner. If a leak should develop in the upper liner, the <br />secondary system wLl! collect ~ny leachat:e movin& through the upper Liner. <br /> <br /> Fresh water and reclrculat:ed leachate wLU be added to bring the refuse to the propez <br />moisture content for rapid decomposition. Alter the moisture content of the refuse ha~ <br />reached the level needed for rapid decomposition, a low permeability material will be placec <br /> <br />I over the refuse to minimize additional leachate generation. Ga~ generated during the <br /> accelerated decomposition process will either be exhausted and burned or recovered as a <br /> <br />useful product. <br /> <br />I The total capital cost of an gO-acre accel_ crated decomposition landfill is estimat:ed al <br /> $11J million, excluding the cost of engjneering~ land, equipment, and site improvements. The <br /> <br />I cos: of the double liner system is approximately $9 miJ~ion, the cos~ of the leachate <br /> coUection system is aproximately $1 million, and the cost of the leachate recycling system <br /> <br />I approximately $1 mLL[iono <br /> <br />I While the accelerated decomposition of shredded municipal refuse and the eventu~ <br /> use of the decomposed refuse as compost is a new concept in this area of the country, all <br /> <br />Ithese unit processes have been demonstrated to be technically possible. Secure Iandfild <br />have been constructed in aU parl~ of the country~ leachate is being recycled at variot <br /> <br />I sanitary landtrdl projects in or:her parts' of the country, and composting of' municipal refu., <br /> has been demonstrated. <br /> <br /> <br />
