The conversion of community-derived wastes to methane in a high-rate digester. La conversion des dechets solides municipaux en methane dans un digesteur a rendement eleve
The Institute of Gas Technology (IGT) has been operating a 4.5-m/sup 3/, anaerobic solids-concentrating digester at the Walt Disney World Resort Complex in Lake Buena Vista, Florida, since January 1984. This digester development work is part of a larger effort that provides effective community waste treatment and disposal options while recovering a valuable methane resources from these wastes. Excellent conversions to methane have been obtained in the digester during 4 years of uninterrupted operation. Data were collected on wastes from experimental municipal wastewater treatment applications, that is, water hyacinths were harvested from secondary wastewater treatment channels and combined with sludge from primary clarifiers to maximize potential methane recoveries in the digester; wastes from agricultural operations, that is, sorghum was selected as a candidate because it represents both a potential energy crop, as well as a waste resource if only portions of the plant are converted after grain production; and wastes from municipal waste collection. Municipal solids waste (MSW) from a commercial resource recovery center was selected. 3 refs., 4 figs., 5 tabs.
