METHANE GENERATION POTENTIAL AND BIODEGRADABILITY OF MSW COMPONENTS

As an important parameter for estimation of methane generation from landfills, we measured ultimate methane yields (M0 VS) of various municipal solid waste (MSW) components, which were obtained by classifying bulk waste carried into S landfill in Korea. Food wastes exhibited the highest M0 VS of 420mL CH4/g VS. Misc. …
