In this study we have assessed the ecological map of the Leningrad Oblast' and reviewed the existing normative documents. It is shown, that the ratio of processed wastes does not exceed 5–10 % of the total material amount, which is a low degree of municipal solid waste (MSW) recycling. We have established that using MSW as a fuel for thermal and electrical energy production helps save traditional fuel types, as well as reduces greenhouse gas emission. We have found that waste gasification is the most perspective method for thermal utilization. Aspens Plus software was used to perform gasification unit parameter modeling. The total efficiency of thermal and electrical energy production was 70,5 %.
