An analysis of sorted biodegradable municipal waste composition was car-ried out. By repeated measurements of samples weighing more than 200 kg (the total amount of analyzed waste was 2098 kg) it was found that the undesirable impurities rate of sorted waste varies from 1 to 9% of weight (from 1 to 11.5% of volume). It is operationally difficult to separate biodegradable matter from non-biodegradable materials. If the quality of waste sorting does not increase, there will be possible just landfilling of sorted waste. It is consider on Biopas company workers whether it is possible and appropriate the energy utilization of sorted waste.
