Abstract

Publisher Summary This chapter describes the use of landfill gas fuel and ecological problems. Solid municipal wastes are fairly often not disposed of immediately. They are mainly landfilled. Stocks of them grow permanently and one is threatened with a time bomb. Up to now, there has been a lack of successful ways to complete degradation, destroying or utilization of all the ingredients of the municipal waste. The principal ways of dealing with municipal waste are: recycling, incineration, composting, and landfilling. The biodegradation methods are used as aerobic composting in heated and aerated reactors, anaerobic biodecomposition of hydrocarbons in dump conditions. The main product of the anaerobic process landfill gas contains methane and carbon dioxide. One of the reasons why landfills are a problem is because of the generation of landfill gas. Landfill gas is the fuel received from solid waste in a very simple and economic way in a natural reactor - landfill. Combustion and utilization of landfill gas is, as a rule, less hazardous than solid waste itself. In the bioprocess, it is transformed into gas with 40+60 % of refuses hydrocarbons.
