Abstract: The possible solutions to the problems related to the generated waste are to raise the prices of all goods so that they can offset the cost of treating the generated waste. Energy is one of the key elements in the idea of achieving sustainable development, especially when it comes from clean and easily accessible alternative sources, and waste can also be considered as such. The result from done survey show, a clear relationship is established between the carbon content of the initial material and the amount of oxygen and dry air required for combustion. Such connection was also confirmed in the sulphur dioxide content in the generated gases and the sulphur content of the initial material. Calculations show that the energy generated by burning 20,000 tons of material per year would result in energy savings from conventional sources needed to meet the needs of between 50,000 and 60,000 households.

Keywords: waste to energy; combustion; heating value; compost; RDF.
