There are basically two technological routes employed to achieve the energy use of waste: the direct flaring of waste (waste-to-energy) or combustion of the biogas produced from the decomposition of organic matter waste. There are about 1500 thermal plants world wide that burn waste to generate power or heat. The technology is expensive. The advantage is the processing of burned waste in about 12% of its original size in ashes.
In Brazil, energy use of waste has been possible by waste gas burning , also known as biogas. Simple burning methane, without any energy recovery, already provides an environmental benefit by transforming CH4 (methane) into CO2 (carbon dioxide).
In enterprise’s logics, the return of invested capital occurs in two ways: the issuance of carbon credits (when a UN certification measures the amount of methane flared and converts that number on paper with a market value to rich countries signatories of Kyoto Protocol which committed to reduce their emissions) and electricity salesIn a country that produces 198 000 tons of waste per day, can you imagine what this means in terms of energy?
