Waste Fuel
Energy Recovery.
Waste-to-energy (WtE) is an effective process of generating energy in the form of heat and/or electricity from the primary treatment of waste, or the processing of waste into a fuel source.
Most WtE processes generate electricity and/or heat directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels.
Incineration, the combustion of organic material such as waste with energy recovery, is the most common WtE implementation.
Bet Systems, like other modern WtE plants incinerating waste, legally meet strict emission standards, including those on nitrogen oxides (NOx), sulphur dioxide (SO2), heavy metals and dioxins. Hence, modern incineration plants are vastly different from old types, some of which neither recovered energy nor materials. Modern incinerators reduce the volume of the original waste by 95-96 percent, depending upon composition and degree of recovery of materials or minerals in the remaining ash.
Wood waste fuel, such as ground, shred, hammer-milled and or screened wood waste, is a prime fuel for the BET System which can efficiently dispose of contaminated wood waste without exceeding allowable emission standards. The intense combustion heat and sustained temperature effectively scrub contaminates and combust the harmful gases while completing an efficient WtE process.
Municipal Solid Waste (MSW) which represents your basic household waste is, to a large extent, of biological origin. (e.g. paper, cardboard, wood, cloth, food scraps) Consequently, this energy is often recognised as renewable energy according to the waste input.
MSW contains approximately the same mass fraction of carbon as CO2 itself (27%), so treatment of 1 metric ton of MSW produce approximately 1 metric ton of CO2. In the event that the waste was landfilled, 1 metric ton of MSW would produce approximately 62 cubic metres (2,200 cu ft) methane via the anaerobic decomposition of the biodegradable part of the waste. This amount of methane has more than twice the global warming potential than the 1 metric ton of CO2, which would have been produced by combustion.
Such considerations are the main reason why several countries administrate WtE of the biomass part of waste as renewable energy.
Recognizing nearly all biodegradable waste has biological origin, it is biomass. This material has been formed by plants using atmospheric CO2 typically within the last growing season. If these plants are regrown, the CO2 emitted from their combustion will be taken out from the atmosphere once more.
