Waste to energy: African opportunities | Ashurst

What Is WTE?The African PerspectiveCurrent State of The MarketKey Economic DriversOther Revenue StreamsWaste Volume RiskIdentifying OpportunitiesRecent WTE DevelopmentsIn very general terms, waste to energy facilities (or, as they are also known, energy from waste (EfW) facilities) create energy in the form of electricity and/or heat from the treatment of waste products. This is usually done by “thermally treating” (or incinerating) the waste. Most WtE processes produce electricity or heat directly through combustion. Alternatively, they might produce a combustible fuel such as methane or methanol from the treatment of a waste product. In addition to incineration, thermal treatment plants may instead involve gasification (producing a combustible gas) or pyrolysis (producing other products). Non-thermal technologies include anaerobic digestion, which is ideal for treatment of vegetable matter, food waste and animal by-products, typically producing a biogas, or mechanical biological treatment (MBT), which is used primarily for dry recyclable products and solid waste. Waste to energy plants have been used to treat and dispose of a number of waste pro...Get price
