![]() The mass burn process burns the waste virtually as it is received thereby eliminating the need to process the material prior to burning except for the removal of oversized items and obvious non-combustible metallic materials. Most modern waste incinerators now incorporate heat recovery systems and air-pollution control systems. Today the heat energy generated from the combustion process is used to turn water into steam, which is then used to power steam-turbine generators to produce electricity. The earliest waste combustion systems were simple incinerators which produced heat and carbon dioxide, along with a variety of other pollutants and had no energy recover capabilities. Municipal and household waste is directly combusted in large waste to energy incinerators as a fuel with minimal processing known as mass burning. ![]() The more common ways in which waste is converted in energy-Ĭombustion – This is by far the oldest, most common and well-proven thermal process using a wide variety of waste fuels. Waste that has been converted into biogas from both organic and inorganic wastes, or biological technologies, in which bacterial fermentation is used to digest organic wastes to yield fuel, converting the waste to fuel. Waste to energy processes include wastes that has been treated and made into a solid fuel for incineration to produce heat and steam. Energy can be derived from waste in a number of ways. These waste to energy processes includes thermal conversions such as combustion (incineration), pyrolysis, gasification, or biological treatments such as anaerobic digestion and fermentation, etc, and various combinations of the above.įor example, solid wastes can be converted into fuel pellets and along with gasified waste co-fired with fossil fuel coal in an existing conventional coal fired power station. Waste to energy technologies- Physically convert waste matter into more useful forms of fuel that can be used to supply energy. ![]() The category of waste to energy broadly describes any of a number of processes or technologies in which a useful byproduct (energy) is recovered from an otherwise unusable source. ![]() Traditionally the term “waste to energy” has generally referred to the practice of incineration of waste products either by burning the rubbish in the back yard or by large industrial incinerators to produce heat. Wastes generated from heavy industrial manufacturing activities, chemical and medical industries are typically classified as hazardous wastes and are generally not used to convert this type of waste to energy. Such waste materials typically originate from either the residential community as municipal solid waste or from commercial, light-industrial, and agricultural wastes. ![]()
