  2. Waste heat - Wikipedia

    en.wikipedia.org/wiki/Waste_heat

    For example, global forcing from waste heat in 2005 was 0.028 W/m 2, but was +0.39 and +0.68 W/m 2 for the continental United States and western Europe, respectively. [21] Although waste heat has been shown to have influence on regional climates, [22] climate forcing from waste heat is not normally calculated in state-of-the-art global climate ...

  3. Waste heat recovery unit - Wikipedia

    en.wikipedia.org/wiki/Waste_heat_recovery_unit

    The heat pipe is mainly used in space, process or air heating, in waste heat from a process is being transferred to the surrounding due to its transfer mechanism. Thermal wheel or rotary heat exchanger: consists of a circular honeycomb matrix of heat absorbing material, which is slowly rotated within the supply and exhaust air streams of an air ...

  4. Waste treatment - Wikipedia

    en.wikipedia.org/wiki/Waste_treatment

    Waste treatment refers to the activities required to ensure that waste has the least practicable impact on the environment. In many countries various forms of waste ...

  5. Thermal treatment - Wikipedia

    en.wikipedia.org/wiki/Thermal_treatment

    Thermal treatment is any waste treatment technology that involves high temperatures in the processing of the waste feedstock. Commonly this involves the combustion of waste materials. [1] Systems that are generally considered to be thermal treatment include: Cement kiln; Gasification; Incineration; Mechanical heat treatment; Pyrolysis; Thermal ...

  6. Energy recycling - Wikipedia

    en.wikipedia.org/wiki/Energy_recycling

    Energy recycling is the energy recovery process of using energy that would normally be wasted, usually by converting it into electricity or thermal energy.Undertaken at manufacturing facilities, power plants, and large institutions such as hospitals and universities, it significantly increases efficiency, thereby reducing energy costs and greenhouse gas pollution simultaneously.

  7. Waste-to-energy - Wikipedia

    en.wikipedia.org/wiki/Waste-to-energy

    Incineration generally entails burning waste (residual MSW, commercial, industrial and RDF) to boil water which powers steam generators that generate electric energy and heat to be used in homes, businesses, institutions and industries. One problem associated is the potential for pollutants to enter the atmosphere with the flue gases from the ...

  8. Water heat recycling - Wikipedia

    en.wikipedia.org/wiki/Water_heat_recycling

    Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...

  9. Waste management - Wikipedia

    en.wikipedia.org/wiki/Waste_management

    Waste-to-energy (WtE) or energy-from-waste (EfW) are broad terms for facilities that burn waste in a furnace or boiler to generate heat, steam, or electricity. Combustion in an incinerator is not always perfect and there have been concerns about pollutants in gaseous emissions from incinerator stacks.
