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.

The question, however, is an open one, as European countries which recycle the most (up to 70%) also incinerate to avoid landfilling. [10] Incinerators have electric efficiencies of 14-28%. [9] In order to avoid losing the rest of the energy, it can be used for e.g. district heating (cogeneration).
A 2007 Department of Energy study found the potential for 135,000 megawatts of combined heat and power (which uses energy recovery) in the U.S., [8] and a Lawrence Berkley National Laboratory study identified about 64,000 megawatts that could be obtained from industrial waste energy, not counting CHP.

Recycled resources require less labor and energy to convert into new products, which reduces environmental pollution and production costs. Therefore, closed-loop recycling may be considered part of environmental sustainability programs. [8] One goal of closed-loop recycling is to reuse materials in an identical role as before recycling.
Waste heat from air conditioning can be reduced through the use of passive cooling building design and zero-energy methods like evaporative cooling and passive daytime radiative cooling, the latter of which sends waste heat directly to outer space through the infrared window.
Energy recovery, also called energy recycling or quaternary recycling, involves burning waste plastic in place of fossil fuels for energy production. [ 118 ] [ 4 ] It is included in the recycling data reported by many countries, [ 119 ] [ 120 ] although it is not considered recycling by the EU. [ 121 ]
