2. Waste-to-energy - Wikipedia

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

   Waste-to-energy (WtE) or energy-from-waste (EfW) refers to a series of processes designed to convert waste materials into usable forms of energy, typically electricity or heat. As a form of energy recovery, WtE plays a crucial role in both waste management and sustainable energy production by reducing the volume of waste in landfills and ...

3. Refuse-derived fuel - Wikipedia

   en.wikipedia.org/wiki/Refuse-derived_fuel

   Refuse-derived fuels are used in a wide range of specialized waste to energy facilities, which are using processed refuse-derived fuels with lower calorific values of 8-14MJ/kg in grain sizes of up to 500 mm to produce electricity and thermal energy (heat/steam) for district heating systems or industrial uses.

5. Sustainable energy - Wikipedia

   en.wikipedia.org/wiki/Sustainable_energy

   Energy storage helps overcome barriers to intermittent renewable energy and is an important aspect of a sustainable energy system. [154] The most commonly used and available storage method is pumped-storage hydroelectricity , which requires locations with large differences in height and access to water. [ 154 ]

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 management - Wikipedia

   en.wikipedia.org/wiki/Waste_management

   Using energy recovery to convert non-recyclable waste materials into electricity and heat, generates a renewable energy source and can reduce carbon emissions by offsetting the need for energy from fossil sources as well as reduce methane generation from landfills. [51] Globally, waste-to-energy accounts for 16% of waste management. [52]

8. Waste-to-energy plant - Wikipedia

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

   The typical plant with a capacity of 400 GWh energy production annually costs about 440 million dollars to build. Waste-to-energy plants may have a significant cost advantage over traditional power options, as the waste-to-energy operator may receive revenue for receiving waste as an alternative to the cost of disposing of waste in a landfill, typically referred to as a "tipping fee" per ton ...

9. Biogas - Wikipedia

   en.wikipedia.org/wiki/Biogas

   Biogas is a gaseous renewable energy source [1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor.
