2. Waste-to-energy - Wikipedia

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

   Incineration, the combustion of organic material such as waste with energy recovery, is the most common WtE implementation. All new WtE plants in OECD countries incinerating waste (residual MSW, commercial, industrial or RDF) must meet strict emission standards, including those on nitrogen oxides (NO x), sulphur dioxide (SO 2), heavy metals and dioxins.

3. Plasma gasification - Wikipedia

   en.wikipedia.org/wiki/Plasma_gasification

   Plasma gasification is a thermal process that converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide. A plasma torch powered by an electric arc ionizes gas and transforms organic matter into syngas, producing slag [1] [2] [3] as a byproduct. It is used commercially as a form of waste ...

4. 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 .

5. Plasma gasification commercialization - Wikipedia

   en.wikipedia.org/wiki/Plasma_gasification...

   Plasma gasification is in commercial use as a waste-to-energy system that converts municipal solid waste, tires, hazardous waste, and sewage sludge into synthesis gas containing hydrogen and carbon monoxide that can be used to generate power. Municipal-scale waste disposal plasma arc facilities have been in operation in Japan and China since 2002.

6. Landfill gas utilization - Wikipedia

   en.wikipedia.org/wiki/Landfill_Gas_Utilization

   Landfill gas is cheaper than natural gas and holds about half the heating value at 16,785 – 20,495 kJ/m3 (450 – 550 Btu/ft3) as compared to 35,406 kJ/m3 (950 Btu/ft3) of natural gas. [13] Boilers, dryers, and kilns are used often because they maximize use of the gas, limited treatment is needed, and the gas can be mixed with other fuels.

7. 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.
