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.
The Alpena biorefinery plant in the USA. A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals). The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)".

Harvest Power's services are cited as a model for a circular economy of converting food waste into energy and nutrient-rich soil products. [11] Food waste specifically has been identified by cities and businesses as an untapped resource that – if diverted from landfills – can be used for clean energy and soil revitalization.
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 ...
BRI Energy, LLC [1] is a company whose pilot plant in Fayetteville, Arkansas is currently using synthesis gas fermentation to convert a variety of waste into ethanol. After gasification, anaerobic bacteria (Clostridium ljungdahlii) are used to convert the syngas (CO, CO 2, and H 2) into ethanol. The heat generated by gasification is also used ...
The funding will go towards the development of anaerobic digesters across the U.S. to turn wasted food into renewable energy. [16] In April 2023, the company announced the groundbreaking on its Turlock, California food waste to renewable energy facility. Once fully operational in 2024, the facility should process 100,000 tons of wasted food ...

Transforming food waste to either food products, feed products, or converting it to or extracting food or feed ingredients is termed as food waste valorisation. Valorisation of food waste offers an economical and environmental opportunity, which can reduce the problems of its conventional disposal. Food wastes have been demonstrated to be ...
