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.
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 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)".

Private interests subsequently invested significantly in an anaerobic digester, a facility used to convert food waste into biofuels, that could take in food diverted from landfills. But they had a ...
Energy: for example digesting feces and other organic waste to produce biogas; or producing combustible fuels. Other: other emerging excreta reuse options include producing protein feeds for livestock using black soldier fly larvae , recovering organic matter for use as building materials or in paper production.
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 ...
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 ...
