ZeroPoint Clean Technology is a company focused on renewable energy, specifically in the biomass power plant sector. The company's main service involves the construction of 2-12MW biomass power plants using leading biomass gasification technology, which converts woody biomass into high-quality synthesis gas and a stable form of sequestered carbon, known as biochar. This synthesis gas can replace oil or gas in engines, burners, and boilers, or be used to produce chemicals and liquid fuels. It was founded in 2006 and is based in Potsdam, New York.

ThermoChem Recovery International markets a gasification technology that aims to transform the pulp and paper industry into biorefineries which will not only produce paper, but also renewable energy in the form of green electric power and bio-based fuels and chemicals. TRI's gasification process converts cellulosic feedstocks (including wood chips, bark, forest residuals, agricultural waste and energy crops) into a synthesis gas ("syngas") which can be used to replace natural gas and fuel oil, and can be converted into biofuels and biochemicals. Additionally, per the company, TRI's technology is capable of recovering energy and chemicals from spent pulping liquors. TRI licenses its gasification technology, and aims to provide specialized equipment and engineering services to pulp and paper companies seeking to integrate TRI's process into their mill operations. TRI's proven technology currently is in commercial use at two mills in the U.S. and Canada.
