Ze-gen, Inc. was a renewable energy company developing advanced gasification technology to convert waste into synthesis gas. Founded in 2004, Ze-gen was a venture-backed company based in Boston, Massachusetts.
The company aimed to develop innovative technological solutions to reduce landfills and find beneficial use for waste material by converting waste to energy and nutrients, using advanced gasification.
Today Ze-gen appears to be defunct, and the company website was taken down in 2014.
The liquid metal gasification process begins with feed material entering the gasifier through a gas-tight airlock into a refractory-lined vessel containing liquid copper, which is held at about 2200 °F. Material entering into the liquid metal gasifier undergoes a series of thermo-chemical reactions, which are auto-thermal under stable operating conditions. Initially, pyrolysis occurs and volatiles are driven into the headspace of the gasifier. In the subsequent gasificati
