Gasification

Ze-Gen is another company using gasification to treat waste to get energy, but it's going after a more uniform waste stream: construction and demolition debris. The company has operated a demonstration facility in Massachusetts for more than a year and is seeking to scale up with an industrial company looking for a way to handle waste and produce heat and power on-site. Ze-Gen's gasifier operates at high temperatures, exposing material to heat in a bath of fluid metal.
