Plasma gasification technology has been widely recognized as the future of waste treatment and conversion into reusable energy. Its advantages range from energy efficiency, reduced pollutant production, reduced greenhouse gases emission, conversion of waste products into recyclable materials, elimination of landfill necessity and so on.
You can read more about the technology here in a white paper from the Gasification Technology Council of the US, and its advantages in application presented in a 2012 symposium by Louis Circeo and Luciano Bardari. The Westinghouse Plasma Corporation of Canada also presents its current plasma projects in the UK, China and India.
