This technology converts waste into energy through an efficient gasification process. The FastOx gasifier uses a simple, proven design to convert a wide variety of waste streams into syngas, inert stone, and recovered metals on a large scale. By injecting oxygen and steam into the bottom of the gasifier, it produces an energy-dense syngas. This gasification technology is also uniquely scalable, able to process from 5 to 30,000 tons of waste per day in a single unit.
