Sierra Energy's FastOx® gasification technology converts virtually any waste into clean, renewable energy and fuels without burning. Developed by Sierra Energy and supported by grant funding from the Department of Defense and the California Energy Commission, FastOx gasification uses oxygen and steam to heat waste to 4,000°F (2,200°C). At this temperature, all waste breaks down at the molecular level, converting organic material into an energy-dense syngas and allowing the recovery of inorganic material as either a non-leaching stone or molten metal. The technology, which is modular and can be scaled to large size, does not produce any process emissions and all outputs are saleable. The company’s first commercial-scale demonstration facility is located at U.S. Army Garrison Fort Hunter Liggett in Monterey County, California. One of FastOx gasification’s greatest advantages is a proven ability to handle nearly any type of waste, including municipal solid waste, plastics, medical waste, e-waste, tires, batteries, railroad ties, and even hazardous wastes. This feedstock flexibility, and the capacity to turn produced syngas into a variety of high-value end products, makes FastOx gasification extremely versatile and economically efficient to implement. Local developers configure the system to match local market needs. Since Sierra Energy’s FastOx gasifier is based on well-understood blast furnace technology, it is also robust, with long up-times and low maintenance requirements.
