Welcome to Sierra Energy

    It is Sierra Energy’s goal to make waste gasification globally attainable and profitable. Since 2004, we have been developing and optimizing our FastOx gasifier which converts waste and recovers energy, more economically and on a more appropriate scale than other conversion technologies. This is achieved by its scalable design derived from the blast furnace.

    Waste Conversion

    Can you think of a better use for post-recycled waste than transforming it into renewable energy? Yeah, we couldn’t either. Our FastOx gasifier is robust and flexible, capable of processing municipal solid waste (MSW), hazardous waste, construction and demolition waste, and much more.  Click to learn more about our FastOx gasifier.

    Energy in Waste

    Typically, the energy in waste is thrown out and sent to landfills, creating mountains of trash, emitting harmful gases and pollutants into our air, water, and soil. Our waste gasifier uses this energy source instead of letting it waste away. Additionally, FastOx gasifiers create an energy-dense syngas capable of producing renewable, transportation fuels. The application of our waste gasification technology will eliminate pollution created by landfills and help reduce our nation’s dependence on foreign oil and the depletion of the earth’s fossil fuel reserves.

    Common Misconceptions About Waste Gasification

    Misconception: Waste gasifiers burn trash.
    Gasification is a completely different process than burning and incineration. Chemical reactions happen at the molecular level causing matter to vaporize into gas, resulting in far fewer emissions and pollutants than burning.

    Misconception: Waste Gasification Reduces Recycling
    Community recycling programs are imperative for helping promote awareness about individual and global waste generation. Waste gasifiers and most conversion technologies supplement and improve these efforts. Additionally, waste gasifiers tend to operate more efficiently when these recyclable materials are already removed.


    Sierra Energy is proud to announce that it has been named as a Going Green Silicon Valley Top 200 company for the second year in a row.
