The path to zero waste.
Slag is safe for use in construction
The molten stone known as “slag”, produced during the gasification process which has a myriad of potential uses in the construction industry, or as high density filler, if demonstrated to be non-leaching. Sierra Energy’s slag has undergone extensive testing, including the U.S. EPA’s Toxicity Characteristic Leaching Procedure (“TCLP”), which has confirmed that Sierra Energy’s slag is non-leaching and environmentally safe to use!
These positive test results open yet more markets for Sierra Energy’s slag, creating even more benefits from the use of the FASTOX™ process, and allowing even further recycling and reduction in the amount of virgin construction materials consumed by our world.
