On May 9, the Environmental Protection Agency sent a letter to Vexor Technology Inc., saying the company’s composite material that can be burned in the place of coal can be considered a non-waste fuel rather than a solid waste. The material is comprised of cardboard, oleochemcials, paper, plastics, soy based inks; production of the composite removes noncombustible inorganic materials and metals. In August 2012, the agency determined that a feedstock component of the fuel can be treated as non-waste; the feedstock consists of fibers and plastics from commercial, industrial, and municipal solid wastes. In March, Vexor Technology asked the EPA to review the entire fuel.
