Dow Corning to use plasma-based waste recycling system

Integrated Environmental Technologies, LLC (IET) announced contracts with Dow Corning Corporation and Veolia Environmental Services for the nation’s first plasma-based gasification process to recycle hazardous waste.

IET will install its patented Plasma Enhanced Melter™ (PEM) technology at Dow Corning’s plant in Midland, Michigan. The PEM facility will be operated by Veolia.

“Dow Corning has taken a major step in adopting this technology to convert its waste into products needed in its chemical manufacturing process,” said IET chief executive officer Jeff Surma.

Dow Corning’s facility will use IET’s PEM technology to transform hazardous chlorinated organic liquids produced at Dow Corning’s plant into aqueous hydrochloric acid (HCl) and clean synthesis gas (syngas). These products will be provided back to Dow Corning for its use to replace raw materials that it would otherwise purchase. The project will remove the need for off-site transportation and incineration of hazardous waste.

IET’s plant will convert more than 6,600 tons per year of liquid hazardous waste and produce 12 million pounds per year of HCl and 10.5 million BTU per hour of syngas. Design and procurement of the facility began in the summer of 2007 and it is expected to be online in mid 2008.
