Owens Corning Building Achieves Green Seal Certification

Award Demonstrates Company’s Breadth of Green Practices

TOLEDO, Ohio,April 1 /PRNewswire-FirstCall/ — Owens Corning, a world leader in building materials and glass fiber reinforcements, today announced that a building at the company’s science and technology (S&T) center in Granville, Ohio, has met the Green Seal environmental standard for cleaning services. This is only the second building in the state of Ohio to achieve the Green Seal certification. Green Seal is an independent, non-profit group that safeguards the environment and promotes environmentally friendly products and services.

The Granville facilities team encouraged its cleaning service, ServiceMaster Facility Services by George, to meet the Green Seal standard, and worked closely with them to ensure the certification was met. As a result, all chemicals used to clean the building are environmentally friendly, and are automatically mixed in proper proportions to avoid using excess chemicals. In addition, chemicals are stored away from the main work space and all cleaning products are certified as sustainable. ServiceMaster also added floor and scraping mats near the doors to prevent dirt and dust from entering the building.

“This achievement proves we’re doing things right to provide a cleaner atmosphere for people in the building and for the Granville community at large,” said Vince Brown, Granville site operations leader.

Currently, other buildings on the Granville S&T site use similar green cleaning practices. Owens Corning’s goal is to have each S&T building meet the Green Seal standard by the end of this year.

Green Seal evaluates products and services through a full range of phases, beginning with material extraction, continuing with manufacturing and use and ending with recycling and disposal. Products only become Green Seal certified after rigorous testing and evaluation, including on-site plant visits.
