General Motors Co. is extending its efforts to divert waste from landfills.

The automaker, which already has achieved landfill-free status at 76 manufacturing locations, now says 10 nonmanufacturing sites also reuse, recycle or convert to energy all waste from normal operations.

“Our nonmanufacturing facilities see the importance of being waste-reduction leaders, and they know their customers value it as well,” said John Bradburn, manager of GM’s waste-reduction efforts. “Being landfill-free has become a point of pride for our people and we hope even more facilities achieve the goal this year.”

GM’s facilities, in total, recycled 92 percent of the waste they generated in 2010.
