General Motors says by the end of 2010, half of its major global manufacturing operations will be land-fill free. The facilities plan to achieve that goal when all production waste or garbage is recycled or reused. So far, the company says 33 of its operations recently reached that status for a total of 43. At the landfill-free plants, more than 96% of waste materials are recycled or reused and 3% of that is converted to energy at waste-to-energy plants.

This will, in the long run, help the company’s bottom line. GM says as a result of its global recycling efforts, recycled metal scraps are approaching $1 billion in annual revenue. In North America alone, selling off its recycled cardboard, wood, oil, plastic and other materials added $16 million in revenue. GM has approximately 160 manufacturing facilities globally. It plans to make 80 of them landfill-free.
