Rochester, NY -- Rochester's General Motors plant says it is landfill-free -- meaning all of its waste is recycled, reused or converted to energy.
Environmental engineer Gail Finkelstein says the most challenging problem was finding a way to recover used machine oil filled with debris and metal bits. A centrifuge now allows the plant to separate the contents.
The plant is the 109th GM facility nationwide to achieve landfill-free status.
Plant manager Neil Evans says it didn't cost much to become "landfill-free" and waste recovery actually generates revenue for the plant.
