As more and more companies are looking to project an earth-friendly image, many are proving that such practices can also make good business sense. A notable example, according to the group PERC, is General Motors which recently announced it has eight manufacturing plants that use no landfill space. At its Baltimore plant, GM now recycles 600 tons of steel each year that was previously designated as waste, but now is sent to its own foundries to be used for engine blocks, and other vehicle parts. With the automaker also giving away 360 tons of pallets for the wood to be reused, GM has reduced annual waste management costs from $32 million to just $8 million, and is showing that “good for the planet” can be “good for the bottom line.”
