At GM, waste is viewed not as something to be thrown away, but as a resource out of place. By finding new uses for that waste — or selling it to someone who can — GM diverted 2.5 million tons of waste from landfills in 2011.
Worldwide, 90% of G's manufacturing waste is reused or recycled. This is apparently more than any other manufacturer. And it's not the sort of high-energy recycling where steel offcuts are melted back down for new steel, but instead a story is told of large flat steel offcuts being sold to local fabricator who cuts smaller bits from them.
