Last year demonstrated how closed loop recycling can and does work in the real world. GM removed and replaced 475,000 square feet of roof at its Customer Care and Aftersale building in Lansing Michigan. Approximately 1,000,000 feet of recycled roof membrane was replaced and all the old roofing  was shipped off to be recycled into roofing material once again and in the end, diverted about 120 tons of material away from landfills. The new roof is white and reflects the suns rays, thus reducing the heat flow and saving on Air Conditioning costs. GM currently has 74 plants that do not send any waste to landfills.
