Is Recycling Worth the Effort?

The value of recycling depends on the material in question and whether all hidden costs and benefits go into the analysis. David Biello reports. January 28, 2015 | |

At , discarded metal and plastic gets bulldozed into a large mound. The stuff is then scooped onto the first of a series of rising conveyor belts, from which the trash is sorted through means both mechanical and manual.All that effort produces a variety of salable products, from metals to paper fibers. But ?In the case of an aluminum can the answer is an unqualified yes. Such a be recycled endlessly with no loss of quality. And recycling a can uses less than five percent of the energy that it takes to refine bauxite ore into fresh aluminum. when it comes to all metals, though we're better at recycling aluminum than say . In principle it could work for plastic too. But because plastic is made from petrochemicals, low oil prices can make it cheaper to just dump old plastic and manufacture new. And plastics degrade as they're recycled, as does paper.That said, a simple cost-benefit analysis does not correctly measure the environmental costs of dumping plastics or cutting down more trees for paper products. The EPA suggests that reduces the same amount of greenhouse gas pollution as taking more than 38 million cars off the road.The sound of recycling may prove music to the ears of future generations.—David Biello
