Metal-lifespan analysis shows scale of waste

Freda Kreier in Nature:

A study looking at the economic lifetimes of 61 commercially used metals finds that more than half have a lifespan of less than 10 years. The research, published on 19 May in Nature Sustainability1, also shows that most of these metals end up being disposed of or lost in large quantities, rather than being recycled or reused.

Billions of tonnes of metal are mined each year, and metal production accounts for around 8% of all global greenhouse-gas emissions. So, recycling more metal could help to lower its environmental impacts, says co-author Christoph Helbig, an industrial ecologist at the University of Bayreuth in Germany.
