Every week I receive at least one query asking me for pointers on finding statistics regarding how much China recycles on an annual basis. And, for the most part, my answer is the same: check Google, or check the trade publications. For example, a simple google search will reveal that China generated and recycled around 90 million metric tons of iron and steel scrap in 2010 – a volume greater than the steel produced in all but two countries (China and Japan). And if you’re lucky enough to have a subscription to Scrap Magazine, or Recycling International, you would’ve learned, in the Jan/Feb issues of both magazines, respectively, that China generated and recycled 2.32 million metric tons of its own – not imported! – aluminum in 2009 – a volume greater than the total steel manufactured in all but two countries (China and Russia). Below, an image taken at a large-scale, highly efficient aluminum scrap processing operation in South China (by me).
So one would reason, I think, that if an organization – say, the United Nations Environmental Programme – were interested in conducting a study to determine the worldwide recycling rates of all of the metals on the periodic table, that organization would want to get some Chinese experts – industry, government, trade associations – in on the preparation. And that’s precisely what the United Nations Environment Programme claimed to do when, two weeks ago, it released a study claiming to show global rates of recycling for metals. The report is downloadable, and it includes this very simple explanation of its methodology: Continue reading
