Key Metals Not Recycled

July 11, 2011 at 7:36 pm Leave a comment

One of the most energy-intensive, and potentially environmentally harmful, activities required to sustain our high-tech civilization is mining. Although coal mining and petroleum drilling grab the headlines, mining for various metals is equally important. Metal recycling (collecting those old soda cans and obsolete computers, for example) can make a huge impact by making some mining unnecessary. And, unlike with paper or plastics recycling, metals recycling usually produces material that is every bit as good (if not better) than the originally mined ore.

Unfortunately, a new (May 2011) United Nations report indicates that world-wide metal recycling efforts are very inefficient. The report identified 60 different important metals and said that fewer than one-third of these were recycled at rates of 50% or better. Most of the metals just go into the trash. The original report is here. A short news article about the report (C&E News, May 30, p. 9) is here.
