UNEP released a report calling for an increase metal recovery
13 United Nations Environment Programme released a report that a substantial increase in metal recovery can not only relieve the growing demand for resources caused by the pressure, also helps protect the environment. United Nations Environment Programme United Nations Headquarters in New York, issued the same day on the "society of metal stock", and "Metal Recovery" report. Report that in the past century, human production and life use of the growing number and variety of metals, metal stocks in today's society has become a huge "earth minerals." Yale University professor of industrial ecology Tuomasige Riddle in the day's news conference, said more and more metal, "floating to the ground", stored in buildings, ships, and even cell phones, computers. For example, in the United States, in the "above ground" of copper has reached 240 kg per capita. However, the recovery of most metals are very low. Reported that, steel, iron, copper, aluminum and tin and other metals in the global recovery between 25-75%, while in some developing countries, the recovery of these metals were lower. Lithium, neodymium, gallium, indium and other metal products used in high-tech nature of the stock in less expensive, but their recovery rate of only 1%. Reported that compared with the primary ore smelting, recycling metals can save more energy, thereby increasing metal recovery is not only conducive to improving the supply, but also create new employment opportunities and to extend the life of nature in the development of mineral deposits.
