#greentech Low metal recycling threatens green economy: UN report

Too much metal is being thrown away when it could be recycled, wasting an opportunity to save energy and risking shortages in materials used for new green technologies, a UN report warned Thursday. In a landmark study, the first to outline the extent to which metals are collected, the UN Environment Programme (UNEP) found that less than one third of about 60 metals studied are recycled to any significant degree. This is frustrating because recycling reduces the need for energy-intensive mining -- the report says extraction alone currently accounts for seven percent of the world's energy consumption. "In theory, metals can be used over and over again, minimising the need to mine and process virgin materials and thus saving substantial amounts of energy and water while minimising environmental degradation," said Achim Steiner, UN Under-Secretary General and UNEP executive di...
