UN: Treated Waste Could be ‘Gold Mine’ | Source: Environmental Leader – Oct 10 2013
Recycling and waste treatment can be a “gold mine,” perhaps literally, according to a UN report that finds treated waste can be put to profitable use.
For example, 1 metric ton of electrical and electronic wastecontains as much gold as 5 to 15 metric tons of typical gold ore, and amounts of copper, aluminum and rare metals that exceed by many times the levels found in typical ores. As a result, printed circuit boards are probably the “richest ore stream you’re ever going to find,” according to the Guidelines for National Waste Management Strategies: Moving from Challenges to Opportunities.
Many waste products can be reused and, if waste is separated at source, the uncontaminated organic fraction can be composted or digested anaerobically, the report says.
