E-Waste: A Global Goldmine and Health Hazard

The worldwide explosion in electronic device adoption has created an equally incendiary waste problem, according to the United Nations University and the Global e-Sustainability Initiative. Manufacturing of various electronic devices uses about $21 billion worth of gold and silver annually; however, the UN says less than 15 percent of these precious metals are recovered. Discarding such volumes of e-waste has the potential to create health and environmental hazards. Other valuable metals -- copper, tin, cobalt, and palladium – could also be recovered. Plastics in e-waste is also problematic. The UN estimates if only half of the plastics in e-waste generated by the European Union alone were recycled, approximately 5 million kilowatt-hours of energy could be saved and CO2 emissions would be slashed by 2 million tons. “We need to recover rare elements to continue manufacturing IT products,” said Dr. Ruediger Kuehr, Executive Secretary of the Solving the E-Waste Problem (StEP) Initiative and head of the United Nations University StEP coordinating unit based in Bonn, Germany. “One day — likely sooner than later — people will look back on such costly inefficiencies and wonder how we could be so short- sighted and wasteful of natural resources.” These organizations recently hosted the GeSI and StEP E-Waste Academy, training for policymakers and small businesses held in Accra, Ghana.

UK Scientists Develop Easily Recyclable Printed Circuit Board


Scientists from the UK’s National Physical Laboratory have developed a printed circuit board that users can dismantle for recycling by simply dunking it in hot water. The research, designed to make electronic assemblies easier to recycle, included the design and test of unzippable polymeric layers. The materials can withstand the thermal demands of a device’s operation but also disassembles into constituent parts by immersion in hot water when the part is obsolete. The project was funded by the UK government’s Technology Strategy Board and conducted with In2tec and Gwent Electronic Materials scientists. (PhysOrg)(National Physical Laboratory)
