Mahdokht Arshadi, a researcher from Islamic Republic Iran has recycled electronic waste using biological methods managing to recover gold and copper. “E-waste is a term for electronic products that have become unwanted, non-working or obsolete, and have essentially reached the end of their useful life and need to be recycled or buried,” said Arshadi.
The researcher stated that “we managed to recycle e-waste through a biological method exploiting two indigenous bacteria in order to extract gold and copper. Consisted of a two-step process on the basis of bio-leaching procedures, the new method is simple, inexpensive and environmentally friendly”. She further enumerated the benefits of the newly-developed biological method including being cost-effective, producing a high rate of value-added as well as preventing environmental problems.
