A big part of the recycling of electronic equipment is the recovery of metals such as gold. Usually the printed circuit boards and other components are shredded, sorted, and then separated. But ...

Scientists have figured out a way to recycle important metals trapped inside electrical waste. Using textiles, researchers from the Korea Institute of Science and Technology (KIST) have improved the ...

Preparation and physicochemical characteristics of the aminated polyacrylonitrile fibers (PANFs). Representative illustrations of PANF (a) before and after coupling reaction of various alkylamine ...

A team led by Cornell researchers has devised an innovative method to recover gold from electronic waste and repurpose it as a catalyst for converting carbon dioxide (CO 2) into organic compounds.

An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has developed a safer and more sustainable approach to extract and recover gold ...

At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool ...

Electronic waste (e-waste) refers to discarded electronic devices such as smartphones, laptops, televisions, and other consumer or industrial electronics that are no longer functional or needed. These ...

(Nanowerk Spotlight) Electronic waste poses one of the fastest growing waste challenges worldwide, with over 50 million tons generated annually. Yet hidden in obsolete devices lies substantial amounts ...

(Nanowerk News) Korea relies on imports for most of its metal resources, and in recent years, due to resource depletion and rising raw material prices, 'circular resources' that recycle waste metal ...
