The proliferation of electronic devices has contributed to the accelerated surge of greenhouse gas (GHG) emissions in e-waste, according to a new study in Circular Economy. E-waste GHG emissions rose 53 percent between 2014 and 2020. Researchers anticipate e-waste will annually generate 852 million metric tons of CO2 compounds by 2030.

According to the United Nations, less than a quarter of all U.S. electronic waste gets recycled. In 2021 alone, global e-waste surged at 57.5 million tons, and only 17.4% of that was recycled.
Some experts predict that our e-waste problem will only get worse over time, because most electronics on the market today are designed for portability, not recyclability. Tablets and readers, for example, are assembled by gluing circuits, chips, and hard drives to thin layers of plastic, which must be melted to extract precious metals like copper and gold. Burning plastic releases toxic gases into the atmosphere, and electronics wasting away in landfill often contain harmful materials like mercury, lead, and beryllium.
But now, a team of researchers from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have developed a potential solution: a fully recyclable and biodegradable printed circuit. The researchers, who reported the new device in the journal Advanced Materials, say that the advance could divert wearable devices and other flexible electronics from landfill, and mitigate the health and environmental hazards posed by heavy metal waste.

Quadloop, a Nigerian based company, has found a way to turn electronic waste into solar lanterns and other products which will have a lower impact on the environment.
Dozie Igweilo, founder of Quadloop, told Reuters he came up with the idea after discovering a market for affordable, locally produced electrical goods, for which components were not available in the country.

The REMADE Institute, a 154-member public-private partnership established by the United States Department of Energy (DOE) with an initial investment of $140 million, today announced a new technology license involving a technological innovation capable of recovering precious metals from used electronics more easily and cost-effectively.
The innovation, developed with REMADE support, is part of a research and development project first funded by the Institute in 2020. The R&D project, “Low-Concentration Metal Recovery from Complex Streams Using Gas-Assisted Microflow Solvent Extraction (GAME),” is still in progress and is led by Wencai Zhang, Ph.D., an assistant professor in the Department of Mining and Minerals Engineering at Virginia Tech’s College of Engineering, and Aaron Noble, Ph.D., an associate professor in the same department. Phinix, LLC, is the industry partner on the project. REMADE’s tech team oversees the project, ensuring it meets the Institute’s and DOE’s technological milestones.
