According to the Global E-waste Monitor, a project backed by the United Nations Institute for Training and Research, people disposed of 53.6 million metric tonnes of e-waste in 2019 — a quantity that is expected to increase by nearly 40% by 2030

“This is an opportunity to stop thinking of it as waste,” says Clara Santato, a chemist specializing in electroactive materials at Polytechnique Montréal in Canada. But making electronics more sustainable will also require a more radical evolution of the industry as a whole, as well as the consumers who crave their products

Not everything can be readily recycled, but there are opportunities to create ‘green electronics’ that can be produced and disposed of in a more environmentally friendly way.

as of 2019, only around 17% of the world’s e-waste was being properly managed for recycling in the countries that generate it

In an initial demonstration, this method recovered more than 80% of the precious metals, such as palladium and silver, that were present in an e-waste sample4, while also enabling easy isolation of toxic compounds such as mercury and lead.

Standard building blocks such as silicon, iron and copper are typically joined by more exotic elements. These include highly conductive precious metals such as platinum and gold, as well as rare-earth elements such as neodymium, which possess unique magnetic and electrical properties.

Conventional circuit boards are built on fibreglass, which is non-biodegradable and typically laced with potentially toxic fire-retardant compounds. Martins’ group is working on paper-based boards that could offer an environmentally friendlier alternative.

recyclable or compostable electronics could become invaluable in devices intended for short-term use, or in narrow-purpose devices such as wearables or environmental sensors that don’t have to meet the same rigorous performance standards as the processors found in smartphones.

Planned obsolescence by manufacturers is part of the problem, but resolving this issue will also be a matter of public education and policies that boost civic-mindedness and environmental consciousness

The article recommends tighter regulations and corporate accountability as means to limit e-waste production and facilitate a cultural shift. E-waste production is set to increase rapidly and will see a 40% increase in quantity by 2030 unless checks are put in place. Creating green electronics has been discussed as an important step as manufacturers have been urged to use biodegradable components in their devices. The article further encourages businesses to promote circularity while highlighting that the responsibility also falls on consumers to adopt better practices. Public education is discussed as a critical tool to make populations aware while consumer electronics brands have been urged to make devices that are easy to disassemble and repair to increase longevity.
