Printing with sustainable materials to reduce e-waste

It is reported that global e-waste reached 96 billion kilograms in 2022 and is projected to hit 120 billion kilograms by 2030 at the current rate [1]. Green electronics aim to mitigate these impacts by designing devices using sustainable materials, efficient manufacturing processes, and end-of-life recyclability.

Green electronics are made with recycled, renewable, and low- or non-toxic functional materials. Their design emphasizes low-energy, often additive, manufacturing processes as well as component and material recovery [2]. Applications include energy-efficient consumer electronics, solar panels, medical sensors, and sustainable computing chips.

Frequently asked questions

While both are environmentally friendly electronics, green electronics refers to designing devices with low-impact materials (recycled, bio-based, non‑toxic), energy-efficient, additive manufacturing, and recyclability throughout their lifecycle. In contrast, biodegradable electronics specifically focus on devices that physically degrade into harmless byproducts after use, often for temporary applications.
Policies, like the European Union’s WEEE and RoHS directives, and certifications, such as EPEAT and TCO Certified, set criteria for recyclable design, low toxicity, durability, and energy efficiency. Extended Producer Responsibility (EPR) schemes further incentivize manufacturers to ensure end-of-life handling. In the U.S., EPA-endorsed R2/e‑Stewards recycling standards also promote responsible end-of-life management.
