Maximising the lifetime value of components to reduce E-waste
(E&O) component inventory that eventually ends up being dumped. E&O stock refers to components that are surplus to requirements, typically caused by inaccurate demand forecasting or design changes. With so few REEs recovered from
electronics, the demand for raw resource extraction increases. For electronic manufacturers, preventing the unnecessary disposal of surplus components has a large role to play.

lectronic waste (e-waste) can contain toxic substances, such as cadmium, mercury, lead, and brominated fl ame retardants (BFRs). T ese materials can harm both
the environment and human health. Toxins may contaminate soil and water sources, particularly in parts of the world where unregulated recycling and dumping occur, putting people at risk. A key strategy to reduce e-waste and its impact is to extend the lifespan of materials. T is involves using components and rare earth elements (REEs) for as long as possible before proper disposal.
Current e-waste trends E-waste is a global problem, and its severity is quickly growing. Whether a consumer device, such as a tablet or television, or standalone components that go into manufacturing such technology, e-waste is one of the fastest- growing solid waste streams. In fact, 62 million tonnes were created in 2022. T is number is anticipated to rise by 32 per cent to 82 million tonnes by 2030. T e key drivers behind this increase include
the growing demand for consumer electronics, a replacement mentality, and the rapid pace of technological advancement, all of which shorten product lifecycles. Frequent design pivots may lead to the rapid accumulation of excess and obsolete

The average lifespan of a component When considering ways to extend the lifetime value of components, one must fi rst understand the typical lifespan—or ‘shelf life’— of a component. How long a component lasts generally depends on the type of part and how it is looked aſt er. When handled and stored correctly, semiconductors can last over fi ſt een years
in some cases, while capacitors, due to their sensitivity to moisture, may last only around ten years. Proper storage and handling ensure parts remain usable in the supply chain for as long as possible, preventing needless early scrapping or disposal. Temperature can damage components,
so storing them in a temperature-controlled environment is crucial. Electrostatic discharge can degrade parts, meaning grounding equipment and an anti-static environment are vital. Moisture build-up can cause ‘popcorning’ when devices heat up during soldering. T is is when a part literally pops, and it is why adhering to MSL guidelines and packaging is essential. If components are looked aſt er and remain
pristine, companies can implement strategies to put them to use long into their shelf life and prevent e-waste.
