Electronics industry turns to circular economy for resilience amid supply shortages

The electronics sector is confronting an awkward contradiction: vast quantities of discarded equipment are piling up even as factories struggle to secure essential parts. That tension has helped push the circular economy from an environmental slogan into a practical industrial strategy, especially in automation, where the ability to keep PLCs, drives and I/O modules in service can be just as valuable as buying the latest hardware.

In manufacturing, the appeal is straightforward...

. Refurbished components often come in significantly cheaper than new OEM replacements, and the savings can become substantial across a plant with multiple production lines. More importantly, circular practices can prevent so-called forced upgrades, where a missing module prompts the replacement of an entire machine. In periods of shortage, that can mean unnecessary capital spending, longer outages and more exposure to supply shocks.

The logic is not only financial. Much of an electronic component’s carbon burden is created before it ever reaches a factory floor, through mining, fabrication and assembly. Extending the operating life of equipment spreads that embedded impact across a longer period, reducing the emissions attributed to each year of use. That is one reason researchers and policy groups have increasingly linked circularity with resilience rather than treating it as a purely sustainability-led exercise.

The World Economic Forum has argued that manufacturers can strengthen supply chains by designing products and business models around durability, repairability and recyclability. Its broader message is that the move away from a throwaway model is not just about waste reduction; it is also about building systems that can adapt when resources tighten or suppliers fail. An OECD review published in 2025 made a similar case, saying reuse, repair, refurbishment, remanufacturing and recycling can all support both environmental goals and more robust supply chains.

Academic work has gone further, suggesting that circular readiness can directly improve resilience. A recent study in ScienceDirect found that Industry 5.0 approaches, combined with remanufacturing capabilities and circular strategies, can strengthen crisis preparedness and disaster recovery. In other words, the ability to recover, rework and reintroduce hardware is becoming part of operational continuity planning.

In practical terms, much depends on how assets are handled. At the board level, repairs such as capacitor replacement, firmware re-flashing and connector reseating can often be quicker and cheaper than sourcing a full replacement. Repair labs are increasingly using thermal imaging, X-ray inspection and micro-soldering to diagnose and restore older boards. Where damage is localised and parts are available, refurbishment can make clear economic sense. Replacement is usually the better option when board layers are delaminated or major integrated circuits have been permanently damaged.

The secondary market also has a larger role to play, but it requires discipline. Sourcing from surplus and independent suppliers can improve resilience, provided buyers insist on traceability, testing records and quality controls. The risk, as industry observers note, is that “used” stock may simply mean unverified stock. That is why testing standards matter: visual inspection, functional load testing, burn-in periods and clear documentation can make refurbished equipment more dependable than old inventory that has sat unused for years.

Preventive maintenance remains another pillar of the circular model. Better cabinet cooling, dust filtration, positive-pressure ventilation, timely replacement of memory batteries and routine burn-in checks for critical spares can all extend equipment life and reduce failure rates. These are not dramatic measures, but they are often the difference between a manageable maintenance cycle and an avoidable shutdown.

The wider policy and industrial context is also changing. As electronic waste grows and manufacturers face repeated supply disruptions, circular electronics is increasingly being framed as a resource strategy as much as an environmental one. The challenge now is less about proving the concept than operationalising it: building repair capability, managing obsolescence, and treating secondary inventory as a strategic asset rather than a last resort.

For plant managers and procurement teams, that means a more deliberate approach to spares, scrap and replacement decisions. For the industry as a whole, it suggests that the future will belong not simply to those with access to the newest silicon, but to those able to get the most value, and the most service life, out of what they already have.
