Sustainable Engineering could not let Circular Electronics Day pass without a quick summary of our pillars of sustainable design.
Embodied carbon
Your bill-of-materials offers opportunities to reduce embodied carbon through careful design and technology choice.
Durability
Target R&D at durability weak links and use them as opportunities.
Functional efficiency
Keep pace with electronics innovations. Most, will exhibit reduced energy consumption.
Minimisation
Use new CAD technology to optimise designs for minimum material use. Consider additive manufacturing.
Weight reduction
Weight reduction improves dynamic response and reduces energy consumption. Choose lightweight components/materials.
Integration
‘Integrated circuit’ says it all. Where possible adopt integrated solutions, such as modules, which can offer multiple sustainability benefits.
Reliability
Improving reliability reduces maintenance. Keep an eye on components' mean-time-between-failure data.
Recycled content
From reclaiming semiconductor die to switching to recycled engineering polymers, explore recycled material technologies.
Non-hazardous materials
Keep up to date on hazardous material compliance such as PFAS. It benefits your company, customers and the environment.
Design for assembly
Reduce the energy and resources required to manufacture products by adopting best practice design for assembly techniques.
Packaging
Avoid or minimise. If packaging is required, optimise materials that are part of an existing, functioning and accepted recycling infrastructure.
Transport
It’s common for electronic products to travel long distances. Plan ahead and let your products travel slowly by sea.
Design for disassembly
Make it easy to disassemble products for maintenance, repair and end-of-life.
Maintainability
Make products easy to maintain, thus improving durability and reducing energy and resource use.
Repairability
If something does fail, make it easy to repair. Can the failed part be repaired, reused, upcycled or, if necessary, easily recycled.
Upgradeability
Maximise durability via upgradeability. Identify the components that impact durability and modularise them.
Reuse
When a product has reached its useful life in its original application, could it be down cycled and used again?
Recyclability
How easy is it to recycle a product’s constituent parts? The materials will have value provided they can be extracted and repurposed.
Let’s conclude with a classic example of a new technology contributing to multiple sustainability pillars in the form of Jiva Materials Ltd’ Soluboard, a world first in low carbon, recyclable and biodegradable PCB substrates. It’s UL approved, PTH compatible and under evaluation by some of the world’s largest OEMs.
Proof the above can and is being done.
