In a literally green technological advance, a team of researchers has found a way to replace the conventional printed circuit board (PCB) in electronic devices with a biodegradable alternative made out of tree leaves. Reported earlier this month in Science Advances, such “leaftronics” could help reduce the tens of millions of tons of electronic waste, or e-waste, humanity produces every year.

Five Sustainability Heroes New Electronics

 https://www.newelectronics.co.uk/content/features/five-sustainability-heroes  Conclusion Increasing sustainability is not just a single significant action, it can also be the combination of thousands of smaller changes that come together to form a greater net change. Through smarter component selection, deeper development and intelligent maintenance techniques, the electronics industry can work to reduce energy consumption, as well as lower raw material requirement through greater integration, maintenance schedules, and miniaturised designs. The sustainability ‘heroes’ highlighted here are a diverse range of products and solutions that can provide improvement through both significant innovation and through continued iterative improvement. Such components and systems can be used by engineers today to help improve the sustainability of future designs.

How ‘green chips’ are powering a sustainable future

 https://datacentrereview.com/2021/12/how-green-chips-are-powering-a-sustainable-future/ The link between the exponentially growing amount of data and the rising global temperature is direct and proven. Processing the ever-increasing amount of data requires immense energy — and the energy sector is responsible for  approximately 72%  of the world’s greenhouse emissions, making electricity the largest contributor to global warming, according to Greenpeace. Just like a smartphone gets hot when the battery or CPU overloads, a data centre gets hot as the amount of data traffic increases. Cooling it off requires substantial amounts of energy, which is why quite a few data centres are in cold regions like Finland, Sweden and Iceland, where cold air and seawater are in abundance. The future is looking challenging, with the amount of energy used to store and process human data forecast to surpass the amount of energy used to produce it.  IDC’s Global DataSphere  estimat...

Overcoming Changes and Challenges with Sourceability’s Datalynq

https://datalynq.com/post/how-to-manage-the-complexity-of-market-availability-for-electronic-components (Abril 2024). Datalynq is Sourceability’s market intelligence tool. It was recently integrated into Cadence’s OrCAD X Platform under Live BOM to provide design engineers with early warnings about risk-prone components in their designs. By replacing these components early with safer parts, product designs become more sustainable in the long run, preventing problems with advanced and mature nodes.
