Quoted A circular economy for smart devices (green-alliance.org.uk)

This report shows how companies across the mobile electronics supply chain can adopt a circular economy model to make money out of old devices, attract new customers around the world, increase brand loyalty, and cut manufacturing costs and risks. Doing so would also help to cut electronic waste, carbon emissions and resource use.

The report seems quite business-focused.  The intended reader seems to be businesses?  The environmental and social benefits seem to be presented as a side benefit.
Quoted From Smart to Senseless: The Global Impact of 10 Years of Smartphones

Slowing the production cycle means making phones that last longer, which allows the resource and energy drain of each device to be spread over time. Extending lifespans is about designing more durable products, capable of being easily and inexpensively repaired or upgraded. It’s also about extending the lifespan of components, by harvesting parts from e-waste to reuse as spare parts or in new phones.

Design choices to extend product life include 1) material selection, i.e. whether the plastic or metal is non-virgin and is suitable for clean recycling, 2) accessible components, so that devices can be easily repaired and later disassembled, 3) availability of software updates, repair manuals, and spare parts.

Bookmarked A circular economy for smart devices (green-alliance.org.uk)

This report identifies how laptops, tablets and smartphones, which are up to five years old, can be profitably recovered and resold in the UK, US and India. It describes six business models that companies can use to adapt to consumer preferences for lower cost, longer-lasting electronics, and how reuse can bring the benefits of internet connected devices to new consumers in the developing world.

Manufacturers should measure their innovation not by fewer millimeters and more megapixels, but by designing devices to last, by making them easily repairable and upgradeable, and using components and materials that can safely be reused again and again to make new phones.
