We live in an era of mass overproduction. Offices, apartments, cars, ships, aeroplanes, mobile phones, laptops, batteries, televisions, furniture, air fryers, hot tubs, elevators and escalators. A countless multitude of objects that belong to the anthroposphere – a term for everything that people have made and how it all interacts with the planet.

Many of these products end up as waste, buried in landfill, incinerated or dumped – with catastrophic environmental consequences. At the same time, mining companies continue to pollute the planet, exploit local communities and produce huge CO2 emissions in the drive to make more products.

But what if there was a way to use what we already have, instead of mining for more raw materials? Could this alternative system reduce the need for ore, while avoiding the extractivist violence and exploitation that characterise the mining industry?
