reused

The Scottish government points to a range of initiatives it has launched in recent years to tackle household waste and create a more "circular" economy, where material are reused over and over.

Apple is concerned that when devices are stolen, rather than being reused elsewhere they are instead being chopped up into component parts - like screens, processors and batteries - which can then be sold on for repairs.

Since this story starts centuries after the original inhabitants enter the bunker, she says, “Everything within the silo is essentially, when we come to it, reused, recycled and quite a bespoke make.”

These minerals and the lithium could - if recovered - be reused for green technologies such as electric car batteries or in wind turbines.

Theoretically such programs, which have been adopted in other states, including Washington, Oregon and Colorado, spur technological innovation and potentially create circular economies — where products are designed to be reused, recycled or composted.
