reuse

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.”

But reusing and heating it too often - as is often the case in Honduras, where there is a huge black market for used cooking oil - can create compounds which are bad for consumers' health.

Scott Butler, executive director of Material Focus, an independent not-for-profit organisation, said that he was still concerned that vapes are still difficult to recycle and reuse.
