Can Norway help us solve the plastic crisis, one bottle at a time?

A bottle deposit hub on the outskirts of Oslo has had a stream of high-level international visitors. Can its success be replicated worldwide?

Tens of thousands of brightly coloured plastic drinks bottles tumble from the back of a truck on to a conveyor belt before disappearing slowly inside a warehouse on the outskirts of Oslo.

As a workman picks up a few Coke bottles that have escaped, Kjell Olav Maldum looks on. "It is a system that works," he says as another truck rumbles past. "It could be used in the UK, I think lots of countries could learn from it."
