One of the big questions at the moment is how to cut the amount of plastic we use and throw away - and the UK is looking to Norway for the answer.
The UK government has a team in Norway to find out more about their bottle return scheme, which they use to recycle plastic bottles.
Some people there call it a 'reverse vending machine'. But how does it work?
Well, in Norway, you have to pay a bit extra to buy things in plastic bottles.
Then, once you've finished with the bottle, you put it into a special vending machine.
The machine then gives you a voucher for money back.
It seems to be working - as Norway recycles 97% of all its plastic bottles.
Scotland has already announced it wants to bring a scheme like this in in, and the rest if the UK is investigating.
