It looks as though Scotland's attempt has been scuppered by Westminster using the excuse that all schemes must be aligned in the UK. Why?
There are ten different schemes running in Europe - all slightly different. With the exception of Croatia they are all in Germanic or Nordic countries with shared borders. If they can run independently of each other then why can't the same be true for the UK.
The return rates run from 82% in Estonia to 97% in Norway.
It is hard to get figures for the UK because we do not calculate waste streams in any meaningful way, but as an overall rate our recycling is below 50%, and a lot of that is not "recycled" it becomes what is known as Incinerator Bottom Ash because we burn a lot of our "recycling".
So much for net-zero and helping the environment eh?
