Within EU we already pay ~€3 for packages from China. And in Austria we will soon pay additional ~€2 for every delivered package. And 20% VAT.
Edit:
I am pretty sure at least some part of these already contribute towards recycling.
The goal here is likely not just to get more funding for recycling, but rather to use materials that can be recycled in the first place. Which you cannot achieve simply by charging businesses or consumers more.
