I have no good solutions for plastic. We have a lot of plastic. There is a little reuse of the containers but not enough to matter. I have yet to see a good version of something useful.
I once saw the ability to cut bottles into long strings of plastic but it was too labor intensive. Cool idea if I could stick the bottle in a machine and get string.
Maybe it could be chopped into tiny bits and could be used like mulch in planters to keep the moisture in and the weeds down.
I am not sure though. Do you have any ideas?
