Indeed, and I feel that way to contribute is to just add all your plastics to the recycle bin, hoping that even the most difficult types will reach a threshold amount that will trigger research into their recycle-ability, or at least into better separation techniques. Please show me I'm wrong if I am.
It makes recycling more costly, as the recycling factory have to spend more time sorting it, or just refuse recyclable garbage because it's mixed with non-recyclable and sorting is too costly.
Well, as I don't have spectroscopic eyes to identify the nature of the polymers I have in my hand as I make a choice between bins. And the fact that plastic is a rather broad term combined with the vague communication, I'm going to keep doing this as do many others. So I just hope innovators will find ways to separate better.
I use to do this but it's actually contributing to the problem of wish cycling and why other countries have begun refusing to buy our recycling due to impurities from sorting. Just Google your city name + recycling rules and you'll be able to contribute without being the problem.
