I would much rather incentivize non-plastic alternative packaging. Consumers should have better options for metal cans, glass bottles, etc for mainstream goods, as those materials are far more effective targets for recycling. But they're no where near competitive with plastic because the production cost doesn't account for the total lifecycle.
One way to incentivize recyclable packaging would be to make it illegal for companies to put a symbol on their non-recyclable plastic packaging that 98% of consumers associate with recycling.
We broke the fucking loop by claiming that people could just throw plastic containers away and "somewhere, somehow (over the rainbow!!!) people will recycle them into new goods". That story is bullshit - even for most plastics that can actually be recycled.
I want legislation that lays out a set of standardized form factors that are as re-usable as possible (NOT RECYCLABLE - Literally washable and reusable), and if companies use those - great! No extra taxes for you.
Want to use your own custom packaging? Fine, but you pay for the whole fucking product lifecycle up front, before the customer ever touches it: Collection, Cleaning, Recycling/Disposal, Reprocessing, Redistribution. The EU estimates those costs for plastic at about 800 EUR ($950) a ton.
