You don’t need to accurately price them. You just gradually keep increasing the price year over year until the companies spin up R&D departments to switch to biodegradable sustainable alternatives, or their competitors do. You have to hit those corps in their pocketbook and affect their bottom line before they act. It’s the only thing they understand. As far as cleanup - forget it. We may be able to clean up the Great Pacific Garbage Patch, but we won’t be able to remove microplastics around the world. It is urgent we stop creating MORE though. That means also mandating drainage systems that filter and trap these particles before they escape. We already mandate that for many forms of grease!
