Relying on humans to do the right thing with the bottles is a good intentions solution. And in tech, at least, we don't like good intentions solutions. If relying on good intentions worked, we'd already have solved the problem because people already have good intentions.
Instead, we need to make it impossible to do the wrong thing. How do we make it impossible for plastic bottles to end up in the river? One way is to stop making plastic bottles.
If we stopped it at the source - and forced these companies to spend a fraction of their massive revenues into innovating around more sustainable alternatives (effectively just pricing in the externality that they are currently getting a free ride on). You'd end up with a much better scenario where consumers can still enjoy the products and don't even have to deal with the cognitive overload of sorting 12 different types of waste.
I think one of the biggest coups that governmentes & corporations have pulled off is to let the burden of environmentally friendliness get shifted to the end consumer. This means that it requires masses of people to first get informed, then get mobilized and then start boycotting or putting pressure on these companies to change something. Pretty wasteful cycle if you ask me, easier to price it in much earlier at the source.

Placing the cost of disposal or pollution (best that regulators can assess that) upon the producers seems at first glance to create many of the right incentives, such as improving packaging, reducing waste, increasing recycling, more effective disposal, and modifying consumer behavior in the only way that seems to be universally understood: the price of goods.
