Yes, but the main issue is how mixed the materials are in our consumables. Mixed recycling is basically bullshit. We should have more standardized packaging and more categories of separation strictly enforced. Japan does this pretty well.
You could opt in to pay extra for sorting if you can afford it sure.
And emissions need to be better taxed, and illegal dumping and discharge into rivers and such a jailable crime with big fines for businesses with accountability going right up the chain to investors.





That’s a result of Tokyo and the other biggest cities only separating into recyclable bottles, non-recyclable or non-burnable material (i.e. inorganics) and all the rest which is as you say incinerated.
They also have some, if not the most clean burning incenerators in the world, and they use the waste material for construction and land reclamation.
Burning plastics at very high temperatures is far more environmentally friendly than sending them to landfills or attempting to recycle them.
Nevertheless they are known for excess packaging and obviously my arguments about standardization still apply to Japan as much as anyone else.
