Single use wooden items don’t cause flooding and damage wildlife.
These are not the same. They don’t have the same problems.
Burying is not the same as being thrown in the ocean, or ripped into little pieces and thrown on the ground.
Burying would likely keep plastic in the immediate vicinity, and we have another tool to add. Bacteria.
There are bacteria which eat plastic. If we could find some anaerobic ones, burying might work quite well.
Of course I guess that leaves the carbon free again, unless...
We find or engineer bacteria which produce a great precursor, to make plastic!
It would be a strange outcome, if plastic became fully renewable.
AFAIK its paper, sure but laminated with aluminum and plastic so good luck separating the layers into recyclable stuff.
Not that recycling is a panacea in the first place… more like a gimmick to make us feel good about wasting so much instead of questioning the methods of the industries producing all the waste in the first place.
