The underlying problem of course is that recyclable and biodegradable properties are almost always at complete odds with durable, stability during use, chemically non-reactive.

which are some of the tastiest frozen meals on the market, but they not only come in a plastic bowl, but there are two layers of the plastic bowl, one of which is perforated to separate the sauce from the food so that the food gets steamed. Boy is there a lot of plastic.
Thing is, these are all thermoplastics

unlike the thermoset plastic that this article is about. I mean, if you make a plastic bowl out of this thermoset

and use it thousands of times the amount of waste generated is dramatically less than is generated by those steamers. The environmental risk people are most concerned out now is that some fraction of plastics are not recycled, burned, or landfilled and wind up in the environment where they get ground into microplastics. As much as people blame industry on blaming the consumer, it's a lot better to chuck plastic in the trash than to chuck it outdoors and a good idea to pick it up on the side of the road whenever you can. That black agricultural plastic is a disaster. (See also the risk of plastic car tires!)
Also, pulling from memory that may not be quite right, but I recall roads taking a substantial amount of polymer additives and that tire degradation is a major source of microplastic exposure for humans. The tire problem is poised to get worse with EVs being so heavy and accelerating so hard that the tires are bigger and wear faster, but I'm not aware of even any promising research there besides more bio-based feedstocks to improve the sustainability.

it’s like wanting a useful fuel which doesn’t burn. they mutually contradict each other.
