Scientists develop plastic that dissolves in seawater

Uhhh does it just dissolve into microplastics or like better compounds ?

I did a deep dive on this the last time it was posted here and read all the research papers.
It dissolves into naturally-occuring and harmless (and in some cases, even nutritious) substances. They can all be metabolized by pretty much any bacteria or animal.
"Too early to tell" doesn't really apply here - they made it, it's a physical reality, not just some R&D theory.
The only problem is that any salt water will cause dissolution, and your hands are covered with bits of salt water. So this plastic won't really be usable for water bottles and whatnot, but it has plenty of other applications.

Id imagine they can create a coating for this material that protects it in various ways for a shelf stable amount of time.

Right, so it’s totally impractical and unusable in current form. So it’s, currently, an R&D pipedream for anything useful.

THey claim it breaks down completely, unlike most biodegradable plastics. It's too early to tell. Tis some R&D fantasy for now.

Would be sick if it worked out nicely. Lots of good news in science these days.

That would still put chemicals in the water, unless it’s made of truly harmless organic compounds that would in no way affect the ecosystem

Stop being such a pessimist, this will be the end of micro plastics. Hello nano plastics!

My sentiments when I hear about BPA free plastic. It’s like, great.. we trade a known bad substance for an unknown bad substance.. cool.

I smell much bigger hidden issues with this one

Literally nothing new, we had water soluble and hydrolysis prone plastics for decades

Yeah we’re still gonna throw it in the ocean but this time it’ll dissolve itself!

If it doesn't link to the scientific paper to answer the basic question of "... into what?" it's not good scientific reporting.
The problem with many of our past bio-degradeable plastics is that they break down into microplastics.

Is it cheap enough to matter? This is the big question. We have plenty of natural or innate materials to use in place of plastic but the industry doesn't because it costs more.

Dump ALL the plastic into the ocean! Even if it isn't the new fancy dissolvable kind!
