Just returned from my hols. Went to use the washing machine and they would not let me use ‘pods',only the new style ‘melts' paper strips for environmental reasons. Simple question,does PVA contain micro- plastics ?
Not sure but apparently algae can digest it. So I would think it's safe.

Algae eat the plastic, fish eat the algae, we eat the fish.
It might be that PVA is not be as good for the environment as we first thought. There is a difference between dissolving and degrading. Any chemists out there?

Seaweed is a type of algae,I think.Boffin reqd.

As I understand it dissolving PVA products are designed to break down into hydrogen, carbon and oxygen on contact with water. Once dissolved they are gone and leave no toxic by products. This is a chemical reaction that is temperature/time dependant.
Microplastics are a whole other ballgame.

everything contains microplastic to some degree, even we have it in our blood but in fishing pva is the least you should worry about, plenty other plastic and other waste we dump around in water and on banks is much worse...

Think your right there darkol. A search of the internet shows that polyvinyl alcohol is used as a food glaze for human foodstuffs

Isn't that PV acetate rather than alcohol?
Anyway I believe your original problem might have been triggered by some water treatment plants that have problems treating PVA presumably from washing pods.

Think acetate is the dodgey one. Alcohol version is used in lots of applications. Good info on puracy.com

You could be right about the problem with pods possibly not melting at low temperature 👍
