I doubt it’s 100% cornsarch. I work in the plastics industry and there’s all sorts of travesties going on. We also have a line of cornstarch-made products, but they’re all scams when it comes to “recycling” and “being biodegradable”.
There’s definitely plastic in it.
Polylactic acid is made via condensation of lactic acid, which can be made entirely from corn. It’s still plastic, but just made from renewable sources. It’s pretty recyclable and can be industrially composted, but in normal conditions it lasts as long as any other plastic.
but in normal conditions it lasts as long as any other plastic.
I am by no means an expert on the subject, but isn’t this basically the entire problem with plastic in the first place?
It’s nice that this stuff is renewable and recyclable, but if it isn’t properly recycled, it sounds like we’re going to have the same problem we already have with existing plastics.
Yeah no, it’s only marginally better. All my information comes from 3d printing, which is even worse since there’s no way to recycle it since no recycling symbol. More accessible industrial composting would help though
I don’t know what you are doing in the plastics industry, but it seems that you don’t understand what words “biodegradable” and “plastic” mean.
PLA is biodegradable. Just only under industrial conposter conditions so yeah still a problem.
But a plastic is just a chain of polymers, it makes it difficult but not impossible to biodegradability depending on chemical and structure. Almost all plastics don’t but some do
