Are there any actual concerns with pure PLA?
- WhatIsDukkha 3y ago"Environments without the necessary conditions will see very slow decomposition akin to that of non-bioplastics, not fully decomposing for hundreds or thousands of years.[59]" https://en.wikipedia.org/wiki/Polylactic_acid#Degradation https://en.wikipedia.org/wiki/Polylactic_acid#Degradation No mention of its actual life cycle as it turns into a microplastic ie so it should be presumed dangerous in the same ways.
- K0balt 3y agoAs a microplastic absorbed by organisms, it is quickly absorbed. But idk of what absorption means to the absorbing organism, hopefully we have some data on that. Absorbed might not be the same as harmlessly absorbed and metabolized.
- mypalmike 3y agoI suspect they are referring specifically to PLA.
- zik 3y agoPLA pretty much just breaks down into microplastics unless it's decomposed in an industrial composting facility.
- dTal 3y agoThere's no such thing as pure PLA, like all industrial plastics it's filled with additives to improve its properties and these have endocrine disrupting / carcinogenic properties just like all the others.
- droopyEyelids 3y agoEndocrine disrupting plasticizers are not used in all plastics, and they’re not used in basic PLA. You really cant generalize “all industrial plastics” as “plastic” is way too broad a concept. Good engineering plastics like PEI/PEEK dont even need to use any additives like plasticizers, stabilizers, cross linkers etc.
