The important point is that this mechanism works only for the so-called semi-crystalline plastics. Even if they are less frequently encountered, there are also completely amorphous plastics and completely crystalline plastics, and these appear to not be prone to fragmentation into micro-plastics. The conclusion is that there should be efforts to develop alternative plastics to the more frequently used semi-crystalline plastics, which have this serious disadvantage of generating persistent micro-plastic fragments. Therefore this article offers a potential solution to the micro-plastic problem, which might work, like when freons have been replaced with less harmful refrigerating agents, even if those may have a slightly less refrigeration efficiency.
