It's nice that plastics/microplastics will be gone but it's still very concerning in terms of their plasticizers and other impurities/contaminants making their way into the food chain, as those are potential endocrine disruptors.
Not necessarily. They can still be infused with antimicrobial chemicals. The longevity of the plastic would then also be determined by those additives, since those would have their own half life too.
