It doesn't _only_ solve long-term logistical problems. Plastics are used for things like takeout containers, drink cups and straws, amongst others - things that are only needed for a short time.
Decomposing isn't a binary process where you wait 17 days and then the plastic disappears. Something that decomposes in 17 days will have ~0.25% disintegrate every hour which means there is now contamination in your food. Personally I'd rather not wait for that contamination to be shown to cause health issues.
What contaminants would result from cellulose-based plastics like in the article? I'd guess probably things that'd at worst make the hot and wet thing taste bad, no?
Bro I’m not agreeing with it, single use plastics are ridiculous. The failure in replacements continues to be what problems they solve for the supply chain.
Unless you want to eat at Applebees, a small, locally sourced, organic, etc restaurant owner can’t conjure up a supply of biodegradable containers. But your local joint can order 5000 of them and keep them in a back room in less than ideal conditions for a year at minimal costs.
Not saying it’s right, just trying to draw attention to reality
Again, not all replacements need to replace 100% or even 10% of plastic use to be able to have an a positive impact. There's space for a short-life plastic just like there's (currently) reasons for long-life plastics
