People dramatically over weight how bad plastic is for the environment. The impact of a 10 min car ride = 10,000+ plastic bags of emissions. And in first world countries almost no household plastic ends up in the environment.

I cycle to the supermarket and every bush I pass on the way is full of plastic.

All of those need to hold hot and wet things for long enough without contaminating them.

Agree, but I don't see any mention of that in the article, so I don't have enough information to argue for that. I'm sure we can agree though that having 17-day decomposing plastics that don't contaminate with heat and water is a good thing, so I hope it is that.

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.

Agree. Give me a metal one or design the cups so that I don't need one at all.

You can buy reusable metal straws online or from a variety of retailers today, and you can remove (or refuse) the lid to a cup, at which point it can be used without a straw. Another option would be to buy canned beverages rather than fountain drinks.

Canned beverages also include a plastic lining.

The problem with biodegradable plastic is that we use plastic so much precisely because it does not degrade that quickly.

UV light (sun light) makes wonders at breaking plastic.

Nobody wants plastic that breaks because this will lead to more trash.

Who cares. If 50% of the usage is short term stuff like takeout, grocery bags, etc then this wipes out that waste.

If even 5% of the time it fails, no one will buy it for those purposes.

I would've said that about ChatGPT, but...

Most would consider The Netherlands to be a first world country, but I understand the term is anachronistic.

As an owner of 30 trees, mainly oak trees, why the heck don't we do this with leaves...? I throw away 3 bins FULL of leaves every week and I can't even keep up. They drop leaves year round.

So... vacuum the forests, like Trump believes? :D

Just saying, leaves are a constantly renewable resource, and as trees get older/larger you get an increased supply naturally

That's true, and as far as my quick research has gone, the plastic is burned off during the smelting process of aluminum recycling.

Because of the small amount of plastic in each can, and the high heat of the smelting process, odds are good the thin plastic liner will be almost fully combusted, which should greatly reduce the amount of microplastics.[1]

The 20 year old me would have been so excited about something like this. The 39-year old (ok 40 next month) is more reserved. It is not that I don't think this will be adapted but more like : What needs to happen (government, civic groups whatever economic forces) for companies to adapt this? It's going to be a slow burn for sure if this needs to work at a global scale but the impetus should begin with incentives, sa…

I think that's beautiful.

you've realized that the problems are not impossible, and it's just a matter of getting people to think about them in the right way.

that's easy. Humans have been getting other humans to think the ways they want since the written word. Nothing is more practiced as a discipline, except perhaps prostitution.
