Rule 4- No self promotion or upvote-farming of any kind.

That's it.

I read somewhere that because recycling plastic isn’t profitable, under the capitalist system there’s no incentive to do so.

Most plastics due for recycling just gets shipped off to poor countries for “reclycing” but isn’t at all, and a lot of it just ends up in the ocean.

So you’re better off just throwing plastics in the garbage where it will at least end up in landfill and not in the ocean.

It's because you can't recycle plastic really. Each time you heat it up to melt it it loses its properties. A recyclable material is for instance aluminium, which keeps on being awesome. I tried various recycled plastics for a business I run, none of it was strong enough. Recycled lego, recycled car bumpers, nada. And then the question is - why would I buy the recycled plastic that doesn't work when it's like 30 cents cheaper. Pellets are so cheap in fact, that I could buy a tonne, use up 100kgs, throw the rest away and still be fine.

Once they touch the factory floor's floor, plastics become filthy and cannot be used for high-quality applications - food wrappers, anything with body contact. Oils and heavy metals are the biggest contaminants, a plastics-producing company I used to work for concluded. They either sent it all to a recycling factory or used it for very low-quality stuff like trash bags.
Now with post-consumer plastics, not only are they extremely heterogeneous, they will also have even worse contaminants like mold which proved to be very resistant to cleaning, a EU study concluded. So you might want to pyrolyze them like you do with crude oil, but there's just too much O, N, S and halogens, so the output will be too corrosive, but also too heterogeneous for it to make economic sense.

[–] Classy@sh.itjust.works 2 points 3 months ago

What was it like working in plastics production? I imagine you were breathing in vapors all the time?

[–] MonkderVierte@lemmy.ml 2 points 3 months ago* (last edited 3 months ago) (1 children)

Maybe with some additives? Or removing them, in the first place? But expensive i guess.

[–] Maalus@lemmy.world 4 points 3 months ago

Maybe there is something, but tbh why bother when virgin pellets are better. The best plastic recycling strategy is to not make it in the first place. Or just use other types of packaging - alu cans, glass bottles, paper containers, whatever.

Also additives soak water like crazy. Moisture is a huge problem when making parts - you need to dry some types of plastic pellets in industrial dryers, which eats up a ton of electricity - since they are often running off of compressed air out of a compressor. Most plastic comes in natural colors to which you add additives to change to the color you want. Simply doing that (2% by weight) is a difference between not having to dry at all (since some plastics just don't absorb water - i.e. polyolefins - which high density variant is what bottles for shower gel, shampoos are made of) and having to dry it for like 6 hours before use.

It's just a bad material that's cheap to make things out of.

Once used, to my knowledge, it can't be reused as the same thing, so they "recycle" it into road surfacing etc, which I'm sure doesn't end up fragmenting into tiny bits over the years and ending up in water sources...

And I'm not sure there's a good way to get away from it completely. Even drink cans have a small layer of plastic inside to stop it reacting with the metal. Glass is probably the most environmentally friendly (if you just wash and reuse), but a bitch to get it back in one piece.

Time to tax the ever loving shit out of plastic tbh. And yes, prices will go up, but you know what? They go up anyway. They can only take as much as we have, and they're already taking it.

[–] roofuskit@lemmy.world 3 points 3 months ago

Most glass is recycled into asphalt. Until fairly recently that was the only way to recycle glass.

That's a bit cynical take. In many countries, including mine, there are dedicate bins for plastic waste which is the majority of waste from your typical household. It's all being recycled into new products, not being shipped anywhere. Also, when it comes to plastic bottles for example, close to 100% of them are returned and recycled into new bottles. I've got a tiny-ass bin for the stuff that ends up in landfill because I separate and recycle it all as does most other people.

EDIT: Nevermind then. It's all apparently dumped into the ocean. Sorry about the attempt in some positivity.

Seems far more likely that the recycling rate is low because not every piece of plastic waste is put into recycling. Not that they simply don't recycle it.

[–] Tiptopit 3 points 3 months ago

The problem is that there are quite some different sorts of plastics and that plastic containers are not standardized. If you mix different kinds of plastics or plastics with other materials you can't use it anymore in an automated processing and it usually gets burned. Also mostly recycling is a downgrade, so usually if you recycle some packaging, it is not made into packaging again but into things like pallets or construction fence bases.

[–] frazorth@feddit.uk 6 points 3 months ago

It's all being recycled into new products

I'm afraid its not. There are many plastics that don't have any method of recycling, and plently more that require specific machinery for their "one time" recycling that just isn't being used.commercially.

when it comes to plastic bottles for example, close to 100% of them are returned and recycled into new bottles

Even the PET bottles can only go through the process once or twice before becoming too degraded. That's not even taking into account that most manufacturers want white or clear plastic, and recycled does not work that way.

The separation and recycling that you do is mostly gaslighting and green washing.

[–] Badeendje@lemmy.world 5 points 3 months ago

Haha.. yeah I live in the Netherlands. And my city started separately collecting plastics.

Here's the kicker: because there is no more plastic in our waste, the energy value of the waste went down. The city sold these waste "rights" to an incineration plant that reclaims heat and energy who now cannot use the waste. So to avoid contractual fines, our city now imports plastic waste from elsewhere in Europe to be mixed in with the waste and then incinerated.

Well fuck me!

  • This is more expensive for the city (separate bins, separate collection, separate processing, buying plastics from elsewhere and getting it here)
  • All the extra transport and shipping movements is worse for the environment.
  • I'm stuck with an extra fucking bin, and with both a greens bin and the rest bin that are collected once every 3 weeks instead of 2.. stinking up the place even worse.

But I'm sure they meant well.

[–] frazorth@feddit.uk 4 points 3 months ago

Even if you look the Scandinavian countries which generally does better than the rest of the world, you are looking at only a 25% recycle rate.

In my country (Aus), last I heard our recycling was mostly shipped off to Indo or somewhere else in SEA (previously China before China banned it).

I suspect very little ever sees recycling, but the neoliberal model means privatised companies paid by government, so they’re out to cut expenses to maximise profits and shipping it off to someone else to do the illegal thing where it’s not illegal isn’t illegal.

I read somewhere that because recycling plastic isn’t profitable, under the capitalist system there’s no incentive to do so.

Not just unprofitable in a capitalist sense, but inefficient. A typical plastic beverage container can be recycled two or three times before the plastic degrades too much to be usable.

Socialism won't save you here. Unless said socialism bans plastic products.

[–] roofuskit@lemmy.world 3 points 3 months ago

Those countries stopped accepting it.

[–] MonkderVierte@lemmy.ml 1 points 3 months ago

Gets burned here, same result like with oil it is made of.
