I already use cellulose based bags for my compost waste, and they only stay reliable for about 3 days of usage after something is put in them. This makes them a huge pain to use. I think they also degrade quite a bit (i.e. shorter lifespan in use) after just a few months because each new roll of bags seems better at the beginning.

I put my bags + compost in the fridge freezer, which prevents smell and also prevents the bag from biodegrading before I can take it out.

I recommend this approach in general.

I would kill for this for when I’m buying fresh produce at the shops. Right now I just raw dog the produce into my basket as putting 4 apples into a plastic bag to ease the weighing and transport home seems like a selfish thing to do to the environment, but something that starts to break down soon after that sounds great.

SAME. It kills me inside when people wrap things like fruits and potatoes in plastic that have natural peel they'll remove before eating anyways

It's a miraculous thing corporations have done convincing us that we're the ones polluting the environment.

I grapple with this all the time. my wife is very eco-conscious and will scrub out a deeply moldy glass jar just to recycle it (whether the recycling system works is a separate issue here). On one hand there is some truth to the fact that if we all just work together to do the right thing the world is a much better place to live in. Sometimes i don't want to do this (scrub gross shit out) because i'm lazy, other times it feels futile. or maybe its just that the latter is a good excuse to be lazy.

I'd argue that even thinking about the idea of recycling and eco-conscious behavior is something only the already wealthy (with respect to the rest of the world) can do. There are plenty of developing nations where consumption and pollution run rampant and unchecked and unregulated which do tons more damage than me throwing 1 glass jar into a semi well managed landfill.

I mean theres just so many facets to this - does recycle work, does collective action work, or are corporations the real devils here doing much more bad than the collective at large?

i feel that the only way to change anything is through government level policy (which also feels futile), but individual actions do little without policy+propoganda to disseminate the right message and change collective behavior.

We have been using linen bags from Rough Linen and have been pretty happy with those.

Why don’t you bring plastic bags from home? They are very much reusable, you don’t have to throw them out. They are also quite easy to fold into small shapes and keep on you, or your car, or whatever. I have plastic bags which have endured for literal years. I also decided early on that if I forget to bring a bag, I either do without or have to go back to get one. You start remembering really fast after a few times o…

This. HDPE lasts. So reuse it.

Cardboard not so much, but where I live one can just take how many boxes one can haul off various shops and they will just thank you.

Where I live they have scales that tare at the beginning as part of the process of using your own bag.

Do you write down the result? How is the process connected? Smart produce scales log weight => Smart checkout scales compare weight to produce logs?

Write down -what- result.

You put the bag on the scale, it then sets this amount to 0.0

You put the product on the scale, (say 500g of apples), It shows 500g.

You remove the bag, it takes off 4g, you add the bag it puts on 4g.

There is no need to write down the result.

If I’m not mistaken this is ecologically basically a paper bag that looks like a plastic bag. Remember when we all switched from paper bags to plastic bags to save the environment? The environmental issue isn’t plastic bags, it’s that you don’t reuse them.

> it sounds like I'm just describing something like petrol in a solid form at room temperature That's what plastic IS. That's why it sounds like it, because plastic is in fact solid hydrocarbon. So not only is it not farfetched, it exists today, which is also why incinerating plastic for energy is the best possible way to dispose it. You remove the plastic from the world, you reduce the amount of oil pumped for fuel,…

So do we already do this? And if not, why not?

We sure do, Sweden imports trash (actual trash, not recycling) because it's a huge part of their energy source.

A large amount of plastic recycling is burned, but always in secret, because when people find out they freak out, because they mistakenly think that making some new plastic out of it is somehow better.

Municipal waste has a large fraction of waste from demolished buildings which includes wood, concrete, bricks, all sorts of stuff. PVC is a significant part of that waste because it is used for siding, floors, etc. In a consolidated municipal waste stream heavy metals are a concern because they concentrate in the ash which has to be carefully stored. This kind of system https://en.wikipedia.org/wiki/Plasma_gasificati…

How is PET not a hydrocarbon (for the purposes of burning it)? It's (C10 H8 O4)n the oxygen makes it not technically a hydrocarbon, but it will burn just fine and cleanly. Your point about building waste is valid, but I think most of that stuff goes in dumpsters and can be directed to a different wasting handling.

Hah.

We burned shavings/rejects from a polyester-resin+glass boat building.. in a 200L drum.

That was quite smoky and smelly, but still I think better than just shipping it all off for burying in a landfill. And fiberglass decomposed basically into fine sand too.
