I don't remember energy use being the problem with plastic bags? It was plastic bags being absolutely everywhere in the environment. Streets, parks, trees. Wrapped around anything sticking out of the ground. On your face on a windy day. Pollution is the problem with plastic. Probably health, too, now that microplastics are being recognized as an issue.

Every winter in my city, once the leaves all fell, our trees would be draped in shredded plastic bags. Banning single use plastic bags has done a significant amount to beautify this place.

Yeap. In my pantry right now, I probably have 12 reusable bags. Some of them have been used hundreds of times (and have the battle scars and stains to prove it) while others were used once because I had to run into a grocery store unprepared. The math probably averages out to a slight advantage for reusable, and that doesn't take unique use cases into account: for example, I found every container I owned useful during a recent move.

I'm sure skeptics like the article's writers would tweak some numbers to say disposables have an advantage, so who cares? The fact is there are less gunky, sludge-riddled bags in the gutter of my downtown and that absolutely justifies the bans, despite what this article or the NY Post might argue.

Every now and then I'd come across articles from this source and thought that they were decent. Perhaps not the best, but reasonably well researched and argued. But coming across this statement kind of sealed the deal for me in the wrong way: > Instead of paying more to recycle, we could spend that money far more effectively on other environmental mitigation measures like carbon capture. Pure unadulterated bollocks,…

I agree with a lot of what you’re saying but flagging a post because you no longer trust the source is a misuse of the functionality.

"Instead of paying more to recycle, we could spend that money far more effectively on other environmental mitigation measures like carbon capture." Yeah, let's stop doing the fairly well established recycling programs that have knock on benefits like reducing pollution, and instead start scaling an entirely unproven and expensive mitigation program. These are some prominent Effect Altruism guys so I know "cause prior…

ALSO, what is the obsession with embodied energy?

Like lets think about plastic bags from an object use standpoint. Given you have a collection of stuff to carry would you prefer:

A) A reasonably sturdy bag that can be styled to your preference (like with art or whatever) that you have to remember to bring with you when you need.

B) The literal minimum possible material to be considered a bag. Even money whatever you put into it will punch straight through the bottom, or you'll need to use 2-4 nested bags anyway. And it'll be uncomfortable to hold the whole time.

I think from an object use perspective a reusable bag is more pleasant to use.

But embodied energy calculations are convenient because you can get numbers to compare. But it ignores externalities.

Like if you actually considered the embodied energy of the median tote bag vs the median plastic bag from the point that it was extracted from the ground to the point that it returns to dust, I think the story would look really different. I'll bet a sizable percentage of plastic bags don't even make it through their first use. Meanwhile I've got tote bags that I think are fully 15 years old. Plus if you consider the remediation future generations will need to do for plastic bags. meanwhile I can actually bury a cotton tote bag in the dirt to decompose and it doesn't need infrastructure to prevent poisoning the water supply.

Did the authors consider the embodied energy of the landfill itself? Shipping? Trash collection? Ongoing monitoring? The embodied energy of the future carbon capture system?

It's just so convenient to look only at the materials, equate that to kg of co2, and use that for whatever narrative makes you feel good.

I suppose you're correct, and it's my frustration speaking there. That said, the internet is absolutely immense in terms of articles to read, an arguably poor source is simply not worth the effort.

I think using a cotton bag 173 times to beat plastic bags and a mug 1,000 times to beat disposable cups sounds completely reasonable.

Can you use the cotton bag 173 times? Cotton wears out over time. They also didn't ask about the cost of washing the cotton bag, which really should be done once in a while since they collect dirt and food particles - this will increase the times you need to use the bag. (it isn't clear if it lasts longer with or without washing - dirt is often sharp enough to wear the bag, but washing also puts wear on them) Similar…

> Can you use the cotton bag 173 times? Cotton wears out over time.

Yeah, comfortably. Shopping bags don't actually get much "wear" in each active use period. The main issue will be the handles but good stitching will solve that.

And it'll go in the washing machine with your clothes (though you might want to tie the handles together).

I have a Lidl bag that is already into the sixties of usage (it has been my food shopping bag for more than a year).

I have other two reusable bags made from recycled polyester (so recycled plastic bottles and plastic bags) that have seen probably 1800 uses each, maybe more, in their lifetime.

This material is probably a better choice for reusable shopping bags anyway; it can be made from plastic that can't be reused for food grade, it's incredibly tough, it folds down small etc.

Just let me buy things without forcing me to buy so much trash too. Every grocery store item is over-packaged.

Strongly agree. I wish more things came in jars, cans and sacks. I would pay a premium for this alone. The plastic liner in a tall box workflow adds so much friction to storing using and disposing groceries. I despise cereal boxes.

Earlier quoted context omitted.

But the pollution problem from plastic bags is solved equally well if we bury them or recycle them. Provided your municipality doesn't just dump trash in the nearest river which is an issue in some parts of the world. Since we can't get 100% compliance in rich countries and poor countries can't afford landfills that's a good reason to not use plastic. But it's not a good reason to have plastic recycling programs.

> But the pollution problem from plastic bags is solved equally well if we bury them or recycle them We can't even reliably trust people to put the plastic bags in a bin and have that bin be cleanly collected and yet you're expecting people to bury them?? No, the solution is to massively reduce how often we use single-use plastic bags. It seems like every time I buy anything from any store its just assumed I want it…

>We can't even reliably trust people to put the plastic bags in a bin

We can, or more precisely it depends on culture norms. Places where littering is rare do exist.

The argument that is pro-polyethylene plastic bags over cotton completely ignores the source: Renewable plants that are grown and harvested, vs. finite fossil fuels extracted from the Earth and refined. > Instead of a simple blowing and sealing process, the cotton must be made into yarn, woven into fabric, prepared, dried, sized, dyed, and finished, which takes around 1,725 megajoules, around 3,050 times as much ener…

Broadly, I agree with your comment. I have seen a few experimental plastic drink bottles that claim to have a minimum percent produced from plants. It is a little bit insane to imagine the amount of chemical and energy gymnastics required to make plastic bottles from plants, but, hey, the big drinks companies are desparate not to lose PET bottles. To be clear: I am not defending this type of plastic! I am only pointing out that it does exist.

    > That conveniently ignores the drilling, extracting, transporting, refining, and transporting again to make "polyethylene resin".
This is really the key point! There are comparing apples to oranges.

Somewhat adjacent, in many rich countries, in the last 10 years there has been a big push to remove plastic drink straws. I think it might have worked. Initially, the designs and performance of wax coated paper straws were pretty terrible, but chemists and material scientists have been working hard to improve the product. I feel like paper-ish drink straws are here to stay.

Proper recycling improves national security and the well-being of their citizens.

Good example is South Korea. They were devastated after continual war in the 1950s. So they implemented mandatory recycling. Food waste goings into bin A, metals into bin B, plastics into bin C, ... This allows for reducing the cost of recycling by presorting items. It helped them rebuild and become stronger. To this day they still properly separate their garbage to ease recycling.

Recycling food waste and scraps means creating a nutrient rich fertilize resource. Tossing them into a land fill removes nutrients from the food chain. USA food has less nutrients than years past because of the push for synthetic nitrogen fertilizers.
