How much plastic is escaping into the environment from the recycling process vs. landfill? What are the CO2 output of landfill vs. recycling? I imagine burning would be the worst option for these.
Not surprised that the market forces tended towards the most energy efficient waste disposal systems; glad we don't have mountains of trash or poor landfills.
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.
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.
I'm curious what happens to these landfill sites in 100, 1000 and 10k years. Do they inevitably break down and leak into the water table? Do they eventually stop off-gassing and become inert? Do they become fossilized layers of sediment on a long enough horizon? If we maintain our current waste levels, how much land is required by the year 3000?
> 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 energy.
That conveniently ignores the drilling, extracting, transporting, refining, and transporting again to make "polyethylene resin".
It also ignores the energy requirements to grow the cotton. This isn't the gotcha you think it is.
however i have never re-used a paper bag because they are awfully loud and cannot be compressed. it is the worst kind of bag.
There are cases of shipping trash around, but it has more to do with it being cheaper to send a container of garbage somewhere than dispose of it locally.
Cost is the constraint, not available space.

It's much more the case that we ship plastic to be recycled to other countries than trash. The problem is that then the unrecyclable plastic mixed in often ends up in rivers.

My understanding is that biological decomposition of waste creates methane which is a worse greenhouse gas than CO2.
The methane that landfills produce is routinely captured and burned for power, they may otherwise flare it off before it can contribute to the greenhouse effect. This is also mentioned in the article.

> A molecule of methane traps more heat than a molecule of CO2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere. CO2 can persist for hundreds of years or more.

This seems like the weakest of presented arguments. Just 10 trips and it's more environmentally friendly? Yeah, seems like reusable milk bottles wins over plastic. That's what, ~10 weeks for payback?
In Switzerland grocery stores have been promoting reusable (recycled plastic) bags for years, and people use them for everything: I saw someone in Interlaken carrying firewood with one.
That episode has always stuck with me, and I've always wondered how valid their argument is.
Of course, this requires you to have less trash , which is very easy if you simply take a few seconds to go outside and throw your food out after lunch/dinner. Everything else is just dry scraps usually. There’s always the fridge :)
All in all, there is no concept of “garbage”, “garbage bin” , or any kind of “garbage accumulation” in my apartments.
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 in a plastic bag. Getting a single bottled drink at a convenience store? The clerk gets a plastic bag ready. Its insane.
The state government response was to ban the ban of plastic bags.
