‘Compostable’ plastics no longer able to be composted in Boulder

The only way is to reuse and stop using single use items.
"Grow everything yourself and never interact with society" doesn't seem like a very fulfilling life to me.
Most produce doesn't need stickers or rubber-bands for example, nor does it need individual packaging - the packaging can be provided at the supermarket in the form of a single plastic bag.
> The only way is to reuse and stop using single use items.
If you don’t have a car and only go to the supermarket occasionally on the way back from somewhere else you’re very unlikely to have a bag with you, so you end up buying the “reusable” bag every time and at this point I’ve thrown away several hundred of those over the last couple years as they accumulate at home and I have no use for them.
That can‘t be too hard and you should be able to figure that out without wasting several hundred reusable bags
Accumulating & eventually throwing away the reusable bags in bulk is a minor inconvenience compared to making sure I’ve always got one on hand which I pretty much always fail at.
Natural rubber or synthetic? The former is biodegradable and compostable at industrial facilities. Don't put rubber in your backyard compost bin, though, even if you're 100% sure it's natural.
I agree about the little plastic stickers, though. Those are an abomination.
I used to volunteer with a group that got compost from the yard waste composting facilities in Seattle, and that stuff was full of banana and apple stickers. And that’s presumably after it had been through a screen. Microplastics or soon to be.
I don’t know what the alternative is. If you want to write your congress critter it helps if you have an alternative suggestion.
And I guess there are edible inks (which at least offers the opportunity to remove the plastic, even if it still off putting).
Those second stickers you see the stores put on, I haven’t seen those in the compost, so I’m suspecting they either break down or compost, but the distinction is important. Invisible plastic is still plastic.
It sounds like a great life to me... but not very realistic in this day and age.
Plastic is a fantastic material for reusable items of sorts, but it doesn't belong in a single-use drink cup, food container, or bag, until we have the technology to truly recycle it and the law enforcement to require that said recycling happen.
Execution is important. I've been seeing so much fuss about banning plastic straws but no fuss about the cup. I frequently see drinks in plastic cups with paper straws. Completely backwards.
The very few remaining items are typically cleaning supplies such as bleach and hazardous cleaning agents but for safety and hygiene purposes I do not consider those a high priority for finding non-plastic alternatives.
Please note that I do not include the several-microns-thick coating of plastic that coats the insides of some cardboard boxes and aluminum cans as "plastic output" due to its total annual weight (in my case) being less than that of a single bottle of shampoo.
For shaving I use a safety razor, whose blades come in cardboard. For shaving cream I use a puck that comes in cardboard packaging. My toothpaste comes in compressed pellets and all of my soap, even shampoo, comes in bar form. There are currently no plastic single-use items in my bathroom. Even my toilet paper is purchased in bulk, 80 rolls at a time, and comes in a large cardboard box with each roll packaged in paper. It is a recognizable brand's "Industrial" product line.
Rather than paying for water most of my cleaning products are purchased in powder form, usually under a recognizable brand's "Industrial" product line, in bulk. This means that yes, I do buy a 5-gallon bucket of laundry detergent but in over a year after I have finally used it all I have a reusable 5-gallon bucket that does not go into the waste stream. You can also buy items like that in cardboard boxes lined with a plastic liner but even then the volume of plastic is, after many years, less than that of a single plastic laundry detergent container which only lasts months.
Even cleaning products that, again for health and safety reasons, come in plastic containers I buy them in bulk, dispensing them into reusable (and much higher quality) applicators. This means that the (realistically) unavoidable use of plastics is minimized. The amount of plastic used in a single 128-ounce bulk "industrial" cleaning bottle is less than that used in 4 32-ounce (typical sized) bottles and the reusable (again, "industrial") spray bottles I use to apply the product last for years if not decades.
For food items I typically do not buy anything that comes in plastic with the main exception being sliced bread, but again that volume of plastic is so low it is almost irrelevant. When I realized that I was throwing away ~30 plastic yogurt containers per month I started making yogurt myself in an instant pot and storing the yogurt in glass jars. Doing so requires almost no effort-- the instant pot does it for you. I've been doing this since 2011 with the same jars, which will probably last another 100 years, so I have not thrown away over 4,000 yogurt containers.
In your example, the rubber bands and stickers are irrelevant. Years, if not decades, of rubber (assuming you mean synthetic rubber, natural rubber is fine and will biodegrade) bands and stickers add up to a single bottle of dish soap's worth of plastic.
Plastic is a wonderful material but it is immoral, to me, to use it without foresight of its impact and costs.
It requires effort, but is not "hard". Effort does not equal "hard".
My anti-plastic crusade started because I live on the Chesapeake Bay and became involved in Bay cleanup initiatives about a decade ago. I'd say 9 out of every 10 items I recovered were plastic items, some from as far away as New York State, having floated for hundreds of miles down the Susquehanna and Delaware Rivers.
As consumer there are only limited ways you can reduce single use. We need to change the economics so excessive packaging is too expensive.
Firstly I now have to buy garbage bags, where I previously reused shopping bags. That completely negates the benefit. But let’s ignore that and say most people just trash them.
Even in that case you’d have to reuse a reusable bag 20 times to break even. I don’t know about you, but on average maybe I get 0-5 reuses out of these bags. That’s just squarely worse off than we were before.
I'm waiting for someone to invent the re-usable dog-poop bag. ;)
I’ve had the same reusable bags for probably 5 years now and not a single one has failed.
As in all things, moderation, do the 80% etc...
Hey if you've been using the same bag for a shopping trip every day, for all that time and never replaced it or got another, and it wasn't organic, you're almost halfway to having a smaller environmental impact than just using single use plastic bags all that time.
https://www.cnn.com/2022/12/13/world/cotton-tote-vs-plastic-...
So you'd need to reuse a cotton bage 70-1000 times most likely to come out ahead. Or you could reuse cotton you already have and lower that number to effectively 0.
Sure if you got random cardboard one it won't be that great
Shopping bags were always terrible garbage bags able to hold only tiny amounts of trash meaning you had to use a ton of them and as many as you needed the average household received 100x as many bags as they could profitably use as trash bags. Consider throwing everything wet into centrally located large trash receptacles with large bags and either not lining small trash cans or lining them with paper bags.
TLDR buy better bags and use small paper bags.
In the Great Depression and then during several nostalgia cycles after, companies sold products in or with reusable containers. Everything from tins to depression glass was a value add for the products. Your grandma may still be keeping sewing supplies in old cookie tins, reusing Ball jars that food came in, etc.
It sounds like the recycler they're using only has the correct facilities to process some but not all of these PLA plastics and are having contamination problems with people putting non-compostable things in along with the compostable ones.
They're also refusing used coffee filters so it seems the problem isn't plastic industry scams but poor compliance with people putting the wrong things in the compost bin.
I've known several well intentioned but slightly clueless people who put just about anything in the recycling or compost not realizing that they were just contaminating the stream and making things much worse. It's almost the opposite where recycling/composting proponents are giving and getting wrong impressions about how much really needs to be put in the landfill.
I live with people who keep putting soiled cardboard in recycling. Only last year did I win the war on pizza boxes.
In general coffee grounds should be compost. Maybe people were trying to compost whole coffee kureg pods or something?
Coffee is wonderful on its own for composting. It’s very nearly the correct C:N ratio just by itself.
Reuse could actually work. If we were to standardize on thicker plastics, that could last longer, we could just have like 10-20 standard container sizes and constantly reuse them.
IMO the biggest benefit of compostable materials in food service is that they have a decent chance of eventually degrading to safe materials if they end up outside a landfill.
The captured methane can either be flared off, or used as a fuel.
No, most don't.
I was flabbergasted when I discovered this. Until recently I thought "biodegradable" and "compostable" meant that the item would degrade naturally in the "biosphere". In other words if you put it outside and came back in a decade, it would be mostly gone.
Instead what happened is the plastics industry managed convinced politicians to redefine those terms to mean "will degrade in an industrial composter". Turns out the industrial composter's they had in mind used high temperatures, and a very specific mix of chemicals to break down the plastic. Quoting https://theconversation.com/t-156566 :
> But most certified compostable plastics are only for industrial composts, which reach very high temperatures. This means they’re unlikely to break down sufficiently in home composts. Even those certified as “home compostable” are assessed under perfect lab conditions, which aren’t easily achieved in the backyard.
It appears to me the plastics industry solved the environmental image problem by getting the legal meanings of "compostable" and "biodegradable" redefined to mean "there exists some industrial process converting the material into something biosphere can consume". All they have to do to get earn the right to stamp their products as "biodegradable" is pay some industrial chemists to create an process that transforms their product into something a plant can use.
But as far I can tell it doesn't mean they have to actually do any composting in practice. In fact doing it seems unlikely because there are already lots of very cheap ways to produce compost that don't need an industrial plant or lots of energy (heat). Which they've solved their image problem with a small one off cost - no need for any costly collection or recycling efforts. And no need to actually reduce the environmental impacts of plastic pollution either.
What's reason for that ?
Edit: turns out I was ignorant of how they actually work.
But yes, these don't break down with home composting which is almost always much lower temperature.
From the EPA[0]:
> If a plastic product is labeled “compostable,” can I add it to my home compost pile?
> No. Unless the label indicates that the product is okay for home composting, you should not try to compost it at home. Plastic that is labeled as compostable is generally intended to be sent to an industrial or commercial composting facility which has higher temperatures and different breakdown conditions than those found in a typical homeowner’s compost bin. If your community has a residential compost collection program, check with your local government or recycling company to find out if they will accept compostable plastic under this program.

Perhaps the labeling you saw was intended to be about use, but it looked like it was about disposal?
