So when I started this, I made a blanket statement that I was giving up all single use plastics. Over the course of this project however, there have been a few times when I have been surprised by receiving something from what I thought was a plastic free and sustainable company that appeared to be plastic. This happened again yesterday. I got my new toothpaste tablets and along with them, also purchased floss that is made out of silk as well as one other toothpaste that comes in a glass container but doesn’t have fluoride (figured I try this to compare with the Dent tabs).

This came with one refill which was wrapped in what appeared to be a clear plastic bag.

This infuriated me. If you can’t purchase what is specifically supposed to be a non-plastic alternative from a vendor called lifewithoutplastic.com, then how is this even feasible. I was getting ready to write an angry email when I started reading the packaging. Turns out this “plastic bag” is “compostable.”
This was something that I felt the need to dive into. After doing some research across a variety of websites, here are some main takeaways I have found:
- Composting is hugely important. Every time we put food scraps into the garbage, they end up in landfills where the release methane under those conditions. Methane is about 30 times worse as a greenhouse gas than C02.
- These “bioplastics” are largely made from cornstarch. While they do potentially allow for a good path forward to transition out of single use plastics, at some point, the amount of corn grown to support this won’t be sustainable and we will need to find non-plastic alternatives.
- The comments section of a couple of articles on this discuss the merits of how much fossil fuel is needed to create these bioplastics vs. regular plastics. I haven’t had time to research this yet but am unconvinced that the manufacturing process of these compostable plastics is better for the environment that regular plastic.
- While some of these bioplastics can be composted at home, the vast majority need to be composted at industrial facilities. It’s really difficult to determine how many of these industrial composting facilities there are near me, let alone in the U.S. but it seems to be a number that is on the order of about 200 across the entire country.
- It is not easy to find these industrial composting facilities let alone get bioplastics to them. It took a lot of effort and after about an hour of internet searching, I found two facilities near me that may support this. I had to email these companies to learn more so still don’t have an answer.
- If these bioplastics end up in landfills, they either will not break down under those conditions and last just as long as regular plastics or will break down into methane. Given the difficulty of finding a place to compost these plastics, the odds of them ending up in an industrial compost facility and not in a landfill or recycling center seem really low and therefore, will continue to contribute to the problem.
So where does that leave me? I think I need to do some more research into where I can properly dispose of these bioplastics before I feel comfortable knowing that they will end up being composted. If they are the only option for something that is irreplaceable, then I think it will be ok to use them. If not, I may try to avoid these as well as they are still contributing to a wasteful lifestyle that is unnecessary. This will probably be something that falls under the eye test for me. For now, this probably looks something like a yes to floss and a no to takeout containers.
The packaging on the floss box did lead me to one more sad discovery. It went out of its way to point out that it was printed with soy based inks.

Apparently toner is usually made up of finely ground polyester. This means that every time I get something printed, I am receiving a single use plastic. I need to pontificate on this another day because I haven’t figured out what, if anything, I can do about this yet. A problem for another day I guess.
