Not that I doubted you at all, I just wanted to get a bit more detail. The whole article is rather interesting in how we’ve used CA as a society and what happens to it. In some cases, according to the above, the product can be biodegraded using cellulaise and exposure to 280nm or smaller wavelengths of light to promote the process; the cellulaise is only present in very bio-active soil, which isn’t common in places where smokers will be tossing their butts, the filter is usually protected by paper wrap, so even sitting in the open where it can be bombarded with direct sunlight, there’s going to be a significant delay before any UV can reach the CA in the filter.
I’m extrapolating from the Wikipedia article for that last bit… but it’s logically sound. Between the difficulty of UV reaching the CA, plus the absence of any additional substances to aid in the degradation of the CA, it would take substantial time to degrade. Though it’s derived from either cotton or wood cellulose.
It’s fascinating stuff.
I’ve never regularly smoked cigarettes, and I’ve always had an issue with people just flicking their butts wherever they want. Now I have scientific information to support that discomfort, so thanks
A reminder: the filters are basically plastic and will last forever.
Say what you want about the rest, it’s filters which bother me the most.
up to 10 years or so, actually --> https://www.sciencelearn.org.nz/resources/1543-measuring-biodegradability
not sure about glass - obsidian is basically glass and it lasts a lot longer than that.
Not sure about that list - they don’t “biodegrade”, but they do break down into microplastics, our favourite size of plastic these days.
eh, i prefer the nanoplastics - microplastics make my cells feel funny
I thought they were cotton. TIL.
Cellulose acetate. Yeah.
Interesting.

See, that’s exactly why I don’t use an Ash tray or a bin.
I don’t throw it on the ground either. I just swallow it. There is no need to worry about littering or finding somewhere for it that way.
