When You Think About It, EVERYTHING is Compostable, in Geologic Time...

Hard-core longtime readers with uncluttered lives may remember my 2009 post about finding an allegedly "100% Compostable" drinking cup in my compost heap, clearly uncomposted, 15 months later.  It looked like this:



After writing that post, I threw the cup back into the compost, along with another cup of the same make that I had found.  And, since we use a two-heap yearly-rotation sort of composting system, there they sat, quickly forgotten, over the last 17 months.  Until last weekend, when I cast my spade into the rich, dark earth that had alchemically manifested out of what had once been yard and table scraps:



Seriously, isn't composting bizarre?  Who would think it would work?

But anyway, you already know what's coming.  As I shoveled, I heard the sharp crack of brittle plastic and, well, here's the original cup, after three years of composting:



And here's cup #2, after a year and a half.


So honestly, I'm a little disappointed with the "Greenware" people.  I'm looking forward to the improved 200% compostable product.

That's hilarious.
I bet it would rot in Arkansas!
I use the paper from the shredder in our composter, and there are always little sparkly chips of plastic/mylar that persist....

I went to a Bar Mitzvah about a year ago & in attendance was a guy who sells "containers." I asked him about this based on your last years reveal & disappointment...

This is the gist of what he said:

Bio-based plastics are often touted as “biodegradable.” But this term has several stipulations behind it. While these products may in fact have components that are capable of degrading, this process only occurs under specific conditions and biodegradable plastics cannot be composted in a backyard compost pile. Because the material requires very high heat, these plastics can only degrade in a commercial composting facility.

You know, I'm OK that our household's capacity for degradation isn't up to commercial standards.

mrs.5000 for the win!

Yes, Calico, these plastics can only degrade in a commercial composting facility. Call me crazy, but I find this a rather fanciful definition of "100% Compostable."

I think you should write a sharply worded letter to the Greenware people. Or to the news. I'm actually serious about this, all the vendors at the farmers market & saturday market are switching to 'compostable' products... but if they don't actually compost, what's the point??? It's a rip off.

This got me googling and I ran across a discussion of the difference in perception between what consumers think compostable and biodegradable mean, vs what companies mean when they use those terms. Have you ever heard of BPI? Supposedly items that carry their logo should be compostable in the manner that consumers expect.

Some people have called my blog a compost heap of useless crappola, and I resent that.

Jenners said...

I guess I have an uncluttered life/mind as I do clearly remember this cup. It pisses me off that it is a blatant lie. Clearly, the cup does not decompose naturally.

Aviatrix said...

That should be illegal. There's pretty much nothing that can't be degraded given "specific conditions." "Oh yes, this is fully biodegradable, provided you cast it into the sun."

If you'd had an equal quantity of plutonium on your compost heap it would be more degraded than that.
