It looks like it might be a landslide in Heidi Tolliver-Nigro‘s compostable packaging test between Boulder Canyon and SunChips. Find out who’s in the lead:
The decaying grass in my compost pile is getting heavier, the pile of eggshells and other kitchen scraps on top is getting heavier, and the mass is getting stinkier. Underneath are Boulder Canyon and SunChips chip bags, both of which claim to be 100% compostable.
The Boulder Canyon bag is soft, quiet, and made of wood fiber. The SunChips bag is loud and crackly and made of “vegetable-based” material. Both are deteriorating at clearly different rates.
Judging from the look of things, however, I might not have to continue the experiment much longer. There is absolutely no indication of decay on the SunChips bag. It looks as crisp and intact as the Doritos bag below it. The wood fiber-based Boulder Canyon bag, however, is barely recognizable as a chip bag at all. Not only has it lots most of its ink, but not visible in the picture is that it’s lost all of its structure. It’s thin, with no body whatsoever, and appears ready to fall completely apart.
This is after only four weeks in an unattended, unturned compost heap.
SunChips claims that its bag will decompose fully in a “hot, active compost pile” in 14 weeks. Granted, it’s only been four weeks and my compost pile isn’t exactly turned on a regular basis, but with the rapid decay of the Boulder Canyon bag, the SunChips bag better get crackin’. It’s falling way behind.
