Semi food related...
I've been composting for two years now, dropping off in Cambridge either at the drop off center or the Whole Foods on Prospect. This is made MUCH easier using compostable bin liners like the ones made by Bio-bag. I used to buy them at WF, but they don't seem to carry them anymore- they have the giant lawn leaf bags and the dog waste bags, but not the compost bin size.
Anyone out there have a good source for these bags locally? I can order them from amazon, but it seems a bit silly...
I can't answer your post about where to get the bags but I can say that they don't compost fully. I gave up using them a long time ago as they don't completely breakdown. I was pulling them out of my compost pile for a whole year afterwards.....sorry!
Maybe in a commercial facility they breakdown but not in a home composter.
Since I live in a condo, I drop my compost off at the Cambridge DPW pickup or at the WF pickup which both go to a commercial composter. They can take a lot of stuff that you wouldn't do at home (bones, mussel shells, paper towels, so I think they can do the bags just fine.
If I weren't having to carry it (on my bike) a mile, and was just walking out to a compost bin, I'd just use the bin without a liner, but the bin is tough to carry on my bike, and the bags make a huge difference.
