Bottom view of experimental food digester
Reducing as much of my household waste stream as possible means keeping food scraps out of the trash basket. Our free County-issued compost bins are great for leaves and grass. But, they are not rodent-resistant. Worm bins are one alternative ~ that's an entry for another day. "Food digesters" are another option. I'd read about them, and used a commercially-available one a few years back. Before trying a home-grown option at full-scale, I did what we do with new ideas here in the Division: I began a pilot test.
Last October, my youthful Support Staff helped me drill holes into two buckets: one metal and the other plastic, each with a capacity of about three gallons. We then dug holes, and buried each bucket about 2/3 of the way. This accomplished, we began to add food scraps, including meat. (It's the meat scraps which are especially problematic in a "conventional" compost bin.)
We've been checking on the "digesters" regularly; watch for continued reports of our progress. One of the first things we learned is that the metal can has one big drawback: it rusts. Within days, that lid was rusted shut, only to be removed with great difficulty. Since then, we don't close it tightly, lest it never come off again...
