This digester is basically a compost bin with a twist. The twist being that the bin is sealed and partially buried to deter pests from feasting on the stuff inside.
I do not plan to harvest any material from the digester since my compost bin provides enough humus for my soil-building needs. The other reason for not harvesting the digester's contents is that it will be comprised of some nasty stuff, namely dog poop and rotting meat. Yechh!
My inspiration for the project came from the website of my local government: http://www.compost.bc.ca/learn/factsheets/3digester.pdf
Let's get started!
Step 1: Items You Will Need...
- Electric drill
- Holesaw kit
- Felt-tip marker
Step 2: Siting the Digester
Once you have found a good spot for your digester it is time to dig a hole. I made the hole slightly larger than the bin and about 8 inches deep. I'm sure it wouldn't hurt to go a bit deeper.
Step 3: Preparing the Bin
I used a 1-3/4" holesaw to make the holes. The molded supports on the bottom of my bin made it very easy to lay out my holes as you can see in the photo. You may have to use a different method to space your holes. Just make sure you leave enough material between the holes so as not to compromise the structure too much.
After you have drilled all the holes in the bottom, drill a series of holes around the lower circumference of the bin. Again I used the molded supports as reference lines to get the appropriate spacing.
Step 4: You're Almost Done!
Thanks for reading and good luck with your digester (if you make one - post some photos or comments!)
