Some Updates on the search for the best drum composter.
DIY insulated drum composter with a hand crank.
One of the things I have been involved with this year is teaching classes in how to make “hot” compost. A hot compost pile is one which is constructed to create the ideal environment for thermophilic bcteria which can break down organic material is as little as one month.
The downside to hot composting is that in order for the thermophilic bacteria to thrive, they need an oxygen rich environment. Normally this means you must turn your pile… a lot.
Wet steamy compost is very heavy. Thus, after several bouts of sore muscles, and even tendonitis, I began to think of ways in which oxygen could be introduced with as little physical labor as possible.
This is my first attempt at a solution: A drum composter that sits on the ground and is simply rolled along. Tumbling the drum, turns the pile and aerates the compost. Voilá! Better faster compost with less work.
