The Green Cone food waste digester was invented in the 1970s in northern Ontario. The Green Cone accepts all kitchen waste, cooked and raw,  it will dispose of meat products, dairy products, and even bones. This device is not designed to produce compost for use in the garden, it is designed to turn kitchen waste into water, carbon dioxide, and just a little bit of humus, and it does so without turning or emptying. The Green Cone is designed to digest kitchen garbage through the winter as well as in the summer. It needs sunlight and adequate drainage.

The Green Cone has four parts. First there is a round black plastic basket, looking just like a laundry basket. This basket is 21 inches wide and 17 inches deep, and is buried into the ground so its top is just level with the surface of the soil. Next comes a black cone that attaches to the top of the basket. Over the black cone is a green cone that also attaches to the top of the basket but creates a 4/5-inch space between it and the black cone. Finally, there is a tight-fitting cover for over the green cone. The Green Cone sits 26-28 inches above the ground.

When the sun is out, the air between the black cone and the Green Cone is heated sufficiently to create air circulation over and around the kitchen garbage, creating a fertile environment for the microbial population. The Green Cone takes about three years before enough humus accumulates and requires you to take the device apart and dump the black stuff out of the bottom basket. It doesn't smell. It doesn't attract insects or pest animals. For winter, there is a powder that contains additional microbes that is sprinkled inside the cone about once a week to keep the system cooking. That is not needed in the spring, summer and fall.
