The Naturemill composter can eat through 4 pounds of organic waste per day, is the size of a small garbage pail and makes a nice batch of high-nitrogen compost every 2 weeks. The enclosed design pumps fresh air into a basket containing the waste while automatically rotating it at pre-set intervals and maintaining a temperature of 140 degrees resulting in odor-free composting happening right under the kitchen sink.
President of Naturemill, Russ Cohn, says in an interview that due to the natural microorganisms already in most foods the Naturemill doesn’t require activators but you will have to change the filter on the air filtration system roughly once per year, depending on actual usage. This will cost around $1 dollars if you are willing to change the carbon in the filters yourself or you can by replacement filters from Naturemill. Other than that, operating the composter requires emptying the catch basin of water if you are putting in really wet waste and taking out your natural fertilizer when the indicator light indicates there is a finished batch. It costs between $300 - $400 and you can buy it online.
