The NatureMill line was invented by Russ Cohn to solve some of the unfortunate odor problems that curbside composting created near his home in San Francisco. They are the most popular brand of kitchen composters in the US and earnest proponents of composting as a way to reduce our environmental impacts.


The plastic body and components are made from 100% recycled plastic.

Energy Efficiency

NatureMill's quick and hot method of composting can process a whole array of foods into compost, but it also requires electricity, which usually uses fossil fuels. The NatureMill will use about 50 kWh a year which emits an estimated 100 lbs CO2. Since we expect to save up to 500 lbs of CO2 a year by composting all kitchen waste, so it's well worth a little electricity to make composting easy.


The entire unit can be recycled where facilities exist. Most municipal recyclers will accept the materials if they are dissembled and properly sorted.

Staff Pick

There is a lot buzz about this composter in green communities – and for good reason. Hot composting is the only way to safely process grains, diary, meat, and pet waste to make garden compost. We love that we can throw almost anything into it and get fresh, safe, and clean compost in just two weeks!

*These estimates for carbon savings were derived from a number of sources. The EPA's EPA's WARM Model provides estimates of GHG avoidance from composting versus landfilling. The EPA's 2012 Municipal Waste Report provides estimates for non-recovered food and yard waste volumes in the US. The EPA also estimates the typical US carbon footprints and population data was available from the US Census Bureau.
