All of the cow manure on our farm passes through a methane digester. The methane gas is captured and burned as a biogas to heat hot water for the farm and residence. As the manure exits the methane digester it is separated, solids from solids from liquids.
Separated liquids are stored in the farm’s 800,000 gallon lined lagoon until it is time to fertilize the crop fields. Because it is a liquid, we are able to pump and irrigate the manure, rather than driving back and forth from farm to field with tractors, saving on diesel and using less fuel.
Separated solids are composted and used both as bedding for the cows and in the production of CowPots. To date, tens of millions of CowPots have been formed and shipped nationally and internationally. Through the sale of this value added product, we have reduced our farm’s carbon footprint while providing an alternative to peat and plastic for gardeners and growers.
We say that CowPots are recycled because we are harvesting energy from the manure before it is used for fertilizer and formed into CowPots.
