DESCRIPTION
http://www.extension.org/67567 Composting is becoming widely accepted as a best management practice for equine facilities. Stable waste is a readily compostable feedstock which generates heat and transforms into a finished compost product in as little as 2 weeks using in-vessel technologies. Composting the stable waste is financially beneficial, turning a liability into an asset, negating disposal fees, offering a decrease in bedding expenses and creating a saleable product. In- vessel composting allows for compliance with increasing environmental regulations associated with manure management. The primary topic will be the cost analysis of in-vessel vs. open pile composting of stable waste. The author will also compare the value of the product produced, specifically the value added with weed seed kill, reduction of pathogens, and the uniform quality and dryness of end product. The presenter will provide lab data showing compost stability and pathogen reduction using both shavings and pellet bedding. Value of the end product is seen in bedding re-use and/or soil amendment. Discussion of cost savings will differ for different venues in the industry. Case studies will be shown for the financial analysis of a private 20 horse stable and the 65 horse stable at the US Army base at Fort Myer/Henderson Hall in Washington DC.

Cons of Bin System• 90-180 days• Labor to turn piles• Temperature issues on

Pros of Bin System• Affordable
Pros of In Vessel System• 10-20 days• Automated Auger• Uniform Temperature• Odor Control
Cons of In Vessel System• Cost
