Financial Benefits of Composting for the Equine Industry

3,053 views

Published on

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.

  • How you take a liability and turn it to a financial gain
  • Discuss the benefits of an in vessel system vs a pile or bin system. Comes down to assurance in the quality of compost produced
  • Speedvs Area explained. IN vessel in 14-21 days vs up to one year. Ask Caitlin – lab data.
  • Trending graph shavings, pellets affecting market. Expense of wood material increasing due to petroleum prices – burn pellets for heat and delivery fee. Low new housing market. General trend washington – 18-20% logs in Washington exported as logs – no milling here. Largest supplier of shavings to US is Canada. Shavings not valuable for paper market because fiber is too short. Pellet market direct competition with shavings. Run through auger and extrude it with a binding agent. Pellet production is high energy process. Also bags add to waste stream. Pope and Talbot, Weyerhauser becoming land manamgement companies with land ! Asset not t
