  • Forced Air Vs. Static Pile

    1. 1. Keith Warren 828-230-1729 [email_address] President
    2. 2. Forced Air Composting VS. Traditional Static Pile Composting
    3. 3. The Problem (continued) <ul><li>Farmers have tried static pile composting in the past but with little success </li></ul><ul><li>Reasons why it didn’t work </li></ul><ul><li>Mostly an anaerobic process </li></ul><ul><li>Difficult and time consuming to manage </li></ul><ul><li>Powerful unpleasant odor </li></ul><ul><li>Takes to long to achieve final product </li></ul>
    4. 4. STATIC PILE COMPOSTING… “ BEEN THERE, DONE THAT, NO THANKS” “ Above Ground Rotting chambers”
    5. 5. Forced Aeration vs. Static Pile Comparison <ul><ul><li>Animal Mortality: 240,000lbs/year </li></ul></ul><ul><ul><li>Bin size: 9.5’W x 12.0’L x 5.5’H </li></ul></ul><ul><ul><li>Mortality Capacity/bin: 5,000lbs 3,200lbs </li></ul></ul><ul><ul><li>Cycle Time 1 st Stage: 45 days 120 days </li></ul></ul><ul><ul><li>Cycle Time 2 nd Stage: 45 days 120 days </li></ul></ul><ul><ul><li>Cycle Time 3 rd Stage: 0 days 60 days </li></ul></ul><ul><ul><li># of 1 st Stage Bins: 8 bins 18 bins </li></ul></ul><ul><ul><li># of 2 nd Stage Bins : 4 bins 16 bins </li></ul></ul><ul><ul><li># of 3 rd Stage Bins: dry stack + 14 bins -------------------------------------------------------------- </li></ul></ul><ul><ul><li>Total Number of Bins: 12 bins 48 bins </li></ul></ul>Forced Air Static Pile
    6. 6. ADVANTAGES OF FORCED AERATION OVER STATIC PILE <ul><li>NO FUEL EVER NEEDED </li></ul><ul><li>CONTINUOUS AERATION </li></ul><ul><li>NO TURNING REQUIRED TO AERATE </li></ul><ul><li>LEACHATE CAPTURED & RECYCLED </li></ul><ul><li>TEMPS ABOVE 150 °F for 10+ DAYS </li></ul><ul><li>SUPERIOR PATHOGEN KILL </li></ul><ul><li>HALF THE STRUCTURE REQUIRED </li></ul><ul><li>HALF THE PROCESS TIME REQUIRED </li></ul><ul><li>CONCRETE BIN DESIGN FOR DURABILITY </li></ul><ul><li>NONE OF THE MESS, SMELL, DREAD… </li></ul>
    7. 7. <ul><li>Advantages (Continued) </li></ul><ul><li>Very Little Odor </li></ul><ul><li>Viable Product Produced </li></ul><ul><li>Composting process accelerated with forced aeration (75% after 3 wks.) </li></ul><ul><li>Employee satisfaction </li></ul><ul><li>Utilizes Coastal Bermuda grass, corn and soy bean stubble </li></ul><ul><li>$150.00 Utility costs/month </li></ul>
    8. 8. Competitive Analysis
