This document compares forced air composting to traditional static pile composting. Forced air composting uses fewer bins, has shorter cycle times, produces less odor, and results in a viable compost product faster than static pile composting. Some advantages of forced air composting are that it requires no fuel, allows continuous aeration without turning, captures and recycles leachate, reaches temperatures over 150 degrees Fahrenheit, requires half the structure and processing time, and produces much less mess and odor than static pile composting.

2. Forced Air Composting VS. Traditional Static Pile Composting

3. The Problem (continued) Farmers have tried static pile composting in the past but with little success Reasons why it didn’t work Mostly an anaerobic process Difficult and time consuming to manage Powerful unpleasant odor Takes to long to achieve final product

4. STATIC PILE COMPOSTING… “ BEEN THERE, DONE THAT, NO THANKS” “ Above Ground Rotting chambers”

5. Forced Aeration vs. Static Pile Comparison Animal Mortality: 240,000lbs/year Bin size: 9.5’W x 12.0’L x 5.5’H Mortality Capacity/bin: 5,000lbs 3,200lbs Cycle Time 1 st Stage: 45 days 120 days Cycle Time 2 nd Stage: 45 days 120 days Cycle Time 3 rd Stage: 0 days 60 days # of 1 st Stage Bins: 8 bins 18 bins # of 2 nd Stage Bins : 4 bins 16 bins # of 3 rd Stage Bins: dry stack + 14 bins -------------------------------------------------------------- Total Number of Bins: 12 bins 48 bins Forced Air Static Pile

6. ADVANTAGES OF FORCED AERATION OVER STATIC PILE NO FUEL EVER NEEDED CONTINUOUS AERATION NO TURNING REQUIRED TO AERATE LEACHATE CAPTURED & RECYCLED TEMPS ABOVE 150 °F for 10+ DAYS SUPERIOR PATHOGEN KILL HALF THE STRUCTURE REQUIRED HALF THE PROCESS TIME REQUIRED CONCRETE BIN DESIGN FOR DURABILITY NONE OF THE MESS, SMELL, DREAD…

7. Advantages (Continued) Very Little Odor Viable Product Produced Composting process accelerated with forced aeration (75% after 3 wks.) Employee satisfaction Utilizes Coastal Bermuda grass, corn and soy bean stubble $150.00 Utility costs/month
