COMPARED OPERATING COSTS • WINDROW COMPOSTING • HIGHER LABOR COSTS • FREQUENT TURNING OF ROWS • FREQUENT WATERING IN WARM WEATHER • ROWS CAN BECOME SATURATED • ODORS CAN BE OFFENSIVE • GREATER SPACE REQUIREMENTS • RESIDUAL WATER MUST BE TREATED AND COLLECTED • MUST REACH 131o F FOR 15 DAYS REQUIRING CONSTANT MONITORING

  7. COMPARED OPERATING COSTS • AG BAG COMPOSTING • LESS LABOR COSTS (TURNING & WATERING) • PATHOGEN REDUCTION PERIOD IS LESS (3 DAYS AT 131o F) • ODORS ARE LESS SIGNIFICANT • BETTER UTILIZATION OF SPACE • BAGGING MACHINE COST $110,000 • BAGS COST $1300 EACH (USED ONCE)
