  1. Waste Systems Overview for Swine Production Robert T. Burns, PhD. PE Professor & Assistant Dean University of Tennessee

  2. Lesson Objectives • Become familiar with animal production systems and associated waste management systems used in the US • Understand how production system decisions impact the selection and operation of waste management systems.

  3. ANIMAL WASTE MANAGEMENT SYSTEM FUNCTIONS COLLECTION - Initial gathering of waste from animal confinement area TRANSPORT - Movement of waste after collection STORAGE - Containment until treatment or utilization PROCESSING - Solids Separation, Moisture Adjustment TREATMENT - Anaerobic, Aerobic UTILIZATION - Land Application, Feeding

  4. Animal Waste Management System Storage Collection Treatment Application / Utilization

  5. WASTE HANDLING OPTIONS SOLID Moisture < 70 % to handle mechanically LIQUID Moisture > 90 % to handle hydraulically

  6. Manure “as excreted” cannot be effectively handled as a solid or liquid.

  7. Liquid Standard Irrigation Equipment 100 % 96 % 90 % 90 % Manure Pumping Equipment Semi-Solid Slurry 80 % 70 % 70 % Can Handle as a Solid, depending on type of bedding added. 60 % % Water 50 % 40 % 30 % 20 % 10 % 0 % Solid
