Chapter 17 - Rendering

The rendering option allows removal of carcasses from the farm and eliminates environmental pollution possibilities while recycling a troublesome waste material into a good feed ingredient. Renderers have been cooking, hydrolyzing and pressing processing plant wastes into by-product meal, feather meal and fat for years. The three major concerns related to this method of disposal are biosecurity, proper feather breakdown and a suitable on-farm storage method to reduce transportation cost.

The following are Best Management Practices (BMP) to be implemented for storing poultry destined for a rendering plant.

• Dead poultry must be held in a leak-proof container.
• Dead poultry not to be treated by refrigeration, fermentation, or acid preservation, must be delivered to, or be picked up by, a rendering company within 24 hours of death.
