Abstract: Two automated systems were designed, developed, and commercially tested to accumulate blood in troughs and basins and to transport the blood (system A) and the blood and lungs (system B) through pneumatic tubes. System A picks up blood at predetermined intervals, deposits it in a holding tank, and eventually moves it into a transport truck to be hauled to a rendering plant. System B also accumulates blood and picks it up at frequent intervals. In addition, it picks up accumulated lungs, mixes them with the blood, and feeds this material into an onsite continuous rendering operation. Both systems are highly effective and reliable in handling the product and greatly reduce the pollution entering the plant effluent. After the installation of system B, total effluent pollution was reduced in a poultry processing and rendering plant by: BOD (biochemical oxygen demand), 44%; fat, 26%; and suspended solids, 24%.
