Excerpt from The Poultry Processing Industry: A Study of the Impact of Water Pollution Control Costs

Large capital investments needed to construct and operate the best available control technology to meet increasingly stringent effluent limitations might force the poultry pro cessing industry - which Operates on a narrow profit margin - to seek lower cost alternatives.

The method of handling poultry byproducts - blood, offal, and feathers-generally determines the pollution potential from slaughtering operations. Current industry performance in by product handling and disposition is much better than 15 years ago. If practices of the earlier period were followed to the same degree today, pollution potentials of the industry would be greater.

Of the 386 poultry slaughtering plants responding to the 1971 usda survey, 245 had final municipal waste treatment, 113 had private treatment, and 28 had no treatment. Plants with final municipal treatment accounted for about 65 percent of Federally inspected poultry slaughter; plants with private treatment, 25 percent; and those with no treatment, 6 percent.

The surveyed plants currently have an estimated investment in private wastewater treatment facilities of to million. Average replacement value ranges from to per plant with private treatment. Estimated operating and maintenance costs - including capital costs - range from to cents per 100 pounds of live weight slaughter. Current wastewater treatment costs range from to percent of total costs for representative plants.

Sixteen plants with only primary treatment and 28 with no treatment would need to million - an average cost per plant of to - to upgrade wastewater treatment to the best practicable control technology (anaerobic - aerobic lagoon system). With this investment, the 141 plants with private treatment-97 currently with the equivalent of the best practicable control technology, 16 with only primary treatment, and 28 with no treatment - could likely meet effluent limitations of the best practicable control technology.

The 141 plants, including eight that currently have extended aeration, would require a total investment of $21 to $60 million to upgrade to the best available control technology (extended aeration) - an average investment per plant of to Operating and maintenance costs would range from to cents per 100 pounds live weight slaughter - representing to percent of total costs for representative plants.
