In the processing of poultry for the production of prepared foods such as soups and frozen dinners, waste-water is generated containing significant quantities of fats, protein and starchy materials. These materials must be removed from the wastewater before it is discharged. Typical recovery consists of removing the solids through a combination of dissolved air flotation and filtration. The solids can then be rendered and utilized as poultry feed. This paper investigates an alternative to traditional processing in biologically producing valuable single cell protein from poultry processing waste. The results of fermentation experiments to produce single cell protein by both direct and indirect routes are presented.
