Description:
Egg breaking plants yield an estimated 50,000 tons of waste annually. These wastes are commonly disposed of on land. This method of disposal is becoming more difficult due to the potential for pollution of local water resources. A triple pass rotary drum dehydrator was installed at an egg breaking plant. With appropriate engineering modifications a system for producing egg shell meal from the total egg shell waste from the breaking plant was developed. This meal was utilized as a feedstuff by a local mill and incorporated into a layer diet. This diet was fed to several commercial flocks of cage layers. Appropriate data were collected to determine meal production costs, yield of meal, feed produced, feeding data, and layer flock performance. COD and BOD data were generated to determine the pollution potential of the waste were it not converted to a useful by-product.
