A new publication about Phosphorus derived from animal by-products is now available on this site.
Phosphorus is an important nutrient for both plant and animal growth. In human and animal bones, Phosphorus is present in large quantities, it is also found in smaller quantities throughout the body and is critical for various cellular functions including as a component of DNA.
Rock phosphate is the mineral form of Phosphorus, it is mined and processed into fertilisers and feed supplements as well as being used in a wide range of other industrial applications. Phosphorus from food grade sources is reused as a high value feed ingredient or fertiliser.
It is predicted that rock phosphate production will decline significantly later this century.
Food grade bones are normally processed to extract gelatin – an important ingredient for the food and pharmaceutical industry. Crushed bones are degreased then demineralised with diluted hydrochloric acid before the calcium-phosphate is precipitated. The end product is a compound rich in Phosphorus and Calcium and suitable for use in feed stuffs for pets, poultry, pigs and aquafeed.
