International media June 24, 2015, Evonik's new comparative life cycle assessment says that amino acids in animal feed can have a positive impact on the environment.
Farmers who add Evonik Group amino acids to poultry and pig feed have guaranteed animal nutrition and helped protect resources and the environment. This is the conclusion of the Economist Animal Nutrition Business Unit in a comparative life cycle assessment that has been confirmed by the German standards body, TüV Rheinland.
Evonik is the only animal feed amino acid producer that compares its products with alternative raw materials such as soybean meal or rapeseed for life cycle assessment. The life cycle assessment records and evaluates the environmental impact of the product throughout its life cycle (from the extraction of raw materials to the production of amino acids and animal waste) and the consumption of energy and raw materials. Since the first life cycle assessment of DL-methionine in 2002, the evaluation data has been continuously updated, and currently includes all five animal essential amino acids (DL-methionine, L-lysine, L) from Evonik Group. - threonine, L-tryptophan and L-valine).
Dr. Thomas Kaufmann, Senior Vice President, Nutrition and Nursing Sustainability, Evonik Group, said: “The results of the analysis are very clear – adding our amino acids to animal feed, combined with a corresponding reduction in the crude protein content of the feed, which It is a highly sustainable method of ensuring animal nutrition while providing eggs and meat to a growing world population, and has minimal environmental impact.â€
If an amino acid mixture is used in the feed instead of supplemental soybean or rapeseed, the greenhouse effect reduction factor for poultry farming can reach 27. In pig farming, the reduction factor of the greenhouse effect can also reach 13. The probability of excessive fertilization in the poultry farming industry has decreased by 39, and the probability of excessive fertilization in the pig farming industry has decreased by 16. In addition, the use of amino acids also has an impact on the acidification potential.
The reason for these effects is that the amino acids added to the feed use domestically produced wheat rather than imported soybeans. This in turn eliminates the need for energy-intensive processing of soybeans and imports of products from major producers such as Brazil and Argentina, where crop cultivation takes up more and more farmland and frequently causes damage to the rainforest.
Since the current world population has reached 7 billion, these aspects of environmental policy are even more significant in the future. According to estimates by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO), global meat consumption per capita will increase from the current 41.3 kg/person to 45.3 kg/person by 2030. This will put more efficient and resource-efficient production on a small area of ​​farmland in a more prominent position.
