Evonik's amino acids support animal nutrition, protect environment

 
 

Evonik's recent comparative life cycle assessment (LCA) had affirmed the positive environmental effects of its amino acids in animal feed.

 

According to the company, farmers who use Evonik's amino acids on poultry or pig feed not only ensure proper animal nutrition, but also help to protect resources and the environment.

 

The conclusion, presented by the Animal Nutrition Business Line, was drawn from an LCA which was certified by German standardisation body, TÜV Rheinland.

 

Evonik had conducted such assessments on its products, namely, MetAMINO®, Biolys®, ThreAMINO®, TrypAMINO® and L-Valine, for comparison with alternative raw materials such as soymeal or rapeseed.

 

LCAs record and evaluate environmental impacts along with energy and raw materials consumption over the entire lifecycle, ranging from the extraction of raw materials to the production of amino acids and the agricultural use of the animals' manure. Since the first LCA for DL-Methionine in 2002, the data has been continually updated and expanded to include all five essential amino acids (DL-Methionine, L-Lysine, L-Threonin, L-Tryptophan and L-Valine) for animal nutrition by Evonik.

 

"The certificate by TÜV Rheinland is further proof of our effort to carefully evaluate all environmental impacts without bias, including with consideration for new products," said Dr. Thomas Kaufmann, the senior vice-president for sustainability development of nutrition and care. "The results are unequivocal; adding our amino acids to animal feed, combined with the associated consistent decrease of raw protein in the feed, is an extremely sustainable method to ensure healthy animal nutrition while providing eggs and meat to a growing world population and leaving minimal traces in the environment."

 

If an amino acid mixture is added to feed instead of supplementary soy or rapeseed, the greenhouse effect in poultry farming will decrease by a factor of 27, Evonik explained. In pig farming, the reduction factor is an acceptable factor of 13. Over-fertilisation potential is decreased by a factor of 39 for poultry and 16 for pigs. The effect on acidification potential was determined as a factor of 35 for poultry farming and 19 for pig farming.

 

These effects were induced as the amino acids utilise domestic wheat rather than imported soy seed as a source of nutrition. This in turn eliminates the energy-intensive processing of soybeans as well as imports from main producing countries including the US, Brazil and Argentina. In these regions, crops consume increasing amounts of farmland, frequently leading to the destruction of rainforest as a result.

 

These aspects of environmental policy will gain more significance in future, considering that the world population has already reached seven billion people, Evonik said. The FAO (Food and Agriculture Organization), as well as WHO (World Health Organization), projected that the global meat consumption will increase from the current 41.3 kg per capita to 45.3 kg per capita in 2030. In Evonik's view, the trend emphasises a bigger priority on effective and resource-efficient productions within small areas of farmland.

 

"Sustainable nutrition for the growing world population means that we must use the existing resources with the greatest efficiency," Kaufmann said. "Our certified comparative LCA is proof that our amino acids are making an important contribution. At the same time, we create transparency so that customers can see exactly how the purchased products affect the environment."

 

Evonik is the only company in the world that produces and markets all four essential amino acids used in advanced animal nutrition, specifically, MetAMINO® (DL-methionine), Biolys® (L-lysine source), ThreAMINO® (L-threonine) and TrypAMINO® (L-tryptophan). Mepron®, a rumen-stable DL-methionine for high-performance dairy cows, and CreAMINO®, a creatine source for broilers, complement Evonik's product portfolio.
