ISSUE FOCUS FEED & ADDITIVE MAGAZINE April 2021 51 ECONOMIC AND SUSTAINABILITY BENEFITS OF UTILIZING ADDITIVES DERIVED FROM UPCYCLED FOOD RESIDUES Caproic acid has traditionally been difficult to pur- chase because of fluctuating availability and price lev- el. This unsustainable supply results from the fact that the only industrial source for this acid is palm kernel- or coconut oil, which both contain only 0.3% of this fatty acid. As the ChainCraft upcycling process yields a high level of Caproate (60%) this unique fatty acid salt can now be sourced effectively and at substantial- ly lower cost and stable supply. Butyric acid additives are traditionally derived from petroleum oil and also involve substantial volatility in price and availability, as demonstrated by the impact of the Texas weather and the COVID and Suez-channel related logistic problems on current price levels of this fatty acid. Besides this extreme volatility in pricing and avail- ability, neither petroleum-, palm kernel- nor coconut oil is a sustainable feedstock for fatty acid production. Those fatty acids derived from petroleum oil require high energy consumption and carbon emissions for production of petroleum and the subsequent process- ing into fatty acids. The fatty acids derived from palm kernel- or coconut oil require high carbon emissions for production and their use corresponds to deforesta- tion of valuable rainforest areas. The Caproic and Butyric sodium salts blend pro- duced by ChainCraft with the upcycling of food res- idues by aid of fermentation has a 70% lower carbon footprint and decreases energy use for production by 50% compared to these current processes. More- over, the product helps to reduce the major environ- mental burdens of waste landfilling and -burning and supports a vision of fully circular agriculture. The ChainCraft upcycling process is based on a proprietary fermentation technology developed at Wageningen University in the Netherlands. CONCLUSION Supplementing drinking water with fatty acid salts is an attractive option for boosting welfare and productivity of livestock. The salts are highly wa- ter soluble and by making use of carefully designed blends both gut health and antimicrobial support can be provided in a single step. The ChainCraft proprietary fermentation process for upcycling food residues has proven to yield a blend of Caproic and Butyric sodium salts proficient in boosting produc- tivity of monogastrics. Innovating your drinking water system by implementing this fatty acid salt blend not only offers great benefits to your herd or flock’ health and farm economics, it also helps mak- ing the world a better place. About Jeroen van Dorp Jeroen van Dorp is Business Development Manager at ChainCraft and is expanding the use of novel, sustainable fatty acid based products in a variety of applications within the space of agriculture, food and materials. He holds an MSc with honors in Organic Chemistry and his main focus area is in biobased chemicals, specifically fermentation derived organic acids. Jeroen develops this passion also outside of office hours, as he is an avid micro-brewer and also enjoys other types of home fermentation.
