ISSUE FOCUS FEED & ADDITIVE MAGAZINE December 2023 43 sure that the assessment procedures utilized in the preparation of the LCA comply with the guidelines highlighted above. To provide producers with the most accurate picture of those ingredients, additives, practices (models), etc. for inclusion within their operations, companies must be able to present an independently verified LCA confirming the value of their product / service to assist with the reduction of CO2eq emissions. DEFINING YOUR FOOTPRINT An important part of the requirement highlighted above is the growing need for premixers and feed millers to provide a LCA verified CO2eq value for each feed / premix blend they are manufacturing (expressed as Mt of CO2eq per Mt of finished product). This value can then be captured by their customers who are in turn working to evaluate the total carbon emissions of their livestock operation. Having this value in hand allows nutritionists and manufacturers to effectively evaluate the individual CO2eq impact of various ingredients / additives being added to the blend, with the objective of lowering the blend’s total CO2eq, while maintaining its nutritional requirements. SOLVING THE CARBON FOOTPRINT CHALLENGE Solving the carbon footprint challenge will require the combined use of multiple feed additives, alternative ingredients and practices that must be verified via an independent LCA review. Establishing a LCA value for individual additives, ingredients, practices, etc. can become a valuable input when assessing the total CO2eq footprint that exists between different formulations and manufacturing processes. SELKO INTELLIBOND®: FIRST TRACE MINERAL WITH A VALIDATED LCA To assist with this growing need Selko® has completed an independently reviewed LCA, which identifies the total carbon footprint of individual Selko IntelliBond® products (See Table 1). Selko IntelliBond® is the first family of improved trace mineral nutrition products to provide the livestock industry with a verified LCA for this purpose. The values presented in Table 1 are specific to the highly efficient Selko IntelliBond® manufacturing process and will be of value to feed compounders and premixer that are working to reduce their products’ carbon footprint.
