ISSUE FOCUS FEED & ADDITIVE MAGAZINE January 2025 43 THE CENTRALITY OF DATA IN SUSTAINABLE FORMULATION Reliable data forms the backbone of responsible decision-making. In feed formulation, nutritional composition and cost data are well-documented and relatively accessible. The real challenge emerges when gathering environmental data. Unlike nutrient values, which are often standardized and widely available, environmental metrics vary significantly depending on geographic origin, farming practices, transportation methods, and processing technologies. The environmental footprint of a single ingredient can differ dramatically based on its supply chain. For instance, soy sourced from regions associated with deforestation may have a substantially higher carbon footprint compared to soy grown under more sustainable land-use policies. Without clear, verified information, formulators cannot accurately assess the trade-offs between different ingredients. This lack of consistent data makes it difficult to develop evidence-based strategies that truly minimize environmental impact. LIFE-CYCLE ASSESSMENTS (LCAs) AS A KEY TOOL Life-cycle assessment is a systematic method for evaluating the environmental impacts of a product throughout its entire life cycle—from raw material extraction to end-of-life disposal. In the context of feed formulation, LCAs provide a comprehensive overview of the inputs (land, water, energy), outputs (emissions, effluents), and potential ecological consequences associated with each ingredient. Integrating LCA findings into formulation software helps nutritionists and formulators understand the “big picture” implications of their choices. Instead of relying on incomplete or anecdotal evidence, they can ground their decisions in robust, science-based data. By comparing multiple ingredients through an LCA lens, formulators can identify which options lead to lower greenhouse gas emissions, reduced water use, or less extensive land conversion. Over time, as LCAs become more refined and widely adopted, these insights will drive continuous improvement in feed formulation practices. OVERCOMING DATA CHALLENGES Acquiring reliable environmental data remains one of the greatest obstacles. While some databases and scientific publications provide generic values, these may not reflect local conditions or the unique supply chains of individual feed producers. Methodological differences in how LCAs are conducted can lead to inconsistent results, making it difficult to compare studies. To address this issue, greater transparency and collaboration are needed. Feed companies can partner with universities, research institutions, and certification bodies to develop standardized data-collection methods. Engaging directly with suppliers to verify farming and processing practices can also improve data accuracy. Over time, these efforts contribute to more reliable environmental databases, enabling a more meaningful incorporation of environmental metrics into the formulation process. PARAMETRIC ANALYSIS FOR UNCERTAINTY MANAGEMENT Even with improved data, uncertainties persist. Environmental impact assessments involve assumptions and are influenced by dynamic factors such as market fluctuations, climate variability, and technological advancements. Parametric and sensitivity analyses provide a way to navigate these uncertainties.
