Intertek laboratory services evaluate biodiesel feedstock materials, and measures the quality and suitability of raw feedstock materials for the production of biodiesel fuel. Using AOCS test methods, the biodiesel laboratories analyze edible oils, animal fats, recycled vegetable oils and other potential biodiesel feedstocks for contamination, byproducts, intermediate products and other factors that could impact engine performance. AOCS test methods for fats, oil and grease quality are useful in determing the quality of potential biodiesel production feedstocks.
