Technical-grade fatty acids are characterized by their high free fatty acid content and suitability for direct transesterification into biodiesel. They originate from palm, tallow, or mixed vegetable/animal oil refining and provide a cost-effective route to renewable fuel production.
Fatty acids for biofuel are free fatty acid streams derived from fat splitting, distillation, or refining. They are a direct feedstock for FAME and HVO production.
