Turning Grease & Byproducts into Biodiesel By James Davis Biodiesel is a clean-burning alternative fuel that is produced from renewable resources, including animal byproducts and grease. In this blog, we will explore the process of how these materials are transformed into biodiesel. The first step in the production of biodiesel is the collection of grease and animal byproducts. These materials are typically obtained from sources such as slaughterhouses, grease traps, and rendering plants. The grease and animal byproducts are then transported to a biodiesel production facility where they undergo a series of processing steps. Once the grease and animal byproducts arrive at the facility, they are cleaned and processed to remove any impurities, such as water and solids. This step is crucial to ensure the quality of the final biodiesel product. The next step is the conversion of the grease and animal byproducts into fatty acids. This is done through a process called transest
