The main byproduct is glycerin, which can be refined for use in soaps, cosmetics, or industrial lubricants. Protein residues and bone meal can be processed into animal feed supplements, fertilizer, or biogas substrates. Integrated systems like the GlobeCore USB plant allow easy glycerin separation and methanol recovery, enhancing byproduct management and profitability. Utilizing waste streams also strengthens the environmental profile of pork fat–based biodiesel operations.
