The primary byproduct is glycerin, which can be refined and used in pharmaceuticals, cosmetics, and industrial applications. Other byproducts include soap stock, seed meal (if whole soybeans are processed), and methanol-water mixtures. With the GlobeCore USB system, glycerin is cleanly separated, and methanol can be recovered for reuse, improving the sustainability and profitability of production. The integration of these byproducts into other industries enhances the circular economy of biodiesel manufacturing.
