Main byproducts include glycerin, which can be refined for cosmetic, soap, or industrial use, and methanol-water mixtures, which can be recovered and reused. Solid residues from rendering (bones, proteins) can be processed into animal feed, fertilizer, or biochar. The GlobeCore USB system includes features for glycerin separation and methanol recovery, improving profitability and environmental sustainability. Maximizing byproduct utilization contributes to a circular and economically efficient operation.
