The main byproduct is glycerol, which can be purified and used in pharmaceuticals, cosmetics, or as a carbon source in anaerobic digestion. Residual materials from oil extraction (like liver tissue) can be processed into fishmeal or fertilizer, enhancing sustainability. The GlobeCore USB plant includes glycerin separation and methanol recovery systems, reducing waste and operational costs. Effective byproduct use supports circular bioeconomy models, especially in coastal or fishing communities where waste valorization is essential.
