Valorization of sugarcane stillage by extraction of aconitic acid
Last Updated: junio 19, 2025Cane stillage or vinasse, a co-product of ethanol distilleries, contains 5-7 g/L of aconitic acid, a valuable trivalent carboxylic acid that is an important building block in organic synthesis. Vinasse also contains a variety of other organic compounds (e.g., organic acids, amino acids, colorants) and minerals (e.g., chlorides, sulphates), which make purification difficult.
Value-added products from vinasse
Last Updated: junio 19, 2025Environmental projects can now generate value-added products using different technologies, utilizing existing vinasse volumes and approaching zero-effluent models. These new technologies can use all the available vinasse or create mixed models that share vinasse with existing use options such as fertigation and composting.
