Wet Extraction of By-Product Samples and Fractionation of Valuable Compounds using Supercritical CO2 Extraction: An Innovative Approach for Sustainable Resource Utilization

Ilze Luksta, Kriss Spalvins

Abstract


This research explores an innovative method for extracting and fractionating valuable compounds from by-product samples through the utilization of supercritical carbon dioxide (SC-CO2) extraction. By-products generated from various industrial processes often contain untapped reservoirs of valuable compounds, necessitating environmentally sustainable and economically viable extraction techniques. SC-CO2 extraction, known for its unique properties such as low toxicity, non-flammability, and tunable solubility, presents a promising avenue for efficient and selective extraction of target compounds.

The study focuses on wet extraction, emphasizing the extraction of valuable compounds from by-products in their natural, moisture-laden state. This approach not only enhances the sustainability of the extraction process by minimizing pre-treatment steps but also broadens the scope of potential target compounds. The study further explores the critical parameters of SC-CO2 extraction, including pressure, temperature, and flow rate, to optimize the extraction efficiency and selectivity for different classes of compounds.
