Techno-Economic Analysis of Sequential Extraction for Coffee Waste Valorization: Supercritical Ethanolic-CO2 Followed by Enzymatic Treatment
Short Introductive summary
This study investigates the valorization of defective green coffee beans (DCBs), a significant byproduct of coffee production in Thailand, through a sequential extraction process that combines supercritical CO2-based defatting and enzymatic treatment. By comparing three defatting methods—supercritical ethanolic-CO2, pure supercritical CO2, and ethanolic maceration—the research evaluates their technical and economic feasibility for producing bioactive peptides. Using techno-economic analysis (TEA), the study identifies the most cost-effective and sustainable approach, highlighting the potential of pure supercritical CO2 extraction for high-quality oil recovery and profitable peptide production. The findings support industrial-scale applications and contribute to sustainable waste-to-resource strategies in the coffee industry.
