This study proposes integrating CO2 capture using deep eutectic solvents (DES) into a winery wastewater biorefinery. Aspen Plus simulation shows that the DES-based configuration reduces raw material costs by 48.86%, increases profit by 2.86%, and achieves an absolute annual CO2 reduction of 2,198 t, compared to a conventional CaO-based process. COD removal efficiency reaches 99.99%, enabling water reuse.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではCCUS技術としてアミン吸収法が主流だが、DESは低コスト・低環境負荷の代替案として注目される。本論文はワイン産業という特定産業における実証ではあるが、食品・飲料排水のバイオリファイナリーに拡張可能な知見を提供し、日本の産業廃棄物由来のCO2削減策として示唆に富む。
In the global GX context
While amine-based CO2 capture is dominant globally, deep eutectic solvents (DES) emerge as a promising alternative due to lower cost and environmental impact. This paper provides a techno-economic case for integrating DES-based capture into industrial biorefineries, supporting circular economy and decarbonization in the food and beverage sector—a sector often overlooked in CCUS discussions.

📄 Abstract（原文）
The wine industry generates large volumes of organic effluents, whose inadequate management poses significant environmental challenges but also offers opportunities for resource recovery. In this work, an integrated biorefinery scheme for the valorization of winery effluents is proposed and evaluated through steady-state simulation in Aspen Plus®. The biorefinery converts winery wastewater into a portfolio of value-added chemicals and biofuels, including levulinic acid, propylene glycol, formic acid, light gases, naphtha, sustainable aviation fuel, green diesel, and bioethanol, while enabling water recovery and carbon dioxide management. Two alternative CO2 capture routes are analyzed and compared: a conventional CaO-based carbonation–calcination process and an innovative absorption system using deep eutectic solvents (DES), specifically choline chloride–urea. Technical performance is assessed through chemical oxygen demand (COD) removal, recovery, conversion, yield, and product mass ratios. Economic feasibility is evaluated using profit-based indicators, while environmental performance is quantified through CO2-equivalent emissions associated with utility consumption. Results show that the proposed biorefinery achieves a COD removal efficiency of 99.99%, producing treated water compliant with Mexican regulations for internal reuse. The DES-based configuration reduces raw material costs by 48.86%, enables hydrogen recovery as an additional valuable product, and increases overall profit by 2.86% compared to the CaO-based scheme. Although the relative reduction in total CO2 emissions is modest (˜0.5%), the DES configuration achieves an absolute annual reduction of 2, 198 t CO2. Overall, the results demonstrate that integrating DES-based CO2 capture into winery effluent biorefineries enhances economic performance and supports circular economy principles through waste valorization, water reuse, and emissions mitigation.
