Abstract:
The chemical industry is a significant contributor to greenhouse gas emissions due to its high reliance on fossil fuels and inadequate waste management techniques. To address climate change and promote long-term sustainability in chemical industrial processes, deploying circular zero-waste approaches that capture and utilize biogenic CO2 to produce renewable biochemicals is essential. This study aims to develop a consistent methodology combining life cycle thinking and multi-criteria decision analysis to evaluate and prioritize hybrid solutions that integrate innovative biotechnological and intensified chemical conversion processes. These solutions are used to formulate seven high-value chemicals and polymers from industrial biogenic CO2 emissions and renewable resources. Utilizing a hybrid AHP-TOPSIS approach, the methodology considers economic, environmental, and technological factors to select the optimal biochemical production pathway according to industrial stakeholders’ preferences. Results indicate that producing long-chain dicarboxylic acids maximizes the environmental benefits, while hydroxycarboxylic acids are optimal from economic and technological perspectives.
