Importance of Water and Energy Integration in Circular Economy Approach

摘要: FOR CIRCULAR ECONOMY: BOOK OF ABSTRACTS should not be considered as waste because it is a valuable resource for freshwater, energy, and materials. Reusing, regenerating, and recycling wastewater can provide economic and environmental benefits such as reducing freshwater and energy consumption and greenhouse gas emissions and recovering valuable materials from wastewater. To achieve these goals, systematic approaches for water and energy integration should be applied to design optimal water and energy network solutions. In the last several decades, pinch analysis, mathematical programming and hybrid approaches have been successfully applied to design combined water and energy networks with optimal water and energy consumption (Ahmetović et al., 2015, Budak Duhbacı et al., 2021). The main focus of this work is to show the importance of water and energy integration and applications of systematic methods in a circular economy approach for optimising water and energy reuse in manufacturing processes and highlight possible future directions in this research field.
