초록
The integration of waste-to-energy processes with CO₂ reduction and renewable energy storage was investigated. Here,we demonstrate a waste biorefinery that utilize biogas, which was previously used only for thermal energy. High valueaddedchemicals such as succinic acid, polyhydroxybutyrate (PHB) and synthetic natural gas can be produced by industrialmicroorganism from food waste and renewable energy. Water electrolysis facilities accounted for a significant portion of theinvestment cost. However, the rising demand for bioplastics helped shorten the payback period despite their relatively highprice. The quantity and economic feasibility of final products changed according to the order of the process, and the possibilityof circular waste biorefinery based on the use of biogas using renewable energy was suggested.
