Abstract
Due to rapid urbanization, increasing population, and developing living conditions, the amount of solid waste is increasing every year all over the world. Waste-to-energy technology, especially anaerobic digestion, is recognized as a potential and promising technology for sustainable and environmentally friendly energy production. This study aims to propose the management of the digester liquids produced in biogas/biomethane plants and classified as waste and to ensure that they are taken into consideration within the scope of the circular economy. With the help of existing literature, this research developed a systematic procedure that can be used to properly manage waste. This study proposed that a significant amount of energy recovery will be achieved with the establishment of facilities that produce biogas from domestic organic solid waste and other organic wastes.
