Anaerobic digestion (AD) is an important technology for renewable energy production and waste management, but it also generates large volumes of digestate that must be effectively managed to realize its full sustainability potential. This review examines the key characteristics of digestate and how they influence opportunities for its valorisation into useful products. It assesses current technologies, including separation methods and advanced processing pathways, and discusses their technical and economic implications. Policy and regulatory considerations are also highlighted. Overall, the review provides guidance for researchers, industry stakeholders, and policymakers working to advance circular economy strategies.
