The 19th IWA World Conference on Anaerobic Digestion (AD19) covers a wide range of topics related to the evolution of anaerobic digestion from a waste-treatment process to a key pathway for circular resource recovery. The main themes include industrial wastewater valorisation, decentralised AD systems, biogas upgrading, biorefinery concepts, novel and integrated technologies, modelling and digital tools, sustainability assessment, microbial ecology, and contaminant monitoring.
Importantly, the conference also features a specific topic dedicated to adding value to liquid streams and digestate, which explicitly includes the treatment and upgrading of liquid digestate, nutrient recovery, water reuse, carbon valorisation and management of contaminants. This makes AD19 particularly relevant for anyone working on digestate processing and the development of nutrient-rich bio-based fertilisers.
