We warmly welcome all participants of the 19th IWA World Conference on Anaerobic Digestion (IWA AD19), taking place in Valencia, Spain, from June 9 to 13, 2026. As one of the premier international gatherings dedicated to anaerobic technologies, IWA AD19 will serve as a platform to explore the latest advancements and innovations in this dynamic field.
Anaerobic technology has evolved from a cost-effective solution for waste treatment into a comprehensive approach for transforming waste into valuable resources. We firmly believe that advancing this technology is essential for building a more sustainable future. The conference theme, “Fueling Sustainability,” underscores the pivotal role anaerobic digestion plays in achieving environmental resilience.
IWA AD19 aspires to bring together a diverse community of academics, scientists, engineers, researchers, practitioners, policymakers, and representatives from both the public and private sectors. This event offers a unique opportunity to exchange insights, share research, foster collaboration, and inspire new ideas. We hope that the conference will contribute meaningfully to shaping the future roadmap of anaerobic digestion.
We sincerely hope you find the conference both enriching and enjoyable, and that your time in Valencia is memorable and rewarding.
