Our group members attended the 19th IWA World Conference on Anaerobic Digestion (IWA AD19), held in Valencia, Spain, from June 9-13, 2026. The group's participation included workshop sessions, oral presentations, and poster contributions, showcasing recent advances across several areas of anaerobic biotechnology. Take a look the research highlights and key findings that our team brought to AD19:

Raúl Muñoz and Raquel Lebrero contributed to the Workshop Tracks with the following presentations: “Biogas upcycling to added value bioproducts”, “Upgrading biogas or burning it? Pathways to energy self-sufficiency in 2045”, and “Biogas Upgarding”.

We were pleased to share our group's latest research through the following oral presentations:
