On behalf of the Organizing Committee and the Scientific Committee, we warmly welcome you to the XIV Latin American Workshop and Symposium on Anaerobic Digestion (DAAL XIV), which will take place in the city of Querétaro, Mexico, from October 23 to 27, 2023. After the pandemic period caused by SARS-CoV-2, we will celebrate this great event that has historically been the main platform to present scientific and technological advances related to anaerobic digestion, and that has the support of the International Water Association (IWA) and its group of specialists in anaerobic digestion. This event is organized by the Engineering Institute of the National Autonomous University of Mexico (UNAM).

DAAL XIV will be a space to discuss the new scientific and technological advances and challenges of processes related to the anaerobic treatment of wastewater, revalue of solid waste, recovery of nutrients and other precious products, emphasizing their contribution to the circular economy.
