NEW PUBLICATION - Characterization of the gaseous and odour emissions from the composting of conventional sewage sludge

A new paper titled " Characterization of the gaseous and odour emissions from the composting of conventional sewage sludge" by Daniel González Alé, Nagore Guerra, Joan Colón, David Gabriel, Sergio Ponsá and Antoni Sánchez has been published in Atmosphere (11), 211 doi:10.3390/atmos11020211

In this work, full inventory of the gaseous and odorous emissions generated during the bench-scale composting of conventional sewage sludge, aiming at assessing the process performance and providing global valuable information of the different gaseous emission patterns and emission factors found for greenhouse gases (GHG) and odorant pollutants during the conventional sewage sludge composting process. The main process parameters evaluated were the temperature of the material, specific airflow, average oxygen uptake rate (OUR), and final dynamic respiration index (DRI), resulting in a proper performance of the sewage sludge composting process and obtaining the expected final product.

This work is the result of the collaboration of three research groups: the GICOM and GENOCOV groups from the Department of Chemical, Biological and Environmental Engineering at Universitat Autònoma de Barcelona and the BETA-TECH Center from the Universitat de Vic.
