The rapid expansion of biogas plants requires implementing effective measures to control air pollution, especially odors and greenhouse gas emissions.
Advanced technologies and pre-operational studies are essential to monitor, minimize, and prevent environmental impacts before the facilities become operational.

The new GRAL version 24.11 has been released, bringing important bug fixes, enhanced visualisations, and new features that improve the overall user experience. This update addresses issues in odour percentile calculations and source group management, introduces expanded export options, and changes the installation process to offer greater flexibility. The software remains open source, with its full code available on GitHub for those interested in exploring it further.
The release of GRAL 24.11 has sparked considerable interest among users of this atmospheric dispersion model. This version not only fixes bugs that previously affected the stability of certain functions but also adds visual and technical improvements that could transform how the tool is used in scientific and professional contexts. For those relying on GRAL, the update presents an opportunity to explore new capabilities and enhance their analyses.
This project demonstrates that multisensor systems with electrochemical sensors, enhanced by Data Learning models, can accurately and reliably monitor hydrogen sulfide (H2S) in wastewater treatment plants without costly or frequent manual calibration.
The pilot phase, conducted in early 2024, achieved excellent agreement with reference analyzers, offering a low-cost, low-maintenance, and innovative solution for continuous H2S measurement in WWTPs..
