Greenhouse Gases diagnosis
Atmospheric emissions are an increasing concern, posing challenges for air quality and global warming. For that reason, we public authorities and industries have supported addressing these challenges by developing solutions diagnostic of these emissions.
ClimateAdvanced® Study
An essential study to understand and control greenhouse gas emissions from industrial facilities.
ClimateAdvanced® Study is used to detect sources and leaks of greenhouse gas emissions in order to implement actions to reduce your environmental footprint.
Thanks to the data measured at your facility, you will be able to accurately identify and understand your GHG emissions and take action to reduce them.

Supply and commissioning of a biogas upgrading system (Barcelona)
In June 2021, the energy company NATURGY became a pioneer in injecting renewable gas, or biomethane, into Spain's gas distribution network from landfill gas. This facility, located in Parc de l’Alba in Cerdanyola del Vallès (Barcelona), next to the controlled Elena landfill, was made possible through the use of the VALOPUR® membrane biogas upgrading system. The plant will produce 12 GWh of biomethane annually.
