Degradation of municipal waste within the landfill body under anaerobic conditions produces leachate enriched in ammonia.

leachate is treated in wastewater treatment plant transported by truck of by sewage system to the nearest plant.
regional authorities push waste sector operators to face the PFAS (perfluoroalkyl compounds) emergency. In this context the exigence to monitor and remove these compounds from the leachate has an increasing preponderance.
