Greenhouse gas emissions from wastewater treatment plants (WWTPs) may be more than twice as high as previously estimated, according to new research from Linköping University in Sweden. Using drones equipped with advanced sensors, scientists found that methane (CH₄) and nitrous oxide (N₂O) emissions from these facilities – particularly from sludge storage – are around 2.5 … Continue reading Drones reveal that wastewater plant emissions are greater than expected
