Constructed floating wetlands cut greenhouse gas emissions from wastewater lagoons
Abstract
O emissions (18%). Total Kjeldahl nitrogen levels (primarily organic nitrogen) declined by 12%, whereas nitrate and phosphorus remained unaffected. Notably, emission reductions emerged within four to seven months of CFW installation, preceding detectable nutrient reductions, which only became evident after 12 months. Altogether, our findings provide one of the first full-scale demonstrations that CFWs can substantially reduce greenhouse gas emissions from wastewater lagoons and support their potential as a nature-based pathway for decarbonising the water sector.
