Luxembourg's sewage sludge production reached 10,826 tons of dry matter in 2024, up from approximately 8,500 tons in the late 2010s. The Ministry of the Environment projects that annual output may reach 15,000 tons by 2040 due to demographic growth and increased wastewater processing.
Currently, over 8,200 tons are exported for disposal, highlighting reliance on foreign incineration and logistical risks. The government is investigating domestic processing solutions, including biogas production and thermal recovery methods. A specialized study has been commissioned to identify sustainable management practices to transition towards a resource-recovery model.
