Application of municipal sewage sludge ash in production of eco-efficient construction materials
Description
Application of municipal sewage sludge ash in the production of eco‑efficient construction materials, reducing landfill use and environmental impact.
Sector
A1.6Support activities to agriculture and post-harvest crop activities
Needs/ Problem statement
Ash from sewage sludge is potentially hazardous and underutilized. Current disposal via landfilling poses environmental risks. There is a need for sustainable solutions to recycle this waste into construction materials.
Objective
Develop and validate technologies for incorporating municipal sewage sludge ash into eco-efficient construction materials, reducing environmental risk and supporting circular economy principles.
