Utilization of Waste Sludge in Environment-friendly in Construction Materials

The aim of this project is to investigate the feasibility of using sewage sludge and by-products from incineration and power plants for construction materials production. In this study, different sludge samples collected from various wastewater treatment plants in Hong Kong will be analyzed and characterized; the feasibility of making construction materials from the wastewater sludge and improving the brick quality by the incorporation of waste resides collected from local power plants will be examined. The environmental impacts and toxicity of the final products will be also evaluated.
