Sludge Treatment

Sludge treatment plays a critical role in environmental sustainability and the protection of water resources. It encompasses various techniques to manage and process sludge, a byproduct of wastewater treatment and industrial processes. This section will delve into two crucial aspects of sludge treatment: Biological Sludge Treatment and Dredging Sludge Management. Understanding these processes empowers industries and communities to effectively manage sludge, thereby safeguarding water resources and promoting ecological balance. By implementing these techniques, we can contribute to a cleaner, more sustainable future.



"Biosolids" is the generic name for several types of biological sludge. These are mainly sludges from municipalities, food processing and animal by-products. Although produced as waste, biosolids contain valuable organic matter. Therefore, large volumes of these materials are reused in agriculture, forestry, and landscaping in full alignment with the European Circular economy concept. Stabilization and hygienization are mandatory for biosolids before reuse. Carmeuse has developed the BioCalco® product range in order to fit the main processes of biosolids treatment and to maximize the multiple liming effect.

Dredging is essential for the navigability of ports and waterways for water and flood management. In line with the Circular Economy concept, dredged material can often be reused in several ways. Contaminated sediments, even if they occur in small volumes, can only be reused after special treatment. Contaminated sediments and their end use are subject to strict environmental limits. Carmeuse has developed the StabiCalco® product range to meet the requirements for the dredging sludge treatment.
