Conclusion
Final disposal of sewage sludge

Sewage sludge management lies at the intersection of environmental, economic, and social considerations.

Given the wide variety of sources and characteristics of sludge, there is no one-size-fits-all solution: each disposal or recovery method has its own advantages, constraints, and limitations, which require an approach tailored to each region and regulatory context.

The development of innovative solutions — —such as energy recovery, reuse in agriculture under strict conditions, and advanced processing methods — —opens up promising avenues for reducing the environmental impact of sludge and promoting its integration into material and energy cycles.
