Converting wastewater sludge into slow-release fertilizers improves nutrient recovery and supports sustainable agriculture.
The review identifies that wastewater sludge contains rich nutrients like nitrogen, phosphorus, and potassium, essential for soil health.
Techniques such as biochar production and encapsulation enhance nutrient efficiency, yet technical and regulatory hurdles limit widespread application.
Innovative solutions and supportive policies are crucial for transforming sludge-based fertilizers into mainstream agricultural practices.
