Can wastewater treatment solve food shortages? This paper explores using biosolids from wastewater treatment plants in agriculture to address the global population explosion and water scarcity. It posits that turning sludge into biosolids provides an ideal soil conditioner and fertilizer. The main content focuses on wastewater treatment practices in Germany, including directives and guidelines. It emphasizes that if operationally efficient logistics, administration, and cost management systems are in place, what is deemed a threat can be transformed into a bonanza.
Within the scope of Environmental Management and Health, this paper addresses a crucial intersection: leveraging wastewater treatment to improve agricultural sustainability. It explores how biosolids can be managed to mitigate environmental concerns while addressing food scarcity, aligning with the journal's focus on integrated approaches to environmental and health challenges.
