Sanitation Policies and Regulatory Frameworks for Reuse of Nutrients in Wastewater, Human Excreta and Greywater

The proceedings detail a two-day workshop in Sweden where experts from various global 'knowledge nodes' discussed the barriers and drivers for implementing nutrient reuse in sanitation. Key findings highlight a persistent gap between national legislation and local enforcement, the necessity of 'champions' to drive policy change, and the importance of technology-neutral policies that prioritize actual reuse over the mere possibility of recycling. Case studies from Sweden, the Philippines, Uganda, Colombia, South Africa, and China illustrate diverse regional challenges, including urban transport costs for nutrients and the social stigma associated with excreta reuse.

• There is a significant disconnect between national-level legislation and local enforcement, meaning that revising laws does not automatically result in functioning reuse systems.
• In Sweden, the Environmental Code (1999) legally mandates that reuse and recycling be encouraged to maintain natural cycles, yet these provisions are rarely enforced by authorities.
• The Philippines Clean Water Act of 2004 primarily focuses on pollution control, but its implementing rules and regulations were influenced to include exemptions from wastewater charges for those using ecological sanitation (Ecosan).
• Uganda faces challenges where national policies on ecological sanitation are not implemented at the municipal level because politicians avoid enforcing laws that might be unpopular with voters.
• In Colombia, the legal framework for reuse is limited because 'excreta' is not mentioned in policy documents and there are no established norms for contamination levels.
• South Africa's 'Free Basic Sanitation Policy' has led to a lack of community ownership, which subsequently results in poor operation and maintenance of sanitation systems.
• China has a long history of excreta reuse in rural areas, but urbanisation has complicated the process due to increased costs associated with the collection, treatment, storage, and transport of nutrients.
• Effective policy change requires 'champions'—influential individuals or institutions—and a clear vision that is communicated across different sectors, including agriculture and finance.
• The WHO Guidelines for the Safe Use of Wastewater, Excreta and Greywater provide a risk-management framework to protect health by recommending minimum safe practice requirements and identifying exposure points.
• Policies should be technology-neutral to allow for innovation, focusing on the target outcome (nutrient reuse) rather than specifying a particular type of toilet.
