Clean and Green

The Stockholm Environment Institute (SEI) is developing the 'Clean and Green' framework to address gaps in rural sanitation, specifically for smallholder communities. The framework combines a 'Clean' track for risk management (eliminating open defecation and managing waste) and a 'Green' track for resource recovery (recycling nutrients and water for agriculture). It utilizes a stepwise certification system to motivate households and villages, aiming to synergistically meet multiple Sustainable Development Goals (SDGs) by linking sanitation to agricultural productivity and ecosystem health.

• Existing rural sanitation approaches often fail to scale or sustain long-term use because they focus exclusively on health outcomes without resource recovery, or focus on ecological sanitation without addressing social and institutional barriers.
• The 'Clean and Green' framework operates through two integrated tracks: the 'Clean' track focuses on sanitation and hygiene risk management, while the 'Green' track encourages the safe and productive reuse of local waste streams.
• The 'Clean' track utilizes a three-step certification process for villages: 'Basic Sanitation Village' (open defecation eliminated), 'Sustained Sanitation Village' (universal use of toilets and handwashing), and 'Total Sanitation Village' (safe management of solid waste, animal excreta, and wastewater).
• The 'Green' track focuses on the household level, certifying 'Productive Households' that safely reuse waste flows such as greywater, human urine and faeces, animal manure, food waste, ash, and crop residues.
• Productive sanitation offers significant economic potential for smallholder farmers; for example, in Burkina Faso, the nutrients in one year of excreta from a family of 10 are roughly equivalent to 50kg of commercial urea and 50kg of commercial NPK fertilizer, valued at approximately 80 USD.
• To ensure health is not compromised during resource recovery, the framework requires the establishment of safety criteria, including the use of exposure barriers, specific crop choices, and regulated timing, dose, and location for waste application.
