With the new Sustainable Development Goals (SDGs), particularly with goal 6.3, the focus is shifted towards the improvement of water quality "by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater, and increasing recycling and safe reuse globally". In general, the SDGs are more focused on the path from the user's interface to the treatment and even resource recovery and reuse.

 

 

Cities are facing different challenges regarding sanitation and resources. There are still 700mio people lacking improved sanitation access globally (of which 80mio still practice open defecation). Furthermore, cities are major resource consumers and the pressure on our resources is growing further (urban population growth, water demand growth, climate change impacts).

Inspired by the Shit Flow Diagrams (SFD) the Resource Value Mapping (REVAMP) Tool was developped. It is a tool for evaluating the resource revocery potential of urban waste streams.

 

Objectives of the REVAMP Tool

Support integrated waste resource management and recovery, advancing in sustainable water and sanitation service, and addressing multiple urban development challenges through incresed cross-sectoral stakeholder engagement.

 

Target users

Policy-makers and planners, water, sanitation and waste managers, entrepreneurs and inverstors; development practitioners, students and researchers

 

Key initial features
  • Estimate the resources that could be recovered in various forms (such as water, plant nutrients, biogas)
  • Estimate quantities of reuse products that could be produced
  • Estimate potential revenues from different reuse products
  • Comparison of reuse options, based on energy and nutrient content, and potential revenues, - to support decision making on city sanitation and waste management plans.
