The rapid estimates provided by REVAMP are particularly intended to help city planners and policymakers at crucial decision points regarding waste management: for example, planning of new sanitation infrastructure, wastewater treatment plants or climate mitigation measures. It can also be useful for engineers, developers, researchers and anyone interested in the circular economy.
Based on data input about the volume of the different waste streams, REVAMP calculates the benefits from different reuse scenarios – for example composting of faecal sludge for agricultural fertilizer, production of biogas or solid waste briquettes – in terms of energy and nutrient content, how much of competing products they could substitute and what those products would cost. In this way, REVAMP can be useful for step for building a business case for different waste management/reuse options as well as informing scenario-based planning exercises.
REVAMP was initially developed under the SEI Initiative on Sustainable Sanitation. REVAMP has been piloted in Colombia and Kenya as part of the UrbanCircle project, which explores the governance dimensions that can facilitate transition to circular economy.
It has been developed into an open-access online platform with an improved user interface, reuse options and resources (including the water component of the waste streams) as well as costs and efficiencies of different technologies.
