The rapid estimates provided by REVAMP are particularly intended to help city planners and policy-makers 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 is being developed under the SEI Initiative on Sustainable Sanitation. It is currently available in beta form. The current phase of development hopes to improve the user interface, as well as adding more reuse options and resources (including the water component of the waste streams), and taking into account the costs and efficiencies of different technologies.
