What is REVAMP?

Resource Value Mapping (REVAMP) is a decision support tool for rapidly estimating the resource recovery potential from organic waste streams: sewage sludge, faecal sludge and other organic solid waste. REVAMP calculates the potential amount of recovered product, its energy and nutrients contents and the potential revenue that could be obtained when sold for different scenarios.

What does REVAMP do?

REVAMP helps city planners estimate the total resources and reuse potential available in a city’s wastewater and other organic waste streams, as well as their financial values.

Who is REVAMP for?

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.
