Resource Value Mapping (REVAMP): A tool for evaluating the resource recovery potential of urban waste streams

The Stockholm Environment Institute has developed Resource Value Mapping (REVAMP), a tool designed to help urban planners and investors identify the economic and material value of resources recoverable from sewage sludge, faecal sludge, and organic solid waste. Unlike previous tools, REVAMP operates at a city-wide scale and is specifically tailored for the Global South by incorporating on-site sanitation data. A 2016 trial in Kampala, Uganda, demonstrated that 100% collection of the city's organic waste could generate significant daily revenues and substitutes for firewood and chemical fertilizers, with solid combustion fuel offering the highest potential daily revenue of US$225,500.

• REVAMP is designed to estimate the quantities and potential revenues of various reuse products from city-scale organic waste streams, including sewage sludge, faecal sludge, and food/organic solid waste. It currently evaluates products such as biogas, solid combustion fuel, insect larvae for livestock feed, and compost fertilizer/soil conditioner.
• The tool is specifically adapted for the Global South because it accounts for faecal sludge from on-site sanitation systems, which are common in many cities, whereas earlier tools typically focused only on large-scale sewage collection.
• A 2016 trial in Kampala, Uganda, using a scenario of 100% waste collection, identified four primary resource recovery options with varying daily revenues and impacts: solid combustion fuel (US$225,500 daily revenue, substituting firewood for 1,108,700 people), biogas (US$121,000 daily revenue, substituting firewood for 824,000 people), black soldier fly larvae (US$42,200 daily revenue, substituting 134 tonnes of dried fish meal), and composted fertilizer (US$4,500 daily revenue, substituting 5 tonnes of urea fertilizer).
