Background 2 Request for Proposals: Integrated management of a composting unit in Dakar: from collection and segregation to transport and compost production. In recent years, Dakar has experienced rapid population growth, which is an important factor for authorities to consider in delivering quality public services in various sectors. This includes solid waste management, where the generated quantities have significantly increased - with the Dakar region, increasing from 475,000 tons in 2008 to 893,000 tons in 2018. The rapid demographic growth, combined with the small area of the city of Dakar (79 km2), contributes to land pressure. Dakar has one of the highest population densities in the country, with 18,212 inhabitants per square kilometre. This limited land availability is one of the many challenges to expanding waste treatment and disposal facilities. All waste produced by the city is disposed of outside the city limits at the Mbeubeuss dumpsite. 2.2 Transforming Cities Waste Management Programme Organic waste (food waste and other biodegradable waste) comprises between 30% and 60% of the total municipal solid waste generated in African cities, and this organic waste is responsible for up to 20% of city greenhouse gas emissions, primarily as methane from landfills and dumpsites. In terms of city powers and transformational potential, action to reduce organic waste disposal represents an immense opportunity to reduce methane emissions and deliver significant local benefits on public health, sanitation, and job creation. According to the latest International Panel for Climate Change (IPCC) Report, addressing methane emissions is the single fastest and most effective way to address current global warming. African cities have a unique opportunity to contribute to this global mission by implementing sustainable waste management systems. C40 is working with cities to dramatically reduce current and future emissions by strategically engaging political leadership to deliver the most impactful waste management priorities captured in their respective Climate Action Plans, while also building technical, institutional, and operational capacity in the supported cities. The Transforming Cities Waste Management Programme looks into supporting cities to transform city waste management whilst reducing methane emissions. The Programme provides the City of Dakar with the preliminary tools needed to establish sustainable waste management systems and the foundational requirements to accelerate the delivery of the Pathway Towards Zero Waste. Cities are high-impact change agents and improving waste management is a key opportunity for cities to reduce methane emissions, and a key priority for mayors. 3 Request for Proposals: Integrated management of a composting unit in Dakar: from collection and segregation to transport and compost production. C40 Cities is supporting the City of Dakar in closing collection gaps, improving residual waste disposal solutions, increasing organics diversion alternatives, and creating and upskilling jobs. The programme has supported the City in executing a Waste Composition Study, Mass Flow Analysis, a Project Preparation Assessment for the Establishment of Organic Waste Processing Facilities, trained city officials on sustainable waste management, developed an implementation plan for organic waste diversion from final disposal with a preliminary design for an organic waste compost facility and a pilot project to initiate segregation of waste at source in the public markets. This pilot project is currently being implemented in the Castor and Tilène markets. Subsequently, C40 in collaboration with the city will be working on commissioning an organic waste composting facility. This will go a long way in provid
