Waste Data Collection and Monitoring Tool for Informed Interventions
Waste Data Collection and Monitoring Tool for Informed Interventions


Many of worlds’ cities, especially in emerging countries, do not have waste data. Their data is not well-collected or monitored, sometimes not updated or have never been assessed. Lack of waste data and their monitoring, can lead municipalities to implement inappropriate waste management interventions that might worsen the waste status. In order to overcome this issue, waste data and waste flow in the cities should be collected and analysed. Therefore, UN-Habitat has developed a methodology to measure and monitor waste flows in cities.

Towards a Solution

To address this challenge, the United Nations Human Settlement Programme (UN-Habitat) developed the “Waste Wise Cities Tool” under the African Clean Cities Platform (ACCP) and the Waste Wise Cities campaign (WWCC). The Waste Wise Cities Tool is based on the monitoring methodology for waste SDG indicator 11.6.1, and provides an image of waste flows and amounts in the city. Key data includes the amount of waste generated, collected and managed in controlled facilities. Based on the data assessment and in close coordination with all relevant stakeholders, key interventions areas are identified and bankable projects are developed. This ensures long-term sustainability of the interventions.

The methodology enabled countries/ cities to obtain information of their existing waste management to establish strategy, reduce pollution to the urban environment, protect public health and tackle marine litter by knowing the leakages.

The tool was successfully piloted for collecting data in Nairobi and Mombasa, Kenya. The data collected in the year 2019 revealed that in Kenya, 74% Municipal Solid Waste (MSW) was collected out of which only 22% of MSW was managed in controlled facility. 800 tons/day remained uncollected. Similarly the statistics for Mombasa, 48% of MSW was collected of which only 2% is managed in controlled facilities and 450tons/day of waste remained uncollected.

These tangible datasets on waste SDGs helped inform the intervention to accelerate the actions on the ground, contributing towards the circular economy. As a result, waste management action plan for Nairobi was prepared and submitted to Executive Office of President. The National Waste Management Bill was also drafted and an Inter-agency task team to tackle municipal solid waste management formed. For Mombasa, a feasibility study for Refused Derived Fuel (RDF) facilities was identified as a key intervention to reduce marine litter. The tool assisted in supporting cities to determine the key areas of intervention, through a participatory approach involving stakeholders in the waste management chain, to identify and develop feasible/ bankable projects.

The methodology is being replicated/ implemented in 74 member cities (68 from Africa and 6 from Asia) of WWCC. To facilitate the systematic and cross-country transfer of the good practice and knowledge, UN-Habitat is developing an online course, step by step guide and video to train the members of ACCP and WWCC in the methodology. Member cities also receive the training and remote support to implement it, process and analyse the data. They will also be supported in the organization of a stakeholders workshop to present and discuss the results.
