A rapid assessment tool for mapping waste flows and quantifying plastic leakage potential in cities
The WFD directly integrates with SDG 11.6.1 to inform on municipal solid waste management indicators
Waste flows are mapped through all stages of a solid waste management system, including contributions from the informal sector and leakages to the environment
Emission pathways are determined using a unique and rapid, observational based assessment built on the concept of decision trees
As the world’s population nears 8 billion, so to our waste grows. Increase in consumption combined with rapid urbanisation, particularly in low- and middle-income countries, has put our cities at the forefront of dealing with the huge quantities of waste produced every day.
This global challenge, so frequently overlooked, has far reaching impacts tied to both human health and the environment, as recognised by its inclusion in many of the sustainable development goals (SDGs). Unfortunately, without improved knowledge on the waste flows within our cities, action cannot be taken to ensure sustainable solid waste management practices and avoid the damaging consequences of its mismanagement such as marine litter. The Waste Flow Diagram (WFD) toolkit enables cities and municipalities to quickly assess their municipal solid waste management system and map the flows of waste, thereby aiding in solving this critical issue.
The Waste Flow Diagram (WFD) toolkit enables cities and municipalities to quickly assess their municipal solid waste management system and map the flows of waste.
In short, the WFD aims to:
With a solid waste management focus, the WFD directly integrates with the SDG 11.6.1 methodology to inform on the performance of a cities SWM system. Using a rapid, observational based assessment, the WFD also estimates plastic leakages to the environment to provide comparative indicators of plastic pollution. All waste flows are summarised in easy to visualise Sankey diagrams.
