Many efforts are underway to try to reduce plastic pollution entering oceans, including beach clean-ups, bans on single-use plastics, and the continued development of reuse and recycling options. However, for countries to adequately meet these SDG targets, an important step is to understand the municipal solid waste management systems and practices, particularly those that may lead to plastic being released into the environment and identify the high priority areas to intervene. The aim of the WFD is to provide a rapid assessment methodology for mapping the flows of macro waste in a municipal solid waste management system at the city or municipality level, including quantifying the sources and fate of any plastic pollution.
WFD’s aim can be summarized into six objectives:
The Waste Flow Diagram maps macro plastic leakages hotspots and their flows from every stage of a Municipal solid waste management system to their fates. These fates could be plastic waste accumulation on land, leakage to water systems such as nearby pond, stream, rivers (which could bring the waste to the oceans), litter stuck in storm drains, and burning of plastic waste.
