ISWA “closing dumpsites” initiative: status of progress – article and editorial published

May 29, 2019

The International Solid Waste Association (ISWA) has determined that uncontrolled dumpsites hold 40% of the world’s waste and that the world’s 50 biggest dumpsites (identified through a voluntarily survey conducted by D-Waste in 2014) directly affect the daily lives of 64 million people, equivalent to the population of France.

The ISWA reports (2014, 2015a, 2015b, 2016) showcase how eliminating dumpsites is an urgent issue, affecting local, regional, and even global health and the environment. Important findings indicate that 38 out of the 50 biggest dumpsites directly impact marine and coastal areas and can become sources of disease outbreaks and the release of wastes (particularly durable plastics) to waterways and the oceans.

Studies suggest that non-engineered dumps and uncontrolled landfills are the third largest source of global anthropogenic methane, a greenhouse gas about 25 times more potent than carbon dioxide (CO2), accelerating climate change. It is estimated that open dumps emit the equivalent of more than 20 million metric tonnes [tons] of CO2 per year. Without any action, it is projected that existing open dumps will account for 10% of global greenhouse gas emissions by 2025.

If open dumps instead were replaced by engineered landfills with state-of-the-art landfill gas collection and destruction systems, it would be like removing five million cars from the planet.

In 2018, ISWA’s Working Group on Landfill (WGL) developed a Task Force on Closing Dumpsites (TFCD) and presented its dump closure initiative as one of its flagship projects for the future at the United Nations (UN) Conference on Housing and Sustainable Urban Development – Habitat III.
