Open burning of municipal solid waste (MSW) is a common practice, especially in developing countries with inadequate solid waste management systems. Currently, two billion people globally have no waste collection, and the waste generated by over three billion people is either dumped or subject to uncontrolled burning (Circular, 2019). Moreover, open burning of MSW typically occurs under relatively low temperatures, and this emits a significant amount of pollutants, such as particulate matter (PM10, PM2.5), particulate black carbon (BC) and organic carbon (OC), and gaseous pollutants like nitrogen oxides (NOx), carbon monoxide (CO), methane (CH4) and non-methane volatile organic compounds (NMVOC) (UNEP, 2013). In addition, open burning of waste results in emissions of a wide array of potentially hazardous substances i.e polyromantic hydrocarbons, mercury, arsenic, fine dust, sulfur oxides, and hydrochloric acid, most of which are toxic and harmful to the environment and human health (UNITAR and UNIDO, 2019). Any actions to mitigate open waste burning could improve the environment and human health. and could also contribute to global initiatives such as Global Methane Pledge, Net-Zero Initiative, Paris Agreement, etc. Hence, considering the urgency to address this issue in Asia, IGES-CCET conducted a study on open waste burning in selected Asian cities and drafted a report based on the study which currently under review and is due to be finalised soon. In addition, IGES-CCETalso organised a webinar on open waste burning in April 2022, inviting national and international partners to discuss the finding of the study. This session will be a follow-up event to the webinar with featuring discussions on “Global initiatives and good practices for mitigating open waste burning”.

Open waste burning is a widespread practice that is provoked by a lack of systematic waste collection, the unavailability of other disposal options, and inadequate land for the final disposal of the collected waste, especially in low- and middle-income countries. From a global perspective, two billion people have no waste collection at all, and the...
