Abstract
The accelerated generation of COVID-19 waste under the Delta-fuelled outbreak placed a sudden burden on waste disposal in Vietnam. To secure the treatment of COVID-19 waste amid the pandemic uncertainty, treatment capacity was assessed by determining treatment occupancy rate—the ratio of estimated demand to calculated capacity—both nationally and in Ho Chi Minh City. At the general occupancy rate for COVID-19 waste treatment of 7.4%, the country was capable of handling COVID-19 waste, with a capacity to treat 62 191 t month−1. However, Ho Chi Minh City became overwhelmed, indicated by a treatment occupancy rate of up to 780% during the Delta outbreak, as the unanticipated growth of demand for COVID-19 waste treatment caused waste to back up. The assessment results, in addition to current legislation, support collaboration in waste treatment as a solution to using existing resources to address the acute shortage of treatment capacity, so as to secure COVID-19 waste treatment. The findings could be used by other developing countries to tackle the waste problem in the pandemic era.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10163-022-01529-z.
