The World Health Organisation (WHO) has warned this morning the world is facing a medical waste emergency in the wake of the efforts to fight the COVID pandemic.
It said a new study has revealed tens of thousands of tonnes of extra medical waste from the response to the COVID-19 pandemic has put tremendous strain on health care waste management systems around the world, threatening human and environmental health and exposing a dire need to improve waste management practices. according to a new WHO report.
As the UN and countries grappled with the immediate task of securing and quality-assuring supplies of PPE, less attention and resources were devoted to the safe and sustainable management of COVID-19 related health care waste.
“A systemic change in how health care manages its waste would include greater and systematic scrutiny and better procurement practices,” said Dr Anne Woolridge, chair of the Health Care Waste Working Group, International Solid Waste Association (ISWA). “There is growing appreciation that health investments must consider environmental and climate implications, as well as a greater awareness of co-benefits of action. For example, safe and rational use of PPE will not only reduce environmental harm from waste, it will also save money, reduce potential supply shortages and further support infection prevention by changing behaviours.”
The WHO Global analysis of health care waste in the context of COVID-19: status, impacts and recommendations bases its estimates on the approximately 87,000 tonnes of personal protective equipment (PPE) that was procured between March 2020- November 2021 and shipped to support countries’ urgent COVID-19 response needs through a joint UN emergency initiative. Most of this equipment is expected to have ended up as waste.
The authors cautioned the figure provided an initial indication of the scale of the COVID-19 waste problem. It does not take into account any of the COVID-19 commodities procured outside of the initiative, nor waste generated by the public like disposable medical masks.
They pointed out that over 140 million test kits, with a potential to generate 2,600 tonnes of non-infectious waste (mainly plastic) and 731,000 litres of chemical waste (equivalent to one-third of an Olympic-size swimming pool) have been shipped, while over 8 billion doses of vaccine have been administered globally producing 144,000 tonnes of additional waste in the form of syringes, needles, and safety boxes.
The report added 30% of healthcare facilities (60% in the least developed countries) are not equipped to handle existing waste loads, let alone the additional COVID-19 load. This potentially exposes health workers to needle stick injuries, burns and pathogenic microorganisms, while also impacting communities living near poorly managed landfills and waste disposal sites through contaminated air from burning waste, poor water quality or disease carrying pests.
“COVID-19 has forced the world to reckon with the gaps and neglected aspects of the waste stream and how we produce, use and discard of our health care resources, from cradle to grave,” said Dr Maria Neira, director, Environment, Climate Change and Health at WHO. “Significant change at all levels, from the global to the hospital floor, in how we manage the health care waste stream is a basic requirement of climate-smart health care systems, which many countries committed to at the recent UN Climate Change Conference, and, of course, a healthy recovery from COVID-19 and preparedness for other health emergencies in the future.”
