Environmental Health Report: From health sector waste minimisation towards a circular economy
Of the 1.47 billion tonnes of solid waste that is produced each year globally, 5.9 million tonnes (approx. 16,164 tonnes per day) are estimated to be a result of health care waste. This figure has increased year on year, and the COVID-19 pandemic has served as an extreme example of the challenges for sustainable health care waste. Aotearoa New Zealand's health care sector is estimated to contribute between 3% and 8% of national carbon dioxide equivalent (CO2e) emissions. For comparison, the UK and the USA emit 4% and 10%, respectively, of their national CO2e from health care. Efforts are required to reduce waste production, landfill use and unnecessary procurement costs that arise from district health board activities, thus realising financial, environmental, cultural, health, wellbeing and social benefits.
