Time to rethink medical disinfection from a planetary health perspective

Abstract

Disinfection products can have substantial environmental impacts which include associated manufacturing emissions, toxicity to marine life and potential adverse health outcomes. Despite this, disinfection is under-represented in sustainability approaches. Disinfection is a key part of healthcare provision and as such should be reflected in healthcare sustainability strategies. The adverse environmental effects of several common disinfectants are highlighted here. Sustainable alternatives should be considered. Hypochlorous acid (HOCl) is a potential alternative disinfectant that could be used in sustainability strategies, carrying a minimal toxicity profile compared to hypochlorite (bleach) and the unique ability to be made on site. Better clarity is needed regarding the environmental impact of disinfectants used in the healthcare setting and healthcare providers should move to seek sustainable alternatives such as hypochlorous acid.
