Profile of highly infected wastes generated by hospitals: A case in Belo Horizonte, Brazil

Healthcare wastes are generated in facilities whose activities are related to human or animal healthcare. Wastes with high infectious potential risk to human health and the environment must be managed carefully, from generation to its final disposal. However, there is an absence of consolidated data addressing the healthcare waste qualitative classification generated by hospitals of a large city. Therefore, the present study aims to characterise qualitatively the high infectious waste generated by hospitals from Belo Horizonte city, Brazil, whose Health Services Waste Management Plan were approved and certificated by the municipal cleansing autarchy. Differences in the types of infectious wastes generated in maternity hospitals were identified (p 0.034), when compared with general (p 0.189), low (p 0.549) and high complexity (p 0.619), which can be explained owing to the extended hospital activities. This information suggests a similar profile of the qualitative generation of infectious wastes by hospital categories, as expected. The largest generation and diversity of high-infected wastes are associated with a greater variety of activities provided. The segregation can be considered as the main step in healthcare waste management, therefore, it is concluded that the correct classification leads to a better understanding of all those involved in the healthcare waste management
