Criteria for classification and destination of healthcare wastes with potential biological risk: comparison between Brazil and Portugal

Abstract

Healthcare wastes (HCW) have potential sources of disease spread, however, only a small fraction presents a high potential risk. It is important for the scientific community to discuss topics about these risks. This study aims to evaluate the classification and destination of HCW in Brazil and in Portugal, with a particular focus on infectious wastes. A bibliographical research was carried out based on scientific papers and legal instruments about HCW management. Wastes with lower infectious hazard, A4 subgroup in Brazil, do not require previous treatment before final disposal. In Portugal, differences in classification system suggested that the Brazilian A4 subgroup is comparable with some wastes from patient's rooms and health assistance areas, considered as high risk. These differences influence the management system, particularly in relation to infectious waste. Both Brazilian and Portuguese standards recommend safety during the management process, aiming at the protection involved workers.
