Medical wastes include all solid and liquid wastes that are produced during the treatment, diagnosis, and immunisation of animals and humans. A significant proportion of medical waste is infectious, hazardous, radioactive, and contains potentially toxic elements (PTEs) (i.e.

- The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has disrupted global health, economy, and the environment, revealing a complex relationship between the virus and environmental factors.
- Research shows SARS-CoV-2 can be found in soil and water, suggesting environmental transmission routes, but many studies haven't confirmed if detected viral genomes are capable of causing infection.
- Effective responses to COVID-related environmental challenges include eco-friendly disinfection methods and reducing plastic waste, indicating the need for sustainable practices to address both public health and environmental concerns concurrently.
A rotational sponge (RS) reactor was proposed as an alternative sewage treatment process. Prior to the application of an RS reactor for sewage treatment, this study evaluated reactor performance with regard to organic removal, nitrification, and nitrogen removal and sought to optimize the rotational speed and hydraulic retention time (HRT) of the system. RS reactor obtained highest COD removal, nitrification, and nitrogen removal efficiencies of 91%, 97%, and 65%, respectively.
