Which disposal method is recommended for health care facilities without access to landfills, requiring treatment of waste first?

The recommended disposal method for health care facilities without access to landfills, which requires treatment of waste first, is safe burial. This method involves isolating the waste in a designated area that prevents any potential environmental contamination. It ensures that hazardous materials are buried in a manner that mitigates risks to public health and the environment.

Safe burial is particularly crucial for facilities that generate biomedical waste but do not have access to proper landfill sites. It helps avoid the leaching of harmful substances into the soil and groundwater, which could occur if the waste were disposed of improperly.

Other options, while they may have their respective applications, do not fully address the requirements of handling and treating health care waste, particularly in environments lacking landfill access. Inertization and composting typically involve processes that may not be suitable for certain types of medical waste, especially hazardous waste. Direct injection might refer to a process applied in specific waste scenarios but does not align with conventional practices for the comprehensive treatment of biomedical waste prior to disposal.
