Where must incubator rejects be sent for proper disposal?

The correct answer is that incubator rejects must be sent for crushing and denaturing. This process is essential for the safe disposal of materials that are not suitable for further use or consumption. Crushing and denaturing involves treating the rejected materials in such a way that they are rendered unrecognizable and non-reusable, ensuring that any potential hazards associated with these materials are neutralized. This method is particularly important in preventing contamination and maintaining safety standards in waste management, especially for materials that could pose risks to human health or the environment.

Other disposal options like sending materials to a landfill, a compost facility, or for further inspection do not adequately address the need for safe processing of rejects. Landfilling may lead to potential environmental harm, composting is inappropriate for materials that are non-biodegradable or hazardous, and further inspection delays the necessary action of disposing of items that cannot be salvaged. Hence, the recommended practice of crushing and denaturing leads to proper and responsible waste management.
