In the context of healthcare waste, what does energy recovery involve?

Energy recovery refers to the process of converting waste materials into usable forms of energy, primarily through the generation of electricity or fuel. This process typically involves techniques such as incineration or anaerobic digestion, where waste is subjected to high temperatures or specific biological environments. The outcome is the capture of energy that can be utilized for power generation or industrial processes, thus providing a sustainable way to manage waste while simultaneously addressing energy needs.

While other options like converting waste into reusable products or processing it for composting may be part of waste management strategies, they do not directly relate to energy recovery. The focus of energy recovery is specifically on transforming waste into fuel or electricity, making choice C the most appropriate in this context.
