What does the term "waste-to-energy" refer to?

The term "waste-to-energy" specifically refers to the process of converting non-recyclable waste materials into usable forms of energy. This method typically involves the combustion of waste materials to produce heat, which can generate electricity or provide heating. The concept is rooted in the idea of utilizing waste that would otherwise end up in landfills and thus reduces the volume of waste while also creating energy as a byproduct.

This definition is aligned with current waste management practices aimed at both reducing landfill use and providing renewable energy sources. Options related to recycling, minimizing waste output, or landfilling do not capture the essence of waste-to-energy, as they focus on different aspects of waste management. Recycling of plastics is about reusing materials, minimizing waste output emphasizes reduction, and landfilling involves disposal rather than energy recovery. Each of these has distinct objectives and methods that do not align with the energy production aspect of waste-to-energy systems.
