Define "waste disposal hierarchy."

The concept of "waste disposal hierarchy" refers to a structured approach to waste management that prioritizes actions based on their environmental impact. This hierarchy emphasizes minimizing waste generation and enhancing recycling and recovery practices before considering disposal as a last resort. The top levels of the hierarchy advocate for reducing waste production, reusing items, and recycling materials, each progressively less favorable than the previous option.

This prioritization reflects a commitment to eco-friendly practices, aiming to lower the negative effects of waste on the environment while promoting sustainable resource use. The recognition of the need for responsible waste management practices is central to effective hazardous materials response and environmental protection efforts.
