Regarding municipal solid waste management, what is the purpose of a waste hierarchy?

The purpose of a waste hierarchy is to establish a framework that prioritizes waste management practices based on their environmental impact, promoting more sustainable options. At the top of the hierarchy is waste prevention, which is the most favorable approach, followed by reuse, recycling, recovery, and finally disposal, which is the least desirable option. This approach encourages the reduction of waste generation and maximizes resource recovery, leading to reduced environmental burdens and more efficient use of materials.

Prioritizing management options helps municipalities and organizations make informed decisions about how to handle waste effectively, aiming to minimize landfill use and promote more responsible consumption and disposal practices. By focusing on practices that have the least negative impact on the environment, the waste hierarchy serves as a guiding principle in waste management strategies and policies.
