Frequent Questions

What is the solid waste management hierarchy?

The four-tier solid waste management hierarchy ranks the most preferable ways to address solid waste. Source reduction or waste prevention, which includes reuse, is the best approach (tier one), followed by recycling (tier 2). Waste that cannot be prevented or recycled can be combusted with energy recovery (tier 3). Tier 4 is landfilling or incineration without energy recovery. Both of these disposal options take place according to proper regulations.
