Operation and Monitoring:

1. Waste Acceptance: C&D waste landfills typically accept a specific type of waste, and any waste brought to the site must meet the acceptance criteria. The waste is weighed upon arrival, and any non-acceptable waste is rejected.

2. Placement and Compaction: The acceptable waste is then placed in the landfill and compacted to reduce its volume and ensure stability.

3. Covering: At the end of each day, the waste is covered with a layer of soil or other cover material to control odor, pests, and dust.

4. Monitoring: Throughout the landfill’s operation, continuous monitoring is conducted to ensure that it is operating safely and in compliance with all regulatory requirements. This includes monitoring the leachate collection system, the gas management system, and the groundwater around the site.

Closure and Post-Closure Care:

1. Closure: Once the landfill reaches its capacity, it is closed. This involves placing a final cover over the waste to prevent water infiltration and promote vegetation growth.

2. Post-Closure Care: After closure, the landfill site is monitored and maintained for a specified post-closure care period, which is typically 30 years. During this time, the leachate collection and gas management systems continue to operate, and the site is monitored to ensure that it is not posing a risk to the environment or human health.

Construction and Demolition waste landfills play a crucial role in the management of C&D waste, helping to divert these materials from other landfills and promote recycling and reuse.
