QUESTION: What Steps Does the Landfill Take to Minimize Odor?


At Bethlehem Landfill, we understand the importance of implementing robust and effective strategies to manage odors, ensuring that our operations harmonize with the environment and the communities we serve. Below are some of the key measures we have undertaken to mitigate odors, reflecting our dedication to operational excellence and environmental responsibility.

  1. Daily Covering Practices: Bethlehem Landfill covers waste daily with layers of soil or other materials to help contain odors and prevent them from escaping into the surrounding environment.
  2. Waste Compaction: Compacting the waste helps reduce the amount of exposed surface area, which can decrease the emission of odors.
  3. Advanced Gas Collection Systems: Bethlehem Landfill installed gas collection systems to capture methane and other gases produced by decomposing waste. Currently there are 178 installed at the landfill. BLC’s gas collection system not only helps to reduce odors but also allows for the extraction of usable energy.
  4. Utilization of Deodorizing Agents: Bethlehem Landfill use deodorizing agents or odor-neutralizing substances to help mask or eliminate odors using both misting and vapor systems to distribute deodorizers.
  5. Innovative Landfill Design: Modern landfills are designed with liners and leachate collection systems to prevent liquids from seeping into the ground and generating foul odors.
  6. Rigorous Monitoring and Maintenance: Regular monitoring and maintenance of the landfill site are essential to identify and address any potential odor issues promptly. Bethlehem Landfill completes both daily and weekly inspections around the site to help identify problem areas and mitigate issues.

In closing, our approach to minimizing odors is multifaceted, reflecting our commitment to environmental stewardship and being a good neighbor in the Lower Saucon community.
