Williamson County, Tennessee – A Model of Landfill Modernization

One of the earliest and most successful implementations of the ALBS (Aerobic Landfill Bioreactor System) was in Williamson County, Tennessee. This landfill was originally a conventional anaerobic site, plagued by issues such as high methane emissions, leachate management challenges, and slow waste stabilization. In 2000, TGD Environmental retrofitted the landfill with the ALBS technology, transforming it into a state-of-the-art aerobic bioreactor.

• Results:
  • Methane Reduction: The ALBS technology reduced methane emissions by over 80%, significantly lowering the site’s contribution to greenhouse gas emissions.
  • Improved Leachate Quality: The aerobic process reduced the toxicity of leachate, making it easier and less expensive to treat before discharge.
  • Accelerated Waste Stabilization: Waste volume decreased rapidly due to accelerated decomposition, resulting in a 30% increase in available landfill space.
  • Community Impact: The local community benefited from reduced odors, lower health risks, and the potential for land reclamation.
