Landfills play a significant role in waste management, but their impact on the environment cannot be ignored. To mitigate the potential risks, proper rehabilitation and capping works are crucial.
Passive Landfill Gas System: Preserving Air Quality
Jensen Landfill's rehabilitation project includes the installation of a state-of-the-art passive landfill gas system. This system effectively manages the emissions of methane and other harmful gases, protecting the air quality in the surrounding areas.
Site Earthworks and Profiling
By carefully reshaping the land, Jensen Landfill is creating a more harmonious and visually appealing landscape. The strategic placement of soil and material on the site ensures proper drainage and prevents erosion, further enhancing the overall environmental integrity of the area.
Installation of Double-Sided Textured LLDPE
Jensen Landfill's commitment to long-term sustainability is reflected in the choice of materials used during the capping works. The installation of double-sided textured Low-Density Polyethylene (LLDPE) liner acts as a durable barrier, preventing the release of gas and protecting the surrounding ecosystem.
Subsurface Drainage Geocomposite
Managing water flow within the landfill is crucial to prevent potential leachate leakage. Jensen Landfill's rehabilitation project incorporates subsurface drainage geocomposite, a cutting-edge technology that efficiently collects and transports excess water away from the site, preventing it from seeping into the surrounding soil.
Leachate Interception Trench, Sump, and Perimeter Bund
To safeguard local water sources from potentially harmful leachate, Jensen Landfill has implemented an advanced leachate interception system. The combination of a carefully designed trench, a sump, and a perimeter bund ensures that any leachate generated within the landfill is efficiently collected and properly treated.
Stormwater Control Bunds
In alignment with environmental regulations, Jensen Landfill's rehabilitation project features stormwater control bunds. These bunds effectively control and manage the flow of stormwater, preventing pollution and erosion.
300mm Cover Soil
An essential component of landfill rehabilitation is the application of a sufficient cover soil layer. Jensen Landfill utilises a 300mm cover soil, responsibly sourced and carefully distributed across the site.
In line with Jensen Landfill's commitment to sustainability, a 200mm topsoil layer is applied as the final step of the capping works. This layer supports the growth of vegetation, promoting ecological balance and enhancing the aesthetics of the rejuvenated site.
