WHB’s expertise in this area includes the design, construction, operation, closure, restoration and after care of landfills, including the post-operation extraction of resources from a landfill.

In Selangor, we operate two strategic landfill at Tanjung DuaBelas Kuala Langat and Jeram Kuala Selangor.

Small collection vehicles and larger compactor unload their waste at the landfill. The waste is then placed, compacted and covered to reduce odor and the ingress of water, utilizing specified equipment to maximize efficency and ensure safety.

Our landfills are designed to comply with the highest Department of Environment requirement. The design includes a secure liner system and a cap to prevent water ingress and gas engress. Drainage system are also built within the landfill to collect liquid effluent (leachate) that are further treated in special designed treatment plant.

Within the waste mass, the degration of waste generates landfill gas, which is collected through system of pipes and wells. A naturally recovered energy, the gas then beneficially used to generate thermal energy or electrical power.
