Disposal of Treated Toxic Industrial Wastes / Compliant Industrial Wastes at Dumping Ground

Solid residues such as sludge from wastewater treatment facilities and fly ash from waste incinerators may contain toxic contaminants such as heavy metals. Such wastes shall be treated to comply with leachate test standards before disposing of at an approved landfill site.

Application for written permission to dispose of such wastes must be accompanied by a recent report of analytical results from TCLP leachate tests carried out on the wastes. The report must be from a SAC-SINGLAS accredited laboratory. For the list of SAC-SINGLAS accredited organisations, please refer to

Disposal of Asbestos Waste at Dumping Ground

Application of Written Permission to Dispose of Asbestos Wastes at Semakau Landfill

Any person who undertakes work involving asbestos is required to notify the Chief Inspector of Factories by submitting the Notification of Process Involving Asbestos form to the Occupational Safety and Health Division of Ministry of Manpower, at least 28 days before the commencement of such work. More information regarding the handling/removal of asbestos material can be found in the 'Guidelines on The Removal of Asbestos Materials in Buildings at MOM's website.

Contractors who are responsible in removing the asbestos wastes/debris, are then to engage a NEA-licensed asbestos disposal company to clear and transport the asbestos wastes to Semakau Landfill. These licensed disposal companies own barges and have the expertise in handling and barging the asbestos safely to Semakau Landfill.
