TESTING FOR WDS
Hazardous waste poses a significant risk and danger to humans, properties and to environment if not managed properly. In accordance with this threat, the Waste Management Department (WMD), Dubai Municipality (DM) published several guidelines to regulate the handling, storage, and preparation of hazardous waste for transportation to disposal sites. This covers the responsibility of the individual/company generating the wastes in accordance with the local and federal laws and in relation with the Basel Convention and International Treaty.
The application for permits to dispose of hazardous waste is made by online submission of request/application through the Waste Disposal Service (WDS) system – one of the many e-services of Dubai Municipality. The WDS can be accessed at the Dubai Municipality’s website – www.dm.gov.ae – upon log-in with a business user ID and password. The WDS system conveniently allows applicants to file disposal request 24/7, views request status, including online payment of disposal charges and for printing on-line WDS Permit upon approval.
Scope and Coverage
- Technical Guideline No. 8 Disposal of Hazardous Waste is applicable to all hazardous waste resulting from a legal or authorized business activity of a person, party, organization or of industrial or commercial establishment that is duly registered or licensed to operate in the Emirate of Dubai including Free Zone areas.
- It also applies to other governmental organizations that, in one way or another, are related to the generation and control of the hazardous waste material.
Application for the Disposal of Hazardous Waste
- Total amounts of waste to be declared in the disposal request shall be in metric tons estimated for the wastes already accumulated plus waste to be generated for next three (3) months, since permit once approved will be valid for Three (3) months only. There is no possibility of validity extension in case the paid permit remained unused or partially used after the permit expiry.
- Any company that will generate or has history of generation of at least or more than 300 m3/year (12 months) of hazardous wastewater will be required to install an onsite wastewater treatment plant (WTP). Otherwise, waste generators have the option to subcontract the treatment of liquid hazardous waste to a private 3rd party Company that has an approved facility for the activity of Wastewater & Hazardous Liquids Treatment. A “WDS Permit” is required to transport the liquid waste to a 3rd party facility. Wastewater that exceeded the sewer discharge limit as presented in Annex 3 shall be neutralized at the source to a non-corrosive state.
- Exact address of the facility where wastes are generated and stored shall be specified in the waste location details in the application.

Instructions and Required Attachments for Specific Type of Wastes
- Pharmaceuticals, drugs – a Medicine Disposal Certificate approved from Ministry of Health for expired pharmaceutical products generated from drug distributor and traders.
- Medical Wastes – Collection, handling, and disposal procedure of medical/clinical waste are explained in the Code of Practice on the Management of Medical Wastes from Hospitals, Clinics, and Related Health care Premises in Dubai (1997).
- Aerosol or pressurized containers – Aerosol or any pressurized containers in general cannot be disposed of in the landfill due to their explosive/flammable nature. These types of containers shall first be fully depressurized and punctured safely. Supporting photos that the requirements were properly adhered to shall be attached in the WDS application. Expired aerosol products shall be sent back to the manufacturer for processing or to a DM accredited waste processing facility.
- Asbestos contaminated materials – Attach photos of the wastes which will be handled as per the Technical Guideline for Safety in Handling Asbestos.
- Flammable Wastes – Provide a separate disposal request for chemicals with a flash point of below 60°C. The flash Point can be found in the MSDS and/or through a Flash Point analysis by a DM accredited laboratory.
- Chemical Wastes – Chemical wastes shall be segregated and applied separately based on their compatibility in the WDS which is categorized according to waste type (e.g. flammables, acids, alkalis, oxidizer, and/or by reactivity). Incompatibles are those pairs of substances that, when mixed, will either react violently or emit flammable or poisonous gases or vapors. Compatibility information is available on the MSDS of the chemical.
- Sludge – sludge shall be dewatered to spadable consistency and with no free liquid. Sample collection for laboratory analysis shall be conducted only when the sludge condition has been met.
- Empty Chemical Containers – Empty tin cans must be pressed/flattened in the waste generator site prior to collection for transport to designated disposal site.
- Waste from Vessel or Ship in Port – Waste coming from Vessel/Cruise Ship arriving in any port of Dubai shall attach Advance Notification Form for Waste Delivery signed by the captain of the vessel or ship and by the Port Reception Facility.
- Waste from Jebel Ali Free zone Companies (JAFZA), Technopark, and Dubai Ports – Attach Trakhees Approval and Inspection Report for each disposal request made online.
