Skips are excellent for getting rid of most things, however for legal or practical reasons there are several items and materials that cannot be put into a skip, and must therefore be disposed of separately. DA Engineering Pte. Ltd is committed to comply with all the laws and regulations in Singapore.

List of Accepted Wastes
The following are the only type of wastes that can be accepted and disposed by the company:
• Construction wastes

• Electrical appliances
• Wastes that can be recycled (except food waste)
• Household or garden wastes

Please be aware unless you have notified us prior to ordering, an extra disposal fee will be charged if unsuitable waste is found in a skip, including a charge from Da Engineering Pte Ltd of up to $2,000 to cover labour/specialist disposal costs. We reserve the right to not collect a skip we believe contains unauthorised waste or return such items if found including labour/haulage cost.
To learn more about all these things, do not hesitate to contact our company. Our staff will be more than willing and happy to assist you. For more information on unauthorised waste, please visit NEA website at http://www.nea.gov.sg/energy-waste/waste-management

Below are some items which you may find helpful.

Asbestos Must Never Be Mixed with Other Waste in A Skip
Asbestos in skips is a big "NO".
You must never put asbestos in a skip; it is hazardous and harmful, and the government has implemented certain laws which mean it’s illegal to reuse and recycle any asbestos material, or to dispose of it improperly. Asbestos must be removed by a specialist asbestos removal contractor. Your local council should always be your first port of call – if they don’t provide their own collection service, they will know of companies in your area that do. Alternatively go to http://www.nea.gov.sg/anti-pollution-radiation-protection/chemical-safety/hazardous-substances/control-of-asbestos-in-singapore

Avoid putting plasterboard and gypsum waste into the skip – it’s not allowed, unless it is purely a plasterboard skip even then please call us for more information and help if still unsure.
Plasterboard is high sulphate and gives off colourless gases that are harmful to the environment and must not be mixed with low bearing waste.
Gypsum waste must be landfilled, specific Environment Agency rules control it. As a non-hazardous high-sulphate waste, there is a risk that large volumes of gypsum waste mixing with rainwater and organic waste materials could produce hydrogen sulphide, therefore it is not permitted in mixed waste but must be landfilled in dedicated, non-hazardous ‘high sulphate’ landfill cells, which minimise impact on the environment. These cells are a potential exploitable source for recycled gypsum for the future.
Government initiatives are aiming to recycle most plasterboard and gypsum waste, so it needs to be taken to specialised recycling plants, which you can find on the NEA website, at http://www.nea.gov.sg/anti-pollution-radiation-protection/chemical-safety/multilateral-environmental-agreements/annex-ix

Batteries
No type of battery can be put in any skip. Batteries contain various metals and chemicals which mean they must be treated separately, so don’t put batteries into the skip, even small ones.

Medical Waste
Medical waste must not be disposed of in a general waste skip – it risks infection and contamination, and needs to be dealt with by certain, licensed agencies. Anything from used or unused needles to biological waste needs special treatment and is not suitable for skips. Contact http://www.nea.gov.sg/anti-pollution-radiation-protection/chemical-safety/toxic-industrial-waste/toxic-waste-control for guidance on the proper disposal of medical waste.

Gas Cylinders
We will not take gas cylinders, whether full or empty. Residual contents of a gas cylinder are potentially dangerous and we are not licensed to remove them. Try contacting the company who provided the gas cylinder as they are often happy to collect used cylinders for reuse and recycling. More information on disposing of gas cylinders can be found at http://www.nea.gov.sg/anti-pollution-radiation-protection/chemical-safety/toxic-industrial-waste
