Waste Management

The way we generate, treat and dispose of waste has a strong impact on the environment and community-at-large. Waste breakdown in landfills contribute to carbon emissions and leachates may contaminate groundwater and waterways, while incineration causes pollution issues and affects air quality.

CDL remains steadfast in managing our waste efficiently and seeks to reduce, reuse, and recycle our waste whenever feasible. As a property developer and manager, the bulk of the waste is generated by our builders and commercial tenants. Unless re-used, demolition at the end of a building’s life cycle can produce significant waste for land disposal. To mitigate our impact on the environment, CDL has several strategies to practise the 3Rs in waste management:

Waste Management Method Initiatives Benefits
Adoption of Prefabricated Prefinished Volumetric Construction (PPVC) technology for large-scale residential development Generates less waste and paves the way for cleaner and safer construction sites
Construction and Demolition Waste Policy since 2009 for the adoption of sustainable construction practices Leads to builders’ increased use of sustainable products and improved recycling rates for construction waste
Reuse furnishing used in our show flats wherever the design or theme permits Reduce waste generated and costs required to re-purchase materials
Identify materials for reuse or recycling under BCA’s Demolition Protocol  
Recycling programme for light bulbs Reduce land pollution by diverting mercury away from landfills
Recycling programme for commercial buildings and CDL corporate office Reduce waste sent to incineration plants and use of natural resources

In land-scarce Singapore, most of the general waste is sent to the waste-to-energy incineration plants. Incineration plants are capable of reducing the solid waste volume by 90%, and the incinerated ash is then transported to the landfill for disposal. Mindful that construction debris cannot be incinerated and are directly sent to the landfill, we are spurred to continuously invest, innovate, and adopt leading-edge technology such as PPVC to significantly reduce construction waste.

All of CDL’s generated waste at both the construction sites and managed buildings is non-hazardous and disposed of in accordance with the National Environment Agency’s (NEA) waste regulations.

In 2016, construction waste generated at all CDL construction sites amounted to 13,523 tonnes, with a waste intensity of 70 kg/m2. This is higher than the previous years as many of our construction projects in 2016 were nearing completion for handover to the homebuyers.

Waste Disposed of and Recycled at CDL Commercial and Industrial Buildings

In CDL-managed buildings, around 4,283 tonnes of general, non-hazardous waste were disposed, with about 704 tonnes of recyclable waste collected in 2016. 83% of the recyclable waste collected was paper.

Our paper recycling programme has seen increasing tenant participation from 68% in 2005 to 100% in 2016. Although lamps contain trace amounts of mercury, lamps that are available for sale in Singapore can be disposed of safely as general waste and thus not considered as hazardous. However, as a responsible corporate citizen, CDL actively collects lamps for recycling to conserve natural resources and to reduce contamination by mercury. Under the lamp recycling programme with Global Lamp Recyclers, 15,836 lamps weighing more than 1,753 tonnes were recycled in 2016.
