Waste Management


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 in, innovate, and adopt leading-edge technology such as Prefabricated, Prefinished Volumetric Construction (PPVC) to significantly reduce construction waste.

All of CDL’s generated waste at both the construction site and managed buildings is non-hazardous and disposed of in accordance with the local waste regulations.

Waste Management Hierarchy

CDL remains steadfast in managing our waste efficiently and seeks to reduce, reuse, and recycle (3Rs) our waste whenever feasible. As a property developer and manager, the bulk of the waste is generated by our builders and commercial tenants. Demolition at the end of a building’s life cycle can produce significant waste for land disposal, unless materials are reused or recycled. To mitigate our impact on the environment, CDL has several strategies in place to practice the 3Rs in waste management.

Waste Reduction Target and Performance

Following the principle of the 3Rs, CDL set to reduce total waste intensity by 50% from 2016 levels. In 2017, we achieved 8.0% reduction, below the 10% interim target we set for the year.

In CDL-managed buildings, around 4,265 tonnes of general, non-hazardous waste were disposed in 2017. About 599 tonnes of recyclable waste was collected in 2017, 80% of which was paper. Our paper recycling programme has seen growing tenant participation from 68% in 2005 to close to 100% in 2017.

In 2017, construction waste generated at all CDL construction sites amounted to 3,796 tonnes, with a waste intensity of 60 kg/m2. This is a reduction from 2016.

Moving forward, we will continue to be vigilant on our waste management. We will be reviewing our waste minimisation and recycling practices as we work towards achieving the 2030 target.
