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 principles of a circular economy, CDL is committed towards waste minimisation and resource efficiency throughout our development sites and managed buildings. Come 2030, CDL targets to reduce total waste intensity for our corporate office and managed buildings by 7% from 2016 levels.

In CDL-managed buildings, around 4,084 tonnes of general, non-hazardous waste were disposed in 2018. About 693 tonnes of recyclable waste was collected in 2018, 84% of which was paper. Our paper recycling programme has seen increasing tenant participation soar from 68% in 2005 to nearly 100% in 2017.

In 2018, construction waste generated at all CDL construction sites amounted to 1,345 tonnes, with a waste intensity of 30 kg/m2. This is a reduction from 2017 and meets the 2018 waste targets set for Property Development, on track to achieve the 2030 target of 30kg/m2.

Moving forward, we will continue to be vigilant of our waste management practices. With 2019 being designated as the Year Towards Zero Waste for Singapore and increasing focus on a circular economy, this year is a timely opportunity to review our waste minimisation and recycling initiatives, as well as to engage our stakeholders for the achievement of our 2030 targets.
