NEA’s Vision and Strategiesfor a Zero Waste Nation

One of the objectives of the Sustainable Singapore Blueprint is to work towards Singapore becoming a Zero Waste Nation.

Our aim is to reach an overall recycling rate of by 2030.

To meet the objective for a Zero Waste Nation and conserve our precious resources, Singapore has adopted the following waste management strategies:

70%

Minimisation / Prevention

Recycling

environmental sustainability

Landfill

Waste-To-Energy / Volume Reduction

Overview of Waste Management System in Singapore

energy (WTE) incineration plants.37%

Incineration has enabled us to reduce the volume of waste by .60% 3%

90%

The amount of electricity generated by the 4 WTE plants meets up to of Singapore’s total electricity demand.
