Singapore has set a visionary goal of becoming a “Zero Waste Nation.” This ambitious target aims to minimize the amount of waste sent to landfills and incineration plants. However, Singapore has implemented robust waste management strategies and initiatives that have helped to significantly reduce waste and maintain cleanliness. In a bid to become a leading example of environmental responsibility, Singapore’s ambitious zero-waste goal pushes the boundaries of sustainable waste management. Here’s a closer look at their efforts and the roadblocks they face:
As its name rightly suggests, solid waste is basically all unwanted materials that are solid in form. They can be made from anything, including cardboard, paper, wood, plastics, glass, metal, stone, textiles, and even food, and can come from anywhere.
Singapore has a very efficient solid waste disposal system in place to collect, treat, and dispose of all these various types of solid waste, in a way that maximizes space and minimizes environmental impact.
Some key initiatives
- Waste Reduction Targets:
- Singapore aims to reduce the amount of waste sent to landfill per capita per day by 20% by 2026. This effort will accelerate progress towards the 30% reduction target by 2030, as outlined in the Zero Waste Masterplan.
- The master plan focuses on minimizing food waste, packaging waste (including plastics), and electrical and electronic waste (e-waste).
- Deposit Refund Scheme (DRS):
- To address packaging waste, including plastics, Singapore plans to introduce a legislative framework for a Deposit Refund Scheme (DRS) by 2022. This scheme encourages recycling and reduces litter by providing incentives for returning containers and packaging materials.
- Chemical Recycling:
- Preliminary findings from a joint feasibility study by the National Environment Agency (NEA) and Shell indicate that chemical recycling in Singapore is technically feasible. This approach diverts plastic waste away from incineration and results in carbon savings.
- Food Waste Management:
- NEA is exploring a framework for large industrial and commercial (I&C) premises to measure and report the amount of food waste segregated for treatment. This complements existing requirements for large I&C premises to segregate food waste for treatment.
- E-waste Management:
- Singapore will implement an Extended Producer Responsibility (EPR) scheme for e-waste in July 2021. Residents can expect more avenues to recycle their e-waste later this year.
Strategies for a Sustainable Future
- Waste Reduction: Singapore is promoting reusable products, encouraging composting, and educating the public about responsible consumption habits.
- Enhanced Recycling: They’re working to improve recycling infrastructure and increase recycling rates, especially for plastics and e-waste. This includes initiatives like distributing separate recycling bins for households.
- Waste-to-Energy Conversion: While not ideal, incineration helps reduce waste volume and generate electricity. However, Singapore is constantly researching cleaner incineration technologies.
Challenges on the Path to Zero Waste
- Limited Landfill Capacity: Singapore’s Semakau Landfill has limited space, highlighting the urgency of waste reduction and resource recovery.
- Public Awareness: Shifting consumer behavior towards waste reduction requires ongoing public education and promoting a culture of sustainability.
- Alternative Solutions: Finding more sustainable solutions for waste treatment beyond incineration is crucial, and Singapore is exploring advanced recycling technologies.
Overall, Singapore’s zero-waste goal is a commendable and necessary endeavor. Their focus on waste reduction, improved recycling, and responsible waste-to-energy conversion demonstrates a commitment to a sustainable future. However, achieving this goal requires continuous efforts to address landfill limitations, promote public awareness, and explore cleaner waste management solutions.

Frequently Asked Questions (FAQs)
A. Singapore’s integrated solid waste management system focuses on two key thrusts: waste minimization and recycling, commonly referred to as the 3Rs (Reduce, Reuse, Recycle). In a land-scarce environment like Singapore, waste-to-energy (WTE) incineration plants play a crucial role by efficiently reducing waste volume and conserving landfill space.
A. Singapore’s economy has been growing rapidly, resulting in increased waste generation. In 2022, approximately 7.4 million tonnes of solid waste were generated, marking a 6% increase from the previous year. This trend is closely tied to economic growth.
A. Singapore has a highly efficient solid waste disposal system managed by three private companies. The system collects, treats, and disposes of various types of solid waste, maximizing space utilization and minimizing environmental impact.
A. Unlike some countries that require households to separate recyclables into different bins, Singapore simplifies recycling by having just two types of household trash cans: recyclable and non-recyclable. This straightforward approach aims to encourage responsible recycling practices.
A. With a growing population, waste generation is expected to increase. Two key areas targeted to address this challenge are waste reduction and efficient waste management processes.
A. A significant portion of Singapore’s waste is incinerated in high-temperature facilities. This reduces waste volume and generates electricity.
A. Reduce waste generation, embrace reusable products, recycle diligently, and support sustainable practices!
