How Singapore Handles Six Million Pounds of Trash Daily | WSJ A to B

Introduction

This tutorial explores Singapore's innovative waste management system, which efficiently handles six million pounds of trash daily. As the population grows, Singapore faces increasing waste challenges. This guide outlines the key processes involved in their waste management strategy, including trash collection, incineration, and landfill management.

Step 1: Understanding the Waste Management Infrastructure

Singapore's waste management relies on a combination of advanced facilities and strategic planning:

• Waste-to-Energy Plants: These plants incinerate waste to generate energy, significantly reducing the volume of trash while producing electricity.
• Landfills: Currently, Singapore operates one primary landfill, the Semakau Landfill, which is crucial for managing residual waste after incineration.

Step 2: Efficient Trash Collection

The process begins with a systematic trash collection strategy:

• Collection Schedule: Waste collection is organized into a regular schedule, ensuring all areas are covered efficiently.
• Segregation at Source: Residents are encouraged to separate recyclables from general waste, which aids in reducing the amount of trash sent to landfills.

Step 3: Transferring Incinerated Ash

After incineration, the waste is transformed into ash, which is then handled carefully:

• Transportation: The ash is transported to the Semakau Landfill for disposal.
• Monitoring: Continuous monitoring is essential to ensure environmental safety during ash transfer and landfill operations.

Step 4: Managing the Semakau Landfill

The Semakau Landfill is a unique facility that exemplifies Singapore’s commitment to sustainability:

• Landfill Design: The landfill is designed to minimize environmental impact and is located offshore to reduce space constraints on the main island.
• Ecosystem Conservation: Efforts are made to preserve the surrounding marine ecosystem, demonstrating the country’s commitment to balancing waste management and environmental protection.

Conclusion

Singapore’s waste management system is a comprehensive approach that includes efficient collection, incineration, and strategic landfill use. Understanding these steps can provide insights into sustainable practices that other countries can adopt.
