Technical Guidelines on Solid Waste Management in Sri Lanka

Introduction

  • Prepared by Hazardous Waste Management Unit, Central Environmental Authority (CEA).

  • Focus on improving solid waste disposal practices in Sri Lanka.

Page Overview

  • Page 1: Title and contact information for CEA.

  • Page 2: Chairman's Message on the importance of waste management and current challenges in Sri Lanka.

    • Issues include illegal dumping and lack of public awareness.

    • Guidelines aim to provide technical support for effective waste management.

  • Page 3: Director General's Message.

    • Acknowledged the public's demand for proper waste disposal vs. their reluctance to participate.

    • Document outlines guidelines for waste collection, transportation, incineration, and environmentally friendly disposal.

  • Page 4-5: Acknowledgments to individuals and organizations involved in the preparation of these guidelines.

  • Page 6: List of tables and annexures providing detailed guidelines and specifications.

  • Page 7: Contents overview for upcoming sections on waste management.

Preamble (Page 8)

  • Municipal Solid Waste (MSW) is a major issue in urban areas due to poor management systems.

  • Common mishaps include mixing waste and dumping in sensitive environments causing pollution.

  • Guidelines focus on promoting waste avoidance, reduction, recycling, and proper disposal.

Target Solid Waste (Pages 9-11)

Types of Waste:

  1. Municipal Waste:

    • Domestic, commercial, and institutional waste.

    • Includes street sweeping and garden wastes.

  2. Construction Waste

  3. Industrial Waste: Non-hazardous waste accepted in municipal landfills.

General Guidelines (Pages 11-12)

  • Emphasis on source separation and recycling.

  • Legal compliance with existing laws and regulations from CEA.

  • Commitment to minimize pollution and protect the environment through appropriate waste management procedures.

Waste Collection (Pages 12-14)

  • Introduction: Waste collection at various sources is a fundamental element of waste management.

  • Information required for operation includes:

    • Collection areas, vehicle types, routes, and schedules.

  • Design Requirements for collection vehicles to prevent leaks and littering.

  • Operational Requirements: Maintain records and avoid collecting hazardous waste.

Transfer Stations (Pages 14-15)

  • Transfer stations are pivotal for transferring waste to larger vehicles for processing or disposal.

  • Requirements include:

    • Proper capacity and design for storage, unloading, and traffic management.

  • Maintain records of the quantity of waste received and transferred.

Materials Recovery Facility (Pages 15-17)

  • Facilities established for further separation and processing of recyclables.

  • Design focuses on efficient sorting and processing of materials.

  • Compliance with environmental standards during operations.

Incineration Facility (Pages 17-20)

  • Controlled burning of waste to minimize landfill usage.

  • Requirements for combustion efficiencies and emissions monitoring.

  • Emphasis on air pollution control measures.

Composting Facility (Pages 20-22)

  • Biological decomposition of organic waste to produce compost.

  • Factors to consider include method, processing time, and design requirements for ventilation and odour control.

Anaerobic Digestion and Biogas Production (Pages 22-23)

  • Anaerobic processes turning highly organic waste into bio gas for energy.

  • Essential design and operational requirements to safely handle waste.

Landfill Facility (Pages 23-26)

  • Guidelines for proper engineering of landfills to minimize environmental impact.

  • Waste classification and rejects management emphasized.

  • Regulations for landfill sites focus on location, design, pollution control, and post-closure care.

Annexure Information (Pages 27-38)

  • Annex A: Proposed color codes for garbage bags to improve waste separation awareness.

  • Annex B: Regulations for effluents and leachate quality compliance standards.

  • Annex C: Specifications for compost quality from municipal and agricultural wastes.

  • Annex D: Guidelines for selecting and operating solid waste disposal sites.

Compliance and Operational Requirements

  • Regular monitoring and compliance with environmental standards is necessary across all the proposed facilities.

  • Feedback from local authorities and public engagement in waste management crucial for success.
