Waste Disposal Process and Norms in Bangladesh

The waste disposal process and norms in Bangladesh are managed primarily by a combination of central and local government authorities, with key roles outlined below:

Main Government Authorities

• Urban Local Bodies (ULBs):
  • Includes City Corporations (in large cities like Dhaka and Chattogram) and Municipalities (Pourashavas) in smaller urban areas.
  • Responsible for planning and implementation of solid waste management (SWM) within their jurisdictions, including waste collection, transportation, landfill management, and disposal facility operations.
• Local Government Engineering Department (LGED):
  • Supports capacity-building, infrastructure development, and technical improvements in waste management across Bangladesh.
  • Often acts as the implementing entity for government and donor-funded SWM projects.
• Department of Environment (DoE):
  • Under the Ministry of Environment, Forest and Climate Change.
  • Oversees policy, regulation, and environmental norms related to waste, including hazardous and industrial waste management.
  • Implements national strategies like the 3R (Reduce, Reuse, Recycle) Initiative.

Waste Management Rules and Policies

• Solid Waste Management Rules 2021 standardize processes and responsibilities for municipal waste handling, including waste separation, transportation, and sustainable disposal.
• National 3R Strategy promotes reduction, reuse, and recycling as the foundation for waste management in Bangladesh.

Key Points

• City Corporations and Pourashavas are the main agencies managing solid waste locally, providing infrastructure for collection, transport, and disposal.
• The Department of Environment monitors compliance with environmental norms and leads national waste policies.
• LGED assists with project planning, technical support, and execution of SWM initiatives.
• Government encourages public-private partnerships and community involvement for better waste management results.

Norms and Guidelines for Incinerators in Bangladesh

Regulatory Authority

The Department of Environment (DoE) under the Ministry of Environment, Forest and Climate Change is responsible for issuing environmental clearance for incinerator projects and ensuring compliance with national standards and rules, including the Solid Waste Management Rules 2021.

Key Norms and Guidelines

• Minimum Operating Temperature:
  • All municipal solid waste incinerators must operate at a secondary chamber temperature of at least 1,000°C.
    This is mandated specifically by the Solid Waste Management Rule, 2021. The standard is intended to ensure complete combustion and reduce air pollution, particularly black carbon and toxic organic compounds like dioxins and furans[7].
• Environmental Clearance:
  • Incinerator facilities must obtain environmental site clearance from the DoE before construction and operation. This includes assessment of emissions, effluent management plans, and compliance with national standards for discharges and air quality[7][8].
• Air Pollution Control:
  • Emission standards and air pollution controls are outlined in related rules, including Air Pollution Control Rules 2022[3] and Environment Conservation Rules, 1997[8].
  • Incinerators should include suitable gas cleaning equipment to meet air emission standards for hazardous pollutants.
• Residue Management:
  • Residues (ash) after incineration must be handled properly—typically stored in a concrete pit and kept separate from other solid waste streams. The carbon content in ash is legislatively controlled to be below 5% for safety[5].
• Waste Characterization & Segregation:
  • Waste fed into incinerators should be characterized for moisture and combustible content. For medical waste, double chamber pyloric incinerators operating at 800°-1,250°C are common, with operational guidelines to minimize dioxin generation[5].
• Effluent Management:
  • Effluent discharge standards meet the parameters set in the Environment Conservation Rules, 1997 (BOD, nitrate, phosphate, temperature etc.) before any liquid waste is released to water bodies[8].

Additional Considerations

• Waste-to-energy incinerator projects in Bangladesh are required to follow these country system requirements as part of their environmental and social management plans[9].
• Site-specific emission, environmental, and operational norms may vary for clinical waste incinerators and medical waste streams[5].
