Can Bhopal waste be safely disposed of?

Note4Students

From UPSC perspective, the following things are important :

Mains level: Hazardous waste;

Why in the News?

The Madhya Pradesh High Court gave authorities four weeks to dispose of the waste, nearly 40 years after the gas disaster that killed over 4,000 people and left thousands more injured or disabled.

What are the plans for the hazardous gas leak waste? 

  • Waste Transportation: The Madhya Pradesh government has successfully transported 358 tonnes of hazardous waste from the Union Carbide facility in Bhopal to the Treatment, Storage, and Disposal Facility (TSDF) in Pithampur, Dhar district, following a court order.
  • Incineration Process: The waste will be incinerated at the Pithampur facility, with an initial timeline of three to nine months for complete disposal, depending on emissions and safety assessments during the process.
  • Emission Controls: To mitigate air pollution, the incinerator will utilize four-layer special filters to ensure that the smoke emitted does not contaminate the surrounding environment.
  • Post-Incineration Measures: After incineration, the resulting ash will be covered with a two-layer membrane and buried in a landfill to prevent any contact with soil and water sources.
  • Expert Supervision: The entire disposal process will be overseen by officials from the Central Pollution Control Board and State Pollution Control Board, ensuring compliance with safety regulations and environmental standards.

How much has been allocated to incinerate the waste and deposit the residue at a landfill in Pithampur?

  • The Central government has allocated ₹126 crore (approximately $15 million) to facilitate the incineration of this waste and ensure that any resulting residue is safely deposited in a landfill at the Pithampur facility.

Why have there been protests?

  • Health and Environmental Fears: Residents are worried that the incineration of toxic waste will pose significant health risks and environmental hazards to the local population and surrounding areas, with claims that it could lead to harmful emissions affecting air quality.
  • Historical Context: The protests are fueled by the legacy of the 1984 Bhopal gas tragedy, which resulted in thousands of deaths and long-term health issues. This history has heightened sensitivity to any activities involving hazardous materials in the region.
  • Community Mobilization: Local organizations, such as the ‘Pithampur Bachao Samiti’, have organized bandhs (shutdowns) and demonstrations, leading to widespread participation from residents who are calling for the waste to be returned to Bhopal instead of being incinerated locally.

What is the 1984 Bhopal gas tragedy?

The Bhopal gas tragedy, also known as the Bhopal disaster, occurred on the night of December 2-3, 1984, at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India.  

  • Chemical Leak: The disaster was triggered by a leak of approximately 40 tons of methyl isocyanate (MIC), a highly toxic gas used in pesticide production. This gas escaped from a storage tank due to a combination of operational failures and safety deficiencies at the plant.
  • Immediate Impact: The gas cloud spread over densely populated areas surrounding the plant, leading to immediate chaos and panic. Official estimates indicate that around 3,787 people died as a direct result of the gas exposure, while other estimates suggest that the death toll could be as high as 15,000 to 20,000 over subsequent years due to related health complications.
  • Injuries and Long-term Effects: Over 558,000 individuals suffered injuries ranging from respiratory problems to permanent disabilities. Many survivors continue to experience health issues related to their exposure to the toxic gas.

Way forward: 

  • Strengthen Public Engagement and Transparency: Conduct comprehensive awareness campaigns involving scientific experts to address community concerns, ensuring transparent communication about safety measures, emission controls, and environmental safeguards during the incineration process.
  • Enhance Monitoring and Compliance: Implement stringent real-time monitoring of emissions and groundwater quality during and after waste disposal, supervised by independent experts and regulatory bodies, to uphold environmental and public health standards.
