Why in news?

      The joint committee appointed by the National Green Tribunal (NGT) to look into the causes of pollution in Ulsoor Lake has asked the civic body to modernise its slaughterhouse on Tannery Road by March 31, 2024.

How is the pollution caused?

  • Untreated discharge from the slaughterhouse directly enters the lake through the drains

Long term measures suggested by the committee

  • Modernisation of abattoir
  • Installation of effluent treatment plant to achieve zero liquid discharge and
  • Biogas plant for solid waste

An immediate short-term measure taken by BBMP

  • Arrangements were made to transport the effluent to the Common Effluent Treatment Plant (CETP).

 THE Challenges

  • the closure of the slaughterhouse would lead to illegal slaughtering of animals in shops and streets, massive discharge of blood and animal waste into drains, illegal selling of uncertified meat to customers, and contamination of the groundwater resulting in environmental pollution.
