The ban on disposable plastics has not been implemented in the city owing to the lack of effort by the civic body, Mumbai-based environmentalist Stalin D alleged in his letter to the Municipal Commissioner Pravin Pardeshi on May 30. The BMC had last year assured the high court-appointed Wetland Committee that it will install nets at the mouth of nullahs and creeks to prevent plastic from entering the sea. Over a year later, it has not been done, Stalin said.

The director of NGO Vanashakti has said in his letter, "Street vendors continue to use plastic bags and no check is in place. The use is more in the evenings after BMC office hours. The vigilance teams need to work at night to curb the menace effectively. This will help reduce the amount of plastic finding its way into the marine ecosystems and landfills. We request you to instruct the formation of teams that will work after 5 pm till 11 pm."
