The Municipal Corporation of Delhi will "continue to do" as mandated by the Central Government norms on ban on single-use plastic (SUP), even as the city government has said it will grant a 10-day grace period to units found violating the ban before initiating punitive actions.

Civic authorities on Friday had seized nearly 689.01 kg of plastic items and issued over 368 challans in its jurisdiction in view of the countrywide ban on SUP.

"These items were largely seized from traders in markets who keep a stock of plastic bags. Once the ban has come into place, markets are switching to paper bags or cloth bags, as expected," a senior official said on Saturday.

"It was just day one of the ban kicking in. We are raising awareness from our sides, as also other necessary steps will be taken accordingly in the coming days," he said.

However, Environment Minister Gopal Rai on Friday had said that the Delhi government will issue warning notices to units found violating the ban on 19 SUP items till July 10 and punitive action will be taken thereafter against repeat offenders. Another senior MCD official when asked if MCD would continue to take action against such violators, said, "We will continue to do in accordance with the Central Pollution Control Board (CPCB) and central government norms on the ban on single-use plastic".

"The MCD is conducting ICE (information, communication and education) activities anyway to raise awareness and steps will be taken according to the norms," he said. "A total of 125 enforcement teams have been constituted at zonal level to eliminate stocking, sale and usage of banned items," it said.
