Violation of the ban on single-use plastic (SUP) items in Delhi will invite a fine of up to Rs 1 lakh or a jail term of up to five years, Environment Minister Gopal Rai said on Friday. The minister said the Delhi government will issue warning notices to units found violating the ban on 19 identified SUP items till July 10 and thereafter punitive action will be taken against repeat offenders. However, the government will give top priority to creating awareness against the use of SUP items and providing their alternatives to people, he said.
