A bench headed by NGT Chairperson Justice Swatanter Kumar, which did not pass any observation, said the AAP government should find out ways to get rid of the non- biodegradable material.
The green panel observed that such a huge quantity of plastic could also be sent to waste-to-energy plants for scrapping.
The matter is posted for hearing on September 5.
Earlier, the city government had said that a sum total of Rs 3 lakh has been collected as fine following the prohibition imposed by the green panel.
"According to reports submitted by various departments, a total of 7,739 kg of plastic carry bags (less than 50 microns) has been seized, 492 challans have been issued and a total of Rs 2.9 lakh has been realised as environment compensation," the government had said in a statement.
The NGT had directed the Delhi Pollution Control Committee and other authorities to seize the entire stock of such plastic within one week from the day of the ban.
