The protesters staged a march in protest of the "toxic" waste-to-energy incinerator and demanded the Delhi Pollution Control Committee to cancel the consent given to it.
"The hazardous waste to energy (WTE) plant and a biomedical waste incinerator nearby have been visibly polluting the environment around Okhla that includes major hospitals such Holy Family, Apollo Indraprastha and Fortis Escorts Heart Care Institute.
"It is also close to some landmark establishments such as the Jamia Milia Islamia, Bahai Lotus temple and the Okhla vegetable market posing a serious threat to public health. They also threaten the flora and fauna of the Okhla Bird Sanctuary and Wildlife Park," a release said.
