New Delhi: Aiming to reduce pollution at construction sites, the government has adopted the "Metro model" in drafting its new solid waste management rules, Union Environment Minister Prakash Javadekar said on Friday.

He said the Narendra Modi-led government was leading by example when it came to the environmental front and that it has attracted the attention of leaders across the globe. The minister was speaking at a national-level conference on Green Metro Systems here organised jointly by the Delhi Metro Rail Corporation and industry body CII.

"We have adopted the DMRC or the 'Metro model' on solid- waste management. E-waste, hazardous, plastic waste rules have been put on the Environment Ministry's website for public consultation. All suggestions are welcome till July 21," the minister said.

He was also effusive in his praise of Delhi Metro's "work culture" and hailed the rapidly expanding network's careful consideration of environmental issues during construction work. DMRC MD Mangu Singh was also present on the occasion.

"Felling of trees is an imperative for construction activities. Music is born out of force. This is the rule of nature. But that doesn't mean trees can't be translocated. Metro has shown the way here also by successfully translocating trees," he said.
