The Lalitpur Metropolitan City (LMC) has asked the federal government to take the lead in establishing a waste processing plant. Writing a letter to Prime Minister Pushpa Kamal Dahal 'Prachanda' on Wednesday, LMC Mayor Chiri Babu Maharjan said that a processing plant was a must to solve the problem of legacy waste at the Okharpauwa landfill site and to generate electricity, gas and fertiliser from the disposed garbage. Legacy waste are the waste materials that have been collected and kept for years at some dedicated place. Talking to The Rising Nepal on Thursday, Mayor Maharjan said that this proposal was based on the learnings and observations he made during his recent trip to India. Maharjan led an LMC team to India from November 1 to 11 at the invitation of the Indian government. There, he visited New Delhi, Ahmedabad, Indore, Pune and Gorakhpur and gathered information about waste management, traffic management, road infrastructure, public security and good governance.
