The National Green Tribunal (NGT) directed the Mizoram government to lodge a new, detailed report on solid and liquid waste management after finding serious deficiencies in an earlier submission. The previous report did not carry certification by a senior state official, and lacked timelines, fund allocations, executing-agency details and clear data on door-to-door segregated collection. It found that Mizoram generates about 398.15 tonnes of solid waste per day, of which 67.65 tonnes remain unprocessed, and produces 51.81 million litres per day of sewage while treatment capacity is much lower. The NGT asked for a revised Action Taken Report (ATR) that covers generation, collection, processing gaps, fund allocation and timelines, with a filing due ahead of the next hearing.
The NGT's Principal Bench, chaired by Prakash Shrivastava, held a hearing regarding the state's compliance with the Municipal Solid Waste Management Rules, 2016 and related environmental obligations. The bench observed that the state's status report was not filed as an affidavit of the Chief Secretary or any senior state secretary, raising serious concerns about the accuracy of the data submitted.

According to the tribunal's examination, Mizoram generates about 398.15 tonnes per day (TPD) of solid waste, of which only 330.5 TPD is being processed, leaving around 67.65 TPD unprocessed and contributing to legacy waste. The report also lacked credible information on door-to-door segregated collection and transportation by the 28 Urban Local Bodies (ULBs) in the state.
On liquid waste management, the tribunal noted that Mizoram produces around 51.81 million litres per day (MLD) of sewage 31.37 MLD from urban areas and 20.44 MLD from rural areas while available treatment capacity in Aizawl stands at just 10 MLD, leaving an urban gap of 21.37 MLD. Further, out of the state's 11 districts, plans for sewage treatment in 10 districts have not yet been finalised, and a proposed 27 MLD treatment capacity has no set timeline for implementation.
Given these findings, NGT has directed the state government to submit a revised ATR that includes: solid waste generation, collection, transportation, processing, legacy waste figures, gap analysis, timelines, fund allocations; as well as a comprehensive report on sewage management covering generation, conveyance, treatment capacity, gap analysis and utilization of treated water. The tribunal specified that funds must be allocated to each ULB and executing agency, and work plans must be finalised and disclosed. The filing must be made via e-filing as an affidavit at least one week before the next hearing scheduled for early November.
Historically, the solid waste management rules of 2016 require states and ULBs to ensure scientific collection, segregation, transportation, processing and disposal of municipal solid waste, and to report compliance periodically. Mizoram's earlier action plans and compliance reports had flagg
