Solid Waste

Solid Waste

                       The levels of socio-economic development determine the quantity and composition of solid waste. Higher the level of economic development, greater the proportion of waste composition. The total population of the city is 1,32,836, among those, 90% population is predominantly tribal. Hence, solid waste is not that much problem in rural economy compared to urban areas. As a result of that, the problem of municipal solid waste management is not yet felt in the rural areas of Nagaland. Compared to that, the concentration of population with higher densities in Kohima towns as well as unmanaged growth of settlements are among major causes leading to the problem of municipal solid waste affecting public health and natural environmental systems. So the total elimination of the waste is an impractical suggestion, rather than it should be managed in an effective manner

                         In Kohima, the responsibility of the waste management lies with the Kohima Municipal Council (KMC). The present system of municipal solid waste management gives a broader view of the entire system. in 2010, the amount of waste generated from the Kohima city is around 54 MT per day. Out of this, around 35-40% of wastes are collected from the entire city as per the data available.

                       The total area of the disposal site is about 56.53 acres located at the southeast of the city. All municipal wastes are dumped on a sloping site about 8 km from the city. Wastes are generally dumped in open streams or burnt in empty spaces. The Siste Ru river flows just below the disposal site and, as a result, the majority of dumped wastes accumulate in the river. Huge amounts of biomass, suited for use in soil nourishment to increase fertility, are lost through the burning of wastes. Frequency rates for irregular disposal are high. Almost 49% of the population is served by an unofficial service, whereas only 31% by the official service. Wastes are collected on a weekly/ Waste generating sources Proportion of wastes (%) Residential 57.00 Commercial (markets, shops, etc.) 19.00 Institutional (offices, banks, colleges, schools, etc.) 15.50 Industrial 3.00 Biomedical wastes in hospitals and nursing homes 0.50 Construction and demolition wastes 5.00          

                     Wastes are collected on a weekly/biweekly basis and in regular/irregular manner. The disposal of biomedical waste is usually carried out by open burning at the disposal site using old tyres. Processing or recycling procedures are not currently applied in Kohima. The only recycling performed is carried out to some extent by rag pickers exposed to harsh, unprotected conditions

   Nagaland state's first of its kind Solid Waste Management Facility located was inaugurated on February 11 , 2016 at Lerie.The project was taken up as a part of the North Eastern Regional Capital Cities Development Investment Program (NERCCDIP),Government of India, through the Ministry of Urban Development (MoUD) with State Investment Program Management Implementation Unit (SIPMIU) Nagaland as the Implementing Agency. The loan assistance for the facility was provided by the Asian Development Bank (ADB).


   The facility consist of a compost plant able to generate manure at 50 tons/day from the biodegradable wastes, and a landfill which is designed to accommodate 32000 cubic meter of wastes .The facility also includes electrical substation and diesel generator back up, rain water harvesting tank etc. It further includes vehicles/equipment including tractor mounted excavators with dozing attachment, backhoe with front end loader, vibratory roller, skid roller and tipper truck etc.


   The Solid Waste Management Facility in the state is considered to be first of its kind in the northeast region.
