Disasters can generate large volumes of debris and waste depending upon the nature and severity of it (Brown et.al, 2011). Nepal was hit with a powerful Gorkha Earthquake in 2015 April. Kathmandu, City was severely affected, causing large damages on building structures. Estimation of debris quantity is important to carry out quick emergency debris operation appropriately (Asari et. al, 2013).
Kathmandu Metropolitan City (KMC) generates 466.14 tons of municipal solid waste (MSW) daily with average per capita generation rate of 0.464 kg/c/d. Organic fraction of MSW in KMC is about 64.24% (ADB, 2013). Disaster generated waste is another major problem for highly disaster susceptible city like Kathmandu. An integrated plan for management of MSW and disaster waste might provide effective solution in KMC. Composting of organic waste and planning of effective collection/treatment of disaster waste in decentralized unit and area-wide facilities can reduce the landfilling quantity of waste. The purpose of the study is to identify the proper MSW and debris waste management in KMC.
