Kathmandu Metropolitan City has requested everyone to manage the waste by classifying it at the source. Kampa said that when all types of waste produced are taken to the final management site Bancharedanda, the lifespan of that place will decrease, KAMPA will classify the waste at the source and only the rotting waste should be brought to that place.

Ravinman Shrestha, head of the environment management department of the metropolitan city, said, 'If all the waste produced at the 18 local levels of the Kathmandu Valley is taken to the final management place, it can be estimated that its period will end in 15 years. Therefore, to use it for a long time, only classified waste should be brought.'

The practice of sorting waste at source has already started in some of the 32 wards of Kampa. Apart from this, the Kamanpa has requested to start in other wards as well.  Every day, 1,200 metric tons of garbage from Kathmandu valley is being managed in Bancharedanda. In accordance with the Garbage Management Act issued by the government in 2068 and the Environment and Natural Resources Protection Act issued by KAMPA in 2077, the law stipulates that the producer is responsible for separating the waste at the source. 

'There are two types of waste coming out in the kitchen, rotting and non-rotting. Keeping perishables in separate containers and non-perishables in separate containers is a classification. Producers of non-biodegradable waste can sell it themselves. Decomposing waste can also be made into fertilizer," said Shrestha, head of the department.
