But waste composition is more or less different in urban areas. Increasing population density is the leading cause of solid waste management problem in urban domain of Nepal. However, there is a lack of data on solid waste management in the country. The collection and disposal of solid waste is not satisfactory. Most of the municipalities have been dumping their wastes in nearby river or in open fields and there is lack of sanitary landfill sites to dispose of generated wastes.
Some municipalities do practices compost preparation from collected biodegradable waste.
The term solid waste refers to low liquid content waste materials. The higher the level of economic development, the greater the proportion of non-biodegradable materials in waste composition. So, solid waste is not a serious problem in agricultural rural economy compared to urban areas. Solid waste generation is directly related to population density. In small rural communities with low population density, natural systems are able to absorb domestic waste.
