Converting Urban Waste into Energy in Kathmandu Valley: Barriers and Opportunities

Abstract

The population explosion, rapid urbanization rate and the increase in economic activities in Kathmandu Valley have created serious problems in various aspects, including solid waste management and energy deficiency. Despite the existence of distinct link between waste and energy, the “waste to energy” concept is still viewed as an inferior method in Nepal. The government and other concerned stakeholders pay more attention towards the development of hydropower, the major source of electricity production in Nepal. This paper intends to link between solid waste management and inadequacy in energy supply. Kathmandu Valley produces about 620 tons/day solid waste from its five municipalities. The study has shown some opportunities for Kathmandu Valley to convert its solid waste into energy. Even if only organic waste is treated, it produces energy sufficient to light more than 1000 houses in Kathmandu Valley. The quantity of waste, its heat content, the need of additional energy supply, the support from government and service users are some openings that hopefully can contribute to resolving the problems of solid waste and energy supply in Kathmandu Valley.
