The document outlines a plan for an integrated waste management system for Banepa Municipality, Nepal, focusing on biogas generation and incineration. It analyzes the municipality's current waste generation and composition. Projections estimate the municipal solid waste will reach over 10,000 kg per day by 2022. The plan designs a biogas digester to process the city's biodegradable waste of over 4,500 kg per day and an incinerator to reduce the volume of over 2,700 kg per day of combustible non-biodegradable waste. The proposed system has the potential to utilize biogas for electricity generation and decrease waste volumes sent to landfills, providing a more sustainable waste management solution for

 Poor waste management of Banepa
Municipality
 Practice of open dumping
 Over burdening of dumping site
 Absence of sanitary landfill
 Proposed landfill site is18 KM far from BM
which will increase waste management
cost
 Need of effective waste management
system

up to 10% thus increasing the life of
dumping site
 ISWM using biogas and incinerator can be
efficient method for waste management in
BM

28. Recommendation
 Installation of air pollution control
equipments if needed
 Installation of pressure gauge and its
continuous check

biogas and incinerator
 GIS mapping of transportation and
collection routing

29. Further Research
Biogas
