摘要

The success of any waste management system requires accurate and up-to-date data on quantity, composition of waste. Waste generation data from household are needed to address issues relating to municipal solid wastes such as management method, performance improvement, policy, regional and local planning, administrative, cost accounting, design and operation of landfill facilities and environmental quality. This study was conducted to provide empirical data on generation rates, quantity and composition, management practices, challenges and strategies from urban household. Waste collection, weighing, questionnaires survey and field observation were methods used during the study. Waste was collected and weighed from 60 households using multi-stage sampling technique for seven days. Questionnaires were analyzed using Statistical Package for Social Sciences version 20 and Excel. A total of 1125.2 kg of waste was recorded. The average household waste generation was 3 kg per day with per capita generation rate of 0.41 kg/cap/day. The compositional analysis showed that Organic (53%), Plastic (11%), Textile (6%), Metal (2%), Glass (1%), Paper and Cardboard 4% and others (22%). Solid waste management practices are very rudimentary. Burning (53.7%) and Open Dumping (30%) were found to be the most commonly used method of disposal with very limited collection service (33.3%) and segregation. The most challenges faced by households were communal disposal area (66.7%) and waste service providers (21.7%) storage bins (11.6%). Waste to energy (48.3%) and compositing (23.3%) were the most considered option for waste management by the respondents.
