The challenges of urban management in Uganda

The urban areas in Uganda are increasingly getting under pressure from a rapidly growing population. The challenge of a growing population has coincided with the central government policies that favour rural districts more than urban areas. The challenges that the urban areas face include the problem of two populations (the night and day time); high generation of garbage; poor revenue base; a growing informal sector; growing squatter settlements; deterioratingwater quality; and the limited institutional capacity to provide the required urban services. Financial resource mobilisation has been inadequate due to high costs oft= administration, low institutional capacity for enforcement, and a general public apathy to tax payment.

Determination of solid waste components in a selected university food service

Identifying the components of solid waste within a foodservice operation is the first step in linking the generation and management of garbage. The primary objective of this study was to determine the amount and type of waste generated at a selected university food service operation. The feasibility of recycling various waste components was also investigated. Solid waste components other than food were sorted and measured by weight and volume during the nine-week study. Solid waste at the university averaged 3,530 lbs per week by weight and 9,822 gallons by volume. Cardboard was not included in the volume measurements. Paper products were 71%, plastics 20%, tin 8%, and glass, aluminum and wood 1% of total solid waste by weight. Meals served at all sites on campus, including catered events, averaged 6,443 meals per week. The amount of solid waste generated during the study was remarkably constant. Statistical analysis showed no significant difference in waste weight related to either menu cycle week or customer count. An analysis of time and labor costs for recycling compared to local rates for recyclable materials suggested that it is currently economically feasible to recycle only white paper and cardboard from this operation.
