Abstract:
Waste in urban areas is growing rapidly everywhere in the world. Effective methods to address the challenges of solid
waste management are critical in achieving a clean and healthy environment. The problem of waste growth in urban
areas has been brought about by low collection of waste, illegal and uncontrolled dumping sites and the absence of
sewage lines. In Kenya, for instance, the growth of the economy, which resulted in the development of cities and the
emergence of towns, led to waste management challenges. Efforts have been directed towards addressing the problem
of waste management by various county governments. This study sought to address solid waste disposal and
management challenges in Nyamira Municipality. The methods that are being employed to address this challenge are
costly and have not yielded desirable results, as was evident from the scattered waste in the streets of Nyamira
Municipality. Currently, the management does not carry out any waste recycling and has hired one landfill, which is
paid for monthly. This Study formulated a solid waste management tool that involved the construction of a fuzzy goal
programming model. The model was solved analytically using the simplex method. A sensitivity analysis was carried
out, and graphs were drawn using MATLAB software. The utility of the model was tested using data from Nyamira
municipality. The research advocated for waste recycling as one of the ways of managing waste to earn revenue from
this recycled waste. The findings of this study are useful in formulating policies such as setting up waste management
projects and establishing recycling industries. This will go a long way by reducing the cost by at least 36%.
Furthermore, the findings form the basis for future research in related fields
