Comprehensive feasibility study for the construction of an integrated sustainable waste management facility in Kajiado county, Kenya

Abstract

The work focuses on the feasibility study relating to the design of a new integrated sustainable waste management facility in Ngong town (Kenya), within the Kajiado County; the County borders Nairobi and extends to the Tanzanian border further south. Currently, the waste generated in Ngong town is sent to an illegal dumping site, which must be closed as soon as possible since it is causing serious environmental and social impacts. Specifically, the purpose of the study was to carefully analyze the context, taking into consideration environmental, economic and social aspects, providing technical–economic solutions which must be robust, easy to build, operate and maintain, be cost-effective and self-sustaining from an economic standpoint, and be environmentally and socially sustainable. This chapter focuses on the assessment carried out in view of designing a new integrated sustainable waste management facility. An estimation of the mass and energy balance and of the system design and sizing is also provided, together with an assessment of the overall economic sustainability of the proposed intervention.
