![]() It was found out that all the seven solid waste management practices identified and tested, only two waste generation practices, and transfer and transport practices were moderately done well. Quantitative data analysis technique (such as mean, percentages, frequencies and standard deviation) and qualitative data analysis technique (such as content analysis) were used to analyse the collected data. Questionnaire was the main data collection instrument used for the study. A sample size of 200 was used out of a total population of the study was 350. The purposes of this thesis were to identify the solid waste management practices in KMA. It spans all stages of human activities, from manufacturing to consumption. Waste products arise from our ways of life and it is generated at every stage of the process of production and development. Keywords: Kigali, Master plan implementation, construction, demolition, C&D waste disposal Building companies, waste collectors and the team in charge of Nduba landfill have to collaborate for effective management of construction and demolition waste in Kigali. Building companies have to establish facilities for recycling their waste in order to reduce the waste to be taken to the landfill. The city authority has to involve local authority in the supervision for awareness and avoiding the construction of building out master plan. The lack of willingness of building companies to separated the waste is a challenge for both drivers of waste collectors companies and technicians at Nduba landfill, the culture of reserving waste for later reuse or sell out for recycling is the main cause for illegal disposal of construction and demolition waste in city of Kigali and this need to be addressed. There is a poor accessibility of road toward Nduba landfill, due to high traffic, high slope and improper condition on top layer of road. Implementation of Kigali city master plan involves several construction of new buildings, demolition of some old buildings and the supervision of city authority in charge of master plan, through which buildings execution process is checked out and in sometime it involves the demolition of some buildings out of master plan layout and this results in generation of construction and demolition waste. The main findings and analysis of research are discussed as per variable in each sub question. The respondents were project managers and site engineers from building companies that conduct both construction and demolition activities, the assistant deputy from the department of urban planning and construction one stop centre, which is in charge of city master plan, drivers and coordinators of approved waste collectors companies in Kigali, the coordinator and technician in charge of Nduba landfill. This is an explanatory study I used qualitative research instruments such as semi-structured interviews and observation. Zero waste concept, urban regime theory and theory of planned behaviours all were selected to support the main concept. In order to answer this question, I have divided it into the following sub-questions: How does implementation of Kigali city master plan affect construction and demolition waste in Kigali? What is the situation of construction and demolition waste disposal in Kigali? How does the willingness of building companies to collaborate in waste separation affect the disposal of construction and demolition waste in Kigali? How does the accessibility of the road to Nduba landfill affect the disposal of waste in Kigali? Integrated solid waste management concept was used in this study as an umbrella for other theories and concept. The main research question of the study is: To what extent do an implementation of Kigali city master plan, road accessibility to Nduba landfill and willingness of building companies to collaborate in waste separation influence the disposal of construction and demolition waste in Kigali. The objective of this thesis is to explain how the implementation of Kigali city master plan, road accessibility to Nduba landfill and the willingness of building companies to collaborate in waste separation are influencing the disposal of construction and demolition waste in Kigali. The thesis considers the implementation of Kigali city master plan as the main source of C&D waste and Nduba landfill as the approved dumping area for all wastes generated in the city of Kigali. This thesis focuses on the factors affecting illegal disposal of construction and demolition waste in Kigali.
