The disposal of construction and demolition waste poses a growing challenge in Egypt, creating an urgent need for safer operational practices. Three primary factors govern safe disposal: managing collection and transport routes, identifying illegal dumping sites, and tracking and scheduling waste. An evaluation involving construction academics and industry practitioners assessed the applicability and effectiveness of these elements, as well as the role of automation techniques. The analysis established that choosing the shortest transport route is the most applicable measure, whereas detecting illegal disposal sites is the single most effective factor. Because positive statistical correlations link all evaluated factors to safe disposal, the development of an integrated conceptual framework represents the necessary next step for industry adoption.
Unregulated construction waste threatens local environments, public health, and municipal infrastructure during periods of rapid building activity. By clarifying which logistical and monitoring factors are most effective and practical to implement, these findings offer planners and industry leaders clear priorities for reducing illegal dumping and improving site management.
This work points towards potential applications in route-planning logistics and monitoring systems to detect unauthorised dumping for municipal bodies and waste management contractors. However, as the findings are based on survey assessments and conclude with the need to build a conceptual framework, the research remains at an early conceptual stage rather than close to market deployment.

Construction and demolition waste (CDW) is produced in conjunction with construction projects at various phases. In Egypt's situation, the disposal of CDW issue has grown to be a major problem, and there is an urgent need to discover a safe disposal method. Based on the exploration of the literature, three main factors that affect the safe disposal of CDW (SDCDW) were found as follows: (1) management of route, collection and transportation; (2) determination of illegal waste dumping sites; and (3) construction waste tracking and scheduling. In this paper, a wide sample of construction industry academics and practitioners were approached by an online survey questionnaire for (1) investigating the applicability and effectiveness of SDCDW factors in the Egyptian construction industry; and (2) examining the relationship between these factors and SDCDW. Different statistical methods were used such as Relative Importance Index (RII) to rank the framework items. In addition, Bi-variate correlation analysis was conducted to test the effectiveness of automation techniques included in the framework with respect to the level of agreement upon reaching safe disposal of CDW. The findings showed that (1) among the various factors, “selection of the shortest path transport route” has the highest applicability, while “detection of CDW illegal disposal sites” is the most effective factor; and (2) there exist positive statistical relationships between SDCDW and all of the various factors. The findings show that creating a conceptual framework for SDCDW in Egypt, which includes these various elements, is necessary as the next research initiative.
