The research deals with the main issues in estimating construction and demolition waste to benefit from the recovery of construction waste within the framework of sustainable construction and determining the requirements for evaluating construction waste and recycling rates in housing projects that depend on the definition of construction waste, the status of construction waste when it is subject to recovery and recycling, and The importance of studying the construction waste management project from the designer engineer, which includes estimating the amount of construction waste (tons per m2) and the methods used during the design phase. The composition of construction waste was studied through the three stages of the life cycle of buildings, and it was reached through the analytical comparison between the proportion of construction waste Resulting from residential buildings, a concrete structure at the global level, and the Egyptian level. It shows the different percentages of waste generated for some construction waste due to the different nature of construction and uses, and as a result of the different nature. International experiments were studied for estimation of building waste and several methods were deduced for calculating the amount of construction and demolition waste.
