| dc.description.abstract | Construction solid waste has impacted negatively on the environment. Reuse, recycling and reduction of construction materials have been advocated for many years, and various methods have been investigated. The rates of reusable and recyclable waste for important construction materials such as plastic, paper, timber, metal, glass, concrete, masonry, plaster, and tile are examined in this research. The ratios of actual reusable and recyclable material over total construction waste define the rates of reusable and recyclable waste. Five case studies, projects (P1-P5) are conducted in the sub city for the investigation. The highest rate of reusable and recyclable waste is found in "metal," while the lowest rate is found in "plastic." The key hurdles to reuse and recycling of construction materials in the local construction sector are identified as a result of this investigation. Over the last two decades, the quantity of construction waste created has increased in lockstep with the expansion in building activity. This expansion, along with a scarcity of landfill space, particularly in urban areas, has proven to be a difficult environmental source of stress. Management of construction waste has thus become a problem attracting increasing attention worldwide. The quantification of waste streams created at various phases of construction is the first step in controlling construction waste in this context. A methodology for assessing waste streams arising at various construction phases is also proposed in this study. The approach is then put to the test in the field to estimate generation rates for main waste streams as well as the total construction waste generation rate in order to produce a generalized construction waste management plan that can be implemented at the local, regional, and national levels. The study's findings show that the total construction waste generation rate is between 32.76 and 33.7 kg/m2, with masonry and concrete constituting for more than 59.9% of the total waste. The study concludes with a set of recommendations and suggestion addressing the most important issues contributing to a successful implementation of an integrated construction waste management plan. Construction Waste Management is an aspect of Sustainable Development, which is fueled by the growing concern for the effect of man’s activities on the environment. This research final studied the practice of Construction Material Waste Management as one of the specific objective by firms in Addis Ababa, N.S.L sub xiv city by the use of structured questionnaires to senior construction professional personnel of construction firms. Most respondents displayed a poor understanding of waste management and most companies did not have a policy on Material Waste Management. The paper recommends that the Ethiopia Government puts in place legislation regarding construction site waste management. Professional bodies and academic institutions in the country should seek to further educate their members on the importance of effective material waste management strategies. | en_US |
