Solid waste management (SWM) is one of the most critical global challenges nowadays. It has a severe negative effect on the triple bottom line of sustainability. Construction and demolition waste (CDW) contributes about 50% of the total global annual generated SW. In the particular case of the Middle East and North Africa (MENA) region including Egypt, the SW problem has become a major challenge, and the need to find sustainable solutions is overwhelming. However, the region faces several challenges that hinder the development of an effective and efficient SWM system. This has resulted in the predominance of unsustainable SWM practices such as indiscriminate disposals. The aim of this paper is to investigate the escalating problem of SW in the MENA region, while focusing on CDW in Egypt as a part of the total generated SW, by reviewing the most recent research papers, and technical and governmental reports on the SW problem. The main challenges towards effective and efficient SWM systems and recommendations for improvement are gathered in this study based on the explored literature. Findings from this study are expected to be beneficial to local and central governments, academics, construction industry practitioners, and policymakers contending with the problems of SW in the MENA region and especially CDW in Egypt.

埃及建筑业中固体废物问题的调查：小型审查。

固体废物管理（SWM）是当今最关键的全球挑战之一。它对可持续发展的三重底线具有严重的负面影响。建筑和拆除废物（CDW）占全球每年产生的SW的约50％。在包括埃及在内的中东和北非（MENA）地区的特殊情况下，西南软件问题已成为一个重大挑战，寻求可持续解决方案的需求已迫在眉睫。但是，该地区面临着许多挑战，阻碍了有效和高效SWM系统的开发。这导致了不可持续的SWM做法的普遍存在，例如不加选择的处置。本文的目的是调查中东和北非地区SW的升级问题，同时将埃及的CDW作为总SW的一部分，通过审查有关软件问题的最新研究论文以及技术和政府报告。本研究基于探索的文献，收集了有效有效的SWM系统面临的主要挑战和改进建议。这项研究的结果有望对地方和中央政府，学者，建筑业从业者以及在中东和北非地区，尤其是埃及的CDW问题上有争议的决策者有所帮助。
