Unlike developing countries, most developed countries address the problem of construction and demolition wastes (CDW) accumulation. In Egypt, CDW recycling plants are minimal. This study is devoted to understanding the economic aspects of constructing and operating a construction and demolition concrete waste recycling plant in Egypt. This includes accounting for several factors such as location, design of the recycling plant, the equipment used, and the material entering and leaving the plant. This is followed by implementing a detailed economic viability analysis that assesses the savings resulted from recycling concrete waste to produce recycled aggregate. CDW recycling plants give rise to economic viability as they seem economically viable even in the absence of specific government policies. A comprehensive case study of an actual project in New Cairo City in Egypt is presented in order to demonstrate the process of CDW disposal and illustrate the practical features of the proposed model.
与发展中国家不同,大多数发达国家已经解决了建筑和拆除废物(CDW)堆积的问题。在埃及,CDW 回收工厂很少。本研究致力于了解在埃及建造和运营建筑和拆除混凝土废物回收工厂的经济方面。这包括考虑几个因素,如位置、回收工厂的设计、使用的设备以及进出工厂的材料。接下来是实施详细的经济可行性分析,评估回收混凝土废物生产再生骨料所带来的节省。CDW 回收工厂具有经济可行性,因为即使没有特定的政府政策,它们在经济上似乎也是可行的。本文通过埃及新开罗市的一个实际项目的综合案例研究,展示了 CDW 的处理过程,并说明了所提出模型的实际特点。
