In comparison with other construction sectors, infrastructure projects are recognized for their relatively longer operation periods, important societal, economic benefits, and extensive consumption of natural resources. The rapid global economic development in the infrastructure industry and rising levels of environmental concerns lead to an increa...

This research proposes a framework for sustainability assessment for power plant projects. The proposed framework integrates sustainability and Building Information Modeling (BIM) to achieve enhanced results concerning sustainability assessment in the power plants sector. International and regional sustainability rating systems as well as design gu...

Environmental pollution is considered to be one of the main concerns in the construction industry. Environmental pollution has become a major challenge to construction projects due to the huge amount of pollution caused by construction projects. There are different types of environmental impact indicators, such as the greenhouse gas (GHG) footprint...

The removal of lead, copper, and cadmium from aqueous solution using cement kiln dust (CKD) has been investigated under batch equilibrium technique setup. The adsorption behavior of the target metals is examined as a function of pH, contact time, sorbent dose and initial metal concentration. The metal hydroxide precipitation is studied to determine...

Wastewater treatment technology has been improved in developing odor control. The odor control strategies aim to minimize odor nuisance beyond the treatment plant facilities’ boundaries. This paper presents the adopted odor control strategy at an advanced WWTP in Egypt that shares boundaries with residents. A comprehensive evaluation of the odors f...

One of the main concerns of implementing Anaerobic Digesters (AD) that result in releasing biogas is the disposal of large quantities of organic wastes in an economically and sustainable manners. This paper evaluates the economic sustainability of implementing anaerobic digesters and capturing the released biogas for energy utilization in contained...

Cement Kiln Dust (CKD) as a low cost adsorbent for heavy metal cations uptake was examined. Adsorption studies in completely mixed batch reactors were used to generate equilibrium pH adsorption edges. Studies showed the ability of CKD to remove the target heavy metals in a pH range below that of precipitation after an equilibrium reaction time of 2...

Ion exchange, reverse osmosis, and chemical precipitation have been investigated extensively for heavy metal uptake. However, they are deemed too expensive to meet stringent effluent characteristics. In this study, cement kiln dust (CKD) was examined for the removal of target heavy metals. Adsorption studies in completely mixed batch reactors were...

Activated carbon produced from cotton stalks was examined for the removal of heavy metal contaminants. Adsorption studies in completely mixed batch reactors were used to generate equilibrium pH adsorption edges. Continuous flow experiments using the activated carbon in fixed beds were conducted to determine heavy metal breakthrough versus bed volum...

Utilization of agricultural waste to produce valuable products has opened opportunities in Egypt to minimize serious public health risks from exposure to dangerous fumes that come from burning the agricultural wastes in open fields. In this study, activated carbon produced locally from cotton stalks was examined for the removal of target heavy meta...
