The issue of sustainability has long been the subject interest in architecture engineering and construction sector. All three aspects sustainability—economic, environmental, social—can be affected through appropriate waste management. Construction demolition (CDW) is one largest worldwide streams, therefore, it given great attention by all stakeholders (investors, contractors, authorities, etc....

Discrete-Event Simulation is an event-driven simulation in which a real dynamic process is imitated as it progresses over time. It has been recognized as a powerful technique for the quantitative analysis of complex construction operations. The two main DES strategies for modelling construction operations are Process Interaction (PI) and Activity Scanning (AS). Although each strategy has its ow...

A significant problem that has emerged in the field of construction and demolition waste management (C&D), involves the integrated optimization of the entire C&D waste supply chain. The critical decisions to be made include among others: (i) the determination of the optimal deconstruction depth for each EOL construction site before the demolition process, and (ii) the design of an effective tra...

In this paper, a location allocation (LA) problem in construction and demolition (C&D) waste management (WM) is studied. A bi-level model for this problem under a fuzzy random environment is presented where the upper level is the governments who sets up the processing centers, and the lower level are the administrators of different construction projects who control C&D waste and the after treat...

The utilization of many industrial byproducts in the construction industry is now well-developed as it helps in improving the sustainability in two ways. First, reuse of the materials which otherwise will burden the environment and will be occupying scarce land resource. Second, it minimizes the degradation of land and the environment as a result of comparatively less digging. Quantities of was...

Tehran, the capital city of Iran and a metropolis with a population of 8.2 million and containing 2.4 million households, generated 2,626,519 tons of solid waste in 2005. The present study is aimed at evaluating the generation, characteristics and management of solid waste in Tehran. Municipal solid waste comprises more than 97% of Tehran's solid waste, while three other types of solid waste co...

Polymer-cement composites (PCCs) are materials in which the polymer and mineral binder create an interpenetrating network and co-operate, significantly improving the performance of the material. On the other hand, the need for the utilization of waste materials is a demand of sustainable construction. Various mineral powders, such as fly ash or blast-furnace slag, are successfully used for the ...

The current study presents an investigation on the waste management in the cattle slaughterhouse by the following objectives: a) to identify the existing waste management practices in relation to sources, quantity and characteristic of wastes; b) to identify the situation of production, collection, storage, transportation, processing and recycling, and final disposal of wastes and the problems ...

Construction of flexible pavements with hot mix asphalt (HMA) mixtures consumes huge energy which impacts the resources and the environment of the world. Warm Mix Asphalt (WMA) is an effective alternative as they produced with lower mixing and compaction temperature than those used in HMA production. This technology decreases energy consumption, saves money, and reducing the environmental pollu...
