case study on construction waste management

In the case of building demolition, the construction industry increasingly prioritizes sustainable waste management and environmental protection. Life cycle assessment (LCA) was used to assess two scenarios to evaluate the environmental impacts of four methods (demolition, transport, recycling, and landfills). To conduct an Attributional LCA, the SimaPro software suite and Ecoinvent v.3 Life ...

The Gulf Cooperation Countries (GCC) consistently rank among the top 10% of per capita waste producers in the world. Collectively around 120 million tons of waste is produced annually in GCC; 55% construction and demolition (C&D) waste, 20% municipal solid waste (MSW), 18% industrial waste, and 7% hazardous waste. Like other GCC nations, the Kingdom of Saudi Arabia (KSA) generates massive ...

According to Chile's Environment Ministry (2010), 5 million tonnes of construction waste are generated annually. According to the Chilean Chamber of Construction, building permits in. 2011 increased by 55% in comparison to 2010, in a year which saw the highest number since 1992 (Report Mach-35, April 2012).

The study concluded that considering construction waste increases national income, encourages companies to decrease waste, and keeps the environment clean. The study recommends the establishment of new building waste departments in municipalities and ministries, waste management rules, and efficient approaches to reduce construction waste.

anagement at construction site is the main cause of construction waste generation. This is due t. the lack of disposal facilities and the remaining residual rules (Njoroge, 2012). This factor was also highlighted by Hassan, Ahzahar, Fauzi and Eman (2012) as they claimed that inappropriate construction of building.

1 Introduction. The United Nations Environment Programme (Wilson et al., 2015) global waste management outlook warns that the growing volume and complexity of garbage produced by the modern economy puts ecosystems and human health at risk.An estimated 11.2 billion tonnes of solid trash are collected annually worldwide, and around 5% of the global greenhouse gas emissions are caused by organic ...

The Recommended Practices are designed to be used in a wide variety of small and medium-sized business settings. The Recommended Practices present a step-by-step approach to implementing a safety and health program, built around seven core elements that make up a successful program.

Today, for balanced environmental management, it is necessary to consider and assess the availability and condition of natural resources and the environment quality on time. To accomplish the goals specified, this paper suggests using the databases characterizing the...

Forecasting the development of regions is one of the most challenging tasks of modern economics. The quality of any forecast is determined by the methodology used. Accordingly, criticism of existing forecasts is largely connected to their methodological approaches. In this paper, a multi-level approach to forecasting the development of the region is proposed, starting with the definition of ...

The case study's C&DW management was impacted by two major building construction standards, LEED and GSAS (Ferwati et al., Citation 2019; Ismaeel, Citation 2020; Saleh & Al-Swidi, Citation 2019). At the time of the study, waste management methods were in the hands of the project's contractors.

Currently, many types of research studies in the field of construction and waste management are adopting case studies as part of the methodology [11]. Many authors [27], [10] highlighted that case study research could be used for exploratory, descriptive a well as critical studies. This study adopted a combination of a descriptive and ...

However, Lorca (2015) stated that effective waste management must be initiated in two phases: pre-disaster and post-disaster. In the pre-disaster phase, protective disaster waste-management strategies should be introduced, by offering an imperative solution to reduce the risks posed by hazards and to attain speedy recovery after disaster.

Zezhou Wu, Zezhou Wu. ... the aim of this study is proposing solutions for further improvement of effective C&D waste management in Hong Kong. Based on a comprehensive content analysis of seven selected countries and two ...

Environmental and economic water resource maps were constructed using the Surfer software, which is the most relevant for this test according to the reviewed publications [1-4]. In practice, maps can be created using various methods [5, 6]. In our research, we used the Kriging method to develop the environmental and economic water resource maps.

Construction waste recycling (CWR) is an effective strategy to avoid CW disposal in landfills (Ulubeyli et al., 2017).Also, CWR is a waste management strategy that is preferable and environmentally more advisable than disposing at landfills (Brum et al., 2021).Furthermore, CWR converts CW into new materials for use (Bao and Lu, 2021).Therefore, CWR is considered indispensable in construction ...

The total concrete waste estimated for Case Study A is 312.2 m 3 (725.2 tons - using the concrete density of 2322.7 kg/m 3; ACI Committee 318, 2014), and for Case Study B is 385.5 m 3 (895.4 tons). These estimates were validated with actual waste generation cataloged in the waste hauling tickets of the case studies.

The huge generated amounts of construction and demolition (C&D) waste around the world, which amounts up to more than 25% of the total generated waste, has become a serious environmental challenge that needs to be addressed. This analytical review paper sheds light on the different adverse environmental impacts of the presently used conventional management method of landfilling and proposes ...
