Construction Waste Management in Uae: An Exploratory Study
2019
In 2016, 9.68 million tons of solid waste were generated in Abu Dhabi alone where 67.8% was sent to dumpsites and landfills. In the same year, the construction and demolishing (C&D) industry produced 47% of the non-hazardous waste. This research aims to investigate the C&D waste management in UAE’s construction industry, specifically in Abu Dhabi based on (a) official resources identifying authorized entities, regulations, implementation guidelines, and causes behind waste generation in UAE’ C&D industry; and (b) unstructured interviews with construction professionals in Abu Dhabi revealing the waste management consideration process, enhancement methods, professionals’ responsibilities and views toward the topic. While Abu Dhabi’s sustainability framework (Estidama) requires a submittal of C&D Waste Management Plan (CDWMP) prior to any construction activity asking for a minimum of 30% waste diversion from landfills, relevant literature highlighted awareness as an effective factor in...
The Implications of Construction and Demolition Waste Management in Jordan
Environment and Ecology Research, 2023
Jordan's economy is one of the most robust and rapidly expanding in the Middle East. Construction and demolition (C&D) waste generation in the nation has dramatically increased due to the country's fast industrialization. Therefore, there is a raging concern over waste management infrastructure, particularly when most C&D waste in Jordan is disposed of informally. Hence, the research has reviewed previous literatures to identify the gaps in the body of knowledge about C&D waste management which helped in determining the method of quantitative questionnaires with practitioners and governmental bodies involved in C&D waste management in Jordan to be used. The literature analysis showed the construction sector and its components, legal frameworks, environmental, social, and economic ramifications, as well as the primary C&D waste management strategies and reveals that current strategies for managing C&D waste in Jordan are insufficiently developed. Thus, the purpose of the research in response to the findings of the literature was to ascertain what is lacking in the Jordanian context in terms of C&D waste management including informal dumping, aspects within Jordanian construction industry contracts, missing C&D waste management activities, encouragements to improve C&D waste management strategy, and the industry actors’ perspectives. The main findings demonstrate that the construction sector has a significant impact on Jordan’s environment by nearly informally dumping 50% of the total volume of C&D waste generated. The findings have identified that most problems relating to C&D waste are associated with governmental controls and industry actors (construction and demolition contractors). Including a general lack of legislative control and its enforcement accompanied with poor oversight and contractors’ perspective and willingness. In addition, appropriate procurement methods are not adopted, particularly for demolition projects. Results have shown that the absence of design codes of practice for recycled waste materials and poor waste disposal systems are strongly influential factors too. The findings identify the measures necessary to push the Jordanian construction industry toward improved C&D waste management by developing a set of encouragements. The key aspects of these encouragements include modifying the current regulations, the imposition of penalties or fines on polluters, enriching the local market with recycled waste material market, increasing the fees of disposal, and providing tax exemptions. The research not only develops enhancements to Jordan's C&D waste management strategy, but also provides a future benchmark for a successful national C&D waste management plan.
A Case Study of Sustainable Construction Waste Management in Saudi Arabia.pdf
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 amounts of MSW, C&D waste, and industrial waste. This study aims to examine 81 construction companies in the Eastern Province of KSA to determine which factors critically affect the sustainable management of C&D waste in the country. Only 39.5% of the companies studied had a pollution control plan for their projects. It was also found that only 13.6% of C&D waste is recycled and reused every year, whereas the remaining 86.4% C&D waste eventually goes to the landfills. Most of the C&D waste in the country is a promising source of potential recyclable construction materials such as gravel from debris, metals, and sand. This would not only fulfill the requirements of gravel and metal production of the KSA but also solve the waste disposal issues along with generating huge economic benefits. However, to accomplish the goal of sustainable construction waste management, it is critical to underline the various factors that might impact the construction waste management practices in the country.

The Need for a Proper Waste Management Plan for the Construction Industry: A Case Study in Lebanon
Sustainability
The construction industry is known as one of the biggest generators of solid waste. Considering this, attention needs to be paid to construction and demolition (C&D) waste. Lebanon has experienced many situations that have increased the generation of C&D waste. Therefore, it is essential to manage C&D waste. This research aims to assess and analyse the importance of waste management plans and their impact on the generation of construction and demolition waste in Lebanon. For this purpose, an extensive literature review has been carried out, and a questionnaire survey consisting of five sections has been developed. Factors were ranked by using 5-point Likert scales. Additionally, four optional open-ended questions were also included in the survey for qualitative data collection. A survey questionnaire was sent to 80 Lebanese experts, and 50 questionnaires were returned. Most of the responses (i.e., consultants and academics) were from the private sector; results showed that responden...

Evaluation of Construction and Demolition Waste Management in Kuwait
Recycling
This research aimed to evaluate Kuwait’s current construction and demolition waste (C&D waste) situation by focusing on C&D waste generation and management issues. This work also investigated the causes and factors affecting C&D waste to understand the actual waste management activities and proposed strategies to minimize the waste generated at the local level. This study estimated C&D waste generation rates based on data collected from five construction projects and two demolition projects in Kuwait. In addition, a questionnaire survey was conducted to evaluate the causes of C&D waste generation. The results showed that the average C&D waste quantities generated by construction activities were 49.5 kg/m2 for public/commercial building projects and 35 kg/m2 for residential projects. At the same time, public/commercial construction, residential construction, and demolition works generated 1.480 ton/m2, 0.0495 ton/m2, and 0.035 ton/m2, respectively. The average composition of C&D wast...
Barriers to construction and demolition waste management in developing countries: Case of Iran
In light of the lack of interest in implementing waste management in developing countries such as Iran; exploring the barriers to waste management implementation becomes relevant as the driving force behind conducting the present study. Major barriers identified in previous studies, were selected through a review of literature. Afterwards, a questionnaire survey was administered among different categories of Iranian construction contractors and 101 duly completed questionnaires were received. Ranking of 15 barriers through statistical analysis revealed the absence of a systematic regulatory regime for Construction and Demolition (C&D) waste management for construction projects. Among other findings, a lack of attention to waste management in regulations; lack of necessary skills and knowledge among construction practitioners; lack of economically viable methods for managing waste; and lack of attention to waste management within the dominant culture of the community were identified ...

Construction and Demolition (C&D) waste is one of the most voluminous and harmful categories of solid waste worldwide, comprising 40% of the total volume of global waste. Waste minimisation is essential for sustainable waste management for environmental, social and economic benefits. Libya has particularly egregious C&D waste due to prolific and unregulated construction activities and conflict, and defective C&D waste management. This study presents a framework for sustainable construction and demolition waste management (SC&DWM) in the Libyan context. A critical analysis of different barriers affecting SC&DWM and strategies to overcome them are presented based on a combination of literature review and mixed methods research. During the first phase, questionnaires were distributed face-to-face to four different groups: the general public, two groups of experts and policy maker. The second phase involved a focus group discussion (FGD) to produce additional beneficial supporting data, particularly from experts, in order to strengthen the outcomes of the study. Data analysis revealed that the main barrier to SC&DWM in Libya is the lack of C&D waste management facilities, while the least important barrier was producing unrecyclable materials from construction activities. The key strategy for SC&DWM is increasing awareness of negative impacts of C&D waste and the positive influence of sustainable practices for organizational and national economics. The developed framework presents a coherent and systematic approach and identified strategies that could be used to address these barriers and lead to SC&DWM, including options available for SC&DWM, capacity building, implementation and enforcement and evaluation and reviewing. The practical implication of the findings is that Libyan central government, municipalities and organizations need clear vision, approaches and practices to achieve SC&DWM. To validate this research findings, internal and external sources were adopted. In addition, respondent validation technique was used to evaluate the framework. Respondents believed that this framework tailored to the Libyan circumstances and the framework is appropriate enough to obtain SC&DWM practices in the case study. The study also provides a range of targeted recommendations for SC&DWM in Libya to improve efficiency. Further work is necessary to implement construction waste management and waste management at the industrial level, as well as identifying the actual quantity C&D waste so far, and its composition and distribution in Libya.

Integrated Framework Towards Construction Waste Reduction: The Case of Egypt
International Journal of Civil Engineering
The construction industry is plagued with significant construction and demolition waste (C&DW) generated during various phases of construction projects. This waste has created a universal, pervasive, and enduring problem globally. To propose practical solutions to resolve this consequential issue, this research adopted a quantitative approach in two stages. The first stage involved an online survey, administrated to 360 methodically selected construction organisations working in Egypt, to evaluate the impact of six main factors on C&DW reduction (C&DWR). The six main factors are as follows: (1) materials procurement measures (MPMR); (2) materials procurement models (MPMO); (3) green building practices (GBPR); (4) legislation (LG); (5) culture and behaviour (CB); and (6) awareness (AW). The second stage comprised multivariate statistical analysis via the structural equation modelling (SEM) approach to develop an integrated framework for C&DWR, to support Egypt’s vision 2030. The resu...

Back ground :A huge quantity of industrial wastes is generates daily that exacerbates illegal dumping crisis due to the insufficient land and increasing cost associated with landfill disposal. Among different industrial activities, construction industry is not an environmentally friendly activity. Many studies conducted to encourage waste management activities and provide measures in construction activities. However, waste management and waste minimization among many of construction industries have not been successful and are not meet the requirement of the standard principals for sustainable construction waste management. For handling the waste arising among construction industry faces many challenges and it’s necessary to be applied more seriously. Objective: This paper aims to explore the willingness level of waste management practice and to assess the level of effectiveness factors for Iraqi construction industry. The exploring level of willingness to Client, Designer, Contracto...
