Science mapping approach to assisting the review of construction and demolition waste management research published between 2009 and 2018

Sustainable treatments of construction and demolition (C&D) wastes have become an increasingly urgent social, environmental, and economic issue worldwide. Based on a filter of 370 articles related to C&D waste management, this review-based study adopted a science mapping approach to evaluating the recent decade’s C&D waste management research. Through a three-step workflow consisting of bibliometric literature search, scientometric analysis, and qualitative discussion, this study identified the most influential journals, scholars, articles, and countries that have been active and influential in the C&D waste management research since 2009. Keyword analysis revealed the emerging research topics, such as BIM, prefabricated construction, Big Data, and Circular Economy. The follow-up discussion summarized the mainstream research areas (e.g., qualification of waste generation), discussed research gaps (e.g., integration of BIM and Big Data into C&D waste management), and proposed the framework for near-future research, such as a comprehensive evaluation of the performance of C&D waste diversion, human factors, and design and planning for waste diversion. By providing the big picture of the latest research in C&D waste management since 2009, the paper serves as a multi-disciplinary guide for practitioners and researchers to link current research areas into future trends

A Dynamic Model for Construction and Demolition (C&D) Waste Management in Spain: Driving Policies Based on Economic Incentives and Tax Penalties

According to the recent Spanish legislation, the amount of non-hazardous construction and demolition waste (C&D waste) by weight must be reduced by at least 70% by 2020. However, the current behavior of the stakeholders involved in the waste management process make this goal difficult to achieve. In order to boost changes in their strategies, we firstly describe an Environmental Management System (EMS) based on regulation measures and economic incentives which incorporate universities as a key new actor in order to create a 3Rs model (Reduce, Reuse and Recycle) in the C&D waste management with costs savings. The target areas are focused mainly on producer responsibility, promotion of low-waste building technologies and creation of green jobs to fulfill three main objectives: valorization of inert wastes, elimination of illegal landfills and stimulation of demand for recycled C&D wastes. To achieve this latter goal, we have also designed a simulation model—using the Systems Dynamic methodology—to assess the potential impact of two policies (incentives and tax penalties) in order to evaluate how the government can influence the behavior of the firms in the recycling system of C&D waste aggregates. This paper finds a broader understanding of the socioeconomic implications of waste management over time and the positive effects of these policies in the recycled aggregates market in order to achieve the goal of 30% C&D waste aggregates in 12 years or less

The Case for Sustainable Concrete Waste Management in Qatar

The construction industry is a major generator of waste. There are many challenges associated with implementing sustainable methods to manage construction waste. While the construction industry in the State of Qatar has been adopting plenty of progressive practices, waste management, especially of concrete waste, has not advanced notably. In addition to the limited supply of limestone suitable for use as natural aggregate for concrete production in Qatar, the ability to recycle and reuse concrete waste is critical to reducing environmental impacts to meet national, regional and global environmental goals. Therefore, this research aims to identify the current status of concrete waste management practices in construction projects in Qatar exemplified by a local case-study project. Concrete waste was particularly monitored over the span of the construction stage of a large research and development facility in Qatar, benchmarking trends and practices on a certified “green” building. In response, this study addresses key challenges to concrete waste recycling and reuse to then recommend opportunities of advancements in local concrete waste management and reuse

Exploring critical success factors for waste management in construction projects of China

The enormous amount of construction activity in China associated with its rapid economic development has produced a large amount of construction and demolition (C&D) waste over the past three decades. The majority of this waste has not been well processed, which has led to severe damage to the environment. Although there is clearly a need for better C&D waste management (WM) in China, the best ways to achieve this have yet to be fully explored. This paper is based on a study by the authors that aimed to identify the Critical Success Factors (CSFs) for C&D WM in China. A questionnaire survey and 14 semi-structured interviews with practitioners, researchers and government officials were conducted in Shenzhen, a leading city in southern China for tackling C&D WM. Seven factors were identified as the CSFs for managing C&D waste: (1) WM regulations, (2) waste management system (WMS), (3) awareness of C&D WM, (4) low-waste building technologies, (5) fewer design changes, (6) research and development in WM, and (7) vocational training in WM. These CSFs can serve as valuable references for stakeholders to develop effective C&D WM strategies. The research also adds to the knowledge on how to reduce adverse environmental impacts caused by construction activities in rapidly developing economies. © 2010 Elsevier B.V.

Construction and Demolition Waste Management Practices in Sarawak: Priority for Regulation, Human Resources and Construction Method

Waste management is implemented by destroying and eliminating all waste from any sources of activities such as construction and demolition, minimising the waste, and reusing or recycling it. The primary purpose of managing waste is to reduce the amount of waste generated, and the reduction of waste aims to protect the environment. Improper waste management can cause damage to the ecosystem, increase air and water pollution, and destroy our health. Because of Sarawak's population increase, waste generation is becoming a big challenge. Among the major significant issue is lack of awareness, incompetence of the person in charge, administrative issues, lack of enforcement and poor technology. This study investigates the current implementation of managing construction and demolition waste in Sarawak. A questionnaire set was designed to obtain a perceptive opinion on the waste management practices in construction projects and demolition in Sarawak. A questionnaire survey was designed and distributed to 50 respondents from construction players in Sarawak. The respondents are among the construction players, including architects, contractors and consultants. The finding shows that many construction companies know the importance of managing waste as they have a procedure for managing waste in their construction operation. Moreover, concrete and aggregates list the highest-ranking waste from construction and demolition activities. This study provides mitigation measures and strategies to minimise the problems. It is anticipated that the finding of this study could assist contractors and developers in having a proper waste management system
