The accumulation of material waste on construction sites often stems from underutilized procured materials, prompting a plethora of practical and scientific endeavors to mitigate waste and enhance construction project sustainability. This research study analyzes and synthesizes existing research on material waste management in construction projects from 2000 to 2023, aiming to investigate significant research themes and propose potential future research directions. Bibliometric and scientometric analyses are employed to examine the 205 documents retrieved from the Scopus database. The findings highlight that keywords like construction waste, waste management, and construction and demolition waste are the most prominent in the research domain. China and Malaysia are the leading contributors to this research subject. The Waste Management Journal is recognized as a seminal journal on construction material waste management. The qualitative evaluation reveals several prominent research themes: waste quantification and minimization, lifecycle assessment of waste, waste disposal and diversion practices, causal factors of waste generation and management, and circular economy and sustainable construction. The paper offers valuable insights for both scholars seeking new research avenues and practitioners interested in exploring prospective business opportunities.

Material Management Practices for Construction Waste Reduction

The Sustainable City XII

The construction sector plays a key role in shaping and developing the built environment creating wealth and development for the countries. At the same time the sector is producing negative impacts due to the vast quantities of natural resources required and the high amounts of waste produced. Costa Rica is a country in Central America that has a construction sector contributing in 2016 a 4.4% of its GDP. In the country, several studies have been done in order to determine waste quantities but not the composition of the construction residues. Additionally, causes of waste generation have been reported and grouped in the following categories: design, execution, material management, residuals and other activities. This paper presents the results of a research that has been done with the objective to determine the types of hazardous and non-hazardous waste that are produced during the procurement of an edifice as well as the best general practices used by innovative construction companies to reduce the amount of waste produced.

Resources Conservation and Waste Management Practices in Construction Industry

Oman Chapter of Arabian Journal of Business and Management Review, 2015

Changing people's wasteful behaviour can make a significant contribution for sustainable growth. This is because wastes are often hazardous in nature thereby making them potentially hazardous to human health and/or the environment. Sustainable livelihood within the environment where the presence of wastes has become a phenomenon makes efforts at addressing this menace a central issue. In the light of this, a strategic solid waste resource management planning approach has been identified as capable of enhancing plausible solutions to take care of its menace. Such planning has to take into cognizance a comprehensive strategy that can remain flexible in light of changing economic, social, material (products and packaging) and environmental conditions. In relation to the present study, the need for resource conservation in order to minimise the rate of waste generation is being emphasized. The necessity of this revolves around the environmental benefits inherent in such efforts and economic gains it will bestow on the construction industry and other stakeholders within the society. This paper investigates the management of wastes generated from construction and demolition activities that has wide-ranging impacts on the environment. Waste management is perceived as a low project priority, and there is an absence of appropriate resources and incentives support it. A theory of waste behaviour is proposed for the construction industry, and recommendations are made to help managers improve workers' attitudes towards waste.

Quantitative Analysis of the Sources of Construction Waste

Journal of Construction Engineering, 2014

The construction industry is traditionally environmentally unfriendly. The environmental impacts of construction waste include soil contamination, water contamination, and deterioration of landscape. Also, construction waste has a negative economic impact by contributing additional cost to construction due to the need to replace wasted materials. However, in order to mitigate waste, construction managers have to explore management options, which include reduction, recycling, and disposal of wastes. Reduction has the highest priority among the waste management options but efficient reduction cannot be achieved without adequate identification of the sources of waste. Therefore, the purpose of this paper is to present a study that was carried out on the contribution rates of nine identified sources of construction waste. Establishing the contribution rates of different waste sources will enhance knowledge-based decision-making in developing appropriate strategy for mitigating construct...

Sustainability assessment of Construction and Demolition Waste management applied to an Italian case

Waste Management , 2021

Construction and Demolition Waste represents a priority stream for the European Union and has a large potential for closing the material circulation loop in line with the Circular Economy principles. The present study focuses on the socio-economic and environmental implications of the management of such waste in the Campania Region (Italy), with the aim of documenting the benefits of recycling actions and landfill avoidance. By using local primary data, and complementing them with data from literature and datasets, three scenarios have been investigated: i) Status Quo, i.e., a baseline scenario presenting the current management of Construction and Demolition Waste in the Region; ii) a Linear Economy scenario, considering the total flow disposed of in landfill and iii) a Best Practice scenario based on the implementation of selective demolition practices and increased recycling for the production of high-quality recycled aggregates. Special attention has been paid to the land use and socio-economic implications linked to the management of this flow, which are rarely considered. We quantify that, with the implementation of best practices, ca. 18 Mkg CO2 -eq. can be saved annually relative to the Status Quo alongside creating additional 1,000 jobs-eq. and incurring important benefits on land use. The results stress that the potential environmental and social benefits of selective demolition and best practices are significant, but the incurred economic costs may hinder their application and the resulting development of more circular economy actions in the construction sector, highlighting the need for incentives and tools to facilitate this transition.

Impact of Construction Waste Minimization at Construction Site: Case Study

Jurnal Teknologi, 2016

Waste reduction in the construction sector is essential not just from the position of overall performance, but also interests escalated recently about the detrimental impact of the waste of construction materials on the natural surroundings. The reuse and recycling of construction elements used to be substantial due to material scarcity during the war and post-war era, specifically when the price of virgin materials keep inflating. Nevertheless, the motivation to reuse and recycle construction materials has fallen ever since the flow of raw materials has grown more consistent and satisfactorily. This paper involves an ongoing sequence of waste audits at Universiti Teknologi Petronas (UTP) R&D construction sites. The methodology consists of discussion, observation and quantitative evaluations of the kinds and distribution of wastes. The finding of this study demonstrates that the project aimed at both minimizing the volume of waste generated and diverting as much waste as possible fr...

Waste Management in a Sustainable Circular Economy as a Part of Design of Construction

Applied Sciences

The Architecture, Engineering, and Construction (AEC) industries are the producers of the most significant waste stream in the European Union. Known EU initiatives propose to deal with the issue of construction and demolition waste (CDW) according to the principles of a circular economy: the 3Rs (reduce, reuse, and recycle). CDW is generated during the whole life cycle of construction. The lack of information about the quantity of CDW during the design phase of building needed for sustainable design of construction was identified as a research gap. The aim of our research is to quantify construction and demolition waste during the construction design phase in a circular economy. The proposed method is based on the generation rate calculation method. This paper describes the proposed methodology for quantifying selected types of construction waste: excavated soil, concrete, and masonry. This information is essential from the point of view of a sustainable circular economy. The main c...
