Towards sustainable construction waste management: Study on a disassemblable brick partition wall for the architecture, construction, and engineering industry

This study proposes an approach to combat construction waste in the architecture, construction, and engineering (ACE) industry by developing a disassemblable brick partition wall. Brick reuse is severely restricted by the presence of mortar; innovative approaches need to be explored. An existing strategy, utilizing mortarless interlocking, relies on non-standardized bricks. It is worth noting that these methods are not specifically created for disassembly, despite the fact that they theoretically could be. A relatively innovative technique for tightening and stabilizing brick units emerged in recent years, involving the utilization of metal components. Despite its potential, there are limited case studies of this approach. By drawing on two typical examples of pros and cons, MIFA 1862 and the UMAR Unit, we propose a new strategy and examine it from multiple perspectives. The findings of the analysis demonstrate how adaptable and versatile the proposed system is, allowing it to be modified into a variety of sizes and forms. Additionally, the system has proven to have considerable advantages in terms of construction speed, and energy efficiency throughout the structure's service time and in future use phases.

Elucidation of the Influence of Construction Waste Causative Factors and Strategies towards Sustainable Construction Waste Management Improvement

The uncontrolled generation of construction waste happened due to the rapid development of the construction industry become one of the significant environmental issues in Malaysia. Therefore, sustainability was applied in construction waste management strategies. Sustainability in construction waste management emphasized the relevance of co-development in the economy, environment, and society and helped to achieve harmony in the economy, environment, and society. Therefore, this research was conducted with the aims to identify the causative factors of construction waste, determine the construction waste management strategies, and discover the relationship between the causative factors of construction waste and construction waste management strategies towards sustainable construction waste management improvement. In this regard, this research was conducted quantitatively using the questionnaire as a research medium to obtain feedback from the construction organizations on the causative factors and management strategies of construction waste towards sustainable construction waste management improvement. The developed questionnaire was distributed via a virtual method among project managers as representatives of construction organizations operating in Penang. As a result, 29.6 percent of the response rate was accepted. The analysis showed that the management factor, regulation factor and prevention strategy was important factors and strategies for sustainable construction waste management improvement and found that there was a strong relationship between them. Finally, this research outlined strategies to achieve sustainable construction waste management improvement in the construction industry and create a better environment.

Digitizing the Construction Waste Management Process – Studying the Attitudes of the Participants in the Sector

Although the concept of “sustainability” has been known since the last century, it has acquired an increasingly key role and importance in almost all sectors of modern economy and development in the last decade, becoming a “good practice” for both the private and public sectors. Examples of sustainable practices and solutions in construction are also gaining speed and influence, although for the time being, sustainable construction has entered as a strategy more deeply in the USA and the countries of Western Europe than in our country. This includes the sustainable management of construction waste, i.e. planned and sustainable disposal, recycling and input of construction waste in future projects. The main goal of the article is to reveal the opinion and attitudes of the main participants in the construction waste management process in support of the hypothesis that there is a need to digitize this process in our country.

The Mediating Role of Policy-Related Factors in the Relationship between Practice of Waste Generation and Sustainable Construction Waste Minimisation: PLS-SEM

As the construction industry grows, it produces large volumes of construction waste, which has a tremendous environmental impact and generates public concern in the neighbouring towns. The construction industry generates a significant volume of waste and faces a challenge with poor construction waste minimisation in order to prevent adverse environmental and dumping impacts worldwide. In developing countries, regional waste management systems have increased problems. Environmental pollution (air, water, and soil) and human health issues are caused by waste produced in a country as a result of different cultural, social, and religious activities. Prior studies were reviewed to choose dimensions and items for the data gathering instrument. A pilot test was conducted to identify potential questionnaire adjustments, and hypotheses were tested using structural equation modelling (SEM). A total of 220 Malaysian construction professionals answered the survey, which yielded the results. Five hypotheses have direct correlations based on the findings, three of which have a significant effect. Furthermore, the findings reveal that policy-related factors mediate the relationship between improving factors and sustainable construction waste minimisation. In contrast, they did not mediate the relationship between current practices/generation and sustainable construction waste management. The established framework can help improve construction waste management and help achieve global sustainable development goals. The data reveal that adopting preventive plans to reduce construction waste is one of the most important aspects of enhancing profitability. This study could aid construction industry players in evaluating waste management components during the construction and design stages of a building project.

GERAÇÃO DE RESÍDUOS NA CONSTRUÇÃO CIVIL

The problems arising from construction and demolition waste have always been in our country. The civil construction industry is the sector that generates the most waste that impacts society and is the one that consumes the most raw materials. As a result, it is necessary and extremely important that there is a sustainable management of construction waste. The irregular dispositions of these residues cause many negative impacts to the environment, since they are often thrown in vacant lots, permanent preservation areas, roads and public places, harming the quality of life of the population. Recycling can generate a significant economic advantage in relation to the final destination both in regular deposits and mainly in relation to the irregular ones that cause so much damage to the environment. This study sought to collect information on the current situation on construction waste. And in order to be developed, the present work used bibliographic research in books, specialized magazines, periodicals, and electronic media. Concluding in the final considerations, in which vital points of the research are presented followed by the stimulations the continuity of the studies and the reflections on the generation of solid residues in the civil construction.

A novel approach for recycling engineering sediment waste as sustainable supplementary cementitious materials

Engineering sediment waste increases enormously with the massive utilization of underground space, which accounts for nearly 60% of the total construction and demolition waste in China. Currently, most of engineering sediment waste is transported to landfills for disposal, occupying large land resources and posing safety concern due to its excessive accumulation. Therefore, a novel and green recycling approach is urgent. Here, the engineering sediment waste was recycled with mechanical treatment and calcination, and used as supplementary cementitious material to partially substitute cement to prepare mortar for construction application. The mechanical properties of the prepared mortar were investigated, and the mechanism behind the proposed recycling approach was revealed through microscale characterizations. Results show that recycled engineering sediment can promote the secondary hydration in mortar, improving the compressive strength. The environmental impact of the proposed recycling approach and current landfilling method was compared through life cycle assessment (LCA). The proposed recycling method can save 1204.1 MJ/t of energy consumption, and 326.1 kg CO2eq/t of global warming potential compared to those of landfilling method. Furthermore, the multi-criteria analysis was adopted to evaluate the overall mechanical, environmental, and economic performance of mortar with recycled engineering sediment. The mortar containing recycled engineering sediment exhibits the best overall performance including mechanical properties, environmental and economic benefits among mortar prepared with various supplementary cementitious materials. Such findings provide an effective recycling scheme of engineering sediment waste on a vast scale and contribute to a sustainable construction waste management strategy.

Construction and demolition waste is defined as the solid waste generated from the construction sector, including construction work, finishes, renovations, restoration and demolition

Construction Waste as a Resource in a Sustainable Built Environment

The built environment requires ever-increasing amounts of raw material resources and at the same time bears the responsibility for the resulting waste. Waste is generated throughout the life cycle. In the initial phases it is referred to as industrial waste, while during construction, reconstruction, and demolition it is called construction waste. Construction waste is most voluminous but it also has a great potential in circular economy that aims at the closed loop cycle where already used construction materials and components are recovered as raw materials. Sustainable building principles include four basic strategies, waste avoidance, construction materials and components re-use, continued use, and recycling. The possibility of construction waste treatment and its possible recovery in the building process depends on the type of prevailing materials that are contained in building elements as well as on detachability, separability and inseparability of structural joints and components. The architect plays a responsible role in decreasing the volume of construction waste as the conception of a building represents the key factor in sustainable construction waste management. Planning a construction with a good dismantling potential at the end of the building’s life cycle includes a number of factors such as the choice of building materials with a low environmental impact, the design of detachable composite materials and structures as well as the design of mono material structures. This article focuses on waste resulting from the built environment and discusses architectural concepts with a potential of reducing the volume of construction waste and its potential recovery as a construction resource.

A review on achieving sustainable construction waste management through application of 3R (reduction, reuse, recycling): A lifecycle approach

This study shows that there is no systematic review of research progress in literature throughout the field of sustainable construction waste management by 3R (reduction, reuse, and recycling) A lifecycle approach, The need for processes, strategies, rating systems and policies for robust and efficient waste management is widely recognized. The paper aims to evaluate. A review of sustainable construction waste management in Malaysia to maximize the 3R and reduce the disposal of construction waste by implementing a sustainable strategy throughout project lifecycle. Managing landfill shortages and long-term negative environmental economic and social effects of sustainable waste disposal are now becoming crucial for the sustainability of public health and natural ecosystems. To make adjustments, causes and factors responsible for sustainable construction waste management and progress in moving towards sustainability, it is therefore important to define the existing waste management system and causative factors adopted by industries. It allows a major shift in waste management of Malaysia by improvising current technology for waste management in a much more sustainable way. Furthermore, this ongoing research would develop sustainable construction waste procedures to sustain environmental, economic and social development for a Malaysian construction project.

Turning concrete waste powder into carbonated artificial aggregates

In recent years, sustainable management of construction waste has garnered increasing attention. However, most previous studies mainly focused on turning construction wastes into recycled aggregates, whereas, recycling of those construction wastes below 5 mm has often been challenged or ignored. This study attempted to effectively deal with such recycled fine powders by employment of granulation technology to produce artificial aggregates with a diameter of 5–20 mm. The optimal granulation parameters were identified through a systematic experimental test. Moreover, the effect of water and cement content, as well as curing regimes, on the properties (such as shape and strength) of the prepared artificial aggregates was also investigated. More importantly, influence of normal curing and CO2 curing on the strength development of artificial aggregates was examined and compared. In doing so, the scheme of preparation of artificial aggregates with optimal strength was developed. Findings from this study provide an alternative and viable solution to effectively dealing with construction wastes in an environmentally-friendly way and serve as a reference for follow-up studies in the future. Meanwhile, the carbonated artificial aggregate can be potentially used to replace natural aggregates in the preparation of low-strength concrete and blocks.

A Case Study of Sustainable Construction Waste Management in Saudi Arabia

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.

Current practices of construction waste reduction through 3R practice among contractors in malaysia: Case study in penang

The effectiveness of the implementation of construction waste reduction through 3R reflects the sustainability in construction waste management. Weak implementation of construction waste reduction through 3R among contractors will lead to unsustainable construction waste management. Increase in construction waste on landfills is critical especially on islands where land is very limited for solid waste disposal. This aim of this paper is to investigate current practice of construction waste reduction through 3R practice among contractors in Penang, Malaysia. The findings reported herein is based on feedbacks from 143 construction contractors of grade CIDB G7, G6 and G5 in Penang and experts from Penang Local Authority, CIDB in Penang and its Headquarters, National Solid Waste Management Department, and Headquarters of Solid Waste and Public Cleansing Management Corporation. Interviews and questionnaire surveys have been found that 3R practice is not mandatory in construction waste management in Penang. Only 39.8% construction contractors practiced 3R in managing their waste. Therefore, 3R practices should be emphasized in construction industry. Reducing wastes through 3R practices in construction industry is a way forward towards sustainable construction waste management especially in expanding the lifetime of landfill.

Estimating the sustainability returns of recycling construction waste from building projects

The focus of this study is incorporating construction sectors within the concept of sustainable building, which essentially concerns resource management as well as waste management. It is evident that building construction is one of the largest consuming activities of non-renewable resources and natural materials worldwide. Simultaneously, enormous amounts of construction and demolition waste are generated as construction works expand to meet the increasing demand. This is not only considered an economic loss, but also an accelerating environmental threat. Therefore, it has become crucial for construction waste management to evolve away from the long practiced traditional methodology, which has been proven economically and ecologically inefficient, toward sustainable alternatives that prioritize waste recovery over disposal. Within this context, this study addresses the management of construction waste by selecting case studies of actual construction projects and scrutinizing their waste management data. The study took place at the University of Massachusetts—Amherst, where all selected projects conform to the U.S. Green Building Council standards. Thus, the study works on estimating the financial and environmental returns attained by recycling construction waste from such projects. By utilizing the results from the data analysis, the study eventually sets a statistical paradigm with field-based values for typical construction projects to be followed as a guide, indicating how much cost can be saved, and how much landfill volume can be relieved when material waste is recycled. Thereby, the study serves to enhance the sustainable management of construction waste by maximizing the returns of construction waste recovery.

Enhancing Recycling of Construction Materials: An Agent Based Model with Empirically Based Decision Parameters

Recycling of construction material is a valuable option for minimizing construction & demolition waste streams to landfills and mitigating primary mineral resource depletion. Material flows in the construction sector are governed by a complex socio-technical system in which awarding authorities decide in interaction with other actors on the use of construction materials. Currently, construction & demolition waste is still mainly deposited in landfills, as construction actors lack the necessary information and training regarding the use of recycled materials, and as a result have low levels of acceptance for them. This paper presents an agent-based model of the Swiss recycled construction material market based on empirical data derived from the agent operationalization approach. It elaborates on how recycling of construction materials can be enhanced by analysing key factors affecting the demand for recycled construction materials and developing scenarios towards a sustainable construction waste management. Doing so it demonstrates how detailed empirical agent decision data were incrementally included in the ABM model. Raising construction actors' awareness of recycled materials as a decision option, in combination with small price incentives was most effective for enhancing the use of recycled materials. This could lead to a 50% reduction of construction & demolition waste streams to landfills, and significantly reduce the environmental impacts related to concrete applications. From a methodological perspective, although the agent operationalization approach provides a large empirical foundation, incremental model development turned out to be particularly important for the traceability of results and a realistic system representation.

It facilitates accessibility, interfacing, connectivity and information sharing of users in carrying out a wide range of construction waste estimation tasks for sustainable construction waste management. A hypothetical building construction project is used to demonstrate the application and usefulness of the WCWES. • Developing a web-based building construction waste estimation system • Allowing online analytical processing of construction waste • Improving the estimation accuracy of construction waste • Allowing multi-dimensional analysis of construction waste

Reduce, Reuse, Recycle and Recovery in Sustainable Construction Waste Management

Reduce, Reuse, Recycle and Recovery in Sustainable Construction Waste Management

Reduce, Reuse, Recycle and Recovery in Sustainable Construction Waste Management

The construction industry consumes a substantial amount of raw materials in its processes and the output is obviously the product and most importantly the waste material. Other than that, the construction industry is well known as one of the worst environmental polluters. This study is to determine the use of waste minimisation technique in creating sustainable waste management in order to identify the technique which has the most capabilities to reduce on-site waste. The objective of this study is to assess the waste minimization techniques taken from the 4R concept (which includes reduce, reuse, recycle and recovery techniques) in minimizing the waste in construction waste management. The most used waste minimization technique found in the 4R concept would be waste reduction. This shows that the local construction industry has the knowledge necessary to plan out the waste management processes but the implementation is still far from satisfying. Additionally, the findings reveal that because the industry is profit-driven, construction practitioners are motivated by profit to adapt to this techniques.

Investigating factors influencing construction waste management efforts in developing countries: an experience from Thailand

Rapid economic growth and urbanization in developing countries lead to extensive construction activities that generate a large amount of waste. A challenge is how to manage construction waste in the most sustainable way. In the developing world, research on construction waste management is scarce and such academic knowledge needs to be responsive to actual practices in the industry in order to be implemented. As construction projects involve a number of participants and stakeholders, their participation and commitment can have a major influence on the goals of green and sustainable construction for urban development. This study provides a significant step in conducting a very first research of this kind in Thailand by aiming to investigate the level of construction stakeholders' commitment as well as the achievement of construction waste management in order to improve short-term practices and to establish a long-term strategic construction waste management plan. In this study, a structural equation model was employed to investigate the influence of factors that are related to environmental aspects, social aspects, and economic aspect of construction waste management. Concern about health and safety was found to be the most significant and dominant influence on the achievement of sustainable construction waste management. Other factors affecting the successful management of construction waste in Thai construction projects were also identified. It is perceived that this study has potential to contribute useful guidelines for practitioners both in Thailand and other developing countries with similar contexts.
