Seven-dimensional automated construction waste quantification and management framework: Integration with project and site planning

Construction waste management and inventory are lacking in the Jordanian construction sector. With the dramatic population growth, the construction sector plays a significant role in developing the Jordanian economy. This article aims to develop a model to quantify construction and demolition (C&D) waste based on either project hyper-categorization or waste type, and to measure the degree of awareness and readiness of local contractors to benefit from C&D waste. Therefore, it classified projects further into construction and infrastructure projects. The construction project is also classified as new construction, renovation, or rehabilitation. These classifications help improve the management of construction waste. Moreover, a survey was conducted among construction stakeholders to increase awareness and assess their perceptions and readiness to adopt C&D waste management activities in their current or future projects. Finally, a strengths, weaknesses, opportunities, and threats (SWOT) analysis was conducted to heighten major stakeholders' awareness about the challenges of C&D and to develop an effective C&D waste management plan. The results of this research can help both decision-makers and stakeholders in the construction sector properly classify their waste, reduce and manage generated C&D waste, and lower overall costs. Finally, the SWOT analysis identifies hidden opportunities to promote and develop a future C&D waste management at all levels. Meanwhile, revenue from recycling C&D waste is expected to be about US$4.2/m2 of construction.

The tremendous quantity of waste produced from construction and demolition is a major cause of environmental degradation. This quantity tends to increase due to the rapid growth of building development and renovation. Meanwhile, construction waste management is a complex and costly process due to the fact that it requires different kinds of resources such as money, land, and technology. It is often ignored by all project participants even though it is an essential element of construction project management. However, it has been discovered that modern construction waste management is structured based on the concept of circular economy which focuses on eliminating construction waste and maximizing the value of materials. Therefore, this research proposes an innovative framework to implement the circular economy using building information modeling (BIM) in order to improve the construction waste management process. This involved a thorough review of past literature to identify the implementation of the concept of circular economy, waste management, and the application of BIM, also the research gaps observed were used to develop the functionality of the proposed framework. The five functionalities include (1) visualization and data integration, (2) direct construction waste quantity take-off, (3) BIM-based sorting system and selection of appropriate disposal parties, (4) estimating cost and schedule of waste disposal, and (5) simulation and monitoring report. This BIM system was designed to analyze material waste, quantity, disposal time, and waste treatment based on project conditions, material quantities, and schedule. It can also be used to plan and monitor the construction waste process, thereby making it possible to avoid the disruption of productivity and project time usually caused by unplanned waste management activities. Moreover, the proposed on-site sorting system also has the ability to facilitate the adoption of the circular economy concept during the construction phase.

Waste is considered as an end of city product’s life as well as a burden in modern society. The government of Hong Kong and Singapore are striving to improve construction and municipal solid waste management since 1960. At the same time, waste policies lead to social and economic controversies among citizen. How can we develop better sustainable waste management strategies? Will these methods lead to different level of environmental and economic problems? Whilst previous research in construction and municipal waste mainly sheds light on the methods of construction waste management on sites by interviews, surveys and case studies, few research has been conducted to study the digital information available in academic journal database and World Wide Web. This chapter tries to fill this gap by discussing (1) whether the government’s waste management strategies are sustainable; (2) the efforts on construction and municipal solid waste made by the governments in Hong Kong and Singapore.

Abstract. The purpose of the article is to study the global experience of regulatory and legal regulation of construction and demolition waste management to determine measures to ensure the use of secondary raw materials from construction waste in Ukraine for the restoration of objects damaged and destroyed as a result of military actions and the construction of new buildings. The results of the study of the experience of developed countries regarding the attraction of construction and demolition waste for reuse and processing into secondary raw materials are presented. Analytical studies have established that Directive 2008/98/EC of the European Parliament and the Council provides for a target increase by 2020 of the share of non-hazardous construction waste prepared for reuse and recycling to at least 70% by weight, as well as promotion of recycling by selective removal of materials and creation of sorting systems. The direct requirements of the regulatory and legal regulation of construction waste management during the construction of facilities are outlined. In some states, direct requirements for handling construction waste have been established: in new construction, a certain percentage of products from recycled waste must be used; ban on landfills for construction waste that can be used for processing into secondary raw materials; the minimum area of buildings, during the construction of which mandatory disposal of waste is regulated; the minimum volumes of construction work are legally defined, the excess of which determines the need for builders to sort and process construction and demolition waste. The lack of specific target indicators for the collection, sorting, processing of construction and demolition waste, as well as the use of secondary raw materials obtained from them, was emphasized in the normative legal acts of Ukraine on waste management.

Construction waste issues have raised considerable concern in recent decades. Green building (GB) has been adopted around the globe as a strategy to curtail building-related environmental issues, including construction waste. Particularly in China, with the soaring construction activities tied to urbanization and urban regeneration, massive construction waste has been generated, imposing tremendous pressure on the industry and beyond. China is also vigorously pursuing a national GB strategy, but its effects on construction waste management (CWM) are yet to be confirmed. This paper evaluates CWM performance in GB by putting the dyads into China's particular Political, Economic, Social, and Technical (PEST) context. By analysing a total of 310 LEED (Leadership in Energy and Environmental Design) accredited GB projects in China, it is surprisingly discovered that GB does not prominently improve CWM. The paper goes further to understand the causes of the mediocre CWM performance, by conducting ten semi-structured interviews with GB and CWM practitioners in China. Finally, a comprehensive PEST analysis is conducted to discuss the situation in the context of China. Factors such as (a) incomplete CWM regulations in China, (b) lack of economic incentives, (c) lacklustre awareness about CWM, and (d) lack of advanced technologies, caused the CWM performance in GB. Based on the PEST analyses, some targeted strategies are also recommended. This study is of benefits to both researchers and practitioners in the GB industry.

Purpose. To improve the existing system for managing construction waste generated due to the damage (destruction) of buildings and structures as a result of hostilities, with the aim of developing a long-term, comprehensive strategy for construction waste management, taking into account current conditions and challenges. The methods. An analysis of the main problems and methods of construction waste management in Ukraine was conducted, highlighting the advantages and disadvantages. A construction waste management scheme was developed; a SWOT analysis (Strengths Weakness Opportunity Threats) of waste management in the Dnipropetrovsk region was carried out, taking into account regional specifics. Results. An analysis of the problems of effective construction waste management allowed us to identify comprehensive actions and outline the main ways to improve the effective management of construction waste generated due to the damage (destruction) of buildings and structures, taking into account the experience of other countries and the specifics of the situation that has developed in Ukraine as a result of hostilities. The originality. The processing of construction waste has significant internal potential for expanding the use of recycled materials in Ukraine. Construction waste management can solve not only environmental problems but also become a source of efficient use of available resources, open up new opportunities for business, create a market for secondary building materials, and contribute to the transition to a circular economy. Practical implementation. Integration into a new unified innovative system involves solving a whole range of issues and problems related to the need to improve methods of managing construction waste generated due to the damage (destruction) of buildings and structures as a result of hostilities. This will allow the development of a transparent legislative and legal framework, create an effective market for secondary building materials, rationally use available resources, solve important environmental problems, and implement large-scale restoration projects based on the principles of a circular economy.

Benchmarking construction waste management performance using big data

Enhancing performance of construction waste management: Factor analysis from the building contractors’ perspectives

<p>The management of construction waste in large cities carried out by the public administration presents some difficulties that have been increased due to the housing policy developed by the federal government. These problems have affected not only the generation, management, but also the final destination of the waste products. The objective of this study was to investigate the conflicts experienced in João Pessoa city through the quantification found in the Civil Construction and Demolition Waste Management Projects (PGRCCD) present in the Environmental Licensing processes requested in Environment Secretariat of João Pessoa (Semam). In João Pessoa, the situation experienced in the years 2014 and 2015 reflects the national scenario. In 2014 the upswing in the sector resulted in the generation of about 712,101.49 m3 of construction and demolition waste (RCDs). It became a problem because there was evidence of correct disposal of this waste occurring in only 8,471.50 m3 of the estimated total. In 2015, following the national slowdown due to the political-financial crisis, the generation of construction waste decreased considerably. As a result of that there was only an amount of 31,788.88 m3 of construction and demolition waste. However, the final waste disposal verification exceeded the waste generation quantification of the year, of 40,246.46 m3. This made us refer back to former problems’ resolutions. Based on the information from this period it can be said that the process of implementing shared management skills requires adjustments, improvements and technological investment in the traceability of waste disposal that includes the design of the architectural project and the project delivery for this would mean improvements for the city and less environmental impacts.</p>

Throughout the years, the construction industry plays a significant role in helping the nation to achieve the main goal of sustainable development in the lives of society in Malaysia. With the demands of major residential housing project developments, it shows that the construction sector is being expanded and developed. Moreover, it has been observed that the construction waste is one of the priority waste streams. Due to the increasing population that is actively involved in economic activities and the modernisation of the country, the types of construction wastes that is being produced is becoming more complex and has yet to be identified. Therefore, the established system to record quantitative data for the generation of construction waste has yet to be formally standardized and is still lacking across much of Asian and developing countries. To address this need, the study on the types and composition of construction waste generated is carried out as a logical first step towards assisting the construction waste management through the categorization of construction waste in Klang Valley. Throughout this study, useful information concerning waste assessment data is necessary to achieve a better understanding of construction waste obtained. Case studies involving quantification and classification of construction waste for several on-going residential housing developments in Klang Valley, Malaysia have been presented. This paper concludes with the identification of database information concerning the quantification of local construction waste which was developed for the current practices of construction waste management.

Sustainable construction and demolition waste management in Somaliland: Regulatory barriers lead to technical and environmental barriers

The use of various tools for construction waste management throughout the planning and design (P&D) stage has several advantages. According to some research, building information modelling, or BIM, could be a valuable tool for predicting waste. This paper discusses how BIM could be used for pre-empting waste and reducing the course of the planning and design process of constructing a building. In Malaysia, a questionnaire survey of 340 construction experts was undertaken. Simultaneously, a regression analysis was carried out in order to determine the impact of BIM on the management of construction waste during the planning and design stage. This research could help many stakeholders in the construction industry to recognise various aspects of waste management, beginning with the planning and design stage of a project, which can be represented by designing a model that can be applied to mitigate waste during the construction of a building.

This research explores the constructional waste management practices in Pangasinan, aiming to develop a policy brief that addresses key issues in construction-related waste management. The study focuses on profiling the municipalities of Pangasinan’s current construction waste management system, including the adequacy of human resources involved in constructional waste management system, and existing policies, activities, and programs influencing waste management as perceived by selected Civil Engineers in the province of Pangasinan. It also examines how constructional waste management practices are monitored and identifies the types of waste typically generated in construction projects by the local and provincial government, such as concrete debris, scraped asphalt, excavated materials, packaging waste, and fuel waste like oils. Moreover, the research assesses the level of awareness among local government personnel regarding waste management protocols and evaluates the seriousness of challenges faced in implementing effective constructional waste management strategies. The study is limited to constructional wastes and specific materials commonly encountered in road and building projects. Based on the findings, a thorough recommendation will be proposed to improve waste management practices, promote sustainable construction, and enhance policy formulation for the different local government units, including the Department of Public Works and Highways, of Pangasinan

The circular economy (CE) concept presents an innovative solution, aiming to transform the traditional linear system into a regenerative system. Thus, it is considered as a potential means of addressing the limitations in construction and demolition (C&D) waste management (WM) practices. However, the lack of clarification among stakeholders regarding the application of CE is one of the significant problems in introducing CE practices to the construction industry. Thus, this research aims to develop a framework for CE-based C&D WM via stakeholder engagement (SE). Through a qualitative approach, data were collected through preliminary interviews, case studies, and a focus group, analysed via content and thematic analysis. Exploring the SE link, key mechanisms to integrate CE-based C&D WM in construction projects are revealed. The proposed SE framework promotes sustainable construction, offering stakeholders definitive guidelines for incorporating CE principles. In an industry with significant waste and environmental concerns, a CE focus on resource optimisation and waste reduction is crucial and influential.

This study provides a qualitative comparative assessment of the Circular Economy (CE) framework and the Green Pyramid Rating System (GPRS) as emerging approaches for improving construction and demolition waste (CDW) management in Algeria. The research aims to examine the advantages, limitations, and contextual applicability of both systems, and to explore their potential integration into a coherent sustainability model suited to the Algerian construction sector. A descriptive–comparative qualitative methodology was adopted, combining a systematic literature review, a case study of Algeria, and expert input collected from 21 professionals representing engineering, environmental management, and policy sectors. Data were analysed thematically and synthesised using a structured SWOT matrix. Findings show that CE offers strong potential for resource efficiency, waste minimisation, and job creation, yet remains constrained by limited recycling infrastructure and high initial investment requirements. In contrast, the GPRS provides measurable sustainability criteria at the project level and strengthens energy and resource efficiency, but suffers from low national adoption, limited professional capacity, and competition from global rating systems. Results also indicate that integrating CE’s macro-level material circularity with GPRS’s micro-level performance standards could enhance environmental outcomes and support Algeria’s transition toward sustainable construction practices. The study recommends expanding recycling infrastructure, developing regulatory incentives for green construction, localising GPRS criteria for the Algerian context, and adopting a hybrid CE–GPRS implementation roadmap to advance national CDW management strategies.
