The construction industry is well-known for generating the largest amount of waste amongst other industries, which significantly pollutes the environment. This study, therefore, examines the causes and sources of waste in construction projects, considering activities, inputs, and outputs of each phase of the construction projects’ lifecycle (i.e., concept, definition, deployment, and transition). Thirty semi-structured interviews were conducted with professionals in construction projects in Jordan, including architects, contractors, and project administrators. The findings reveal that waste resulting from construction projects passes across several organized operations from generation to final disposal. Furthermore, waste is generated in small amounts at the early stages of the project construction but grows as the project progresses towards the end. This paper’s key contribution is to supplement the literature on waste management solutions by providing a holistic approach to tackling waste at its root by including waste management strategies across the project lifecycle phases, not only during the construction phase. This is done with a management readiness view to develop a suitable strategy for construction waste minimization and improve the management of construction projects. This study’s practical implication is providing a holistic waste management framework for practitioners to adopt in the early stages of the project.

Illegal Dumping

This nowadays an increasing number of construction projects in Malaysia have contributed to the production of construction waste which has had a negative impact on the environment, especially through illegal dumping. The increasing number of illegal dumping activities is a sign that construction waste management needs to be examined. To date, a comprehensive criterion for construction waste management, in developing countries is still not clearly defined. Therefore, the objectives of this paper are to investigate current illegal dumping activities, and identify the challenges towards reducing illegal dumping activities in the Malaysian construction industry. Hence, this research conducted interviews with 20 expert stakeholders related to construction waste management in order to scrutinise illegal dumping activities in Malaysia. The data from these semi-structured interviews were analysed by content analysis. The findings are used to determine the current challenges for reducing illegal dumping activities in the Malaysian construction industry. The elements in the current findings are potentially to improve construction waste management in order to archive the proper construction waste management. Finally, this findings will help to identify strategies to reduce illegal dumping activities and to enhance challenges towards reducing illegal dumping activities in the Malaysian construction industry.

Abstract Construction projects are characterized by low productivity due to many wasteful activities in construction processes. Wasteful or non-value-adding activities result in quality and profit loss in many construction projects. Consequently, construction needs more effective strategies for process innovation at all stages of the construction project life cycle. Analysis of the current state has shown the possibilities of improving construction processes through the implementation of technologies, methods and procedures of lean construction. Such improvements can help increase the efficiency and productivity of construction projects. Therefore, it is necessary to promote more effective construction waste management by identifying the causes of non-value-adding activities during the construction phase, and apply the gained data to eliminate wastes during the planning phase. The paper presents the most appropriate technologies and methods for collecting data on non-value-adding activities.

The Hong Kong government has implemented various measures to reduce waste, including a waste disposal ordinance, a green manager scheme, a waste reduction framework plan, a pilot concrete recycling plant, waste management systems and a landfill charging scheme. However, there are difficulties in implementing the waste management systems for contractors. This paper examines the existing implementation of waste management systems in the Hong Kong construction industry. Major sources of construction waste, awareness to install environment-friendly activities, benefits, difficulties and recommendations in the implementation of waste management systems are discussed. Questionnaire survey and structured interviews are conducted. Power spectra and bispectra of the survey data are introduced to assess the implementation of the existing waste management systems. It is found that formwork and temporary hoardings are the major sources of construction waste. Improving environmental performance is ranked as the least project scope for construction projects. “Propose methods for reducing waste” is the major benefit gained. However, “Lack of well-known effective waste management methods” is the major difficulty encountered by organisations. “Use of metal formwork”, “Use of prefabricated building components” and “Use of non-timber hoarding” are the recommended methods to improve the existing implementation of waste management systems. Santrauka Honkongo valdžia įdiegė įvairių priemonių atliekų kiekiui mažinti, įskaitant atliekų šalinimo potvarkį, žaliojo tvarkytojo planą, bendrąjį atliekų mažinimo planą, bandomąją betono perdirbimo gamyklą, atliekų tvarkymo sistemas ir sąvartyno mokesčių planą. Tačiau diegiant atliekų tvarkymo sistemas rangovams kyla sunkumų. Šiame darbe nagrinėjamos Honkongo statybų sektoriuje jau diegiamos atliekų tvarkymo sistemos. Aptariami pagrindiniai statybinių atliekų šaltiniai, žinios apie galimą aplinkai nekenksmingą veiklą, taip pat atliekų tvarkymo sistemų diegimo nauda, sunkumai ir rekomendacijos. Atliekamos anketinės apklausos ir nustatytos struktūros pokalbiai. Pasitelkus per apklausas surinktų duomenų galios spektrus ir bispektrus, įvertinamas esamų atliekų tvarkymo sistemų diegimas. Nustatoma, kad pagrindiniai statybinių atliekų šaltiniai – klojiniai ir laikinos tvoros. Aplinkosaugos charakteristikų gerinimas statybos projektuose laikomas mažiausia projekto dalimi. Pagrindinė gauta nauda – siūlomi atliekų kiekio mažinimo metodai. Tačiau didžiausias organizacijoms kylantis sunkumas – žinomų efektyvių atliekų tvarkymo metodų stoka. Gerinant šiuo metu diegiamas atliekų tvarkymo sistemas, rekomenduojama taikyti tokius metodus: metalinius klojinius, surenkamuosius statinių elementus ir laikinas tvoras ne iš medžio.

Waste Management Practices

Hong Kong is a densely populated city with high-rise developments, and as in other metropolitan cities, the amount of waste generated from construction projects in the city is increasing annually. The capacity of existing landfills is expected to be saturated by the 2020s. Construction waste management has been implemented for years but the performance is still not satisfactory. The aim of this research paper is to explore and formulate strategies and measures for effective construction waste management and reduction in highly urbanized cities such as Hong Kong. A desktop study on construction waste management practices was carried out for a preliminary understanding of the current situation in Hong Kong. Semistructured interviews and focus group meetings were further conducted to shed light on how to improve construction waste reduction and management in Hong Kong. The main contributions of this research study are the potential short-term, medium-term, and long-term strategies, which are related to the design stage, tender stage, construction stage, and government support. The five major strategies recommended are financial benefits to stakeholders, public policies in facilitating waste sorting, government supports for the green building industry, development of a mature recycling market, and education and research in construction waste minimization and management.

Post Disaster

Disasters cause substantial damage around the world. This causes serious environmental and economic burden on normal living conditions, reconstruction and general waste collection processes. Within this context, waste management has emerged as a critical issue in responding to a disaster. Thus, this paper addresses post disaster waste management strategies adopted in developing countries and applicability of best global practices in respect of challenges encountered. Comprehensive literature review and field survey among national level institutes in Sri Lanka were conducted to gather information and semi‐structured interviews were used as a method of data collection. The findings revealed that strategies, issues and challenges are varying according to type of disaster, magnitude, location, country etc. Further, poor implementation of prevailing rules and regulations; poor standards of local expertise and capacities, inadequate funds, lack of communication and coordination are identified as key issues encountered.

Purpose The purpose of this study is to identify and assess the waste management strategies that should be priorities for higher education institutions. The role of policy instruments (i.e. purchasing policies and recycling initiatives) in implementing sustainable zero-waste management programs at higher education institutions was investigated through comparison of American top-level and Western Kentucky University (WKU) benchmark universities. Design/methodology/approach Waste minimization-oriented policy instruments implemented at American top-level and WKU benchmark universities were analyzed through policy evaluation techniques. Digital surveys were distributed to sustainability coordinators at WKU benchmark and top-level universities. Semi-structured interviews were conducted with survey participants. Findings It is important to identify well-defined temporal periods with goals and allocated tasks for direct and indirect stakeholders. Time periods should include planning for readiness programs and infrastructural needs, along with performing comprehensive waste characterization studies. As the waste program matures, the creation of integrated waste management policies with specific responsibilities for all stakeholders and departments will be required. Research limitations/implications The sampling of universities evaluated in this research is not representative of all universities in the USA or internationally, as they can vary widely. Yet, general waste management trends applicable to most universities can be gleaned from this research. Practical implications Widely varying zero-waste strategies are readily implemented at universities. A holistic review of successful waste management plans highlights key management approaches that should be included in all plans to ensure their success. Originality/value This study is one of the first of its kind to holistically evaluate policy factors influencing effective zero-waste management at higher education institutions.

Purpose The purpose of this paper is to explore the key practitioners’ level of involvement in the delivery of sustainable regeneration projects in the UK. Practitioners’ level of involvement is a major factor that has and continues to determine the delivery of sustainability outcomes of regeneration projects. Design/methodology/approach The paper adopted a qualitative study that obtained data from 21 key practitioners through semi-structured interviews in exploring practitioners’ level of involvement in the delivery of sustainable regeneration projects in the UK. The semi-structured interviews are conducted with seven practitioners, each from the three construction organisations selected through a purposive sampling approach for the study. Findings The findings identify varied levels of involvement of the key practitioners at the three delivery stages – early, construction and post-construction of the projects. The findings further reveal that clients’ representatives, commercial managers and architects are the most frequently involved practitioners during the early stages of the projects. The findings also indicate that practitioners who have sustainability assigned to their roles and their responsibilities, such as sustainability managers, are the least involved in all the three delivery stages of the projects. Research limitations/implications The study involves interview with 21 practitioners from three organisations delivering sustainable regeneration projects; hence, this could limit the generalisation of the research findings. However, the findings of this study could serve as a useful source of information for the further study in this area. Practical implications The paper is of the view that the level of key practitioners’ involvement in the delivery of the projects will have an impact on their knowledge and will determine how sustainability benefits are promoted and delivered from the projects. Originality/value Although some studies have been carried out on practitioners’ engagement in the delivery of “normal” construction projects, none has focussed on practitioners’ levels of involvement in sustainable regeneration projects. Hence, this study has brought to the fore how the key practitioners tasked with the responsibilities of delivering sustainability benefits of regeneration projects have been involved (at various levels of the project life cycle) in the delivery of these projects.

There are growing calls for construction site activities to be carried out in a sustainable manner. The reason for these calls is not far-fetched in view of the enormous impact such construction activities have on the natural environment. The objective of this study is to examine the effects of green construction site practices on environmental performance of construction projects in Nigeria. The effects of three green construction site practices namely waste management, materials management and energy management on environmental performance were analysed. 168 questionnaires were administered to site managers and project managers from “class A” contractors. The data were analysed using partial least squares-structural equation modelling. The results indicate that waste management has an insignificant impact on environmental performance, while materials management and energy management have positive effects on environmental performance. The results imply that not all sustainable construction site practices lead towards the attainment of environmental performance. The study has both theoretical and practical implication that helps policy makers and contractors to better understand the relationships that exists between these variables of sustainable construction site practices as well as environmental performance. This is essential in order to come out with a better plan for their projects and formulation of appropriate policies.

The issue of sustainability has long been the subject of interest of the architecture engineering and construction sector. All three aspects of sustainability - economic, environmental and social - can be affected through appropriate construction waste management. Construction and demolition waste (CDW) is one of the largest worldwide waste streams, therefore it is given great attention by all stakeholders (investors, contractors, authorities, etc.). Researches have shown that one of the main barriers to insufficiency CDW recovery is inadequate policies and legal frameworks to manage CDW. It is also one of the EU's environmental priorities. Aim of the article is to confirm the economic potential of construction and demolition waste audit processing through case study. A pre-demolition waste audit has been processed for unused building of shopping center in the town Snina in Slovakia. Subsequently, a comparison of economic parameters (waste disposal costs and transport costs) of recommended CDW management was performed. This comparison confirmed the economic benefits of environmentally friendly construction waste management methods according to the waste audit results, which will also increase the sustainability of construction projects. In addition, the cost parameters of selected waste disposal methods could be another dimension of building information modelling.
