Waste disposal has become an issue worldwide and the major cause of this issue is considered to be the construction activities producing wastes. Pakistan being the 6 most populated country in the world is considered to have a huge amount of waste due to the various construction and particularly megaprojects and this amount of construction waste is increasing consistently in the country. Pakistan produces of construction waste per year and is increasing annually by 2%. These increasing wastes and issues associated with these construction wastes lead to a crucial need for improvement of waste management practices in the construction industry of the country through various measures. Despite of the large need for waste minimization research in Pakistan, , deductive approach was used, and quantitative method was selected, the present study has used cross-sectional design. The researcher used a sample of 323 individuals and conducted a questionnaire-based study.

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.

Construction industry in Malaysia is growing rapidly with high demand due to vast development and urbanization. Therefore, many commercial and residential buildings are being developed. The increasing number of construction projects in Malaysia will indirectly contribute to the increase of construction waste generation. Thus, waste minimization is an important area of concern in the implementation of the construction waste management in the construction industry of Malaysia. Data collection and observations was conducted at three construction sites which adopt different type of method with different type of building and size of project in Klang Valley. The calculation of the construction waste index generated at these sites is adopted from Poon et al., (2001). Result showed that construction method, size of projects (GFA), type of building, storage method system, human error and technical problem can affect the amount of waste index (debris) and amount of wastage level generated at construction sites. Therefore waste index and wastage level can be used as operational an indicator for waste minimization of the construction activities.

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.

This qualitative study explored the management of waste in commercial and training dental laboratories in order to determine the practices and attitudes of dental technology practitioners and academics towards reusing and recycling dental laboratory waste products, and alert them to the benefits of waste management on the environment. The research objectives were to establish and report on the extent of waste management that entails waste reduction through reusing and recycling, to uncover alternative uses for dental laboratory waste and the possible economic benefits thereof and to influence dental technology industry on environmental sustainability. The research project was conducted in the interpretive paradigm. In the course of this study dental laboratory owners, dental technicians/technologists and academics from the dental technology programme at a training institution were interviewed. Waste handling in dental laboratories was observed in order to gain greater insight as to current practices in laboratories. Thematic content analysis was employed to analyse the qualitative data. This study found that waste management was poorly understood and practiced amongst the dental laboratory owners, dental technicians/technologists and academics. The study adopted a waste management hierarchy conceptual framework which was influenced by the Waste Act (Act No. 59 of 2008). The negative attitudes towards responsible waste management practices and the poor understanding of waste management by dental laboratory owners, dental technicians/technologists were found to be as a result of the poor understanding of the possible impact that waste from dental laboratories can impose on the environment. The perceived lack of participation in constructive waste management legislation by the South African Dental Technicians Council was also seen to be a contributing factor to the negative attitudes towards responsible waste management practices within the industry. This finding reinforced the finding that the dental industry has no knowledge, understanding and desire to understand waste management and, more importantly, to understand that one does not practice things solely for legislative reasons but that there are economic as well as environmental reasons to practice constructive waste management. On the other hand, this study found that the industry was not averse to engaging in environmental friendly practices provided there is financial gain. This was established after the benefits of waste management practices were explained to the industry.


As the intricacy of construction projects is amassed, prospects for tribulations are mounting, depicting negative impact on projects’ cost, time and excellence. Thus, eliciting claims that aredisruptive to projects, time consuming and exorbitant. BIM holds enormousprobable in prosperous claim management practices. The progression of BIM can enrich knowledge sharing for information of a building or facility. It forms a vitalbase for decision making throughout the life cycle phase from the conceptual design to demolition. BIM is also, a valuable multidisciplinary cohesive source of information technology that posts benefits and disputes in the construction industry. The main aspiration of this paper is to appraise how and to what magnitude BIM can help evading and plummeting claims in Jordan construction industry.The paper ran a literature review on recent research, industry reports, and other sources to seehow they identified claims, its classifications, benefits, impacts and challenges of BIM on construction projects.Also, the paper acknowledgedcontemporaneous challenges in the claims field and the construction industry as whole. The attained outcomes have shown that BIM overtakes traditional claim management practices in many aspects including recognizing and investigating claims, where the benefits are comprehended in time and cost savings, less change orders, less rework. Moreover, the information and knowledge management that BIM postulates can improve many aspects of claim management.

Purpose Knowledge management (KM) is the central know how for the construction industry. However, the delivery of construction projects is often plagued by schedule delays and cost overruns due to lack of working knowledge of project personnel. Hence, the need to appraise the practices of knowledge management in the construction industry has become all the more germane. This paper aims to determine the awareness of KM practices in Malaysia-based construction small and medium enterprises, and to investigate the benefits, tools and techniques, and challenges associated with knowledge management implementation so that effective measures can be devised to address them. Design/methodology/approach The research data were gathered using a structured questionnaire survey disseminated in the Klang Valley region in Malaysia. Responses were collected from 107 industry practitioners. The quantitative data are subjected to descriptive statistics, and the ranking with category of significance of the hypothesised variables is determined using the relative importance index (RII) technique. Findings The key benefits of KM practices are predominantly raising efficiency, quality, productivity and decision-making. The most preferred KM techniques are “face-to-face interaction”, “mentoring” and “documents and reports”. The highly significant tools are “groupware” and “telephone”. The major organisational issue hampering the implementation of knowledge management practices is “lack of motivation” while the critical cultural issue is relating to “bureaucracy and hierarchical”, and the vital people issue concerns “lack of trust”. Research limitations/implications The respondents were limited to only small and medium construction enterprises located in the Klang Valley region in Malaysia, which makes generalisation challenging. Practical implications KM provides not only a pragmatic but also a proactive approach to raising the competitive edge and capabilities of a construction company. Identification of the critical attributes of KM provides the basis for project managers in formulating KM strategies to enhance the chances of successful delivery of future projects. Originality/value The study contributes to the debate on the knowledge agenda in the construction industry, particularly from a fast developing economy’s perspective, where an effective KM can further contribute to realising a reasonable level of competitiveness operation.

Background: Indiscriminate waste disposal is a common practice in many cities of Sub-Saharan Africa and these unhealthy practices have made the region face severe environmental deterioration and health implications. The objective of this study is to assess the association between waste management practices and self-reported health outcomes among inner city dwellers in Osogbo.Method: The study is a cross sectional study carried out among 351 household heads using a semistructured interviewer administered questionnaire.Results: Majority (78.6%) of respondents had poor practice of waste management although, most showed concern on likely impacts of poor waste management. Most of them (81.8%) demonstrated positive attitude towards waste management and were willing to participate in organized waste management at low cost. Gender (X2 =7.217, P<0.05), income (X 2=12.140, P<0.05), occupation (X 2=29.034, P<0.05) and level of education were significantly associated with their poor waste management practices. Majority (74%) reported at least one ill health condition, practice and attitude were the major variables implicated in various ill health reported by the respondents.Conclusion: Poor waste management practices are strongly associated with ill health. Keywords: Solid Waste, Management, Self-reported health outcomes, Practices.
