Construction and demolition waste are the major issue as a direct consequence of increased global urbanization. It impacts the environmental efficiency of the construction industry, contributing to 35% of the global landfill. This research considers the two main fundamental factors affecting the demolished building waste management, which are the management hierarchy including the 3R strategies and the project life cycle and management tools. The inappropriate treatment and disposal of Construction and demolition waste give rise to the environmental pollution, land price, and natural resource consumption. This paper scrutinizes the concept of Construction and demolition waste management and review the extant studies in the managerial areas of Construction and demolition waste. These findings are aimed at clarifying the current and future practices of Construction and demolition waste management practices with an understanding for the sustainable governance. Keywords: Construction and demolition waste, management, review.

The rules and regulations on waste management in the construction and demolition sector are analyzed corresponding to the present scenario of C&DW in India. C&D waste from construction sites has emerged as a significant threat to India because of its severe footprint on the environment. Vast quantities of construction waste will have unfavorable consequences on the surroundings if they are not properly managed. Therefore it is necessary to manage the development of C&DW by the experts within the construction industry. The approach represented is specialized in rules and regulations on waste management so that the environmental impact of construction activities can be minimized.

Waste Management Practices

Construction wastes pose challenges to contractors and clients of construction projects globally, with significant negative consequences on the environment. This study investigates the environmental waste management practices (EWMPs) of contractors on construction sites. The objectives are to determine the level of awareness and adoption of EWMPs. The population of the study was construction professionals on sites in Lagos State, Nigeria. Random sampling technique was used to select 63 companies out of the 126 construction companies in categories C, D and E of firms registered with Lagos State Public Procurement Agency. The targeted respondents were construction professionals in the selected companies. Questionnaires were used to collect data from respondents. Descriptive statistics tools, including mean, percentage and frequency were used for analysis. The study's findings reveal that contractors are aware of about 28 out of the 47 EWMPs identified from literature. These include good site materials storage, ordering exact amount of materials and checking deliveries properly. It also reveals the strategies that are not used as belonging to material exchange/recyclers' association, polluter pays principle, usage of self-contained mini or mobile concrete crusher. It is concluded that although contractors are aware of 28 EWMPs, 26 EWMPs are used on construction sites which are 60% and 55%, respectively. It implies that awareness determines the usage of the EWMPs. The implication is that if the awareness of EWMPs is increased, the implementation among construction contractors will be improved. It is therefore recommended that professionals should increase their awareness and usage of neglected EWMPs. This can be achieved through construction firms, governments and institutions sponsoring training of professionals on EWMPs. Additionally, polluter pays principle and recyclers’ association should be enforced in project implementations. This can be achieved through government legislation and government regulatory policies for project procurements.Keywords: Awareness; Best practices; Construction sites; Nigeria; Waste management.

Using Data

Rapid industrial development, mega construction projects and increased immigration are some of the reasons that the State of Qatar has recently generated an unprecedented amount of construction and demolition (C&D) waste in the country. The State is racing towards the Fédération Internationale de Football Association World Cup 2022, a fact that requires additional construction, for which it is expected to increase its rate of waste generation. Compared to other regions, there are relatively few studies in the literature that report on the C&D waste management issues of Qatar. The present work begins to address this gap by providing insights into the current state of C&D waste management practices in Qatar and by providing a mini-review on the benefits of using recycled aggregates which have only recently been allowed locally by Qatar Construction Standards. A Strengths, Weaknesses, Opportunities, and Threats analysis has been implemented, using data and information from various sources including governmental reports, industries, local waste management companies, as well as reported interviews with relevant stakeholders. Finally, several strategies were proposed and developed that could potentially be implemented by stakeholders and decision-makers, so as to improve the current status by encouraging more sustainable and viable practices.

Waste Management Practices

Rapid population growth and urbanization have led to an increase in Construction and Demolition (C&D) waste, prompting government and industry bodies to develop better waste management practices. Waste trading has emerged as a targeted intervention to divert waste from landfill sites and create a second life for waste material. This paper examines key barriers and enablers influencing the creation of a marketplace for waste trading. A systematic literature review was undertaken to examine global efforts in creating a marketplace for C&D waste. A framework on enablers and barriers for developing a marketplace for C&D waste emerged from the review, based on market-based, operational, and governance factors. References demonstrated that markets for materials such as glass and metals have already been established, but there are increasing marketplace opportunities for other recycled materials. Technology-based market applications are emerging as targeted interventions to facilitate online trading, which will provide a more accessible and user-friendly marketplace for sellers and buyers. Further research should test the complex interactions between people and technology associated with online waste trading platforms, as well as help develop the business case for a C&D waste marketplace.

Potential Benefits

A study was conducted to identify the primary sources and types of construction and demolition (C&D) waste, determine current and potential management actions which can be applied to the respective wastes, and assess the potential benefits, barriers, and recommendations towards the implementation of a C&D waste management plan in Trinidad and Tobago—a Caribbean Small Island Developing State (SIDS). This process is lacking locally, and will benefit decision makers and other stakeholders in proper management of C&D waste. Currently, the primary method of waste disposal is landfilling. The structured questionnaire survey method was used to collect the data, and data were analyzed by descriptive statistics and one-way ANOVA with appropriate post-tests. Results showed that wood, plastic, cardboard, gypsum board, and steel were identified as the most wasted materials on site, with the top sources being attributable to design, operations, and residual causes. It can be inferred that if materials are not being reused, they are being landfilled, as these were the two primary waste treatment methods identified as being used for all materials. If waste management practice gathers enough support from all respective authorities and stakeholders, the general consensus is that all materials listed have recycle/reuse potential in Trinidad and Tobago. The top agreed upon advantages of C&D waste management were all directly related to sustainability, and the barriers to implementation identified were related to general lack of support from respective stakeholders and authorities. From the overall results, it can be concluded that there is not enough evidence to suggest that larger contractors have more positive attitudes and behaviors towards C&D waste management. Although the data are local, the findings from this research can be used as guidelines by the other Caribbean SIDS nations in formulating/comparing their own waste management practices.
