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.

Hierarchy Process

Construction and demolition waste (CDW), as the main consequence of construction and demolition (C&D) activities, has severely affected our sustainability needs. However, construction and demolition waste management (CDWM) lacks the integration of sustainability concepts. Thus, there is a great need to include sustainability dimensions in CDWM to reach sustainable construction and demolition waste management (SCDWM). This study aims at empirically investigating SCDWM by analyzing the impacts of factors that contribute to sustainability aspects of CDWM on waste management hierarchy (WMH), including reduce, reuse, recycle, and disposal strategies. According to the literature, 26 factors were initially identified and grouped under four categories, namely environmental, economic, social, and administrative, that contribute to sustainability aspects of CDWM. Subsequently, a pilot test was performed to assess the significance and applicability of these factors in the Malaysian construction industry by implementing the express analytic hierarchy process (EAHP). Then, a questionnaire survey was performed to collect data from 132 construction companies involved in CDWM. Partial least squares-structural equation modeling (PLS-SEM) was used to test the hypothetical relationships by applying SmartPLS software. Results demonstrated that the economic aspect of CDWM (main category) and “public environment contamination due to illegal waste dumping” (sub-category) were the most influential factor in SCDWM in Malaysia.

The presented study is focused on the verification of a Building Environmental Assessment System (BEAS). A total of 13 detached family houses representing typical construction sites in Slovakia were chosen for analysis, evaluation and certification by using a BEAS which contains several main fields: A—Site Selection and Project Planning; B—Building Construction; C—Indoor Environment; D—Energy Performance; E—Water Management; and F—Waste Management. The results of this study show that the current construction method for family houses does not respect the criteria of sustainable construction as much as it possibly can. The reason for this is that investment costs for construction are prioritized over environmental and social aspects. Therefore, one house with a score of 1.10 is certified as BEAS BRONZE, ten family houses with scores of 1.56–2.88 are certified as BEAS SILVER and only two family houses with total scores of 3.59 and 3.87, respectively, are certified as BEAS GOLD. The overall results show that the weakest fields of sustainability are Waste management, Energy performance and Building construction. The best-rated fields are Site Selection and Project Planning, Indoor Environment and Water Management. In the future, it is essential to pay attention to those areas where the sustainability criteria have not been reached, as well as to raise project teams’ awareness of sustainability issues and subsequently to transfer them to building practices.

The article considers the features of complex optimization of construction waste management and defines its role in the formation of the concept of "sustainable construction". The authors note that in order for the construction, demolition and waste management industries to remain competitive in the global market, they must continue developing and implement innovations in the supply chain to improve efficiency, sustainability, and reduce energy, waste, and resource consumption. This requires serious research on intelligent, mobile, and integrated systems. Radically advanced robotic artificial intelligence systems for sorting and processing must be developed with an emphasis on the required reuse of materials and components. Many industries face an uncertain future in which the applicability of today's technological constraints cannot be assumed. The construction industry is likely to be significantly impacted by the capabilities of transformative technologies such as artificial intelligence, additive manufacturing, nanotechnology, virtual reality, and robotics. The application of such technologies presents significant opportunities for this industry.

There is a lack of awareness and knowledge among the Malaysian construction industry about waste management reduction. Numerous nations worldwide have understood and have incorporated the concept of the 3R (reduce, reuse, and recycle) in waste management, and it has worked out well. This study investigated construction waste issues and developed a model for sustainable reduction by applying 3R using a partial least squares structural equation modeling PLS-SEM in Malaysia. The research methodology adopted the quantitative and qualitative approaches by sending a survey questionnaire to the relevant stakeholders to obtain their views or perceptions and interviewing an expert in the related field about waste reduction in the Malaysian construction industry. Three hundred thirty questionnaires were collected within six months of submission. The significant factors are determined using mean ranking for the reduce, reuse and recycle elements. Based on the results, the exploratory power of the study model is considered sustainable with R2 values of 0.83%. At the same time, the results of relationships between improving factors, policy-related factors, construction waste generated, and sustainable construction waste reduction were significant. Also, the findings revealed that the top factors for waste generation on reducing, reusing, and recycling are lack of design and documentation, and lack of guidance for effective construction waste-collecting. The paper will explore different and dynamic practices, such as recycling, reuse of construction waste management cost reduction, enabling stakeholders and managers to estimate and quantify the actual size of CWM costs and benefits for sustainable development goals.

This review presents “a state of the art” report on sustainability in construction materials. The authors propose different solutions to make the concrete industry more environmentally friendly in order to reduce greenhouse gases emissions and consumption of non-renewable resources. Part 1—the present paper—focuses on the use of binders alternative to Portland cement, including sulfoaluminate cements, alkali-activated materials, and geopolymers. Part 2 will be dedicated to traditional Portland-free binders and waste management and recycling in mortar and concrete production.
