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.

In China, a common practice for construction waste management is to dispose of it in landfills. A 5% construction waste recycling rate and ongoing insufficient landfilling practice resulted in decreased environmental and socioeconomic well-being. Management hierarchy that starts with rethink, redesign, reduce, reuse, refurbish, recycle, incineration, and finally disposal is a probable strategy to facilitate construction waste minimization in China. The green building concept pursued by China also served as a promising tool in evaluating the performance of Chinese green buildings. Barriers include lack of standard operating procedure in waste minimization, immature recycling technology and an undeveloped recycling market, leading to poor performance in construction waste minimization. Several strategies are proposed to ameliorate the current condition in China's construction sector. Even though results reveal that China falls behind in the engagement of green building compared to developed countries, green materials are utilized in various building structures such as flooring, roofs, walls, and outdoor pavements. Lastly, the benefits and shortcomings of two green material technologies, in particular material selection and recycling, applied in China were reviewed.

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.

Effective waste management is an important aspect of green building development. However, a number of studies find that construction waste minimization actions are not satisfactorily performed in practice. Thus, it is of significance to identify the driving factors that influence construction practitioners' waste minimization behavior. This paper aims to explore the driving factors by comparing the affecting factors and construction waste minimization behavior between Hong Kong and Shenzhen. Firstly, through a comprehensive literature review, potential affecting factors were categorized into five groups: background information variables, construction waste minimization intentions, economic viability, governmental supervision, and project constraints. Based on the identified factors, a questionnaire was initially designed and then refined through a focus group meeting with three experienced experts. A total of 166 questionnaires were collected and non-parametric tests (Mann-Whitney U Test and Kruskal-Wallis Test) were conducted to investigate the underlying driving factors. Results revealed that background information variables play insignificant roles in construction waste minimization. Compared with other affecting factors (i.e., waste minimization intentions, governmental supervision, project constraints), economic viability is the most important driving factor that determines construction waste minimization. Results suggested that local governments should make policies that increase practitioners' profit, rather than just increasing their intentions or regulating waste management behavior.
