The circular economy has become a significant policy in many countries around the world. In order to achieve a circular economy, wasteful use of resources must be reduced and waste products from manufacturing must be reintroduced into production systems. It is, however, impossible to totally avoid scraps from the production of most goods. This chapter describes an investigation of current practices of 108 small-and-medium-sized manufacturers (SMEs) regarding their use of solid wastes or scraps. Of particular interest are the scraps generated by SMEs because they comprise 98.5% of all manufacturers in Thailand. Despite concern regarding the growing volume of scraps from production lines, this study collected data from both factory visits and from manufacturers and found that waste reclamation policies among SMEs are rare. Most factory owners resort to selling off-cuts to formal and informal recyclers as well as dumping scraps in the city’s bins. Despite the general recognition of the growing creative industry in Thailand, the use of design has not been considered as a potential solution to this problem by manufacturers. Since failures in scrap reclamation schemes for product designs also hinge on market prospects and opportunities perceived by manufacturers, market strategies in the green economy must be devised. Only then can Thailand achieve circular material flow in its industrial sector.

This article observes how, in today’s common building practice, design practitioners seldom utilize the expertise of researchers in building‐related fields. The lack of the collaboration may be due as much to the “applicability gap” between research and practice as to the lack of a clearly defined role of researchers in building design. Most institutions’ research groups and facilities planning offices are generally not set up to collaborate with the design and engineering professionals. This study, however, found design teams’ collaboration with academic and research institutions to be instrumental in the successful development and implementation of technological innovations in architectural projects. It discusses the findings and provides partnership strategies between the institutions, as large‐building owners, and the building professionals, as design providers.

The lead user concept developed by Eric von Hippel is perhaps the only formal method designed specifically for identifying innovators. This paper discusses the applicability of von Hippel's lead user concept in the architectural industry where technological innovations are necessary yet gravely scarce. In order to examine the applicability of the lead user method, a set of seven case studies of novel energy efficient solutions found in built facilities in Europe and North America were analyzed. The result of the study indicates that the method may not be suitable for identifying the likely source of innovation if the innovation does not focus on an individual's needs; combined efforts are mandatory to create the innovation; and the size and complexity of the innovation make it impossible for a user or an individual to deliver or to test it out on his/her own. The concept of lead provider is introduced and several characteristics are identified.

The purpose of this paper is to develop a framework to facilitate early supplier involvement (ESI) as an approach for reducing construction waste (CW) generated during the design process.

A research methodology consists of literature review, case studies and survey questionnaire was designed to achieve the abovementioned aim. First, the literature review was used to investigate CW, CW generated during the design process, the design process and ESI. Second, two construction projects were analysed to investigate the role of ESI towards reducing CW generated during the design waste. Third, a survey questionnaire was carried out with a representative sample of architectural design firms (ADFs) in Egypt to examine their perception and application of ESI towards reducing CW generated during the design process. Based on the results of the above, the research developed a framework to facilitate ESI during the design process to reduce CW.

Through literature review, the research highlighted the causes of CW generated during the design process and identified the benefits and challenges that encounter ESI in ADFs. Results of data analysis showed that “last-minute changes due to client requirements” was ranked the highest challenges of ESI in ADFs in Egypt followed by “lack of design experience”. Moreover, “providing technical information about materials and equipment and their capabilities” was ranked by respondents as the highest contributions of suppliers during the design process which leads to waste reduction followed by “better estimation of materials and costs”. Finally, respondents stated that “resistance of ADFs to include suppliers in the design phase” was ranked the highest challenge of ESI in the design process followed by “no clear guidelines or policies that organise ESI”.

Because of the conceptual nature of the proposed framework, it has to be tested and validated to ensure its capability to overcome the challenges of ESI as an approach for reducing CW generated during the design process.

This research presents a practical solution to the problem of CW generated during the design process through ESI.

The research discussed the causes of CW originated from the design process and the benefits and challenges of ESI in ADFs. It investigated the perception and application of ESI in ADFs in Egypt. The proposed framework which was designed to facilitate the integration of suppliers in the early stages of the project life cycle represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

In a conventional sense, information technology has frequently been considered a source of Lean waste management. However, as the corporate world evolves, new models that provide a competitive edge by merging technical breakthroughs with the Lean paradigm must be developed. Enterprise resource planning (ERP), which is such technological advancement, is found to be highly influential for Lean implementation. However, there is a dearth of literature on the adaptability of ERP to minimise Lean waste in the construction industry. This paper, therefore, aims to investigate the possibility of applying ERP to minimise Lean waste in the construction industry.

The study used a qualitative approach, consisting of fifteen (15) expert interviews and code-based content analysis was used to analyse the empirical data.

The findings revealed the challenges faced when applying ERP with the Lean concept and the strategies that would help overcome the challenges. Most of the challenges could be overcome through training and awareness programmes and proper team management. The study also found that ERP could be applied with Lean to eliminate waste generation in the construction industry.

This paper contributes to the theory by providing an evaluation of the possibility of adopting ERP to eliminate Lean waste in the construction industry. The study will contribute to new knowledge related to strategies for proper use of ERP for Lean waste minimisation, which will be useful for future researchers in the area.

The purpose of this study is to investigate barriers to the adoption of digital technologies (DTs) in the circular economy (CE) transition in the construction industry. The aim is to quantitatively investigate what the barriers to DTs-driven CE are in the Nigerian construction industry.

A review of existing literature identified 32 barriers to DTs-led CE. A well-structured quantitative research questionnaire was developed and administered to construction experts using a convenient sampling technique via hand delivery and Google form. The gathered data were analysed using arrays of both descriptive and inferential statistical methods.

The study revealed that the awareness of the digitalisation of CE is high, but the adoption is low. Five themes of the leading 10 factors responsible for the low adoption of DTs in CE transition in the Nigerian construction industry are (1) finance and demand barrier, (2) data management and information vulnerability, (3) skills shortage and infrastructure challenge, (4) poor government and management support and (5) interoperability and resistance problems.

This study could be helpful to decision-makers and policy formulators, which would provide an avenue for higher adoption of DTs in CE transition in the construction industry, better performance and environmental protection. It also provides a foundation for further research efforts in Nigeria and other developing countries of Africa and beyond.

Studies on the barriers to DT adoption in CE transition are still growing, and this is even non-existent in the Nigerian construction context. This offers a unique insight and original findings by pioneering the identification and assessment of barriers to the digitalisation of CE transition in Nigeria’s construction industry.
