The sustainable transition towards the circular economy requires the effective use of artificial intelligence (AI) and information technology (IT) techniques. As the sustainability targets for 2030–2050 increasingly become a tougher challenge, society, company managers and policymakers require more support from AI and IT in general. How can the AI-based and IT-based smart decision-support tools help implementation of circular economy principles from micro to macro scales?

This chapter provides a conceptual framework about the current status and future development of smart decision-support tools for facilitating the circular transition of smart industry, focussing on the implementation of the industrial symbiosis (IS) practice. IS, which is aimed at replacing production inputs of one company with wastes generated by a different company, is considered as a promising strategy towards closing the material, energy and waste loops. Based on the principles of a circular economy, the utility of such practices to close resource loops is analyzed from a functional and operational perspective. For each life cycle phase of IS businesses – e.g., opportunity identification for symbiotic business, assessment of the symbiotic business and sustainable operations of the business – the role played by decision-support tools is described and embedding smartness in these tools is discussed.

Based on the review of available tools and theoretical contributions in the field of IS, the characteristics, functionalities and utilities of smart decision-support tools are discussed within a circular economy transition framework. Tools based on recommender algorithms, machine learning techniques, multi-agent systems and life cycle analysis are critically assessed. Potential improvements are suggested for the resilience and sustainability of a smart circular transition.

Research studies related to sustainability and green building have made monumental contributions to the concept of sustainable construction (SC) in Nigeria. This paper therefore aims to present a historical review of the development of SC in Nigeria over a 10 year period. The review also provides constructive perspective on the benefits of SC and the present state of enforcement of green building in Nigeria.

A historical review strategy was applied to the study. Using secondary data sources, 47 influential journals from emerald, scopus and science direct database focusing on “SC”, “sustainability” and “green building” in Nigeria between 2012 and 2022 were used for the analysis.

The analysis deduced that the development of SC in Nigeria have undergone a triple period of development: the inception period (2012–2016), the transition period (2016–2020) and the advancement period (2020–present). The review juxtaposes the three timeline to show rapid growth in the awareness of SC, but revealed moderate levels of implementation in some major cities in Nigeria. Therefore, the author finds and argues that the advancement of SC in Nigeria can be achieved through the synergy, commitment and active roles of researchers, academics, practitioners, policy makers and the government in enforcing existing green policies.

The study is the first academic paper to undertake a decade long historical review of SC in Nigeria. This review provides an up-to-date understanding of the developments, changing dynamics and future progressions in the field of SC in Nigeria.
