Abstract

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

The transition to a circular economy in the built environment is key to achieving a resource-effective society. The built environment can be made more circular by applying circular building components. The purpose of this paper is to present a design tool that can support industry in developing circular building components.

Design/methodology/approach

The tool was developed and tested in five steps. In Step 1, the authors analysed existing circular design frameworks to identify gaps and develop requirements for the design tool (Step 2). In Step 3, the authors derived circular design parameters and options from existing frameworks. In Step 4, the authors combined and specified these to develop the “circular building components generator” (CBC-generator). In Step 5, the CBC-generator was applied in the development of an exemplary component: the circular kitchen and tested in a student workshop.

Findings

The CBC-generator is a three-tiered design tool, consisting of a technical, industrial and business model generator. These generators are “parameter based”; they consist of a parameter-option matrix and design canvasses. Different variants for circular components can be synthesised by filling the canvasses through systematically “mixing and matching” design options.

Research limitations/implications

The developed tool does not yet support establishing causal links between “parameter-options” and identification of the most circular design variant.

Practical implications

The CBC-generator provides an important step to support the building industry in developing and implementing circular building components in the built environment.

Originality/value

Whilst existing tools and frameworks are not comprehensive, nor specifically developed for designing circular building components, the CBC-generator successfully supports the integral design of circular building components. First, it provides all the design parameters which should be considered; second, it provides extensive design options per parameter; and third, it supports systematic synthesis of design options to a cohesive and comprehensive circular design.

Abstract

Purpose

Numerous metals can be processed using the additive manufacturing process laser-based powder bed fusion of metals (PBF-LB/M, ISO/ASTM 52900). The main advantages of additive manufacturing technologies are the high degree of design freedom and the cost-effective implementation of lightweight structures. This could be profitable for gears with increased power density, combining reduced mass with considerable material strength. Current research on additively manufactured gears is focused on developing lightweight structures but is seldom accompanied by simulations and even less by mechanical testing. There has been very little research into the mechanical and material properties of additively manufactured gears. The purpose of this study is to investigate the behavior of lightweight structures in additively manufactured gears under static loads.

Design/methodology/approach

This research identifies the static load-carrying capacity of helical gears with different lightweight structures produced by PBF-LB/M with the case hardening steel 16MnCr5. A static gear loading test rig with a maximum torque at the pinion of T1 = 1200 Nm is used. Further focus is set on analyzing material properties such as the relative density, microstructure, hardness depth profile and chemical composition.

Findings

All additively manufactured gear variants show no failure or plastic deformation at the maximum test load. The shaft hub connection, the lightweight hub designs and the gearing itself are stable and intact regarding their form and function. The identified material characteristics are comparable to conventionally manufactured gears (wrought and machined), but also some particularities were observed.

Originality/value

This research demonstrates the mechanical strength of lightweight structures in gears. Future research needs to consider the dynamic load-carrying capacity of additively manufactured gears.

Abstract

Purpose

One of the greatest challenges faced by the 1994 post-apartheid government in South Africa is the housing problem that has persisted for almost 30 years into democracy. Innovation in research and practice is required to address this problem. This paper aims to discuss the aforementioned objective.

Design/methodology/approach

This paper presents an argument for housing knowledge management as one part of a much larger system of housing provision and critically compares information variations on one hypothetical, low-cost housing unit adapted for varying climatic regions. It aims to enquire if there is an overlap in information.

Findings

The findings do confirm a noteworthy overlap in the information of the varying units. Therefore, knowledge management of the information would prove effective and may contribute in part to housing provision.

Research limitations/implications

The study is limited to assessing the information changes made to the contract documentation of the housing unit.

Social implications

The paper argues that knowledge management of this overlapping information could impact housing provision by providing knowledge power to those affected by the housing problem.

Originality/value

The findings are a unique perspective presented through a knowledge management lens. In addition, the said knowledge management lens provides a platform to raise additional questions. When seeking answers to these questions, it is expected that research sub-themes would be identified focussing further research studies towards finding answers.

Abstract

Purpose

This paper aims to explore the intellectual structure shaping the circular economy (CE) discourse within the built environment in Africa.

Design/methodology/approach

The study adopted a bibliometric analysis approach to explore the intellectual structure of CE in the built environment in Africa. The authors collected 31 papers published between 2005 and 2021 from the Scopus database and used VOSviewer for data analysis.

Findings

The findings show that there are six clusters shaping the intellectual structure: demolition, material recovery and reuse; waste as a resource; cellulose and agro-based materials; resilience and low-carbon footprint; recycling materials; and the fourth industrial revolution. The two most cited scholars had three publications each, while the top journal was Resources, Conservation and Recycling. The dominant concepts included CE, sustainability, alternative materials, waste management, lifecycle, demolition and climate change. The study concludes that there is low CE research output in Africa, which implies that the concept is either novel or facing resistance.

Research limitations/implications

The data were drawn from one database, Scopus; hence, adoption of alternative databases such as Web of Science, Google Scholar and Dimensions could potentially have yielded a higher number of articles for analysis which potentially would result in different conclusions on the subject understudy.

Originality/value

This study made a significant contribution by articulating the CE intellectual structure in the built environment, identified prominent scholars and academic platforms responsible for promoting circularity in Africa.

Abstract

Purpose

In total, 19 practices of circular economy divided into three groups, internal environmental management, ecological design and investment recovery were studied in a local network composed of small companies and individual entrepreneurs related to common product and by-product flows. The paper aims to discuss these issues.

Design/methodology/approach

This research presents an applied nature, is characterized as exploratory and adopted the case study as a technical procedure using sources and methods of data collection. The primary data were collected through direct observation of the processes and semi-structured interviews with managers and owners.

Findings

The most widespread practices are related to product design. However, in most cases, the implementation was punctual and did not present continuous and corresponding actions, which highlights the embryonic contours of European Commission (EC) in the observed network. The practices from the management category were less observed, which revels the environmental variable is not included in the strategic business planning.

Research limitations/implications

The research documents the application of CE practices in a local network and brings this current paradigm shift to the Brazilian context.

Practical implications

To overcome barriers to the implementation of EC practices, it is suggested to restructure commercial relations, to formulate public policies and to develop infrastructures that facilitate the materiality of flows and the market.

Social implications

The study highlights the need of public policies that promotes cross-sectoral cooperation in accordance with NSWP objectives.

Originality/value

Despite the focus on EC implemented practices this study offers a framework of the research routes on the main barriers and suggests actions to overcome the challenges in the transition from the economy to the circular model.

Abstract

Purpose

The purpose of this paper is to progress operations management theory and practice by organising contributions to knowledge production, in industrial sustainability, from disparate researcher communities. It addresses the principal question “What scholarly dialogues can be explicated in the emerging research field of industrial sustainability?” and sub-questions: what are the descriptive characteristics of the evidence base? and what thematic lines of scientific inquiry underpin the body of knowledge?

Design/methodology/approach

Using an evidenced-based approach, a systematic review (SR) of 574 articles from 62 peer-reviewed scientific journals associated with industrial sustainability is conducted.

Findings

This paper distinguishes three prevailing dialogues in the field of industrial sustainability, and uses Kuhn’s theory of paradigms to propose its pre-paradigmatic scientific status. The three dialogues: “productivity and innovation”, “corporate citizenship” and “economic resilience” are conjectured to privilege efficiency strategies as a mode of incremental reductionism. Industrial sustainability espouses the grand vision of a generative, restorative and net positive economy, and calls for a future research trajectory to address institutional and systemic issues regarding scaling-up and transition, through transformative strategies.

Research limitations/implications

The review is limited by the nature of the inquiries addressed in the literatures by specific researcher communities between 1992 and 2014.

Originality/value

This study performs the first SR in the field of industrial sustainability, synthesises prevailing scholarly dialogues and provides an evaluation of the scientific status of the field.

Abstract

Climate change is occurring around us and impacting on our daily lives, meaning that we have to deal with our cities in a different way. There is also increasing awareness of the need for daily contact with green spaces and the natural environment in order to live a happy, productive and meaningful life.

This reflective essay tells the narrative of how urbanisation has been disconnecting humans from nature. Non-sustainable, non-resilient patterns of urbanisation, along with the neglect of inner-city areas, have resulted in fragmentation and urban decline, led to a loss of biodiversity, and caused the deterioration of ecosystems and their services. Urban regeneration projects allow us to “repair” and restore some of this damage whilst enhancing urban resilience. Connecting existing and enhanced ecosystems, and re-establishing ecosystems both within cities and at the peri-urban fringe is vital for strengthening ecosystem resilience and building adaptive capacity for coping with the effects of climate change.

Cities worldwide need to look for suitable solutions to increase the resilience of their urban spaces in the face of climate change. This essay explores how this can be achieved through the integration of nature-based solutions, the re-greening of neighbourhoods and by correctly attributing value to natural capital. Transforming existing cities and neighbourhoods in this way will enable ecosystems to contribute their services towards healthier and more liveable cities.

Abstract

Purpose

This paper aims to enhance the impact of incorporated waqf institutions by blending their resources to promote responsible small businesses that are inclusive of human development, service to society and preservation of ecological environment and other species. This is expected to shift the paradigm of businesses from the current waste-oriented linear economy to ideally a zero-waste circular economy.

Design/methodology/approach

This is an analytical study building on the experience of European Venture Philanthropy Organizations (VPOs) that work with the primary objective of making impactful businesses successful, with capital protection and return on investment being of secondary concern. This paper suggests an incorporated institutional design that blends resources for promoting responsible businesses using a new hybrid financial mechanism, namely, equity-at-default (EaD) to replace collateral and foreclosure requirements with responsibility and compassion.

Findings

The research calls for changing the business paradigm from linear to circular, an incorporated institutional framework for venture waqf, purpose of the waqf to make impactful small businesses successful and designing a financial contract to loan in favor of responsible businesses that convert to equity stake for the waqf in case of default (EaD) replacing collateral and foreclosure requirements.

Research limitations/implications

This is a theoretical study motivated by the success of VPOs but assigns a new role to waqf institutions. Furthermore, the incorporated nature of waqf is a new idea and EaD is a new mechanism. Being new, these ideas have the risk of not being implemented. However, the broader message that waqf shall promote businesses that are inclusive of ecological concerns is generally applicable.

Practical implications

The paper has a significant practical implication to transform the responsibility and consciousness of businesses. Waqf is fundamentally a compassionate institution, and it must enhance the responsibility of businesses to become more inclusive of the environment and other species. It should also become more compassionate toward businesses that are in distress and default. In this sense, the paper tries to internalize compassion in financial contracting that can potentially change the architecture of lending.

Social implications

Altering businesses’ mindset from a waste-driven extractive linear economy to inclusive circular economy has a tremendous transformative role. This will have implications for enhancing business consciousness and responsibility. As poverty is a phenomenon of state of mind, changing the society’s state of thought in Muslim communities is expected to have basic positive implications. Entrepreneurs with a new mindset can have far-reaching positive impacts on the society.

Originality/value

The paper offers potentially innovative perspectives in four key areas and blends the different resources in an incorporated waqf that makes responsible entrepreneurs assume a partnership role in times of distress through EaD. Furthermore, the integration of compassion in financial contracting could have better implications for return on investment as well. The ideal state of an economy is where waste is turned into wealth and well-being is something that all policymakers must keep on the top of their agendas.
