22. Manufacturing sustainability: Institutional theory and life cycle thinking

Author

Ebrahimi, S.M. and Koh, L.

Abstract

This study sets out to bridge resource perspective on material selection with stakeholder and institutional theory considerations to provide a more comprehensive understanding of life-cycle thinking on material selection decisions in the automotive industry. The objective is to shed light on how regulatory, normative and mimetic institutional pressures, affect sustainability decisions when switching or substituting materials or manufacturing processes in the automotive industry. Within a hybrid life cycle analysis framework, the environmental hotspots across the supply chains of two empirical management examples of Aluminium and CFRP LCA models are presented, quantified and ranked. Further justifications are provided on why and how regulatory, normative-peer and peer-normative pressures affect life cycle decisions. Findings reveal early, mid-process and late-stage life cycle hotspots, both in the material selection and the manufacturing process for both components. This decision support framework can be used to diverge from high energy-intensive manufacturing process and conventional raw materials, and provide forward-looking automotive manufacturers with opportunity to make asset-specific investments in lightweight, fuel-efficient vehicles, and sustainable manufacturing operations. This study presents a new framework that hybridises institutional theory and life cycle thinking to enable a standard routine and decision assessment of sustainability. This study provides a novel theoretical perspective on life cycle assessment by highlighting how the framing rules in a given institution mirror the trajectory of institutional pressures from regulatory (organised laws) through normative (organised behaviour) to mimetic (copied behaviour).

Abstract

The World Health Organization declared COVID-19 a global pandemic on the 11th of March, 2020, but the world is still reeling from its aftermath. Originating from China, cases quickly spread across the globe, prompting the implementation of stringent measures by world governments in efforts to isolate cases and limit the transmission rate of the virus. These measures have however shattered the core sustaining pillars of the modern world economies as global trade and cooperation succumbed to nationalist focus and competition for scarce supplies. Against this backdrop, this paper presents a critical review of the catalogue of negative and positive impacts of the pandemic and proffers perspectives on how it can be leveraged to steer towards a better, more resilient low-carbon economy. The paper diagnosed the danger of relying on pandemic-driven benefits to achieving sustainable development goals and emphasizes a need for a decisive, fundamental structural change to the dynamics of how we live. It argues for a rethink of the present global economic growth model, shaped by a linear economy system and sustained by profiteering and energy-gulping manufacturing processes, in favour of a more sustainable model recalibrated on circular economy (CE) framework. Building on evidence in support of CE as a vehicle for balancing the complex equation of accomplishing profit with minimal environmental harms, the paper outlines concrete sector-specific recommendations on CE-related solutions as a catalyst for the global economic growth and development in a resilient post-COVID-19 world.

26. The role of resource efficiency for achieving climate neutrality [Webinar]

Author

Institute of Materials, Minerals & Mining, Koh L., Institute of Materials, Minerals & Mining, and Koh L.

Abstract

In this technical lecture and question and answer session, Professor Lenny Koh discussed her research that intersects supply chain and information sciences for resource efficiency and sustainability. Resource efficiency and circular economy are key enablers for achieving climate and carbon neutrality towards net zero. Amongst the various energy technologies and vectors such as CCUS, nuclear, hydrogen, zero carbon and biomass-fuel, renewable sources such as wind and PV, and energy storage and batteries which will play a key role; the supply chains and systems must be resource efficient and sustainable. This talk focused on demonstrators and examples of how these can be achieved at various scale and the importance of circularity and resource efficiency in such a pathway, including nature based solutions and energy technologies that can decarbonise cities/nations, industries and transports through materials supply chain environmental assessment innovation., In this technical lecture and question and answer session, Professor Lenny Koh discussed her research that intersects supply chain and information sciences for resource efficiency and sustainability.

49. Life cycle assessment of functional materials and devices : opportunities, challenges, and current and future trends

Author

Smith, L., Ibn‐Mohammed, T., Koh, L., and Reaney, I.M.

Abstract

Functional ceramics such as piezoelectrics, thermoelectrics, magnetic materials, ionic conductors, and semiconductors are opening new frontiers that underpin numerous aspects of modern life. This widespread usage comes with a responsibility to understand what impact their mass production has on the environment. Life‐cycle assessment (LCA) is a tool employed for the identification of sustainable materials pathways through the consideration of environmental burdens of materials both during fabrication and as a final product. Although the LCA technique has been widely used for the evaluation of environmental impacts in numerous product supply chains, its application for environmental profiling of functional ceramics is now gaining attention. This paper presents a review of current developments in LCA, including existing and emerging applications with emphasis on the development and fabrication of functional materials and devices (FM&D). Selected published works on LCA of functional ceramics are discussed, highlighting the importance of adopting LCA at the design stage and/or at laboratory stage before expensive investments and resources are committed. Drawing from the extant literature, we show that the integration of environmental and sustainability principles into the overall process of FM&D manufacturing, in a way that anticipates foreseeable harmful consequences while identifying opportunities for improvement, can aid the timely communications of key findings to functional materials developers. This guides the orientation of research, development and deployment, and provides insights toward the prioritization of research activities while potentially averting unintended consequences. It is intended that the review presented will encourage the materials science community to engage with LCA to address important materials design, substitution, and optimization needs.
