Magnesium is a promising material. It has a remarkable mix of mechanical and biomedical properties that has made it suitable for a vast range of applications. Moreover, with alloying, many of these inherent properties can be further improved. Today, it is primarily used in the automotive, aerospace, and medical industries. However, magnesium has its own set of drawbacks that the industry and research communities are actively addressing. Magnesium’s rapid corrosion is its most significant drawback, and it dramatically impeded magnesium’s growth and expansion into other applications. This article reviews both the engineering and biomedical aspects and applications for magnesium and its alloys. It will also elaborate on the challenges that the material faces and how they can be overcome and discuss its outlook.

Advancing societal’s progress to achieve circularity is imperative as our linear (take, make, waste) economic model is highly unsustainable. It depletes our natural resources and substantially contributes to pollution and global greenhouse gas emissions. Our continued participation in the linear economy will also expose businesses to volatile resource prices and supply disruptions resulting from the scarcity of critical materials and geopolitical factors. Hence, there are compelling reasons for businesses to transit and participate in the circular economy. However, anecdotal evidence suggests limited practical implementations. Therefore, this systematic review aims to determine the most significant drivers and barriers that influence business leaders to transform their businesses for participation in the circular economy. By clarifying the most influential factors and their characteristics, we can introduce effective measures to encourage or mitigate them. This review takes a transdisciplinary approach to discuss salient and consequential ideas with depth and completeness. Its associated practical and managerial implications are also thoroughly discussed.

More than 78 million tons of photovoltaic modules (PVMs) will reach their end of life (EOL) by 2050. If they are not responsibly managed, they can (a) pollute our terrestrial ecosystem, (b) indirectly encourage continuous mining and extraction of Earth’s finite resources, and (c) diminish the net environmental benefit of harvesting solar energy. Conversely, successfully recovering them could reduce resource extraction and waste and generate sufficient economic return and value to finance the production of another 2 billion PVMs by 2050. Therefore, EOL PVMs must participate in the circular economy, and business and political leaders are actively devising strategies to enable their participation. This article aims to facilitate and expedite their efforts by comprehensively reviewing and presenting the latest progress and developments in EOL PVM recovery methods and processes. It also identifies and thoroughly discusses several interrelated observations that impede or accelerate their efforts. Overall, our approach to this article differs but synergistically complements and builds upon existing life cycle assessment-based (LCA-based) contributions.

Achieving plastic circularity is imperative to using plastics without adverse effects. Today, only 9% of global plastic waste is recycled, signifying the need for more substantial advancements to accelerate our progress toward achieving plastic circularity. This article contributes to our collective efforts to accelerate plastic circularity by critically assessing the state-of-the-art, gaps, and outlook of the pathways and processes to circular plastics. It employs qualitative methods to derive new insights that empower scholars and practitioners to prescribe effective strategies to shape the future of plastic circularity and its research agenda. This article concludes that today’s circularity pathways for plastics are not economically viable, significantly hindering their scalability and widespread adoption. It further validates that focusing on the product design and effectiveness of the available collection and sorting systems can considerably improve our progress in achieving plastic circularity.
