How COVID-19 redefines the concept of sustainability

Abstract: In January 2020, the World Health Organization (WHO) declared the outbreak of a new coronavirus disease, COVID-19, to be a public health emergency of international concern. Currently, in several countries globally, this pandemic continues to enforce the temporary closure of all nonessential shops and services aside from supermarkets and pharmacies. Workers in countries that are at a high risk of infection have been asked to work from home, as cities have been placed under lockdown. Even curfews to combat the spread of the virus have been imposed in several countries, with all this signaling an unprecedented disruption of commerce. Companies are facing various challenges regarding health and safety, supply chain, labor force, cash flow, consumer demand and marketing. People in the thousands are dying every day from the virus’s symptoms, while a public health issue has forced the world to come to a halt and rethink what a sustainable future for our planet and existence is. These drastic recent events have raised the deliberation by the authors to redefine the concept of sustainability.

Sustainability Benefits of RFID Technology in the Apparel Industry

Abstract: Digitalization and big data are currently moving many industries forward and creating value-added efficiency improvements, new services, and business models. One area in industrial digitalization is RFID (Radio Frequency Identification) and related sensor technologies with benefits in asset visibility, employee productivity, risk management, loss, and theft mitigation. This literature review article is focused on specifically looking at digitalization in the apparel industry. Due to its complex global network, it has been a challenging industry to implement such technological advancements. Recent novel RFID system integrations have included highly innovative solutions in new store concepts, business models, and product traceability in the value chain. Inventory management has been improved by using RFID technology for creating and updating and for more efficient controls. Also, chain of custody of the various products in apparel and fashion can be more traceable and efficient. Improved customer connectivity and, therefore, customization are also important benefits using these technologies. Most benefits in using RFID in the apparel industry are related to economics and efficiencies. Similarly looking at scientific literature, the majority is focused on the more business-related value creation. In this publication, results of a systematically made literature review focusing on the three dimensions of sustainability (environmental, social, and economic systems) is reported. This review is done using value chain analyses, and it focuses on reported case studies to highlight the sustainability benefits of the RFID technology. According to the literature findings, this is the first review article that reports on the broader sustainability impact of RFID in the apparel industry. The findings show a very limited number of articles and the main focus of the articles found was in environmental aspects (44%). Following that was economic benefits (36%), and only a limited amount of research articles was found in social aspects of sustainability (20%). In addition to identifying the sustainability areas that RFID technology is related to, this article shows other areas of improvements using RFID technology in different parts of the apparel value chain.

Remarkable Physical and Thermal Properties of Hydrothermal Carbonized Nanoscale Cellulose Observed from Citric Acid Catalysis and Acetone Rinsing

Abstract: Citric acid (CA) was used for the hydrothermal carbonization (HTC) of cellulose nanofiber and found to exert remarkable effects on the chemistry and physical aspects of the product distribution. More specifically, the morphology, yield, elemental and proximate composition, chemical functional groups, thermal properties and surface properties of the resultant hydrochars were studied extensively. The morphological properties of the final char were the singularly most surprising and unique finding of this study. The cellulose nanofiber hydrochars were contrasted to hydrochars from bleached softwood pulp, having a similar composition with the former, to pinpoint the role of nano-dimensions. Without the presence of CA, the pulp hydrochar lacked several of the spherical dimensions shown in the nanocellulose; however, and unexpectedly, the presence of CA caused a homogenization of the final product distribution for both samples. Finally, thermally stable and high surface area hydrochars were obtained when the hydrochar was rinsed with acetone.

Removal of Water and Extractives from Softwood with Supercritical Carbon Dioxide

Abstract: Supercritical CO2 (sCO2) removes both water and extractives from wood chips and flakes at 60 °C. The water appears to be mostly displaced by sCO2 because its nominal concentration in sCO2 exceeds its solubility limit. SEM imaging and contact angle measurements show no major differences in surface properties between sCO2-treated and thermally dried flakes, which suggests that their interaction with resin should be similar. An economic analysis for the removal of water and extractives from pine flakes for the manufacture of oriented strand board shows that sCO2 treatment is potentially much more cost-effective than thermal drying from both capital and operational perspectives. The main reasons are that the water is removed by displacement rather than through evaporation, environmental control costs are drastically reduced, and the extractives removed represent a value stream instead of pollutants whose emissions need to be controlled. Because the sCO2 is largely recirculated, the process is greener than con...

COVID-19 pandemic related supply chain studies: a systematic review

Abstract: The global spread of the novel coronavirus, also known as the COVID-19 pandemic, has had a devastating impact on supply chains. Since the pandemic started, scholars have been researching and publishing their studies on the various supply-chain-related issues raised by COVID-19. However, while the number of articles on this subject has been steadily increasing, due to the absence of any systematic literature reviews, it remains unclear what aspects of this disruption have already been studied and what aspects still need to be investigated. The present study systematically reviews existing research on the COVID-19 pandemic in supply chain disciplines. Through a rigorous and systematic search, we identify 74 relevant articles published on or before 28 September 2020. The synthesis of the findings reveals that four broad themes recur in the published work: namely, impacts of the COVID-19 pandemic, resilience strategies for managing impacts and recovery, the role of technology in implementing resilience strategies, and supply chain sustainability in the light of the pandemic. Alongside the synthesis of the findings, this study describes the methodologies, context, and theories used in each piece of research. Our analysis reveals that there is a lack of empirically designed and theoretically grounded studies in this area; hence, the generalizability of the findings, thus far, is limited. Moreover, the analysis reveals that most studies have focused on supply chains for high-demand essential goods and healthcare products, while low-demand items and SMEs have been largely ignored. We also review the literature on prior epidemic outbreaks and other disruptions in supply chain disciplines. By considering the findings of these articles alongside research on the COVID-19 pandemic, this study offers research questions and directions for further investigation. These directions can guide scholars in designing and conducting impactful research in the field.

The Post Pandemic City: Challenges and Opportunities for a Non-Motorized Urban Environment. An Overview of Italian Cases

Abstract: COVID-19 has forced city governments to reconsider the relationship between mobility, urban space and health in order to ensure physical distancing while meeting the travel needs of inhabitants. Therefore, cities around the world are already involved in the transformation of mobility through new models of sustainable transport. The World Health Organization (WHO) guidelines on mobility during the COVID outbreak are mostly directed at creating more spaces for cyclists and pedestrians, especially in densely populated urban areas, thus avoiding the overloading of public transport and the use of private cars. Through the analysis of the programs set up by the 10 main Italian metropolitan cities, chosen as a case study, this research evaluates the response implemented by local governments in order to transform urban environments in one of the world’s most pandemic-affected countries in detail. Starting from the current mobility model, this paper focuses on local government policies concerning post-COVID sustainable mobility to understand policies, approaches and measures in depth, as well as the effectiveness of the ongoing actions in shaping future urban mobility. From the research, an almost homogeneous awareness among policy makers and planners emerges concerning the need to rethink urban spaces and mobility, to make up for lost time and to start a green revolution that is aimed at quickly decarbonizing urban transport and enhancing cycling and walking through the city.

Thriving, Not Just Surviving in Changing Times: How Sustainability, Agility and Digitalization Intertwine with Organizational Resilience

Abstract: Nowadays, the buzzwords for organizations to be prepared for the competitive environment’s challenges are sustainability, digitalization, resilience and agility. However, despite the fact that these concepts have come into common use at the level of both scholars and practitioners, the nature of the relation between sustainability and resilience has not yet been sufficiently clarified. Above all, there is still no evidence of what factors determine greater resilience to change in an organization that also wants to be more sustainable, especially in times of crisis and discontinuity. This research aims to explore from a theoretical point of view, through the construction of a conceptual model, how these dimensions interact to help the business to become strategically resilient by leveraging digitization and agility as enablers. A new view of resilience arises from the study, which goes beyond the well-known ability to absorb or adapt to adversity, to also include a strategic attribute that could help companies capture change-related opportunities to design new ways of doing business under stress. A key set of strategically agile processes, enabled by digitalization, creates strategic resilience that also includes a proactive, opportunity-focused attitude in the face of change. Strategic resilience to lead to organizational sustainability must be understood as a multi-domain concept quite similar to the holistic view of sustainability: environment, economy and society. Finally, the research offers a set of propositions and a theoretical framework that can be empirically validated.
