Social life-cycle assessment: A review by bibliometric analysis

This study examined the literature on social life-cycle assessment (S-LCA) published in the last 15 years (2003–2018) using bibliometric methods. Applying scientific mapping and analyzing publication performance, the study describes the structure of and trends in S-LCA publications in terms of related subject categories, authors, journals, countries, and highly cited articles. Challenges and research gaps in the S-LCA literature were also explored. The content of related papers published in the ISIWeb of Science databases was examined to identify the main themes investigated, evolution of publication activity, and most representative elements. Analyses were conducted with SciMAT software. This tool enables researchers to map research specialties by extracting qualitative information in the specialized literature and representing it using quantitative measures. The results show rapid and exponential growth of the S-LCA research line in the past ten years, with a clear upward trend in related publications (mostly case studies), especially after publication of the UNEP/SETAC Guidelines for Social Life Cycle Assessment of Products in 2009: 66% of all articles published on S-LCA were published during the period 2015–2018, primarily by European authors. The findings also delineate S-LCA as a highly fragmented research field that has been applied to diverse sectors (agriculture, bioenergy, transport, water management, chemical products, electronics, etc.), mainly in non-European countries. Critical questions concerning methods, framework, paradigms, and indicators remain to be resolved. This study provides insight into the publication performance of S-LCA, characterizing its intellectual structure and salient authors and works. In identifying hotspots in the S-LCA research, the study provides a useful state-of-the-art reference guide for academics and reveals critical research gaps and potential research avenues for future studies to advance in consolidating the discipline.This study examined the literature on social life-cycle assessment (S-LCA) published in the last 15 years (2003-2018) using bibliometric methods.

Sustainability transition in industry 4.0 and smart manufacturing with the triple-layered business model canvas

Sustainability transition is becoming increasingly relevant at a manufacturing level, especially for resource- and energy-intensive industries. In addition, the 4.0 industry paradigm opens new opportunities in terms of sustainable development. The aim of this research is to analyze the introduction of sustainability in the corporate value proposition, through the evolution from a traditional to a sustainable business model. The business model innovation will be investigated in the case of a ceramic tile producer in the district of Sassuolo, Italy. The company has introduced several sustainability practices over the years and, through investments in Industry 4.0 technologies, is able to conduct impact assessments of its production process. The applied tool for the business model transition will be the Triple-Layered Business Model Canvas by Joyce and Paquin. The results illustrate the new company's sustainable value proposition, considering all three pillars of sustainability: environment, economy, and society. Despite the limitations resulting from the individual case study, the findings can be easily adapted to other ceramic tile companies in the sector. Besides, the paper could inspire other manufacturing companies in the drafting of a sustainable business model. The paper explores the still limited literature on the application of sustainable business models in operational scenarios

Industry 4.0 real-world testing of dynamic organizational life cycle assessment (O-LCA) of a ceramic tile manufacturer

In manufacturing, Industry 4.0 operating models enable greener technologies. Thanks to digital technologies, environmental sustainability and organizational competitiveness are mutually reinforcing. The challenge for manufacturing organizations is to understand and quantify the magnitude of this synergistic action, and the holistic perspective of life cycle assessment tools may be a solution to the problem. Organizational Life Cycle Assessment (O-LCA) unlike Product Life Cycle Assessment (LCA) is still an under-researched methodology with few applications in manufacturing contexts. This paper aims to fill this gap by implementing and validating O-LCA in the case of an Italian ceramic tile manufacturer. Following the O-LCA guidelines and exploiting Industry 4.0 technologies to perform the inventory analysis, the environmental assessment was conducted in three different plants, comparing the sum of the partial impact results with the overall results scaled to the whole organization. The experimental results demonstrated the validity of the organizational approach as an appropriate methodological option to obtain relevant information on environmental performance that, being based on empirical evidence, better support decision-making processes. Furthermore, the study provides empirical evidence of how Industry 4.0 is an enabler not only for the adoption of greener technologies, but especially for facilitating the organizational environmental impact assessment that is the necessary condition in order to set up and maintain greener manufacturing contexts

Main dimensions in the building of the circular supply chain: A literature review

Circular economy is an alternative to the traditional production model and has therefore attracted a great deal of attention fromresearchers. The change in the production system is accompanied by new logistical needs related both to resources and waste and to the distribution and recovery of products. The circular supply chain involves return processes and the manufacturer intends to capture additional value in the supply chain. In this paper, value chains have been mapped to visualize the links and interactions between the different stages and actors to understand the complexities of these systems and to make informed decisions. For this reason, and based on thorough literature review, the final objective of this work is to achieve a conceptual framework to study circular supply chain, which uses the main theoretical perspectives in strategic management literature. Four dimensions have been identified to support the development of these new supply chains-greater intensity in the relationships established in the supply chain, adaptation of logistics and organizational, disruptive and smart technologies, and a functioning environment. It can be concluded that to develop a new relationship capacity will allow for reaching more frequent, closer relationships with more actors. These relationships will be developed within an adapted organizational and logistical framework that is framed in new business model archetypes. However, dimensions related to the business environment such as sectoral, legislative, and fiscal frameworks must be incorporated

Social Organizational Life Cycle Assessment (SO-LCA) and Organization 4.0: An easy-to-implement method

Organizations often face difficulties when measuring their social performance. The lack of international standards, the qualitative/quantitative nature of data, and the unavailability of primary sources all hinder social impact assessments, especially in manufacturing settings. To fill these gaps, the method proposes a simple application protocol of Social Organizational Life Cycle Assessment (SO-LCA), customized for an Italian ceramic tile manufacturer. The method leverages Industry 4.0 digital technologies to collect real-time primary and site-specific social data, making the social assessment dynamic. The managerial approach adopted for the selection of social metrics and weighting of indicators and indexes, can support the transition of the manufacturing organization into Organization 4.0. The method also provides a contribution to the operational validation of the UNEP guidelines by extending their area of application. Finally, the proposed method gives substance to social responsibility through social accounting, helping the organization to measure the correct social impact starting from the detailed data, namely the decisions made in the business and in production. • Social Organizational Life Cycle Assessment (SO-LCA) application protocol validated in Industry 4.0 environment. • Social metrics directly linked to production and business processes for the dynamic assessment of social performance. • Easy replicability of the method in other organizational contexts

Identification and rejection of pile-up jets at high pseudorapidity with the ATLAS detector

The rejection of forward jets originating from additional proton–proton interactions (pile-up) is crucial for a variety of physics analyses at the LHC, including Standard Model measurements and searches for physics beyond the Standard Model. The identification of such jets is challenging due to the lack of track and vertex information in the pseudorapidity range |η| > 2.5. This paper presents a novel strategy for forward pile-up jet tagging that exploits jet shapes and topological jet correlations in pile-up interactions. Measurements of the per-jet tagging efficiency are presented using a data set of 3.2 fb−1 of proton–proton collisions at a centre-of-mass energy of 13 TeV collected with the ATLAS detector. The fraction of pile-up jets rejected in the range 2.5 < |η| < 4.5 is estimated in simulated events with an average of 22 interactions per bunch-crossing. It increases with jet transverse momentum and, for jets with transverse momentum between 20 and 50 GeV, it ranges between 49% and 67% with an efficiency of 85% for selecting hard-scatter jets. A case study is performed in Higgs boson production via the vector-boson fusion process, showing that these techniques mitigate the background growth due to additional proton–proton interactions, thus enhancing the reach for such signatures

Does religion influence location choice in the hotel industry?

Relying on data from the Spanish hotel industry, this paper analyzes the role of informal institutional factors (IIF) in location choice. Earlier studies mostly use an aggregate level of cultural differences as informal institutional factors. We, however, go deeper into this concept and study the impact of two distinct but interrelated informal institutional factors, religion and language, on the location decisions of hotel chains. We resolve the overlapping problem between these two highly correlated IIF by means of a ‘layer’ measurement in Confirmatory Factor Analysis. Our results show that the higher the informal institutional differences (IID), the lower the presence of the hotels in the foreign country. While physical distance plays a key moderating role, formal institutional differences (FID) did not show any effect. We contribute by unravelling the role of language and religion in location choice in the internationalization process of service firms. Moreover, we test the moderating role of formal institutions in these decisions, thus combining the impact of formal and informal institutions on location choices in service firms

New circular networks in resilient supply chains: An external capital perspective

The pandemic caused by COVID-19 has had an impact on the relationships established between different actors in organisations. To deal with these changes, it is necessary to develop a resilience capacity that allows for the establishment of different patterns of relationships through a new management model. The application of circularity principles implies a radical change in stakeholder relations, breaking with the “end-of-life” concept existing in linear economies. Fur-thermore, circular economy can ensure resilience in supply chains, and it can be considered as a tool in uncertain environments. Therefore, the objective of this study is to analyse the association between the customer–supplier relationships with circular supply chains based on the intellectual capital-based view theory. External capital is a crucial factor for organisations, and it helps with building remarkable capabilities for the whole supply chain due to collaboration and cooperation. This research contributes with a systematic revision of the literature regarding circular supply chains and customer–supplier external capital, providing an exploratory model. Establishing a closer and effective relationship with customers and suppliers supposes a differentiating value and competitive advantages. Actors involved in the supply chain are essential in the implementation of circularity in organisations for reducing waste production and returning resources to the production cycle. Therefore, circular networks related to customers’ behaviour, sustainable supplier election and IT tools play a key factor in improving resilience in supply chains

Analysis of the Textile Supply Chain from a Circularity Perspective: A Case Study

Circular economy practices and its implementation is paramount to drive the design of circular and reverse supply chains, thus enabling products to enter the chain again through recycling and reuse. The main purpose of the research is to analyze the importance of the supply chain in the transition to a circular economy, focusing on the textile industry. So-called “fast fashion” and the linear supply chains followed by the large fashion multinationals are a serious problem. The textile closed supply chain and its harmful effects have been examined, as well as the boosters and barriers associated with their transformation under the circularity paradigm. The implementation of circularity in this industry implies a systemic rethinking of the entire supply chain. A case study of “Teemill” company which produces and sells circular T-shirts is analyzed. The main results showed that Circular Supply Chains in the textile sector are based on two fundamental pillars for their development. On the one hand, the development of new technology that reduces waste and increases efficiency in productivity, using renewable energy and circular principles in all phases of their supply chain through reverse logistics. On the other hand, based on this technological development, the establishment of long-term agreements that allow developed a cloud-connected supply chain. Coordination and cooperation between suppliers and manufacturers are essential to achieve more sustainable products. In addition, customers play a key role in their participation in the recycling and recovery of products

Dynamic life cycle assessment (LCA) integrating life cycle inventory (LCI) and Enterprise resource planning (ERP) in an industry 4.0 environment

With the advent of Industry 4.0, new technologies have been made available to companies in order to monitor, integrate and trace processes through integrated digital systems; thanks to a combination of sensors and control systems, manufacturing information are collected and processed so that a detailed database helpful for the monitoring and continuous improvement of the production plant can be built. The potentiality of this comprehensive data collection may be exploited also from an environmental point of view, with the aim to enhance the sustainability of processes; in fact, a large part of this data provides the basis for the Life Cycle Inventory (LCI), the most energy and time-consuming phase of the Life Cycle Assessment (LCA) which in this way could become quicker and dynamic. Based on a case study related to an Italian ceramic tile manufacturer, the aim of this paper is to describe the architecture and the application of the Dynamic LCA system that integrates the Enterprise Resource Planning (ERP) system with a customized LCA tool through a Business Intelligence (BI) software. The model was tested on different levels of validation in order to verify first the proper functioning of the IT architecture and then the environmental impact results provided, both in a static and dynamic way. The validation processes were successful, and the Dynamic LCA system has proved to be a valuable tool for the evaluation and monitoring of environmental impacts related to the production process
