Abstract Under new “make in India policy” India has started to become global manufacturing hub and many Indian organizations are looking to implement lean philosophy to gain sustainable strategic benefits over others. Therefore, a need was felt to develop comprehensive lean evaluation system for Indian automotive small & medium sized enterprises in order to measure its present lean status and potential improvements to gain significant strategic advantages. Research started with the identification of various lean factors and associated sub factors through literature survey. Fuzzy analytic hierarchy process was applied to assign weight to various extracted lean factors and sub factors because of its evident merits. Fuzzy comprehensive analysis was applied to assess present status of Indian automotive small and medium sized enterprises, where lean does not practice. Lean performance of Indian automotive small & medium sized enterprises was ascertained as poor. The proposed model could be useful to guiding the Indian automotive small and medium sized enterprises in judicial selection of lean practices to gain significant sustainable strategic advantage over its competitors. Novelty of this research is to emerge from the development of comprehensive lean measurement model for Indian small and medium sized enterprises in automotive sector.

Sustainability is a key area of concern for manufacturing firms’ long-term success. However, the manufacturing industry has not been fully conscious of the potential sustainable values across manufacturing system. There is a need to better understand how companies can improve sustainable value creation. Recent research and practices have shown that sustainable operations can be one way to create sustainable values (e.g. economic, environmental and social). This review article focuses on the available empirical studies on the impact of lean and sustainability practices on sustainable performance from 2000 to 2018 in the context of manufacturing firms. Integrating lean and sustainability practices into manufacturing system confrontы operations managers with paradoxical tensions of sustainability objectives. Theoretically having paradoxical mindset will help firms’ managers make sense of and responв to such paradoxical tensions. In the context of sustainable operations studies, the issue of paradoxical mindset has been given less emphasis. Therefore, through the lens of the paradox theory, this study has developed a new conceptual framework for future research to investigate how paradoxical mindset moderates the impact of lean and sustainability practices on the sustainable performance of manufacturing industry. This study may add to the understanding of the circumstances, under which lean and sustainability practices impact sustainable outcomes.

Full textAbstract:
In this paper we investigate the elaboration of an efficient production schedule for sustainable manufacturing systems. Because renewable energies are irregular by nature as they often depend on meteorological conditions (e.g. wind and solar energy), their use in the competitive field of manufacturing production must be addressed with caution. The challenge is to elaborate a reliable production schedule that accommodates energy stochastic fluctuations while satisfying customer and operational constraints. We propose to solve the problem using a meta-heuristic based on Tabu search and discuss major elements that are critical to the success of this approach.

Abstract The sustainable development concept has become an extraordinarily important formative element of all activities taken by both law makers and the society, including entrepreneurs, for favour of broadly comprehended natural environment protection. This article presents the analysis of practical implementation of the sustainable development concept in manufacturing companies in Poland in the years 2010-2012. It also verifies directions of expenditures made towards environmental protection fixed assets, depending upon investment types, i.e. whether they were end-of-pipe investments or integrated technology investments. It was found that in the industrial processing sector in Poland, the highest average share of expenditures was associated with air and water protection fixed assets, whereas, in case of amounts spent on air protection means, a fall was observed in their share, and an increase in case of water protection. Furthermore, end-of-pipe investments dominated within the structure, whereas an increase was observed in the share end-of-pipe investments, and a fall in the share of integrated technology investments. It was also found that total amounts spent on environmental protection fixed assets per one company and per one employee increased, and the share of this type of expenditures in the total value of fixed assets obtained from manufacturing companies’ investment activities increased as well.

Research highlights the increasing engagement of SMEs in adopting sustainable practices to enhance their sustainable performance. This paper extends the current literature on sustainable manufacturing practices (SMPs) and SMEs’ sustainable performance by examining the mediating effect of competitive capabilities and the moderating impact of environmental regulation. Structured questionnaires were used to collect data from 288 manufacturing SMEs in China. Research findings using structural equation modeling with partial least squares (PLS-SEM) revealed that adopting SMPs enables SMEs to gain competitive capabilities and to positively influence their sustainable performance. In addition, gaining competitive capabilities have a positive mediating impact on the relationship between SMPs and SMEs’ sustainable performance. Further, the interaction between SMPs and environmental regulation strengthens SMEs’ sustainable performance. At the end of this paper, a set of concluding remarks and implications is drawn.

European union end of life vehicle directive mandates the use of more sustainable/recyclable materials in automotive industries. Thermoplastics matrix-based composites allow recyclability of composites at the end of life; however, their processing technology is more challenging than thermoset composites. Manufacturing process and mechanical testing of sustainable sandwich composite made from sustainable materials: flax, recycled carbon fiber, polypropylene, and recycled PET foam are presented in this article. High pressure compression molding with adhesive thermoplastic polymer film was used for manufacturing sandwich composite skin. The recycled PET foam core was integrated/joined with the skin using a thermoplastics adhesive film. A three-point bending test was conducted to compare the flexural properties. The results show that such sustainable sandwich composites will be an excellent material for truck side panel to operate in adverse wind/storm conditions. The sustainable sandwich composite can potentially be an excellent candidate for the fabrication of light-duty, lightweight, and low-cost engineering structures in automotive industry to meet the EU end of life requirements.

Today, manufacturing products in a sustainable way is increasingly becoming essential in the eyes of investors, authorities and customers. Failure leads to fines, penalties, and customers choosing to go to the competition. Success, on the other hand, can save money, helps build a reputation, attracts investment, spurs innovation, secures loyal customers and brings in repeat business. Taking into account the sustainable manufacturing is not just longer a caprice for the business.During the end of the twentieth century and into the twenty-first century two types of manufacturing systems that emphasize waste minimization have emerged: Lean and Green manufacturing. Despite the importance of Green manufacturing to the environmental problem, many companies are still skeptical about the business benefits. In the same time, however, a good many of them see the business benefits of Lean manufacturing. Several research efforts summarized in the literature review indicate how both systems share many of the same best practices to reduce their respective wastes. Yet, these two systems tend to operate independently.The aim of this research is to explore and to determine how the Lean manufacturing can include Green manufacturing system components in their overall strategy to reduce waste.

Full textAbstract:
Natural fibers have attracted great attention from industrial players and researchers for the exploitation of polymer composites because of their “greener” nature and contribution to sustainable practice. Various industries have shifted toward sustainable technology in order to improve the balance between the environment and social and economic concerns. This manuscript aims to provide a brief review of the development of the foremost natural fiber-reinforced polymer composite (NFRPC) product designs and their applications. The first part of the manuscript presents a summary of the background of various natural fibers and their composites in the context of engineering applications. The behaviors of NFPCs vary with fiber type, source, and structure. Several drawbacks of NFPCs, e.g., higher water absorption rate, inferior fire resistance, and lower mechanical properties, have limited their applications. This has necessitated the development of good practice in systematic engineering design in order to attain optimized NRPC products. Product design and manufacturing engineering need to move in a mutually considerate manner in order to produce successful natural fiber-based composite material products. The design process involves concept design, material selection, and finally, the manufacturing of the design. Numerous products have been commercialized using natural fibers, e.g., sports equipment, musical instruments, and electronic products. In the end, this review provides a guideline for the product design process based on natural fibers, which subsequently leads to a sustainable design.

Full textAbstract:
Recently, some critical events (e.g., the economic decline, the growing socio-ecologic burden, even more demanding customers, etc.) have led several companies to re-think their “shoring” decisions. Therefore, many of them decided to reshore manufacturing or to bring back home production activities previously offshored. This phenomenon represents one of the current imperatives for research. In fact, the location where manufacturing takes place has a massive influence on the sustainability of firms on a local and global level. Therefore, to better understand what makes reshoring strategies sustainable as well as to identify the drivers that can boost it, further research is still needed. The explorative nature of this paper recognizes some motivations or drivers for making reshoring strategies sustainable. To this end, a structured and narrative literature review has been conducted to grasp and describe the main motivations and implementation characteristics that can make reshoring decisions sustainable. The achieved results better define reshoring and the influence that some drivers, especially digital innovation, can play on the related strategies and on their sustainability. In doing so, this work is one of the first contributions that jointly approaches reshoring, sustainability, and digital innovation.

Full textAbstract:
This study addresses the strategies for developing the cutting tools used in the material removal process called milling from the viewpoint of sustainable manufacturing. Sustainable manufacturing can be achieved by improving the material, energy, and component efficiencies, simultaneously. Cutting tools are just as important as machine tools and process planning to the achievement of the abovementioned efficiencies. Accordingly, this study describes two strategies based on high cutting velocity and feed per revolution, respectively. Exercising the strategy of high cutting velocity requires a Monte Carlo simulation-driven optimization technique. It helps make a balance between the tool material driven environmental burden and the user-defined maximum allowable cutting velocity. Exercising the strategy of high feed per revolution requires an innovative problem-solving procedure (e.g., TRIZ). It helps create novel solutions (e.g., an oval-shaped milling tool) that eliminate the causes of unstable cutting forces or vibrations when the tool passes over sharp corners. Thus, this study clearly shows that developing a milling tool from the viewpoint of sustainable manufacturing requires a multi-faceted approach. Similar strategies can be used to solve the problems involved in developing other cutting tools.

“Sustainability,” a concept leading the 21st Century, calls for the manufacturing industry and its products to achieve sustainability. This issue treats such aspects as CO2 emission and global warming, depletion of natural resources and fossil fuel, and emission of toxic and hazardous substances. Sustainability requires the manufacturing industry to make at least two major changes while maintaining or increasing competitiveness and added product value: 1. Lifecycle thinking requiring manufacturers to design, evaluate, and manage the complete product lifecycle, including use and end-of-life stages. 2. Minimizing everything in the product lifecycle, including products, material and energy use, manufacturing and inverse manufacturing systems, and logistics the consummate lean lifecycle. In this sense, sustainable manufacturing is an extension of current advances in manufacturing technologies, but with an emphasis on wider, holistic applications. This special issue brings together manuscripts discussing vital viewpoints on design and manufacturing moving toward sustainability. The first two papers by Kishita et al. and Matsumoto et al. advocate sustainable resource circulation systems. Papers 3 to 6 by Masui, Sakao et al., Fargnoli, and Fukushige et al. discuss environmentally conscious design. Papers 7 and 8 by Narita et al. and Kondoh et al. propose evaluations of environmental awareness of manufacturing systems. The last three papers by Komoto et al., Takata et al., and Hiraoka et al. discuss postsales activities– collection, and reuse–indispensable to sustainable manufacturing. We thank the authors for their most interesting contributions to this special issue and the reviewers and editors for their invaluable effort, and hope you, our discriminating readers, will begin discussing and implementing ideas and applications for moving the manufacturing industry toward sustainability.

PurposeSustainable end-of-life (Sus-EoL) practices can be achieved through manufacturing of sustainable products, and recovery and recycling after the use phase. To achieve Sus-EoL, the manufacturing organizations should handle their products after their EoL. The recovery of used products is achieved through the design of the collection location. However, the first step is to understand and identify the barriers (e.g. lack of awareness among people, lack of technology, etc.) which prevent the implementation of Sus-EoL practices. The paper aims to discuss these issues.Design/methodology/approachThis paper is about the 18 barriers responsible for the poor success of Sus-EoL practices of used plastic parts. By applying the DEMATEL method and by incorporating experts’ knowledge, a prominence and causal relationship diagram was developed through which the influential strength among barriers was studied.FindingsTheαvalue is computed as 0.068, and the values lower thanαwere eliminated to obtain the digraph. Poor curbside pick is identified as the most dominant barrier in implementation of Sus-EoL practices in plastic parts with an influential score of 3.96.Research limitations/implicationsThe research is conducted in the Indian scenario which could be extended to global context by selecting the suitable barriers.Practical implicationsThe results from the study can be used by the managers of organizations to enhance the possibility of Sus-EoL practices by incorporating suitable strategies which is the significant contribution of this study.Originality/valueIn the past, few authors discussed about the barriers of Sus-EoL practices; however, the analysis of complex interrelationship does not exist. Thus, the global and group interrelationship has been studied which is expected to pave way for future research in the direction of elimination of barriers and so on.

Full textAbstract:
Sustainability is increasingly being addressed globally. The manufacturing industry faces various constraints and opportunities related to sustainable development. Currently, there are few methodological frameworks for evaluating sustainable organizational development. Assessing and improving organizational capacity is important for producers and researchers in the field and local, national, and international authorities. This research proposes a hierarchical framework for sustainability assessment of manufacturing industry in Romania. The proposed framework integrates performance elements and measures to improve all the processes and activities from the triple perspective of sustainability. Sustainability assessment captures the entire supply chain of the organization, including stakeholder interests and end-of-life directions for products. To establish the elements to be integrated in the development of the proposed framework, market research (online questionnaire-for the characterization of Industry 4.0) and the Delphi method were used to identify the categories of performance indicators that must be measured to identify organizational capacity for sustainable development. The framework was tested by an automotive manufacturing organization. A number of improvements have been identified that relate to Industry 4.0 facilities and the application of the facilities related to recovering the value of the product at the end of its life cycle. This hierarchical framework can be customized in detail for the specific of each organization and can be adapted in other industries, including banking, retail, and other services. It can be observed that waste management and the interests of the stakeholders are major implications that must be measured and properly motivated.

Purpose – The purpose of this paper is to review the green manufacturing and similar frameworks in order to trace the origin, definitions, scope, similarities, differences, and publications of these manufacturing frameworks. Design/methodology/approach – A review of 113 research articles is conducted for various terms, namely, green manufacturing (GM); environmentally conscious manufacturing; environmentally responsible manufacturing; environmentally benign manufacturing; sustainable manufacturing; clean manufacturing; cleaner production; sustainable production with reference to triple bottom line, product life cycle engineering, systems approach, resource and energy efficiency, supply chain, pollution prevention and closed loop system/6R. Findings – It can be said with reasonable confidence that all these eight frameworks have been used interchangeably by researchers but it requires some standardization. It has been observed during literature review that to standardize the terminology researchers have to clear emphatically in their research the use of various life cycle engineering approach; clarity on the end-of-life strategies used; clarity in use of various components of triple bottom line perspectives; inclusion of the whole supply chain and integration of environmental improvement strategies with the business strategy. Research limitations/implications – The literature reviewed for the study is the literature available online using Google scholar. Originality/value – This is one of the first known studies to review the GM and similar frameworks for their origin, definition, scope, similarities, and differences.

This paper provides an algorithm for the application of additive manufacturing in the sustainable development of the enterprise. The manufacturing process includes the process of manufacturing preparation, the process of realization of manufacturing (or remanufacturing), the end of the manufacturing process with additional processing and recycling process. A 6R strategy in the realization of new or redesign of existing elements/parts has been implemented. Additive manufacturing or FDM printing technology enables frequent and simple modification of the model at a customer's request, and prior to the model enters the manufacturing itself. The starting material for making the model was polylactic acid (PLA). This paper aims to present the procedure of the realization of an electronics enclosure for a miniature pressure transmitter on a 3D printer. This gives the designer the opportunity to correct existing errors, modify the product according to the requirements of end-users, or to design a completely new product (prototype). In order for the algorithm to get the right confirmation, it is important to design a product that enables: accessibility, easy interchangeability, disassembly, the possibility of finishing and reuse.

As pressure equipment is most commonly used in various industrial fields, making manufacturing processes eco-friendlier (e.g., mass reduction of the final product, material and energy savings, etc.) and transitioning to sustainable production by developing eco-innovative products will have a positive effect on the environment. The aim of this paper is to analyze globe valve housing exposed to internal pressure using full-field experimental 3D digital image correlation (3D-DIC) method and numerical strain and stress data in order to propose improvements for more sustainable development, with respect to practical engineering application of EN standards. The highest von Mises strain values around 0.03% were measured on the point of highest geometrical discontinuity, sphere/cylinder intersection. Stresses of the examined globe valve using numerical and theoretical approach are significantly below material yield limit and allowable stress for internal pressure values of 30 bar, that is significantly higher than nominal operating pressure of 6 bar, proving that structure is over-dimensioned and can be optimized. New experimental procedure development and application in full-field strain analysis contributes to increased valve housing reliability, mass reduction and material and energy savings during manufacturing which directly affects its eco-friendliness, lowers manufacturing price and increases market competitiveness.

Laser-metal additive manufacturing capabilities have advanced from single-material printing to multimaterial/multifunctional design and manufacturing. Material-structure-performance integrated additive manufacturing (MSPI-AM) represents a path toward the integral manufacturing of end-use components with innovative structures and multimaterial layouts to meet the increasing demand from industries such as aviation, aerospace, automobile manufacturing, and energy production. We highlight two methodological ideas for MSPI-AM—“the right materials printed in the right positions” and “unique structures printed for unique functions”—to realize major improvements in performance and function. We establish how cross-scale mechanisms to coordinate nano/microscale material development, mesoscale process monitoring, and macroscale structure and performance control can be used proactively to achieve high performance with multifunctionality. MSPI-AM exemplifies the revolution of design and manufacturing strategies for AM and its technological enhancement and sustainable development.

Full textAbstract:
Apparel manufacturing involves high water consumption and heavy water pollution in its supply chain, e.g., planting cotton, producing chemical fibers, and dyeing. This study employs a multi-regional input–output (MRIO) model to (1) assess the life cycle of blue and grey water (chemical oxygen demand (COD) specific) of China’s apparel manufacturing; (2) reveal the hidden linkage among sectors and regions in the whole supply chain; and (3) identify the key regions and upstream sectors with the most water consumption and heaviest water pollution. We found that the agricultural sector (i.e., planting fiber crops) is responsible for primary water consumption and water pollution. In addition, different provinces assume different production roles. Guangdong is a major output province in apparel manufacturing. However, its economic output is contributed to by other regions, such as blue water from Xinjiang and Jiangsu and grey water from Hebei and Shandong. Our research reveals the significance of taking an inter-regional perspective on water resource issues throughout the supply chain in apparel manufacturing. The sustainable development of China’s apparel manufacturing relies on improving water-use efficiency and reasonable industrial layout.

Purpose The main purpose of this paper is to analyze the current state of a bonnet-manufacturing industry and to optimize the process by designing a future state map using simulation approach. Design/methodology/approach The case study approach has been proposed to highlight the applicability of value stream mapping (VSM) in an Indian bonnet manufacturing organization. The methodology used relies on formulation of VSM being the main tool used to identify the opportunities for classifying and eliminating bottlenecks with the help of various lean techniques. A contrast of present and past scenarios is highlighted to underscore the importance of using VSM with ARENA simulation. Findings Application of the proposed simulation approach has helped the organization reduce the cycle time significantly by 30 per cent over the entire production time. The average number of work-in-progress pieces has also decreased by about ten. In addition, enhancements have been seen with respect to ecological parameters, e.g. carbon footprint has been reduced to 83.7 percent across the process. Research limitations/implications The proposed approach of using a simulation-based VSM helps in reducing the time involved in traditional VSM method. This approach is also easy to implement at any organizational level. Practical implications It is believed that this paper will aid not just industrialists but also academic professionals to appreciate the role of simulation using ARENA in helping them understand how to attack the various problems faced by industries. The results of the study indicate that by applying this methodology, there will be a reduction not only in cost but also in environmental impacts. Originality/value The paper incorporates a real case study, which shows application of VSM for implementing lean principles in a bonnet-manufacturing industry. Break-even analysis presented fills the gap which previous literatures have been missing.

Full textAbstract:
A “digital twin” is a dynamic, digital replica of a technical object (e.g., a physical system, device, machine or production process) or a living organism. Using this type of solution has become an integral part of Industry 4.0, offering businesses tangible benefits, in addition to being particularly effective within the context of sustainable production and maintenance. The purpose of this paper is to present the results of research on the development of digital twins of technical objects, which involved data acquisition and their conversion into knowledge, the use of physical models to simulate tasks and processes, and the use of simulation models to improve the physical tasks and processes. In addition, monitoring processes and process parameters allow for the continued improvement of existing processes as regards intelligent eco-designing and planning and monitoring production processes while taking into account sustainable production and maintenance.

Full textAbstract:
The psychology of sustainability in terms of sustainable development for work–family conflict (WFC) in organizations has become increasingly relevant in sustainable human resource management research, and the pursuit of sustainable creative performance is an important aspect of corporate sustainable development. Taking a regulatory focus perspective, this study integrates a moderated-mediation model to examine the relationship between work–family conflict and sustainable creative performance. Data were collected from 203 supervisor–subordinate dyads from two branches of a high-end manufacturing enterprise in Shanghai, China. The results reveal that work–family conflict has a positive effect on sustainable creative performance through job crafting, and the effect is stronger when individuals show higher promotion regulatory focus. We discuss the theoretical and practical implications of the study, along with potential future research directions.

In line with the striving for a more sustainable orientation in manufacturing systems and industrial pursuit of resource efficiency, companies are looking for efficient processes. The consumption of electrical energy and other resources during the manufacturing phase is considered by the ecological footprint. This study offers a conception for the determination of the ecological footprint within manufacturing systems based on life cycle assessments. The existence of basic data is a requirement for such an evaluation. Therefore, a holistic measurement system is presented which is adaptable to small as well as large scaled production environments and different usage scenarios, e.g. full scale measurement or detailed process analysis.

Full textAbstract:
This paper proposes a conceptual model to support sustainable product design. The approach develops an integrated multimodal decision making model which is to be introduced early in the design process, as the basis for the integration of the life cycle assessment into an Eco-design model. The model, which is based upon an adapted “House of Quality” analysis, supports designers when assessing the environmental impact of the product design. The resulting Eco-design model evaluates the sustainability of the designed product using criteria that consider the impact of manufacturing process, product usage and end-of-life (EoL) disposal strategy. This approach is demonstrated using a case study that considers the design of a set of crocodile medical forceps, in which the redesign of a new forceps is undertaken by considering all the parameters in the Eco-design model.

Purpose – This paper aims to present a methodology to help end-users to find appropriate part candidates for the use of the additive manufacturing (AM) technology. These shall be capable of bringing AM into their businesses. The concept furthermore includes approaches for redesigning current available parts and helps to estimate the economic implications of the use of the technology. Design/methodology/approach – The approach starts to discuss general economic aspects for the successful use of AM. While describing the introduction of new technologies into existing businesses, the importance of an appropriate part selection for AM is pointed out. A methodology for a part selection process is presented, and the different criteria are developed. An approach for a redesign of the selected parts, including the gathering of requirements, is given based on different sample parts. A variation of criteria to include measures for product piracy is highlighted. Findings – The methodology has proven applicability in several research and industry projects in aerospace applications. Independent part selections from experts analyzed within a project of the European Space Agency had a 90 per cent overlap with the results. It allows companies with only basic AM knowledge to start a part screening for applicable AM candidates in their own company with a reasonable effort. Originality/value – The methodology for the redesign process helps to identify the main functions of the products targeted and the relevant environment, so one can benefit from the various advantages that AM has to offer. The selection methodology helps to ask the right questions and to reduce the effort.

Full textAbstract:
Manufacturing systems under Industry 4.0, and their transition towards Industry 5.0, take into account the Quintuple Helix innovation model, associated with the sustainable development goals (SDGs) set by the UN and Horizon 2030, in which companies focus on operational efficiency in terms of the use and minimisation of resources for the protection of the environment. In this respect, the implementation of the circular economy model, which requires engineers to acquire appropriate competencies, enabling companies to establish this model at the manufacturing level. Moreover, competence has always been a priority for both the professional and the company. In this sense, connectivism has been called a learning theory for the digital era; this is the reason why a review of the state-of-the-art developments of this paradigm focused on engineering has been carried out. In this sense, the potential of the digital transformation in instruction to formulate an engineering model based on neuro-competences is of great interest, taking the connectivist paradigm as a methodological axis. To this end, a first bibliometric analysis has been carried out to identify the drivers on which to base the design of the neuro-competencies of the instructional engineering environment and the trend towards curriculum development under dual training models. The bibliographical research carried out on the connectivist paradigm has served to identify the trends followed to date in education within the subject area of engineering. These trends have not fully taken into account the leading role of the human factor within the socio-technical cyber-physical systems of sustainable manufacturing (SCSSM). The focus was more on the technology than on the adaptation of the uniqueness of the human factor and the tasks entrusted to him, which entails an additional complexity that needs to be addressed in both academic and professional contexts. In light of the foregoing, an improvement to the acquisition and management of competencies has been proposed to the academic, professional and dual engineering contexts. It is based on the transversal inclusion of the concept of neuro-competence applied to the competence engineering (CE) model, transforming it into the neuro-competence engineering (NCE) model. The foregoing provides a better match between the characteristics of the human factor and the uniqueness of the tasks performed by the engineer, incorporating activity theory (AT), the law of variety required (LVR), the connectivist paradigm and neuroscience as a transversal driver of innovation through fractality. This proposal enables a ubiquitous and sustainable learning model throughout the entire academic and professional life cycle of the engineer, placing it sustainably at the heart of the instructional and professional cyber-physical socio-technical system, thus complying with the SDGs set by the UN and Horizon 2030.

Abstract Production activities of companies significantly impact society and environment. It is high time to re-think many of industry’s practices and to change manufacturing processes in a way that allow the company to increase its competitiveness, while at the same time help to achieve sustainable growth. The sustainable production is a concept that is able to strengthen such transformation. The aim of this paper is to present empirical evidence of implementation of the sustainable production practices in the selected company from metal industry. The principles of the Lowell Center for Sustainable Production (LCSP) are used as a model to assess the main aspects of sustainable production in practices of the company. Empirical evidence shows that in each of the analysed issue some practices have been implemented, however there were identified some deficit areas. Therefore, at the end of the paper the improvements actions were proposed that could be implemented in the analysed company as part of the sustainable management programme.

Nowadays, manufacturing high product variety is essential for manufacturing companies in order to be sustainable in a volatile market. However, maintaining a shorter lead time in manufacturing operations is also crucial as the speed delivery becomes one of the manufacturing competitive priorities. Motivated by this issue, this study aims to develop a model of Time Loss (TL) for sub-assembly processes in automotive industry. In relation to this, critical elements of TL will be clearly justified through a thorough analysis of literature study in the aspects of Man, Machine, Method, and Material (4M). In this study, the critical elements of TL is defined as an unnecessary activity that needs to be eliminated or minimized. The relationships between the critical elements of TL are clarified through the flow of activities involved in the concept of manufacturing input-output. Finally, the critical elements of TL are compared to the existing non-financial manufacturing performance measures presented in isolated models (e.g. leanness, agility, responsiveness, etc.). Results of the analysis show that the critical elements of TL can be represented as a holistic performance measure of manufacturing operations that includes leanness, agility, fitness, responsiveness, flexibility, and sustainability.

This paper aims to provide an insight to later researchers on the application of axiomatic design in the area of design for end-of-life (EOL) management. Among all life cycle stages of a product, design and development stage is the one that influences the later stages the most in terms of environmental impacts. In order to achieve sustainable product development, one of the considerations to be taken during the design stage is EOL management. EOL management process can be enhanced by utilizing a robust design method as well as an effective method for evaluating product design. Recent researches show that application of axiomatic design in the field of eco-design (especially design for EOL management) is still in a premature stage despite having a vast application area that covers the aspect of product design, manufacturing and supply chain management. Nonetheless, a case study published recently on eco-design using axiomatic approach has shown adequate feasibility and effectiveness. Therefore, design for sustainable EOL using axiomatic approach is worth further exploration.

The construction sector is a resource-driven and resource-dependent industry. A rising global interest to incorporate sustainability principles in the policy-making means a careful balancing of economic growth with sustainability. To achieve this end in the Indian building sector, a triple-bottom-line-based building assessment tool like GRIHA and IGBC was introduced for assessing building sustainability. However, to revitalize the ideas of Reduce, Replace, Reuse, Recycle and Renovate (the ‘5Rs’) into implementable solutions, the technological dimension is introduced to form a quadruple bottom line (QBL) approach, i.e., social, environmental, economic and technological (SEET), for achieving sustainable construction. This study aims to address the necessity to add a new dimension, viz. technological advances in the sustainability arena of the construction industry. The objective of the study is to include technological advances in building materials, construction processes and techniques and design philosophies in the developed SBAT framework. In this extended and upgraded SBAT 2.0, advances in sustainability (AS) criterion accounts for 11.5 per cent showing its significance in achieving building sustainability. The use of discrete reinforcement, additive manufacturing, 3D printing, design based on packing density and rheological properties of concrete, use of alkali-activated materials in the mix-design and performance-based design concepts that affect future sustainability are successfully brought into the fold of SBAT framework.

Full textAbstract:
Bioinspired design has been applied in sustainable design (e.g., lightweight structures) to learn from nature and support material structure functionalities. Natural structures usually require modification in practice because they were evolved in natural environmental conditions that can be different from industrial applications. Topology optimization is a method to find the optimal design solution by considering the material external physical environment. Therefore, integrating topology optimization into bioinspired design can benefit sustainable material structure designers in meeting the purpose of using bioinspired concepts to find the optimal solution in the material functional environment. Current research in both sustainable design and materials science, however, has not led to a method to assist material structure designers to design structures with bioinspired concepts and use topology optimization to find the optimal solution. Systems thinking can seamlessly fill this gap and provide a systemic methodology to achieve this goal. The objective of this research is to develop a systems approach that incorporates topology optimization into bioinspired design, and simultaneously takes into consideration additive manufacturing processing conditions to ensure the material structure functionality. The method is demonstrated with three lightweight material structure designs: spiderweb, turtle shell, and maze. Environmental impact assessment and finite element analysis were conducted to evaluate the functionality and emissions of the designs. This research contributes to the sustainable design knowledge by providing an innovative systems thinking-based bioinspired design of material structures. In addition, the research results enhance materials knowledge with an understanding of mechanical properties of three material structures: turtle shell, spiderweb, and maze. This research systemically connects four disciplines, including bioinspired design, manufacturing, systems thinking, and lightweight structure materials.

This article addresses the issue of educating engineering students with the knowledge and skills of Computer-Aided Design and Manufacturing (CAD/CAM). In particular, three carefully designed tutorials—cutting tool offsetting, tool-path generation for freeform surfaces, and the integration of advanced machine tools (e.g., hexapod-based machine tools) with solid modeling—are described. The tutorials help students gain an in-depth understanding of how the CAD/CAM-relevant hardware devices and software packages work in real-life settings. At the same time, the tutorials help students achieve the following educational outcomes: (1) an ability to apply the knowledge of mathematics, science, and engineering; (2) an ability to design a system, component, or process to meet the desired needs, (3) an ability to identify, formulate, and solve engineering problems; and (4) an ability to use the techniques, skills, and modern engineering tools that are necessary for engineering practice. The tutorials can be modified for incorporating other contemporary issues (e.g., additive manufacturing, reverse engineering, and sustainable manufacturing), which can be delved into as a natural extension of this study.

The most basic and primary building material for construction of houses is the conventional brick. The rapid growth in today’s construction industry has obliged the civil engineers in searching for more efficient and durable alternatives far beyond the limitations of the conventional brick production [1-2]. A number of studies have been made and serious steps have been taken in manufacturing of bricks from several waste materials. However, the traditional mean of bricks production which has brought hazardous impacts to the context has not yet been changed or replaced by more efficient and sustainable one [3], [4]. Most of the researches went through enhancing the clay brick quality and properties by mixing the clay with various recycled wastes as foundry sand, granite sawing waste, harbour sediments, perlite, sugarcane, baggase ash, clay waste and fine waste of boron, sewage sludge, waste glass from structural wall and other different wastes. Compile this state of the art work of manufacturing bricks in the past and the current trend in the bricks industry with respect to the raw materials, ways of manufacturing and the out- comings.This project presents an experimental study on the utilization of waste materials which replaces clay with (Plastic covers, Ceramic Powder, Egg Shell Powder, GGBS, Silica Fume, Rice Husk Ash and Lime Powder) and Fine Aggregate with (Recycled glass, Dry Grass, Dead Leaves, Tree barks powder, Sugar cane powder, crumbed rubber) to produce eco-friendly Bricks. This project is an attempt to fill the gap of the past studies and suggest more sustainable and sophisticated methods of brick manufacturing in the future. 40 percent replacement of fine aggregate with crumbled rubber and dry grass in mortar bricks have given encouraging results, also the replacement of cement by egg shell powder at 20% has given a considerable result

Full textAbstract:
Morphing structures are often engineered with stresses introduced into a flat sheet by leveraging structural anisotropy or compositional heterogeneity. Here, we identify a simple and universal diffusion-based mechanism to enable a transient morphing effect in structures with parametric surface grooves, which can be realized with a single material and fabricated using low-cost manufacturing methods (e.g., stamping, molding, and casting). We demonstrate from quantitative experiments and multiphysics simulations that parametric surface grooving can induce temporary asynchronous swelling or deswelling and can transform flat objects into designed, three-dimensional shapes. By tuning the grooving pattern, we can achieve both zero (e.g., helices) and nonzero (e.g., saddles) Gaussian curvature geometries. This mechanism allows us to demonstrate approaches that could improve the efficiency of certain food manufacturing processes and facilitate the sustainable packaging of food, for instance, by creating morphing pasta that can be flat-packed to reduce the air space in the packaging.

The subject of the research is financial policy, tax regulation and mechanisms for ensuring advanced innovative sustainable development of the manufacturing industries, given the low investment attractiveness of the Russian economy. The purpose of the research was to seek tools and the most effective and efficient sources of financing national goals and strategic objectives of the Russian Federation development. The research used the dialectical method, the inductive and deductive approaches, the index method as well as grouping, comparisons, descriptive analysis, statutes and regulations, data of the Russian Statistical Service (Rosstat) and related publications.Based on the research findings, it is concluded that the effective and competitive innovative development of the domestic industry is hardly feasible without enhancing the competitive advantages and investment attractiveness of the Russian business. To this end, it is proposed to take the best advantage of Russia’s national natural wealth through its more equitable distribution by equalizing the potentials of the extractive and manufacturing industries as well as better financing of the country’s socio-economic development. Tax regulation tools are proposed to bring the Russian economy out of dependence on fuel and raw materials exports and ensure more efficient use of national natural resources as the main competitive edge of the Russian economy, the most important factor of investment attractiveness and a source of wealth for the entire population. The scientific novelty of the study is the substantiation of the proposed measures aimed at tax regulation improvement making it possible to increase financial flows directed to the innovative development of manufacturing industries as well as the state budget revenues thereby enhancing the competitiveness and investment attractiveness of the above industries along with relieving the national economy from the fuel and raw materials dependence.

Full textAbstract:
Industry 4.0, an information and communication umbrella of terms that includes the Internet of Things (IoT) and cyber-physical systems, aims to ensure the future of the manufacturing industry competing in a proper environment of mass customization: demand for short delivery time, high quality, and small-lot products. Within this context of an Industry 4.0 mass customization environment, success depends on its sustainability, where the latter can only be achieved by the manufacturing efficiency of the smart factory-based Industry 4.0 transforming processes. Even though Industry 4.0 is associated with an optimal resource and energy productivity/efficiency, it becomes necessary to answer if the integration of Industry 4.0 elements (like CPS) has a favorable sustainability payoff. This requires performing energy consumption what-if analyses. The original contribution of this paper is the use of the entropy-based formulation as an alternative way of performing the initial steps of the energy consumption what-if analyses. The usefulness of the proposed approach is demonstrated by comparing the results of a discrete-event simulation model of mass customization 4.0 environment and the values obtained by using the entropy-based formulation. The obtained results suggest that the entropy-based formulation acts as a fairly good trend indicator of the system’s performance parameters increase/decrease. The managerial implications of these findings are presented at the end of this document.
