As nearly one third of global energy demand and CO2 emissions are attributable to manufacturing activities, the reduction of energy/resource consumption in the industrial sector is increasingly crucial. Therefore, research and innovation for the factories of the future is not only a matter of developing and integrating new technologies, but also a challenge to make manufacturing less dependent on energy and managed in an optimized way. This requires considering the efficiency of resource exploitation according to a systematic approach. To this aim, the present paper proposes a resource-saving tool, called Resource Value Mapping (RVM), and describes its application in a smart multinational company that produces electromechanical components for the automotive industry. The RVM tool is composed by three main modules that jointly allow the involved stakeholders to collaborate toward the optimization of the plant management: the Cloud data center that represents the repository of the collected real-time and offline data, the Analytics module that is responsible for data elaboration with the aim of calculating a set of key performance indicators useful to identify process inefficiencies, and the Web-based platform that represents the user interface of the tool. The case study demonstrated how such a tool allows (1) mapping the energy/resource flows to multiple levels (machine, line, plant), (2) characterizing them to identify the most critical activities that do not generate value and (3) supporting multiple stakeholders (plant manager, energy manger, operators) in the management of resource anomalies and definition of a more sustainable action plan.

Face masks are currently considered key equipment to protect people against the COVID-19 pandemic. The demand for such devices is considerable, as is the amount of plastic waste generated after their use (approximately 1.6 million tons/day since the outbreak). Even if the sanitary emergency must have the maximum priority, environmental concerns require investigation to find possible mitigation solutions. The aim of this work is to develop an eco-design actions guide that supports the design of dedicated masks, in a manner to reduce the negative impacts of these devices on the environment during the pandemic period. Toward this aim, an environmental assessment based on life cycle assessment and circularity assessment (material circularity indicator) of different types of masks have been carried out on (i) a 3D-printed mask with changeable filters, (ii) a surgical mask, (iii) an FFP2 mask with valve, (iv) an FFP2 mask without valve, and (v) a washable mask. Results highlight how reusable masks (i.e., 3D-printed masks and washable masks) are the most sustainable from a life cycle perspective, drastically reducing the environmental impacts in all categories. The outcomes of the analysis provide a framework to derive a set of eco-design guidelines which have been used to design a new device that couples protection requirements against the virus and environmental sustainability.

The fashion industry is responsible for a significant contribution to environmental pressure in the European Union. The present study aims to quantify the environmental impacts of a leather shoe production chain and identify the most criticalities in terms of companies, processes, and materials. The Life Cycle Assessment (LCA) methodology was used to assess the impacts related to the production of a pair of classic man leather shoes. Slaughtering and tanning resulted in the less environmentally sustainable stages for almost all the analysed impact categories, except water resource depletion and ozone layer depletion. Such outcomes are mainly due to the high distance from animals’ skin suppliers to slaughterhouses and tanneries, the use of lorries transport, and the large use of unsustainable chemicals to treat the leather. Going downstream, the main hot spot refers to the use of cotton during upper manufacturing and shoe assembly and finishing. Three alternative realistic production scenarios were simulated to find the best sustainable mix. They focused on alternative means of transport, the substitution of cotton, and green purchasing of upper and lining. An environmental impact reduction of about 30% can be obtained if all the suggested scenarios are implemented.

Product eco-design includes several methodologies aimed at supporting companies in the development of sustainable products. Currently, this theme is assuming an important role in both the academia and industry worlds due to the increasing attention to environmental problems and the need for a transition toward circular economy business/organizational models. In this context, the present paper focuses on the industrial sector of espresso coffee machines manufacturing which has several unexploited potentialities. The analysis of the sector specificity (internal and external contexts), as well as of the product lifecycle allowed to define an eco-design framework to guide companies involved in the design and production of espresso coffee machines. Effective eco-design strategies should include the combined use of specific methods, tools and metrics to manage all the most important lifecycle phases (beginning of life, middle of life, end of life) during the design activities in order to set preventive actions that avoid future potential environmental impacts. Only in this way, the environmental and economic benefits of the circular economy paradigm (e.g. remanufacturing/reuse of selected components) can be practically exploited in real industrial contexts. The presented case studies confirmed that the application of design for disassembly rules positively contributes to increase the product performances during maintenance and end of life, while a re-design oriented to component modularity could be a key strategy to pursue remanufacturing for boilers, a key and expensive component included in espresso coffee machines.

Product customization is largely considered one of the most important competitive factors in several industrial sectors, including high-end footwear. However, in this sector, products are generally manufactured through manual and artisanal operations, processes are not standardized and repeatable, and the personal skills of expert operators play a leading role. The objective of the present paper is to propose a workflow enabled by a framework including several technologies (computer aided design tool, augmented reality systems, traceability infrastructure), to support industrial companies of the high-end footwear sector during the different phases of shoes customization (from configuration to delivery). All these technologies jointly contribute to innovate the shoes customization process by increasing the flexibility of internal processes, improving the ability of companies to answer to specific requirements thanks to the direct involvement of customers, maximizing the efficiency of data sharing, making the organizational, design, production and management processes more efficient and repeatable, and reducing the customer response time.

Eco-design is the integration of environmental considerations within product design and development. Eco-design represents an important innovation driver for companies; however, well-known barriers limit the diffusion of this design paradigm in the industrial world. Amongst these, lack of eco-knowledge is correlated to the adopted eco-design teaching methods. Previous experience has highlighted that traditional teaching methods such as university lectures or refresher courses are not an effective means for disseminating eco-design knowledge in the industrial world. In this context, the present paper proposes a novel eco-design teaching method based on a transformative strategy for promoting eco-design and facilitating the learning process. This approach, tested in collaboration with an Italian manufacturing firm, is considered the first attempt to implement a repeatable eco-design teaching approach that can be scaled up in different industrial contexts. Several company departments, including management, marketing and commercial affairs, design and engineering, and a testing laboratory were involved in the training program. Technical results show that company employees were able to autonomously implement re-design solutions and improve the environmental performance of a coffee machine upon completion of the course. The quantitative evaluation of formative outcomes through assessment before and after the course highlights a significant increase in the awareness of personnel and knowledge relating to eco-design.

The assessment and monitoring of energy and resource efficiency is an essential activity toward the implementation of sustainable manufacturing practices. Existing energy/resource assessment methods and tools are not based on a comprehensive approach, lack on the use of specific key performance indicators, are dedicated to expert stakeholders and do not provide useful suggestions for improving production systems. This paper proposes an innovative method, called Resources Value Mapping that aims to map and classify activities and related energy/resource consumptions according to lean philosophy principles (value-added, non value-added, waste). A user-friendly map and two efficiency indicators (Cost Index and Muda Index) are proposed to quantitatively support the identification of criticalities related to activities, processes, lines, plants, etc., and to successively guide the decision-making process during the improvement strategies implementation. The method has been used to analyze a manufacturing plant that produces cooking appliances. The case study demonstrated the applicability of the method in real industrial contexts and its effectiveness in identifying the energy/resource flows (electricity and compressed air), departments (sheet department) and lines (mechanical and hydraulic presses) for which the waste and non value-added consumptions are prominent. The analysis highlighted that less of 20% of the resources consumed during the process creates value, offering wide margins for improvement. Finally, it aided the definition of an action plan leading to relevant reduction of resource consumptions, economic savings and environmental benefits.

The eco-design of industrial products is a complex task that requires a high level of expertise in environmental science and a very large amount of data about the product under development. Product data for eco-design are not limited to geometrical and technical aspects; they also include information related to the product life cycle. The present paper aims to define a life cycle standard data model (LCSDM) that manages and shares life cycle information along the product development process. The LCSDM is defined as a common and structured framework for data collection in comparative evaluations. The need of a “standard” data model emerges in the context of life cycle assessment (LCA), mainly due to the subjectivity related to the life cycle inventory phase. The standard structure of the LCSDM facilitates the interoperability of eco-design software tools by creating a common framework for the implementation of eco-design initiatives inside product manufacturing companies. The LCSDM is a data structure that is able to represent the relationships among parts and assemblies. Each part or assembly is defined by a set of nodes that characterize the life cycle phases (e.g., Material, Manufacturing, Use, End-of-life, and Transport). A list of attributes is identified according to the environmental features that describe the product life cycle. The LCSDM structure is implemented in an encoding document for data sharing through a generic software language (e.g., XML – eXtensible Markup Language). The implementation of the proposed LCSDM in the design department of a manufacturing company using an eco-design software platform leads to the following benefits: (i) the fulfilment of the LCSDM (XML file) along the product development process, (ii) the use of a unique standard for data sharing among the several eco-design software tools, and (iii) the creation of a robust framework for life cycle assessment. The main drawback of the proposed LCSDM is related to the initial effort required to set up the design software platform (which consists of both standard and eco-design tools) to be able to read, fill, store and share the LCSDM.

The improvement of the waste management efficiency and sustainability in the electronics sector requires the disassembly and reuse of valuable electronic components, instead of their recycling for precious materials recovery. In this context, this study proposes a robotic system for the disassembly of electronic components, grounded on the revamping of an existing soldering machine. First, the feasibility of an automated process for the end of life (EoL) management of electronic boards is investigated: the disassembly and reuse of electronic components represents a potential cost saving opportunity for producers of industrial electronic boards, other than an effective means to improve the environmental sustainability of the electronics sector. Then, the automatic system has been designed; it is mainly composed by a wave soldering machine, a two-axis manipulator equipped with a suction cup for components picking, and a central control unit to coordinate the motion. Finally, the prototype of the disassembly equipment has been realized. The experimental tests aimed at setting the most relevant process parameters (e.g., working temperatures) and verifying the performance of the developed disassembly equipment. Results confirmed the effectiveness and the reliability of the prototype: all the 450 microprocessors disassembled from 50 boards resulted to be not damaged and thus directly reusable in new boards without the need of additional treatments (e.g., washing).

The easy disassembly of certain product components is a prerequisite to guarantee an efficient recovery of parts and materials. This is one of the first step in the implementation of circular economy business models. Design for Disassembly (DfD) is a particular target design methodology supporting engineers in developing industrial products that can be easily disassembled into single components. The paper presents a method and a software tool for quantitatively assessing the disassemblability and recyclability of mechatronic products. The time-based method has been implemented in a software tool, called LeanDfD, which calculates the best disassembly sequences of target components considering disassembly precedencies, liaisons among components, and specific properties to model the real condition of the product at its End-of-Life (EoL). A dedicated repository has been developed to store and classify standard times and corrective factors of each disassembly liaison and operation. This knowledge feeds the two LeanDfD tool modules: (i) product disassemblability module, which allows to carry out the time-based analysis and to improve the disassemblability performance of target components, and (ii) product recyclability module, which estimates the quantities of materials that could be potentially recycled at the product EoL. The LeanDfD tool functionalities have been defined starting from the means of the user stories and the developed tool framework, data structure, databases and use scenarios are described. A group of designers/engineers used the tool during a re-design project of a washing machine, considering the disassemblability as the main driver. The case study highlights how the proposed DfD method and tool are able to support the implementation of re-design actions for improving product de-manufacturability and EoL performance. The LeanDfD features aid engineers in making a quick and robust assessment of their design choices by considering quantitative disassemblability and recyclability metrics.

The increasing focus on environmental practices has led academia and industry to address eco-sustainability in different ways. Recent improvements to supply chain management (SCM) have also included environmental sustainability as a key factor, in addition to common drivers such as risk, supply quality, and cost. Although several eco-sustainable SCM approaches have been proposed, often those solutions remain too theoretical and difficult to implement. This paper contributes to this research topic by proposing a web-based platform capable of tracing suppliers and related processes along the entire product supply chain (SC). This platform is a powerful decision-making tool for improving overall SC environmental sustainability. A structured methodology is defined and implemented that can efficiently model complex SCs, share data between actors, and measure its environmental sustainability. To demonstrate the platform applicability and validate its effectiveness in industrial settings, a case study of industrial partners involved in the production of leather shoes is provided.

The management of end-of-life tyres (ELTs) is regulated by several national and international legislations aiming to promote the recovery of materials and energy from this waste. The three main materials used in tyres are considered: rubber (main product), which is currently reused in other closed-loop applications; steel, which is used for the production of virgin materials; and textile fibres (approximately 10% by weight of ELTs), which are mainly incinerated for energy recovery (open-loop scenario). This study aims to propose and validate a new closed-loop scenario for textile fibres based on material reuse for bituminous conglomerates. The final objective is to verify the technical, environmental, financial, and economic feasibility of the proposed treatment process and reuse scenario. After characterization of the textile material, which is required to determine the technological feasibility, a specific process has been developed to clean, compact, and prepare the fibres for subsequent reuse. A life cycle assessment (LCA) has been carried out to quantify the environmental benefits of reusing the fibres. Finally, a cost benefit analysis based on the LCA results was conducted to establish the long-term financial and economic sustainability. From a technological point of view, the tyre textile fibres could be a promising substitute to the reinforcement cellulose commonly used in asphalts as long as the fibres are properly prepared (compaction and pellet production) for application in the standard bituminous conglomerate production process. From an environmental point of view, relevant benefits in terms of global warming potential and acidification potential reduction were observed in comparison with the standard incineration for energy recovery (respectively −86% and −45%). Moreover, the proposed scenario can be considered as financially viable in the medium to long term (cumulative generated cash flow is positive after the 5th year) and economically sustainable (expected net present value of more than €3,000,000 and economic rate of return of approximately 30%). Finally, the sensitivity and risk analyses show that no specific issues are foreseen for the future implementation in real industrial applications.

Feature-based modeling and feature recognition algorithm are state of the art technologies, mainly used to favor the integration and exchange of data between design and manufacturing phases. This paper aims to investigate the possibility to extend the use of the feature recognition as a means for the prevention of ergonomics issues during the manual assembly phase, such as Work-related Musculo-Skeletal Disorders (WMSDs). Starting from the features analysis of a 3D product model, the proposed five steps method allows preventively identifying potential ergonomics issues. The main novelty of this study is related to the correlation between design tools, product virtual representations (e.g. 3D models), assembly and ergonomics aspects. Results obtained with two case studies, a cooker hood and a tool-holder carousel, confirm the usefulness of the proposed method in helping designers to prevent potential ergonomics issues for operators involved in the assembly phase.

Design for end-of-life and design for disassembly are enabling design strategies for the implementation of business models based on the circular economy paradigm. The paper presents a method for calculating the effective disassembly sequence and time for industrial products. Five steps support designers in defining liaisons and related properties and precedence among components with the aim to calculate the best disassembly sequence and time. The effective disassembly time is computed considering the actual conditions of a product and its components (e.g. deformation, rust and wear) using corrective factors. This aspect represents the main contribution to the state of the art in the field of design for disassembly. The corrective factors are derived from a specific data mining process, based on the observation of real de-manufacturing activities. The proposed approach has been used for calculating the disassembly times of target components in a washing machine and in a coffee machine. The case studies highlight the method reliability of both: definition of time-effective disassembly sequences and assessment of effective disassembly times. In particular, a comparison of experimental tests shows a maximum deviation of −6% for the electric motor of the washing machine and −3% for the water pump of the coffee machine.
