Environmental awareness of the effects of single-use plastic packaging and the shortage of non-renewable resources have encouraged the search for alternative materials. Most of single-use plastic packaging is in the food sector, including bags, straws, bottle lids, coffee stirrers, soda and water bottles. Biopolymers and biocomposites have a high potential to be eco-friendly, economic and technically competitive with fossil-based plastics and conventional composites. This paper presents a case study of life-cycle analysis supporting the design and development of a bottle lid as food packaging by applying a life-cycle engineering methodology to select a biocomposite material. Two current materials with high density polyethylene (HDPE) and polylactic acid (PLA) and 10 alternative biocomposite materials of hybrid matrix (mixtures of HDPE and PLA) and contents of banana fibre (BF) were evaluated. The analysis is performed by integrating of life cycle assessment, life cycle cost and technical analysis. The results show that the material with higher BF content is the best alternative both technically and environmentally, while the material with lower BF content is the best alternative economically. Therefore, the importance attributed to each dimension of analysis is pondered and traded-off to allow an aggregated analysis of the alternatives and a well-informed decision-making.

The potential applications of Additive Manufacturing technologies are capturing the interest of researchers and industries. Many researchers are now focusing on additive manufacturing and its potential to change the industrial paradigm in terms of economic, environmental, and social sustainability. One of the most promising areas for additive manufacturing adoption is maintenance, more specifically, manufacturing of spare parts. The customization potential, and excellent small series capabilities of AM can lead to reductions in size of central and local storages, eliminate the need to locate uncommon spare parts in the distribution network, shorten supply chains and diminish the duration and cost of logistics. The case for replacing conventional spare parts with additive manufactured equivalents has been the discussed in various studies focused of the aeronautic sector, however, its potential in other industries remains relatively unexplored. The continuous process industry is characterized by extremely high production volumes with costly machines and downtime. The combination of these characteristics with intermittent spare part demand patterns and the predominance of reactive maintenance, drives companies to keep large spare parts stock, which makes the case for introducing AM in process industry maintenance very appealing. This study focuses on how AM could change maintenance activities/supply chain in process industries and its economic impact using process based cost models. To further illustrate and study the problem, this paper contains a detailed evaluation of AM’s potential and impacts in a case study from the paper and pulp industry.

Urban Air Mobility (UAM), recently envisioned as faster and flexible mean of transportation in large urban centers, faces considerable challenges inherent in its operation in densely populated cities and related environmental issues such as pollutant and noise emissions. To address the environmental challenges, the proposed concepts are either hybrid-electric or all-electric vehicles enabled with propellers that rotate at lower speeds than conventional rotorcraft configurations, such as helicopters. However, the feasibility of UAM in the near future requires significant progress on the all-electric propulsion systems since current battery technology still falls short when compared with fossil fuel in terms of specific energy density. In this work, a methodology is proposed to evaluate the environmental footprint of Vertical Take-Off and Landing (VTOL) aircraft for the UAM market. This methodology is applied to existing concepts for exploratory studies on mission critical performance and environmental parameters. All-electric aircraft were found to be feasible for the UAM segment from the performance perspective. However, further improvements in battery technology and electricity generation from renewable sources are required. Sustainable aviation fuels, such as Alcohol-To-Jet (ATJ) obtained from wheat straw, present a substantially lower environmental impact than conventional fuels while providing the same performance. These biofuels also contribute less to global warming and climate changes than batteries which: (i) are recharged from electric grids still dependable on non-renewable sources; and (ii) have a low number of recharge–discharge cycles.

One of the most promising areas for additive manufacturing (AM) adoption is in the healthcare industry, through its ability to produce customized medical devices with personalized fit, feel and functionality. The shift from conventional manufacturing systems to AM implies several changes throughout the medical product’s life cycle phases, from workforce qualification to the relationship with customers. This study investigates the social impact of adopting AM in the medical devices industry. To this end, two case studies related to medical devices were developed: a prosthesis and an orthosis, by applying a social life cycle assessment (S-LCA) methodology. The methodology measures and compares performance and impact of developing, producing, and using the two devices produced by AM, and by conventional processes. The results show how the different stakeholders along the product life cycle stages are affected by the change in the manufacturing technology. Evidence of positive social impacts were found in the ‘Customers’, ‘Local community’ and ‘Society’ stakeholders. A negative social impact was found for the stakeholder ‘Value chain actors’. Furthermore, this study illustrates the suitability of the S-LCA methodology to pinpoint the benefits and negative impacts of AM in each case under study.

The topic of sustainable business models is growing in literature and in the industry, driving companies to search for opportunities to improve their impact on the three pillars of sustainability—profit, people, and planet (economic, social, and environmental). However, the process of developing sustainable business models is often complex, due to conflicting objectives from the three dimensions of sustainability. This paper presents a procedure model that supports the design and assessment of business models with a sustainable perspective, by integrating a new business model canvas for sustainability (BMCS) and an evaluation method to assess it. A comprehensive assessment is proposed, performed in a life cycle perspective. The proposed model is applied and validated with a real case study, based on a new business model for an aircraft maintenance, repair, and overhaul company. The case is based on shifting from traditional maintenance, repair, and overhaul activities to adopting additive manufacturing as an activity that allows manufacturing optimized spare parts with benefits for the costumer. The results show the application of the procedure model on a specific case study, as well as the potential of additive manufacturing as a driver for more sustainable business models in the aircraft maintenance sector.

Additive manufacturing has the potential to make a longstanding impact on the manufacturing world and is a core element of the Fourth Industrial Revolution. Additive manufacturing signifies a new disruptive path on how we will produce parts and products. Several studies suggest this technology could foster sustainability into manufacturing systems based on its potential of optimizing material consumption, creating new shapes, customizing designs and shortening production times that, all combined, will greatly transform some of the existing business models. Although it requires reaching a certain level of design maturity to completely insert this technology in an industrial setting, additive manufacturing has the potential to favorably impact the manufacturing sector by reducing costs in production, logistics, inventories, and in the development and industrialization of a new product. The transformation of the industry and the acceleration of the adopting rate of new technologies is driving organizational strategy. Thus, through the lenses of Industry 4.0 and its technological concepts, this paper aims to contribute to the knowledge about the impacts of additive manufacturing technology on sustainable business models. This aim is accomplished through a proposed framework, as well as the models and scales that can be used to determine these impacts. The effects are assessed by taking into account the social, environmental and economic impacts of additive manufacturing on business models and for all these three dimensions a balanced scorecard structure is proposed.

Additive manufacturing (AM) is an emerging technology that is changing the supply chain’s structure in a context where consumers are looking for more diversified, customizable, and yet more environmentally friendly products and technologies. The literature suggests that AM technology improves the efficiency of a supply chain by contributing to waste reduction, elimination of many assembly steps, and less energy consumption, which in turn results in “leaner” and “greener” production processes. To further investigate such implications of AM technology, this study collects anecdotal evidence from research papers regarding the impact of AM on supporting four of the lean/green supply chain practices. As a result, a theoretical framework is developed; and in a final research stage, it is discussed in an interview with a company manager. This paper’s main contribution is to provide a theoretical and managerial perspective on how the AM technology can support lean/green supply chain practices helping to achieve a better supply chain performance.

The industrial sector is under an increasing pressure to achieve quality products with the lowest possible cost and environmental impacts, leading to the necessity of developing methods to support management decision. The Material Flow Cost Accounting (MFCA) and the Lean Management tools usually provide that support, separately. The MFCA assess the economic and environmental performance of the production system, evaluating the physical flows in monetary units, presenting the results in terms of costs of the product itself and the waste. The Lean philosophy analyses, mainly, the physical flows and physical waste. Lean methods/tools allow the diagnosis of different systems and uses problem solving strategies towards continuous improving. This paper present an approach combining both methods/tools, MFCA and Lean, supported by its application to a real case study. This approach allows a clear and quick identification of critical cost and energy related problems, allowing an early problem-solving phase.

Additive manufacturing (AM) is a group of technologies that create objects by adding material layer upon layer, in precise geometric shapes. They are amongst the most disruptive technologies nowadays, potentially changing value chains from the design process to the end-of-life, providing significant advantages over traditional manufacturing processes in terms of flexibility in design and production and waste minimization. Nevertheless, sustainability assessment should also be included in the research agenda as these technologies affect the People, the Planet and the Profit: the three-bottom line (3BL) assessment framework. Moreover, AM sustainability depends on each product and context that strengthens the need for its assessment through the 3BL framework. This paper explores the literature on AM sustainability, and the results are mapped in a framework aiming to support comprehensive assessments of the AM impacts in the 3BL dimensions by companies and researchers. To sustain the coherence of boundaries, three life cycle methods are proposed, each one for a specific dimension of the 3BL analysis, and two illustrative case studies are shown to exemplify the model.

The aeronautic industry is facing increasing pressure to design more efficient and sustainable aircraft to mitigate their impact on the environment. These solutions are mainly focused on: aerodynamics, structures/materials, propulsion and operations. This paper focuses on the potential of electric propulsion systems in different aircraft segments for reducing the environmental impact in the aircraft life cycle. With a twofold contribution and linking different areas, this study presents a methodological proposal for the environmental assessment of the propulsion system change in a consequential Life Cycle Assessment perspective. This methodology uses data from both a modified conceptual aircraft design adapted to hybrid-electric aircraft and a battery study. Results show not only the environmental impacts of the required battery systems for each aircraft segment in a life cycle perspective, but also in what contexts the hybrid-electric propulsion may be considered a best alternative environmentally when compared with fuel propulsion systems. For that, a sensitivity analysis illustrate the results for different electricity mix contexts and for different battery cell capacities. The main contribution for the overall life cycle impact is the process of charging a battery system, therefore the source of electricity generation is crucial for the environmental sustainability of a hybrid-electric aircraft.

Despite the myriad of possibilities and applications of additive manufacturing (AM) technology, knowledge about the social impacts of this technology is very scarce and very limited in some areas. This paper explores how factors generated by the development of AM technology may create social impacts, affecting the health and social well-being of people, quality of life, working conditions, and the creation of wealth. This paper presents the results of an exploratory multiple case study conducted among four Portuguese organizations that use AM technology, aiming to determine their perceptions regarding the social impacts of AM, its effects, and causes. The results confirm that AM technology is mainly seen to create positive impacts on health and safety (regarding physical hazards), on expectations for the future, on leisure and recreation, on low disruption with the local economy, on economic prosperity, on the professional status, and on innovative employment types. Nevertheless, a negative impact was also found on health and safety (concerning hazardous substances), as well as several mixed and null impacts. The main limitations of the research arise from the use of a case study methodology, since the results can be influenced by contextual factors, such as the size of the organizations in the sample, and/or social, cultural, technological, political, economic, and ecological factors. This study gives an up-to-date contribution to the topic of AM social impacts and social changes, an area which is still little-explored in the literature.

The eco-efficiency assessment is a powerful metric to introduce two components of sustainability assessment in the industrial companies' decisions making: the concurrent consideration of economic and environmental performance. The application of the eco-efficiency concept and of the normative documents is not an easy task, mainly because there are myriad environmental related indicator to consider and acquire. This barrier is higher in the realm of plastic injection molding, where each mold is unique, requiring a recurrent effort of data retrieving for such one-of-a-kind molds. To overcome this barrier, an integrated framework to support the eco-efficiency calculation on a life cycle perspective for a specific type of products, injection molds, is proposed in this chapter. It retrieves a small but representative selected set of eco-efficiency performance indicators. A tool was developed to apply the proposed framework and the results of its application to four real industrial case studies is discussed.

In the European Union (EU), the use of fossil fuels brings several disadvantages, as they are the main culprits responsible for pollutants and GHG emissions. The increasing demand for sustainable fuels leads to the research of alternative technologies, such as biogas production from lignocellulosic materials. Therefore, the acquisition of biomass from marginal areas under Danish conditions has been evaluated in terms of alternative harvesting equipment: an automated robot (Grassbot) versus a regular tractor for key grass materials used for biogas plants (chopped, unchopped, and baled grass) and compared regarding operational, economical, and environmental performances. The evaluation uses two operations models (IRIS and DRIFT) to consider the field characteristics, machinery characteristics, etc. Selected results show that in terms of fuel consumption, chopping, and mowing are the most demanding operations, and that there is no significant difference between the harvesting equipment regarding CO2 emissions.

Micro-engineering is nowadays a key industrial area with applications is a wide range of products and sectors. The need for a multiplicity of products fostered the development of several processes and combinations of processes in the world of micro-engineering. There are different feasible alternatives to produce the same kind of product. The manufacturing cost is usually the decision factor to select the best alternative among them. But cost is affected by dozens of factors and if not properly modelled causes controversy in so complex decisions. In this chapter, the application of process-based cost modelling is proposed as the engine to identify the best performance spaces for each alternative, using its potential for sensitive analysis of uncertain and/or critical parameters. To illustrate the approach, a case study is developed analyzing four alternatives for the production of a light diffuser with micro-features imbibed, involving micro-injection molding, hot-embossing, micromachining, and powder-injection molding.

Eco-efficiency is a prominent as well as promising approach for fostering sustainability by assessing the environmental impact and value of companies’ activities simultaneously. A lot of indicators to assess both pillars—environmental and economic effects—are presented in different standards and guidelines. This chapter develops a methodology for selecting and applying indicators for the application of eco-efficiency to support decision-making, internal, and external communication at product level. The chapter starts with outlining the motivation and presenting a brief literature review as well as the intended contribution. Thereafter, the methodology for the stepwise selection of a manageable number of relevant and significant eco-efficiency indicators and the generation of the value and environmental profiles as well as eco-efficiency ratios of products are suggested. The methodology is developed against the background of the mold manufacturing and plastic injection molding sector. A case study referring to molds for injection molding demonstrates its application and results.

This chapter studies the potential of additive manufacturing (AM) technologies for injection molds with conformal cooling systems. The analysis is based on a case study intending to compare the performance of conventional machining with two AM technological alternatives: Vacuum Furnace Brazing of metal plates and Direct Metal Laser Sintering. Assuming that the effects of the benefits and drawbacks of the options have different dimensions and time horizons, the comparison is made based on the life cycle perspective of the mold. A Life Cycle Engineering approach is followed, which allows the integrated evaluation of the economic, environmental, and technical performance throughout the mold life. A sensitivity analysis is performed to understand the robustness and is most suitable alternative for different production contexts, taking advantage of the process modeling based on engineering relations. The results show the benefits of AM-based conformal cooling solutions on the mold technical performance, measured by the part quality, together with the economic and environmental advantages for medium to high production volumes.

Technological development has had huge impacts in sports performance throughout the years, fostering the development of specific materials and manufacturing processes for sports-related products. Within this context, a new technology for snowboards was developed taking advantage of the internal coupling effects of Fibre Reinforced Plastics (FRP) using an anisotropic layer design. This work deals with the technical, economic and environmental evaluation of a snowboard made of three alternative materials, namely carbon, glass and flax fibre reinforced plastics. It shows how a life cycle analysis can support the design and development of products by applying a Life Cycle Engineering methodology to the design process of a snowboard using an innovative technology. In this case, both the material choice and the fiber placement angles have a significant impact on the stiffness of the resulting FRP and thus in the three dimensions of analysis - cost, environmental and technical. The natural fiber is the most sustainable option environmentally, the glass fiber is the best one economically and the carbon fibre is the best in terms of technical performance. Therefore, the importance attributed to each dimension of analysis is pondered and traded-off to allow an aggregated analysis of the alternatives and a well-informed decision-making.

Composite material usage in aircraft has been rising since the 1990s, with significant increases in manufacturing productivity and repeatability due to automation in the production of aeronautic parts made of composite materials, becoming a strong driver for widespread adoption of composites in this industry. Automated Tape Layup (ATL) and Automated Fibre Placement (AFP) are two of the most important automated manufacturing technologies within aeronautics composites, although their cost implications and economic comparison have not been widely studied. This paper presents an economic evaluation of ATL and AFP technologies. Using process-based cost models, the manufacturing process of a horizontal stabiliser is modelled, determining for each technology the associated consumption and use of resources and their implications towards the part final cost. Results show that ATL is less expensive than AFP, due to lower material costs, although with less material efficiency and slower cycle time.
