Extending the lifetime of passive products, i.e., products that do not consume materials or energy during the use phase, by implementing product-service systems (PSS) has a potential to reduce the environmental impact while being an attractive and straightforward measure for companies to implement. This research assesses the viability of introducing PSS for passive products, by documenting five real product cases of prolonging the lifetime through repair or refurbishment and by quantifying, through life cycle assessment (LCA) and life cycle costing (LCC), the change in environmental and economic outcome. The environmental impact (measured as global warming potential over the life cycle) was reduced for all cases because extraction and production dominated the impact. This reduction was 45–72% for most cases and mainly influenced by the number of reuses and the relative environmental burden of the components whose lifetime was prolonged. The costs for the company (measured as LCC from the manufacturer’s perspective) decreased too by 8–37%. The main reason that costs reduced less than the environmental impact is that some costs have no equivalent in LCA, e.g., administration and labor costs for services. The decreases in both LCA and LCC results, as well as the willingness of the companies to implement the changes, demonstrate that this measure can be financially attractive for companies to implement and effectively contribute to a circular economy.

Nowadays the heightened awareness of the critical trend in resource depletion impels to improve the eco − sustainability of any productive process. The research presented in this paper aims to quantify the environmental impact of the emerging productive process of edible flowers, focusing on two model species, i.e., Begonia x semperflorens − cultorum hort and Viola cornuta L., and two types of product, i.e., flowering potted plants sold in plastic vases and packaged flowers ready to be consumed. The study was carried out in an Italian nursery located in Tuscany, interviewing the owners in order to complete the Life Cycle Inventory, assessing the value of the impact categories, and using the “cradle to gate” approach. The information about the production of flowering potted plants and packaged flowers were inserted in a database and elaborated by the appropriate software. The results of the Life Cycle Assessment (LCA) analysis referred to 1 g of fresh edible flowers and were expressed in four impact categories. Global Warming Potential (GWP) values ranged from 24.94 to 31.25 g CO2 eq/g flowers, Acidification Potential (AP) ranged from 8.169E − 02 to 1.249E − 01 g SO2 eq/g flowers, Eutrophication Potential (EP) ranged from 3.961E − 02 to 5.284E − 02 g PO43 − eq/g flowers, and Photochemical Ozone Creation Potential (POCP) ranged from 8.998E − 03 to 1.134E − 02 g C2H4 eq/g flowers. Begonias showed lower emissions than violas in the GWP and POCP indexes, whereas violas showed lower values in the AP and EP impact categories. The most impactful phase was the propagation, accounting on average for 42% of the total emissions. Overall, the findings highlighted a higher environmental load for the production of both begonias and violas packaged flowers, especially if in small containers, rather than as potted plants, with an emission percentage increase from 8% to 17% among the impact categories.

Based on the Sustainable Development Goals introduced by the United Nations and on the circular economy concept, ICT providers are adapting to become more sustainable. Some assess the CO2 emissions in the whole life cycle, while others propose to use renewable energies during manufacturing and assembling. In contrast with the current smartphone business models that rely on ongoing patterns of production and consumption, this paper proposes a more sustainable approach by combining product modularity, Product-Service Systems (PSS), and design for attachment. With a modular design, it becomes easier to repair the product or to replace parts, allowing for an extended lifespan. In combination with PSS, we propose that the modules, when no longer used by one customer, return to the market to be reused by another one. Lastly, we discuss the impact of the users’ behaviour through emotional bond, personalization, and technology appropriation as predictors of attachment to the product and consequently an extended lifespan. Through comparing case studies and using Life Cycle Assessment to calculate the CO2 equivalent emissions, we argue that our approach would directly reduce the environmental impact of the smartphone on the production phase, which accounts for most of the emissions throughout its life cycle.

The shift towards Product-Service Systems (PSS) stresses the need to embed new and unique capabilities in Decision Support Systems, with the aim of helping the engineering team in handling the pool of information and knowledge available during decision events. Emerging from a multiple case study in the Swedish manufacturing industry, this paper describes the development of the Model-Driven Decision Arena (MDDA), an environment for collaborative decision-making that focuses on the early design phases of PSS. Based on the findings from multiple case studies, this paper illustrates the main goals of the MDDA, detailing its main functions, its physical environment, and its software architecture and models. This paper demonstrates the use of the MDDA in a case study related to the development of an asphalt compactor, presenting and discussing the results of verification activities conducted with industrial practitioners on the current MDDA prototype.

In recent times, there has been an indisputable need to move towards a more sustainable economy, known as a circular economy, which is basically aimed at reducing the consumption of newly extracted raw materials to manufacture products, and thus, reduces waste generation by recycling products beyond their useful life to ultimately close the economic flow of the product. For the economy generated by products to close the circle, it is essential to tackle the problem at the source, that is, the process to achieve the desired product should be conducted by designing the product with environmental criteria (eco-design) and analysing its life cycle from the extraction process to the point when it ends its useful life (LCA). This article presents an ECO + LCA methodology that provides designers with an easy way of visualising the effect of their design decisions on the final environmental impact of the product. This methodology was tested on a case study of a conventional desk, with four alternative scenarios presented and an assessment of their final impact with a cradle-to-grave perspective. The final design obtained reduces the environmental impact by more than 30% and reduces costs by more than 11%.

The paper proposes a Product-Service System (PSS) methodology for customizing solutions to different patterns of use while achieving a better environmental performance than a stand-alone product. The approach is based on combining the Quality Function Deployment for Product-Service Systems (QFDforPSS) and the Screening Life Cycle Modeling (SLCM) tools. QFDforPSS is augmented by the Fuzzy Analytical Hierarchy Process (FAHP) to reduce service-related ambiguities and uncertainties on the one hand and better define the product and service characteristics of the solution on the other. The SLCM evaluates the possible outcomes by determining the environmental impact and comparing it with the manufacturer’s current solution. A case study at a manufacturer of medical diagnostic equipment illustrates the use of the approach depicting the possible benefits that can arise: the PSS solution can be customized to fit customers who intensively use the product and consumers with a more moderate use. This offers flexibility and an optimized life cycle through easier maintenance, upgrades, and end-of-life schemes. Concretely, it shows how the PSS approach can enhance the development of sustainable solutions that can be adapted to varying and future customer needs, such as adjusting current solutions to new requirements, i.e., adapting existing products to COVID-19 detection and different levels of use.

Coffee silverskin (CSS) is one of the main byproducts of coffee roasting and poses a potential risk to the environment if disposed of incorrectly. Each year in Italy, over 500,000 tonnes of green coffee are imported for roasting followed by consumption or export. This results in over 7500 tonnes of CSS produced each year which is typically disposed of as solid waste. Silverskin contains lignocellulose and can be used as a substitute for other raw materials to produce paper pulp. Both Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) were performed to compare the impact and cost of CSS paper production to conventional paper production using only virgin pulp. It was shown that the addition of CSS reduces the environmental impact of paper production by 10% and greenhouse gas (GHG) emissions by 13% compared to conventional production with no cost increase (0.01% reduction with addition of CSS) for the producer. The results of this case study show that the utilization of CSS for paper production at the national level in Italy represents a suitable example of circular economy (CE).

Many machine tool manufacturers offer services to support their customers over the lifetime of a product. This kind of integration of products and services is called Product-Service Systems (PSS). PSS offer advantages for the customers as well as for PSS providers because they fulfill customers’ requirements and ensure a long and successful customer relationship. Since sustainability is getting more and more important and customers are interested in sustainable solutions, PSS providers need to improve the environmental impact of their products and services continuously. Under this aspect, an approach is necessary that identifies the ecological potential of services for machine tools. In this paper, an approach to analyze the impact of Product-Service Systems on the energy efficiency of machine tools is presented.

Business models like product-service systems (PSSs) often recognise different sustainability goals and are seen as solutions for the impacts of consumption and fast fashion, but there is a lack of evidence supporting the environmental claims of such business models for clothing. The research aimed to understand if rental clothing business models such as PSSs have the environmental benefits often purported by quantifying the environmental impacts of rental formal dresses in a life-cycle assessment (LCA) in a case study in Stockholm, Sweden. The effects of varying consumer behaviour on the potential impact of a PSS vs. linear business model are explored through three functional units and 14 consumption scenarios. How users decide to engage with clothing PSSs dictates the environmental savings potential that a PSS can have, as shown in how many times consumers wear garments, how they use rental to substitute their purchasing or use needs, as well as how consumers travel to rental store locations.

The buildings sector is one of the least sustainable activities in the world, accounting for around 40% of the total global energy demand. With the aim to reduce the environmental impact of this sector, the use of renewable energy sources coupled with energy storage systems in buildings has been investigated in recent years. Innovative solutions for cooling, heating, and domestic hot water in buildings can contribute to the buildings’ decarbonization by achieving a reduction of building electrical consumption needed to keep comfortable conditions. However, the environmental impact of a new system is not only related to its electrical consumption from the grid, but also to the environmental load produced in the manufacturing and disposal stages of system components. This study investigates the environmental impact of an innovative system proposed for residential buildings in Mediterranean climate through a life cycle assessment. The results show that, due to the complexity of the system, the manufacturing and disposal stages have a high environmental impact, which is not compensated by the reduction of the impact during the operational stage. A parametric study was also performed to investigate the effect of the design of the storage system on the overall system impact.
