The capacity to guide the evolution and creation of new products (manufactured goods or services) is crucial for the enterprise's profitability. Hence, enterprises have acquired the capacity to manage the future of their product portfolio. However, companies that offer a combination of manufactured goods and services as an integrated system or a Product-Service System confront challenging conditions to maintain or increase their market share due to the complex relationship between manufacturing and service production systems. The complexity of a PSS makes it challenging to adapt its physical products to new customer requirements, satisfy new standards, or develop/adopt new technologies because any modification in one part of the system will undoubtedly affect the other. Therefore, it is necessary to propose an approach for managing the development process of a PSS from a broad perspective. The approach presented in this article combines the advantages of the Business Model Canvas to define the crucial functions of a business model with the service blueprinting capacity to represent service processes. The proposal describes a five stages methodology: Conceptualization, Business Model Design, Product-Service System (PSS) Scenarios, Blueprint design, and Validation. The methodology helps the analysis of a PSS from three perspectives: product, use, and result, which are the typical PSS scenarios. A case study applied to a company that distributes purified water is helpful to illustrate the methodology. Finally, the methodology includes some aspects that favor implementing creative and dynamic business models, emphasizing the constant changes in the evolution of products and services.

Closing the loop of products and materials in Product Service Systems (PSS) can be approached by designers in several ways. One promising strategy is to invoke a greater sense of ownership of the products and materials that are used within a PSS. To develop and evaluate a design tool in the context of PSS, our case study focused on a bicycle sharing service. The central question was whether and how designers can be supported with a design tool, based on psychological ownership, to involve users in closing the loop activities. We developed a PSS design tool based on psychological ownership literature and implemented it in a range of design iterations. This resulted in ten design proposals and two implemented design interventions. To evaluate the design tool, 42 project members were interviewed about their design process. The design interventions were evaluated through site visits, an interview with the bicycle repairer responsible, and nine users of the bicycle service. We conclude that a psychological ownership-based design tool shows potential to contribute to closing the resource loop by allowing end users and service provider of PSS to collaborate on repair and maintenance activities. Our evaluation resulted in suggestions for revising the psychological ownership design tool, including adding ‘Giving Feedback’ to the list of affordances, prioritizing ‘Enabling’ and ‘Simplification’ over others and recognize a reciprocal relationship between service provider and service user when closing the loop activities.

This research focused on implement analysis to diagnose the viability to propose a design and repair strategy based on Product-Service System (PSS) and remanufacturing to preserve the value in white goods, more specifically laundry machines. The aim is to generate an alternative to the linear economy to redirect consumers to the circular economy, positively affecting the environment, the economy, and society, leading to responsible consumption. To achieve this, it is necessary to identify consumer behavior and the factors that intervene to buy remanufactured products. Also, find a timely methodology for the development of the PSS, analyze the ability to conserve added value, propose the strategy and verify its feasibility. The reach of this paper is establishing customer perception in the acceptance of remanufactured products in a circular economy model for white goods.

The building and construction industry, which is responsible for 39% of global carbon emissions, is far off track in achieving its net-zero emission targets. Product-service system (PSS) business models are one of the instruments used by the industry in the transition toward reaching these targets. A PSS business model is designed around an end-of-life solution that minimizes material usage and maximizes energy efficiency. It is provided to customers as a marketable set of products and services, jointly capable of fulfilling a customer’s needs. There are signals from practice however, that suggest that the implementation of this type of business model is falling behind. This study investigates this and seeks to identify key challenges and opportunities for sustainable PSS business models in the built environment. Using a grounded theory approach, data from 13 semi-structured interviews across five companies is used to identify challenges and opportunities that suppliers are facing in selling their products through PSS business models. Our preliminary data analysis points to nine challenges and opportunities for PSS business models. We discuss these in the context of the current economic transition toward a sustainable and circular built environment and provide suggestions for further research that could help to overcome resistance toward the implementation of PSS business models. The contribution of this research to researchers and practitioners is that it provides insights into the adoption of new business models in fragmented and competitive business environments.

De lunchlezing bestaat uit twee gedeeltes. In het eerste gedeelte zal Dirk ingaan op inzichten uit de literatuurstudie naar de gebruikerskant van Product Service Systemen (PSS) en state-of-the-art ontwerpaanpakken om milieu-impact uit dit gebruik te verkleinen. In het tweede gedeelte wordt ingegaan op de eerste inzichten uit de Case Study met en bij The Student Hotel. In deze veldstudie onderzoeken wij hoe het fiets-deelsysteem (daaronder verstaan wij de fiets zelf, de fietsenstalling en de uitleen-app) anders ontworpen kan worden, zodat gebruikers zorgvuldiger met de fietsen omgaan. Gewenste gevolgen zijn minder milieu-impact uit gebruik, lagere kosten en een positievere gebruikerservaring. Er is tussendoor en aan het einde van de lezing ruimte om vragen te stellen via de chat.

Product service systems (PSS) are an example of a novel business model billed as having the potential to significantly reduce the environmental burdens of production and consumption processes. However, despite widespread interest in PSS, consensus regarding their actual environmental impacts, particularly with regard to salient issues such as global warming, is lacking. Hence this paper explores existing research to investigate the state of the art regarding the climatic impacts of PSS, alongside the set of factors that influence climatic impacts. The paper comprises a systematic review of peer-reviewed academic literature, quantifying the extent to which different types of PSS have the capacity to reduce greenhouse gas emissions across multiple product categories. Our study shows that significant reductions in climatic emissions are possible, but PSS are in many cases associated with more modest reductions and, in some cases, increased emissions. Further, we observe no clear differences in climatic impacts according to the type of PSS model that is deployed. Rather, differences in climatic impact are influenced by factors such as production and design alongside use-phase impacts and contextual factors such as transportation and the energy mix. The study argues that further research is needed to establish a more robust baseline upon which to draw conclusions regarding the sources of climatic impacts, and outlines fruitful ways for companies to tackle the complexities of climatic emissions that are beyond their control.

Extending the lifespan of products can be approached in several ways. One promising way is to give users a greater sense of ownership of the products that are used. In the context of Product Service Systems (PSS), products are often used temporarily, shared with others, and offered through a technology-mediated environment. Not much is known about psychological ownership in this context. To evaluate psychological ownership affordances as an intermediate knowledge tool in the context of PSS, we started a case study focused on a bicycle sharing service of The Student Hotel (TSH). The central question was how a design approach, based on psychological ownership, can help to redesign the bicycle-service of TSH to contribute to extended lifespans of the bicycles. This resulted in ten exemplary designs as project outcomes and two implemented design interventions in a TSH branch. All project members and stakeholders (app supplier X-bike and Roetz-bikes mechanics) and students of Eindhoven University of Technology (TU/e) and Utrecht University of Applied Sciences (HU) (n=42) were interviewed on process efficiency, process quality and design quality at the end of the collaboration. We performed a qualitative analysis to identify when and how the team members applied the design tool, how these obstructed or supported the design process, and if the team members show shared understanding of the behavioral and/or social consequences of their decisions. The results show both top-down and bottom-up insights, leading to four suggestions for adapting the existing model as an intermediate knowledge tool: (1) being more goal-oriented, (2) consider a hierarchy of affordances, (3) consider to add a new affordance and (4) recognize a more active role of the service provider.

This article seeks to contribute to the literature on circular business model innovation in fashion retail. Our research question is which ‘model’—or combination of models—would be ideal as a business case crafting multiple value creation in small fashion retail. We focus on a qualitative, single in-depth case study—pop-up store KLEER—that we operated for a duration of three months in the Autumn of 2020. The shop served as a ‘testlab’ for action research to experiment with different business models around buying, swapping, and borrowing second-hand clothing. Adopting the Business Model Template (BMT) as a conceptual lens, we undertook a sensory ethnography which led to disclose three key strategies for circular business model innovation in fashion retail: Fashion-as-a-Service (F-a-a-S) instead of Product-as-a-Service (P-a-a-S) (1), Place-based value proposition (2) and Community as co-creator (3). Drawing on these findings, we reflect on ethnography in the context of a real pop-up store as methodological approach for business model experimentation. As a practical implication, we propose a tailor-made BMT for sustainable SME fashion retailers. Poldner K, Overdiek A, Evangelista A.

Closed loop or ‘circular’ production systems known as Circular Economy and Cradle to Cradle represent a unique opportunity to radically revise the currently wasteful system of production. One of the challenges of such systems is that circular products need to be both produced locally with minimum environmental footprint and simultaneously satisfy demand of global consumers. This article presents a literature review that describes the application of circular methodologies to education for sustainability, which has been slow to adopt circular systems to the curriculum. This article discusses how Bachelor and Master-level students apply their understanding of these frameworks to corporate case studies. Two assignment-related case studies are summarized, both of which analyze products that claim to be 'circular'. The students' research shows that the first case, which describes the impact of a hybrid material soda bottle, does not meet circularity criteria. The second case study, which describes products and applications of a mushroom-based material, is more sustainable. However, the students' research shows that the manufacturers have omitted transport from the environmental impact assessment and therefore the mushroom materials may not be as sustainable as the manufacturers claim. As these particular examples showed students how green advertising can be misleading, applying “ideal” circularity principles as part of experiential learning could strengthen the curriculum. Additionally, this article recommends that sustainable business curriculum should also focus on de-growth and steady-state economy, with these radical alternatives to production becoming a central focus of education of responsible citizens. https://doi.org/10.1016/j.jclepro.2019.02.005 LinkedIn: https://www.linkedin.com/in/helenkopnina/

This study evaluates the maximum theoretical exposure to radiofrequency (RF) electromag- netic fields (EMFs) from a Fifth-generation (5G) New Radio (NR) base station (BS) while using four commonly used mobile applications: YouTube for video streaming, WhatsApp for voice calls, Instagram for posting pictures and videos, and running a Video game. Three factors that might affect exposure, i.e., distance of the measurement positions from the BS, measurement time, and induced traffic, were examined. Exposure was assessed through both instantaneous and time-averaged extrapolated field strengths using the Maximum Power Extrapolation (MPE) method. The former was calculated for every measured SS-RSRP (Secondary Synchronization Reference Signal Received Power) power sample obtained with a sampling resolution of 1 second, whereas the latter was obtained using a 1-min moving average applied on the applications’ instantaneous extrapolated field strengths datasets. Regarding distance, two measurement positions (MPs) were selected: MP1 at 56 meters and MP2 at 170 meters. Next, considering the measurement time, all mobile application tests were initially set to run for 30 minutes at both MPs, whereas the video streaming test (YouTube) was run for an additional 150 minutes to investigate the temporal evolution of field strengths. Considering the traffic, throughput data vs. both instantaneous and time-averaged extrapolated field strengths were observed for all four mobile applications. In addition, at MP1, a 30-minute test without a User Equipment (UE) device was conducted to analyze exposure levels in the absence of induced traffic. The findings indicated that the estimated field strengths for mobile applications varied. It was observed that distance and time had a more significant impact than the volume of data traffic generated (throughput). Notably, the exposure levels in all tests were considerably lower than the public exposure thresholds set by the ICNIRP guidelines.INDEX TERMS 5G NR, C-band, human exposure assessment, mobile applications, traffic data, maximum extrapolation method, RF-EMF.
