“…The concepts generated using the outcomes of the industrial application of LFD were evaluated through a simulated LCA by manipulating the lifecycle data of the EO, based on the suggested conceptual design changes. The generated concepts for the RO were quite similar to the ones suggested and assessed by a previous study (Willskytt and Tillman, 2019) performed by two of the co-authors of Paper 3. Thus, the LCA data for the assessment of the new concepts were taken from this previous work and modified accordingly to simulate and assess the potential environmental impacts of the concepts for RO.…”

“…Subsequently, lifecycle data analysis was carried out, which provided quantitative insights into the environmental impacts of the same EO. This data was extracted from an earlier research work of two of the co-authors of Paper 3, who conducted a comprehensive LCA on the same product system (Willskytt and Tillman, 2019). The data collected from these sources were fed into Phase 0 of LFD by the authors and were converted into prioritized design requirements.…”

Cover conceptualized and designed by Shwetha VC and Abhijna Neramballi. The image of the brain represents the cognitive aspect of the research. While, the blue icons placed left of the brain represent the cognitive space of product design, the orange icons placed to the right of the brain represent the cognitive space of service design. The combination of the two cognitive spaces represents the cognitive space of product-service system design. The green icons of a magnifying glass and a compass arranged at the top of the brain represent descriptive and prescriptive dimensions of this research, respectively. The green icon of the hand with the sapling represents the practical implications of this research in terms of enhanced environmental performance of industrial activities.

The implementation of circular measures in businesses constitutes a solution to future resource scarcity, which has yet to gain momentum. To select and implement such measures, companies, with limited resources need practical and easy-to-use guides that help them understand the financial outcomes while leading them towards more circular solutions. To this end, a guideline based on Lifecycle Costing (LCC), which fulfils the aforementioned criteria, has been created. The guideline directs the companies towards measures at the top of the CE hierarchy and LCC is used to assess profitability and provide information on material circularity. Its development follows the Design Research Methodology (DRM) and is based on using LCC at three case companies when selecting circular measures and on literature. Insights on the companies' process and decision criteria as well as the LCC results are presented. One identified critical criterion is the profitability of a circular measure, but comparing the LCC of alternatives is only an adequate measure of profitability, if the alternatives are functionally equivalent and of equal value for the customer, otherwise revenue and customer costs need to be compared as well. In addition, because labour is included in LCC, by categorizing the costs companies can be guided towards exchanging material costs with labour costs. Concerning circularity, in this comparative context, the difference in material cost between the alternatives can be used to measure circularity performance without additional effort. Finally, customization of products was also identified in the company research as a barrier to the implementation of various circular measures.

“…Case-by-case decisions are necessary [28] for these types of products. Similarly, replacing single-use products, e.g., diapers and incontinence products, with more durable ones has also demonstrated both positive and negative results [18]. Passive durable products, however, hold a larger and more consistent potential for environmental improvement because their environmental impact is dominated by the production phase, usually the production of materials, while their physical lifetime is not fully exploited [20].…”

“…We propose that prolonging the lifetime of passive durable products through PSS could be such a solution because it is not as complex as other CE strategies, e.g., the creation of sharing platforms or constant administration of active product or completely redesigning the offering as advocated by result-oriented services. Furthermore, although the potential of a PSS to contribute to resource reduction is dubious both per unit and due to rebound effects [6], the extension of the lifetime of passive durable products, i.e., products that do not consume energy or materials during the use phase, has been found by researchers to have high potential [18][19][20]. The reason is that the majority of the environmental impacts occur during extraction of raw materials and production, and consequently, extending the lifetime of the product makes environmental sense (ibid.).…”

Is Prolonging the Lifetime of Passive Durable Products a Low-Hanging Fruit of a Circular Economy? A Multiple Case Study

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.
