“…More specifically, our study contributes to knowledge accumulation on the topic, since while a number of studies involved WMs, most of them did not provide quantitative environmental analyses, and even fewer based them on real consumers data (such as [29,30], and other studies mentioned in [63]). The same is found by this study on the role of refurbishment, which already received considerable attention in the literature as a circular economy strategy [22,64,65], and also specifically for WMs [66]. While several studies focused on product design [9,67], however, our study considers the potential of the current WM installed base to be cost-and environmentally effective with a refurbishment business model.…”

Investigating Business Potential and Users’ Acceptance of Circular Economy: A Survey and an Evaluation Model

Circular economy is gaining attention in business and society to advance sustainability. This paradigm is particularly relevant for energy-consuming products such as washing machines, where alternatives to linear economy such as pay-per-use and refurbishment are gaining ground. To succeed, these business models should achieve consensus and acceptance among users. However, little attention has been paid to customers’ interest for circular economy business models so far. This paper aims to compare the economic and environmental impacts of pay-per wash and refurbishment business models, while investigating the degree of users’ acceptance and factors influencing it. A survey has been designed to collect users’ data regarding washing machine consumption patterns and acceptance rates of the circular business models. An evaluation model was developed to assess the economic and environmental impacts of pay-per-wash and refurbishment against a traditional linear model, fed with data from 279 Italian households collected through the survey. Finally, logistic regressions were carried out to investigate the influence of different customer, product, and usage factors on the acceptance rates of the two circular business models. Results show that, on average, pay-per-wash business models and washing machine refurbishment can guarantee environmental savings. However, only refurbishment generates economic savings for users. Moreover, only around half of the users’ sample shows a positive degree of acceptance of such alternatives. Respondent age has been found as a significant factor influencing the interest towards a refurbishment model, while the washing machine failures experienced by users and the relevance of the environmental gains achievable influence the acceptance rate of pay-per-wash models. Thus, when offering pay-per-wash schemes, suppliers should emphasize the information on the environmental benefits of this alternative, and that with such models they take over the responsibility and costs for maintenance and repair. On the other hand, providers of refurbished products should target younger consumers, who are less affected by a bias against second-hand goods.

“…However, it is a matter of case-to-case as remanufacturing challenges are commonly company-specific (Lundmark et al, 2009). For example, on the one hand, the case study by Shahbazi et al (2021) showed automation as an enabler for flexible remanufacturing processes, given that products were designed for remanufacturing. On the other hand, Sakao and Sundin (2019) and Sundin et al (2020) exemplified successful cases of automated remanufacturing but also highlighted the inherent uncertainty of remanufacturing as a barrier to automation.…”

“…Another example is automated remanufacturing, as covered in Subchapter 4.1.1. Automation can be challenging but also, given the right circumstances, beneficial in terms of creating an efficient and effective process (Sakao and Sundin, 2019;Shahbazi et al, 2021).…”

Remanufacturing is an industrial process in which a core -a used, discarded, or broken product -is transformed into a product whose specification and condition are newlike. However, to this date, remanufacturing activities on the market are few in comparison to manufacturing. There are several types of remanufacturers; the least common type is the original equipment remanufacturer, an original equipment manufacturer that not only manufactures new products but also remanufactures cores of its own products. The potential for remanufacturing to become a more widely used industrial process for original equipment manufacturers is therefore high. Increased remanufacturing activities can positively contribute to the environment by transforming cores into a new-like condition instead of manufacturing new ones. The contribution comes from a reduction of raw material and energy consumption compared to manufacturing. Therefore, remanufacturing has the potential to decouple environmental impact from economic growth, thus contributing to more sustainable societies. However, assessing the benefits of remanufacturing does not directly correlate to growth within the remanufacturing industry. To encapsulate the environmental, social, and economic benefits of remanufacturing, manufacturers need to be aware of how remanufacturing can be initiated and implemented in practice with positive economic effects. The aim of this licentiate thesis, therefore is, to explore how original equipment manufacturers can initiate profitable remanufacturing.

“…Although users can make decisions based on previous experience, this type of decision-making method needs a long-term accumulation of experience. Accordingly, there is no guarantee to use the optimal configuration as the selected remanufacturing scheme [ 4 , 5 ]. Meanwhile, since the expenses of electronic control systems for remanufacturing are higher than one million yuan, bad decisions will lead to economic losses.…”

Remanufacturing an evaluation system for electrical control systems of drilling rig based on the improved FCE and ANN

The decision process of different remanufacturing schemes in an electronic control system has great fuzziness and uncertainty. Therefore, it is essential to use an appropriate method to show the characteristics of different schemes and support the users’ decision. Based on the concepts of the artificial neural network theory and the improved comprehensive evaluation method, the decision-making system of the electronic control remanufacturing scheme was constructed in the present study. In the first step, a classification method of parts is proposed from the perspective of manufacturing enterprises. Moreover, an artificial neural network model is used to determine parts of remanufacturing value. Then the pricing strategy is divided according to the users’ needs, and then a decision model is constructed. The combined subjective and objective methods are used to solve the compound weight of different equipment, and a set of improved fuzzy comprehensive decision methods is formed. Then the proposed model was applied to an electronic control transformation project as an example to evaluate the performance of different schemes. The evaluation results were consistent with the results of a third-party organization. It was concluded that the proposed scheme can be used as the theoretical basis to choose the best remanufacturing scheme to ensure the efficient operation of each part in an ECS.
