How- ever, the move towards CE requires managers and decision-makers to rethink and redesign their Business Models (BMs) incrementally or radically. In order to achieve proper decisions on resource usage, product designs, material flows, and recirculation of materials, data plays a significant role in CE. Accessible data is considered as an essential enabler of circular solutions and at the heart of circular business models. In this regard, digital transformation can offer innovative tools for efficient execution and sharing of data to help companies generating new business models and to increase their competitive advantages. This study explores different data-driven BMs enabled by digital tech- nologies in CE.

Therefore, innovat- ing Business Models (BMs) are the fundamentals of the CE concept (Centobelli et al., 2020). Bock- en and Ritala (2021) defined two strategic choices in developing circular BM initiatives as innovation and resource strategies. While resource strategy focuses on narrowing, slowing, closing, and regen- erating resource and energy loops (Geissdoerfer et al., 2018), innovation strategy focuses on firm- driven internal processes (closed innovation) and collaboration with external partners and stakehold- ers (open innovation). The value creation in circular BMs for narrowing the loops happens by delivering https://doi.org/10.54337/jbm.v11i1.7245 Journal of Business Models (2023), Vol. 11, No. 1, pp. 78-88 7979 value to customers through efficient design and production, reducing the extraction of virgin mate- rials and resources (Li et al., 2010). In slowing the loops, circular BMs aim to create value by extend- ing products’ life by designing products that can have more than one use cycle and are more dura- ble, upgraded, repairable, and easy to disassemble recyclable (Zhu et al., 2010). Finally, BMs for closing the loops generate value through recycling and re- covering materials for reuse in new production pro- cesses (Bocken and Ritala, 2021). Processes such as resource optimisation, manufacturing products, extending the lifetime of products, offering new use cycles, and improving material flow, include high- volume data, which, if implemented efficiently, can enhance circularity (Ingemarsdotter et al., 2020). Data can create value when transferred to informa- tion, which can be integrated with other data sourc- es and interpreted as knowledge. When knowledge is further enriched and developed, it forms wisdom (Kristoffersen et al., 2020). A data-driven CE gives companies more opportunities to develop innova- tive BMs, create networks and partnerships, as well as expanding ecosystems (Kauppila, 2022). Trans- parent data on material and components enables measuring the impact of production and opera- tions on material, creating pure and high-quality feedstock by preventing toxic, contaminant and non-renewable material, as well as reducing the cost of material extraction and usage (Blomsma et al., 2020). Hence, it helps companies to make more efficient and accurate decisions on material and process choices to achieve CE goals. In addition, accurate data on material flow internally and across the whole value chain can ensure proper recycling opportunities at the end of product’s life while en- hancing the recovery processes of materials (Sitra, 2021). Accordingly, data for circular BMs can be categorised as follows: data on product design and production, data on use phase and customer be- haviour, data on product and service lifetime, data on system performance, and data on material flows. Implementing such data in circular value creation develops BMs such as servitisation-based models, product as a service model, sharing economy mod- els, collaborative consumption models, product life extension models, and resource recovery models (Luoma et al., 2021). As shown in Figure. 1, data is at the core of the CE model, which can be collected, stored, measured and analysed by digital technologies such as big data, Artificial Intelligence (AI), Blockchain and the Internet of Things (IoT), also known as Industry 4.0 • Figure 1.

Digital technologies are rev- olutionising BMs in CE by: • enabling tracking and tracing products and materials to develop product-as-a-service sys- tem which reduces product ownership while increasing reuse, repair and refurbishment op- portunities (Alcayaga et al., 2019); • enabling data sharing within the whole supply chain that improves retaining of value from prod- ucts and materials (de Sousa Jabbour et al., 2019); • enabling higher efficiency and circularity in manufacturing products and material process- es (Ranta et al., 2021); • enabling platforms that connect companies and customers, support development of ser- vice and dematerialisation, and facilitate indus- trial symbiosis (Täuscher and Laudien, 2018); • enabling shared databases for sharing waste information and reusing waste as a resource (Radamaekers et al., 2011). Although research on the role of data in CE has re- cently gained the attention of practitioners and re- searchers (Luoma et al., 2021), only limited studies were conducted on the role of digital technologies in data-driven circular BMs (Ranta, 2021). Therefore, the research questions of this study are as follows: RQ1. What are the existing data-driven business models in CE? RQ2. What is the role of digital technologies in data-driven circular BMs? Methodological approach To answer the research question and to understand the existing literature on the role of digital technolo- gies on data-driven circular BMs, a systematic liter- ature review was conducted in this study (Xiao and Watson, 2019). Scopus and EBSCO Business Source Complete were the selected academic databases. The search was conducted using the main terms ‘circular business model’, ‘digitalization’, and ‘data- driven business model’. The set of keywords for each term was selected based on the domain literature (Table 1). The search terms were selected in the ti- tle, abstract, keywords, or subject, with ‘data’ chosen as any part of the text. In addition, the search was limited to articles and reviews published in peer-re- viewed journals, English language, between January 2000 and March 2022 (1.1.2000-31.03.2022). Table 1.

To ensure the final sample, the articles should 1) include the concepts of circular BMs and circular value creation, 2) address the digital tech- nologies and CE, 3) address the utilisation of data in circular BMs by digital technologies. Accordingly, the articles that did not meet these criteria were ex- cluded. Furthermore, the author read the full articles for a more accurate decision, specifically the results sections. The literature search process is shown in Figure 2, based on which 47 articles were selected for full article screening. After reading the full text of each article carefully, the irrelevant articles were excluded and resulted in 22 selected articles for a systematic review regarding the theoretical, con- ceptual and empirical contribution to answering the RQs of this study. Furthermore, the relevant data was collected man- ually and documented systematically in an Excel sheet. The aspects of the articles related to the role of data in circular BMs and value creation by digi- tal technologies were assessed and identified. The main terms of circular BMs, the definition of the BMs, the role of data in circular BMs and the descrip- tion of how digital technologies enable data for cir- cularity in these BMs were identified and coded after the data analysis. This way, the contents of articles were classified and compared to form a systematic finding. Results of the literature review The role of digital technologies as an enabler of cir- cular strategies, ReSOLVE strategies, and circular BMs has been discussed in various research and studies since 2017 (Alcayaga et al., 2019; Blomsma et al., 2020). However, according to the results of this study, the vital role of data, how data creates value in circular BMs through digital technologies, has only been argued by limited researchers since 2018. The results from the systematic literature review indi- cate the increasing trend in research on this topic, with three publications in 2018, two publications in 2019, three publications in 2020, seven publications in 2021, and seven publications by the Spring of 2022 (Figure 3). Moreover, the journals with the highest publications are respectively as follows: Sustainability open ac- cess Journal with six publications, four publications in Business Strategy and the Environment Journal, two publications in Journal of Cleaner Production and two publications in Journal of Resources, con- servation and Recycling, and the rest were pub- lished in various Journals (Figure 4). According to the results, as illustrated in Figure 5, IoT is the most discussed digital technologies in dif- ferent research due to the capability of IoT sensors and links in connecting physical products and online services. Therefore, it can enable tracking, tracing and transferring of real-time data, which results in saving resources, optimisation of processes, transportation and material flows, as well as mini- mizing unnecessary expenses on material extrac- tion throughout the entire network of supply chains (Ivanov et al., 2022; Chauhan et al., 2022; Ranta et al., 2021; Ingemarsdotter et al., 2020). Furthermore, Data-based services are a rising trend aiming at increasing transparency and creating new value from supply chain data. According to the re- sults, 13 publications discussed the “Product-service System (PSS)” BM in the concept of CE and highlight- ed the significant role of digital technologies, spe- cifically IoT.

Various authors emphasized the role of data in extending the life of products for creating value and developing service-based BMs. In this regard, data enables repair, reuse, maintenance services and re- cycling while helping companies to optimize product design. The second vital circular BM highlighted by the authors was “Blockchain-based supply chain”, with the important role of Blockchain technology in creating a transparent and trustable data transac- tion throughout the entire supply chain. Many au- thors mentioned that the tight connections between Blockchain and IoT sensors, create a trustworthy environment for different actors within the sup- ply chains and enable safe and visible transactions without the need for a third party. “Sharing Econo- my”, “Digital remanufacturing”, “Digital Recycling Ecosystem”, and “Pull demand-driven model” were respectively the most discussed circular BMs, high- lighting the role of digital platforms and cloud-based technologies. Table 2 below includes an overview of the data-driven BMs in CE identified through the lit- erature review. Discussions and Conclusions The findings of this paper offer a greater understand- ing of the role of data in CE and why data is crucial in developing circular BMs. The existing data-driven BMs have been identified and why data is important in circular BMs has been discussed through this re- search. Data is the source of value in various deci- sion-making processes in CE and enables material and process optimisation. Precise and accurate data supports the best choices and decisions in changing supply chains, ecosystems, and networks dynami- cally. The results from the systematic review show the increasing trends in this topic and the increas- ing potential for more emperical studies in future.

Main resilience strategies such as multi-sourcing, collabora- tion, visibility, and flexible re-routing. Viability is the ability of a supply chain to survive in a changing environ- ment through a redesign of structures and replanning of performance with long-term impacts. Data on each stage of product's life enhances transparency and visibil- ity in the supply chains which is highly important for efficiency, resilience and sustainability while tracing performances. Data from connected products, plants and sys- tems enables operation optimization and create better quality products. Tightly connected IoT sensors and platforms to Blockchain technol- ogy allow contracting in the platform context and creating improvements in performance through transferring real-time data, visibility and trust. Blockchain registers each transactions of products and materials throughout the value chain, thus ena- bling access and exchang- ing of reliable data without the need for third party operators. AI and big data analytics can enable visibility and outsourcing in pricing and revenue decisions.

Subramoniam et al., 2021, Kerin and Pham 2019 in supply chains, ecosystems and various value crea- tion strategies in CE with the focus on different in- dustries such as textile and fashion which have more complex supply chain. This research is limited to understanding the role of data and digital technologies in circular BMs. Hence, the study only examined the papers that included the term “data” and excluded articles that only fo- cused on digital circular BMs and not mentioned data utilization. Moreover, the concepts “circular BMs” and “digital technologies” are showing strong and fast development recently, especially from the data-driven perspectives. Future research will ben- efit from a comprehensive study on the role of data on different CE strategies, process and product designs. Moreover, a deeper understanding of the role of data as a driver of circular BM innovation and configuration, the role of data in enhancing collabo- rative ecosystems, and the role of data in creating and capturing value in the circular supply chain are required through studies of different cases. Finally, although the role of IoT has been identified consid- erable as an enabler of data-driven BMs in CE, there is still potential to explore the capabilities of AI, ana- lytics and blockchain technologies in this field.
