Assessing the Role of Big Data and the Internet of Things on the Transition to Circular Economy: Part II
An extension of the ReSOLVE framework proposal through a literature review
This paper presents the main findings of a literature-based study of circular economy (CE) extending the technology attributes present on the Ellen MacArthur Foundation (EMF) Regenerate, Share, Optimise, Loop, Virtualise and Exchange (ReSOLVE) framework. The introduction and methods were presented in Part I (1). Part II concludes that there are 39 capabilities grouped into six elementary CE principles and five action groups, with public administration being the most interested sector, forming the CE information technology (IT) capabilities framework. It is expected the framework can be used as a diagnostic tool to allow organisations to evaluate their technological gaps and plan their IT investments to support the transition to CE.
1. Results and Discussion
For this study, a complete set of scientific publications was analysed. Regional and temporal characteristics are presented in Figure 1 (from first publication to 2018; total of 226 documents, including articles, reviews, conference papers and proceedings, filtered according to remarks presented in the Methodology section of Part I (1)) and Table I. Europe and Asia lead the interest in the subject mostly due to the efforts and regulations established by the EU and China governments. North America (here including Mexico and other Central American countries), despite the high level of development of the geographies, occupies only the third place in publications, with less than 15% of participation. This number also draws attention to the fact the USA is one of the major environmental polluter countries according to the United States Environmental Protection Agency (US EPA) (2), which reveals a context of significant research opportunities for the region.
Considering all the publications, 53% came from scientific journals and 15 sources presented at least two publications on the subject. The Journal of Cleaner Production (ISSN 0959-6526) and Sustainability (ISSN 2071-1050) led with 19 and nine publications respectively, as shown in Appendix 1 (for all Appendices, see the Supplementary Information included with the online version of Part I (1)). The high number of other source documents (47%), along with the publication concentration in the past three years, may indicate science and academia are still in the early stages of development for the studied subjects.
The research also grouped publications according to the Standard Industrial Classification (SIC) codes (3). The majority of documents apply to public administration (32.3%), mostly because of smart city initiatives and suggests governments are leading initiatives and sponsoring research. A considerable number of publications (30.1%) were not allocated to a specific SIC code as they could not be related to any specific industry. Results are presented in Table II.
Documents were also grouped by methodology type, which demonstrates more interest in model development and reviews as shown in Figure 2. This indicates researchers have been putting more effort into standards, definitions, framework creation and reviews (which can be justified by the early stage of stability and maturity of the subjects). Other analysis was made according to CE principles (4) as demonstrated in Figure 3. The highest level of participation on the reduction principle suggests a major focus on changing consumer behaviour with the use of new technologies rather than investing in clean energy sources or extending product lifespans. On the other hand, the reclassification principle, despite its importance, still lacks technology efforts.
Supplementary details regarding mapped documents, such as top publishing institutions, journals and authors are available in Appendix 1.
In Appendix 8 we also present some practical case studies mapped during the literature review for distinct industries and countries in order to illustrate how CE can be fostered by big data and internet of things (IoT).
1.1 Content Analysis
Research extracted the 150 most frequent words from the 226-article text corpus in order to verify and confirm that the resulting capabilities list is addressing the most relevant topics. The word cloud generated is shown in Figure 4.
Bigram, trigram and four-gram generation proved to be a valuable insight resource as some compound expressions not only appeared in the top 150 list, but also performed as an important validation tool for capabilities generation (for example ‘cloud computing’, ‘energy consumption’ and ‘smart sustainable city’), all key aspects of the validated capabilities list.
The words ‘product’, ‘service’, ‘urban’ and ‘city’ all appeared with high frequency, indicating initiatives for different industry types can benefit from big data and IoT, for example, and therefore influenced the framework development (i.e. specific treatment for industry type). The same analysis was made for each expression, performing essentially as a verification tool to ensure the framework and capabilities were consistent.
1.2 Experts Review
The first version of the resulting capabilities framework was submitted to a group of domain experts who provided useful insights into the study. Table IV shows the main contributions accepted from the domain experts. Typographic errors, rephrasing, use of synonyms and other small revisions are not listed.
The list of domain experts is presented in Appendix 2.
|CE principle||Contribution||Contributing experta|
|Design||Clarification on urban areas relation to public administration only||3, 4|
|Added ISO 20400 - sustainable procurement (applies to reduction, reuse and recycle principles as well)||1|
|Reduction||Process postponing: inclusion of ‘no effectiveness loss’ condition||5|
|Decentralised offices: only if proven to provide more efficient use of available resources||4, 5|
|Added emissions monitoring||4|
|Reuse||Added marketplaces for sourcing, value and managing reusable materials||1|
|Recycle||Added disassembling and remanufacturing||4, 6|
|Policies application rather than only having the policies documented||1, 4|
|Use of electronic tags||1|
|Added recyclable resin||1|
|Renewable energy||Net metering added to list||4|
|Blockchain transactions added to list||2, 4|
1.3 CE IT Capabilities Framework
The final framework resulted in a set of 39 capabilities divided according to the six CE principles and presented in Figure 5 and Table V. It builds on both the ReSOLVE framework (5) and the six CE principles (4). The mapped capabilities were separated into application groups and industries, as some are considered technological tools, others new processes, some long-term projects and others punctual actions.
|CE principle||Big data or IoT capabilities||Sample sources|
||(7, 12, 13, 16–28)|
||(7, 9, 12, 13, 15–17, 25, 29–32)|
||(7, 9, 12, 13, 15–17, 25, 33)|
|Reclassification (RC)||(7, 34–36)|
|Renewable energy (RN)||
a Process of managing the entire production lifecycle from design, through engineering, manufacturing and ultimately service and usage
The mapping considering each capability and the corresponding block of the framework is presented in Figure 6. Capabilities not related to any industry are considered as applicable to any (cross industry).
1.3.1 Framework Highlights
The ReSOLVE Framework itself promotes a direct application of modern technologies on the elements ‘optimise’ (leverage big data and automation), ‘virtualise’ (dematerialisation) and ‘exchange’ (for example three-dimensional printing). With the establishment of the CE IT capabilities framework, not only can new applications be observed to those elements, but also it is now possible to notice that all elements of ReSOLVE can benefit from cutting-edge technologies. For example: the ‘regenerate’ element can be leveraged with net metering and the use of solar energy allows the use of IoT based devices in remote areas, like agricultural crops; the ‘share’ element benefits from smart connected devices monitoring equipment’s usage and providing predictive maintenance data and technology also connects users with similar interests allowing higher usage levels; in ‘optimise’, waste reduction can take many advantages from technology, varying from the use of AI and machine learning on product design to optimise resource consumption to application of green IT to increase product efficiency; ‘loop’ benefits from the use of AI to allow closing the loop on materials and to optimise waste collection and reverse logistics with IoT; ‘virtualise’ links directly with cloud computing and the home office; and ‘exchange’ may use technology on product design to promote shifting to renewable materials feedstock.
The scientific interest in applying modern technologies such as big data or IoT in the transition to CE is growing. Articles from 2017 and 2018 alone account for 66% of all the publications on the subject to date, reflecting what takes place in practice, given the number of cases and models identified – 60% of all articles mapped. Nevertheless, from the 21 different CE frameworks identified, only three mention IT as a component, and most of them refer to EMF as a primary CE reference, some built on EMF’s ReSOLVE framework. Therefore, IT scientists, scholars and practitioners still do not have at their disposal a framework to be followed that would allow a technological gaps assessment. This framework development was the article’s main purpose, which identified 39 IT capabilities necessary for organisations to consider themselves technologically circular.
The main scientific contribution of this study was the extension of the existing ReSOLVE framework to a level of detail that will allow IT professionals to assess their current CE gaps and plan their actions to enable an easier transition to CE. Additionally, the role modern technologies aligned with Industry 4.0 play in the organisational transition to CE was identified, and the status quo of related research around the world and the most interested institutions and publications were described.
In addition to the traditional literature review of 226 articles retrieved from Scopus® and Web of ScienceTM databases, the following triangulations were carried out to allow research confirmation and comprehensiveness: content analysis through statistical tool ‘R’, grey literature analysis and expert opinions. The capabilities were then divided according to the six CE principles presented in the literature: six for the design principle, 11 for reduction, 11 for reuse, seven for recycling, one for reclassification and three for renewable energies. The findings indicate that there are principles currently more susceptible to IT than others and that the public administration sector has attracted more research interest in the area possibly because of current initiatives fostered by government entities and agencies.
The following future research opportunities originate directly from this study: the conception of a scale with metrics to allow organisations to self-assess and benchmark (i.e. how many and which capabilities should an organisation implement and to what extent before it can be considered circular); and the confirmation of the framework’s performance by applying it in the form of a questionnaire or survey against selected organisations of different ports and industries.
The limitations of the study lie mainly in the volatility of recent modern technologies that may not have a long lifecycle, making the framework obsolete in the short term. In addition, since it is an essentially theoretical study based on published documentation, it still lacks practical confirmation through organisational case studies.
