1. Introduction
The vertical disintegration of companies has increased the complexity of management in terms of time and quality and increased uncertainty in the markets, making it impossible today for companies to compete effectively if they are isolated from their suppliers and other stakeholders
[1,2][1][2]. In this context, adopting the concept of supply chains (SCs) is increasingly essential for a company’s performance. Moreover, two themes are being increasingly discussed in the context of SCs, the circular economy (CE) and Industry 4.0 (I4.0)
[3]. The CE paradigm consists of a possible way to achieve environmental objectives and economic sustainability by developing systemic changes that go beyond the individual company and involve the other actors in the SC, contributing to adding value to a product and/or service
[4,5][4][5]. On the other hand, I4.0 refers to an industrial revolution based on the deployment of automation technologies and information and communication technologies, which can be helpful to meet current SC needs, such as flexibility, increased productivity, reducing waste, resource optimisation, and more sustainable production processes
[2]. Consequently, the CE can be used to minimise resource usage and decrease waste generation in a high-tech manufacturing environment, integrating sustainable resource management and transforming SCs in the I4.0
[6,7][6][7].
Previous research has assessed the relationship between these themes. For example, some researchers have linked the CE to I4.0
[7[7][8],
8], while others have linked, separately, the implementation of I4.0 or the CE to SC performance
[1,2,9,10,11][1][2][9][10][11]. However, a systematic analysis from the perspective of experts concerning the relationship between these three topics is still missing. Many articles do not provide insight into the realization of initiatives to introduce Sustainable Industry 4.0 in the supply chain context. Our paper uses combined Interpretive structural modelling (ISM) and the MICMAC approach was used as a systematic methodology to establish the interrelationships between these topics. However, there is still a lack of studies that analyse this relationship more deeply, to create a consensus between the relationships between the different strategies of I4.0 and CE in the supply chain
[12,13][12][13].
To clarify our research gap, Table 1 was developed to contrast the research gap wisth the study ies already published.
The discussion on sustai
nable developm
s to identify the relationsent and the CE has been highlighted worldwide since the 1980s, recognising that natural resources are limited and are suffering significant and irreversible damage from human activity [4]. Thi
s new persp
between I4.0 technologies and the CE andective has created pressure from several stakeholders (consumers, investors, governments, etc.) for companies to reduce their negative impact on the environment [4]. pThere
sent the effect of adopting both approaches concerning SCfore, organisations have been working on improving their environmental performance to obtain competitive advantages (such as increased market share and product differentiation) capable of improving financial performance
. Then, this researc without significantly increasing (or even reducing) costs [13]. At th
e is an attempt to fill this gap and aims to answer the two research questions: (1) what are thesame time, I4.0 has been impacting the development of the global industry as it has been providing solutions for computerisation and digitalisation. In other words, the CE and I4.0 are seen as having the potential to increase the efficiency and competitiveness of organisations and, consequently, to offer performance improvements for SCs. Sustainable development depends on its relationship
s between with technological development [14]. The I4.0

e potential effect of these constructs on SC performance? As a starting point, a syste linked to economic and technological development has led to changes in the types of production and consumption, making SCs increasingly dependent and unsustainable [4]. Growing ma
rket
ic literature review (SLR) was developed, resulting in 19 constructs. Subsequently, the interaction competitiveness, environmental changes, public pressure, and environmental legislation have generated the need for organizations to change their production systems’ operations to ensure the coexistence of industrial development and environmental protection [16]. For thes
e between these conchanges to occur, it is necessary to redefine the basic struct
s aure of SCs to include environmental issues [17]. As recommend
ed by the
strengCE literature [5], th
e of the driving and dependence power of this relfirst step of this change is to migrate from a linear SC to a closed-loop one. When SCs extend environmental concerns to their operations

Srivastava [18] (p

2. Theoretical Background
Al, organisat
hio
ugh much work has been done on sustainable SCs, the relationship between thens need to stop seeing environmental issues as external restrictions that impose limits, increase the costs of their operation, and reduce their competitiveness CE[19] and
SCs
still needs to be explored, especiallytart instead to see them as an opportunity to generate economic and financial gains [18], t

identifyving their performance [13]. To tach
e methods and tools thatieve this, several practices need to be adopted
across , including: circular projects; designing products and operations in the SC t
o support efficient CE adoption, enabling a “complete” transition from a linear to a circular SC due to its increased complexity [5].aking into account environmental protection and health throughout the product’s life cycle; reverse logistics (planning and controlling the flow of raw materials, inventories, and products from the point of consumption to the point of origin to recapture value or ensure proper disposal); recycling and remanufacturing operations; the recovery, reuse, and Ireformin
this context, I4.0 technologies can be of great value [2,7]g of products and packaging; waste management and minimisation; and the substitution of hazardous materials or processes with less problematic ones [20].
The S
C invo
me proposals for relationshiplves coordinating, planning, and controlling products and services through integrated activities between
these two approaches can be found insuppliers and customers. However, despite being connected, many of these activities are carried out independently by each member organisation of the chain [21]. Thus, the
literature, with ReSOLVE [16]results obtained in the traditional SC structure are no longer sufficient and do not match current technological bdevelopme
nts [21]. In thi

A dig

S

The intersection literatble and digitally integrated production systems; inter-organisational information integration, synchronisation and communication systems; worker support technologies; the Internet of Things (IoT); cloud computing; big data; and data analytics. Further, as Vacchi et al. [7] (p. 1) stated, “Indu

3. The Literature Regarding the Relationship between the CE and I4.0 and Its Effect on SC Performance
The need to optimise SCs due to the competitive pressures of the market promotes and encourages the adoption of I4.0 technologies
, in parallel with CE approaches
[15]. According to Rajput [24],
andthe SC performance. For this, the ISM approach was chosen to identify and classifyCE integration with I4.0 is a way to achieve sustainability, as it reduces barriers such as lack of information regarding the life cycle of products and uncertainty about the return on investments [25]. For

In other words, if organisations want (1)to identification of elements thamaintain and strengthen their competitive potential, they need to embrace technological and environmental changes together [12]. In this context

The following subsections describe these steps, as summarised in Figure 1ugh the theme’s relevance in the literature has been highlighted, no research was identified in the SLR assessing the relationship between the themes systematically from the perspective of experts.

4. Conclusions
The main contribution of this research is to present the relationships between the different constructs of the studied themes. The ISM model, the reachability matrix, and the strength matrix of relationships are, together, valuable tools for understanding the direction, order, and power of the complex relationships between I4.0, the CE, and SC performance. Using these tools, managers can make more proactive and consistent decisions regarding implementing I4.0 technologies and CE approaches. They can also select the main performance measures associated with this implementation, allowing the evaluation of the performance of projects with greater accuracy.
