this comprehensive concept extends well beyond a
narrow focus on environment, encompassing a
diverse range of factors that profoundly influence
fundamental structure of our food systems [30].
Fundamental essence of sustainability within food
industry is centred on three distinct yet closely
interconnected dimensions environmental, social,
and economic [59]. The mentioned aspects play a
crucial role in establishing a sustainable food system,
and it is essential to address them collectively to
achieve sustainability [60]. Food industry has a wide
range of considerations to make when maintaining
the sustainable path. It must deal with challenges of
lowering greenhouse gas emissions, minimising land
use, protecting biodiversity, managing water
resources, ensuring access to affordable food,
maintaining cultural relevance, and placing a priority

materials, utilisation of recyclable and biodegradable
materials, and minimization of waste [63].
The emergent rise of digitalisation through the
context of I4.0 enables manufacturing industries to
further advance the digital transformation within the
firm. It also allows future opportunities for
manufacturing firms to focus on performance while
having environmental impact. Although, the key
focus for firms is on product lifecycle that also was
evident through the existing studies within the
literature. Figure presents the provide value chain of
product and technology lifecycle model [64].
Figure 8. Value Chain of Product and Technology
Lifecycle [64]
Implementation of sustainable agricultural practises,
such as organic farming and reduction of pesticide
usage, helps promote well-being of soil and
preservation of biodiversity. Preservation of
biodiversity is of utmost importance, considering
significant influence that agriculture has on
traditional ecosystems. Incorporation of I4.0
capabilities serves to improve environmental
sustainability within food industry, utilisation of loT
sensors and analytics in resource management
enables a data-driven approach that enhances
allocation of resources and minimises wastage [22].
Implementation of I4.0 technologies, such as drones
and smart farming equipment, has been observed to
enhance precision agriculture and optimise resource
utilisation [19]. While implementation of automation
and robotics technologies has been shown to improve
operational efficiency and mitigate waste [65].
Utilisation of additive manufacturing facilitates
creation of customised and environmentally
sustainable packaging solutions [66]. Provision of
supply chain transparency enables consumers to
make well-informed choices regarding sustainable
products [12]. Integration of se technological
advancements, in conjunction with implementation
of sustainable practises, serves to foster a heightened
environmental awareness and enhanced resilience
within food industry. This approach aims to achieve
an ideal balance between technological innovation
and ecological management.
2.5.3 Economic Sustainability
Economic sustainability within food industry is an
important basis that supports financial stability and
long-term sustainability of businesses involved in
different aspects of food production, processing, and
distribution. At its essence, concept of profitability
arises as a crucial factor in ensuring economic
sustainability. Concept holds significance beyond
just financial revenues, as it encompasses core values
of businesses, guaranteeing their capacity for
investment, grow, and establish long- lasting
sustainability [7]. Mentioned concept can be seen in
practise of ensuring fair distribution of profits, which
is observed across all stages of supply chain. This
approach places significant emphasis on principle of
distributing rewards in a manner that is shared among
all relevant stakeholders. This ensures that all parties
involved, ranging from initial producers to final
distributors, are provided with a just and ethical share
of economic advantages [13].
Overall well-being of employees represents an
additional fundamental aspect of economic
sustainability, encompassing essential elements such
as equitable remuneration, secure industrial
environments, and availability of social welfare
programmes. The importance of health of people
involved in industry has a direct impact on
productivity and efficiency of workforce, thereby
contributing to a content and healthy work
environment [67].
An industry that prioritises economic
sustainability does not limit its dedication to this
aspect alone. This highlights importance of market
entry for small-scale and local producers, thereby
promoting their financial stability while advocating
for fair opportunities within industry. The effective
use of I4.0 capabilities has potential to enhance
economic sustainability within food industry through
a range of methods. To begin with, it is important to
note that implementation of I4.0 technologies has
potential to optimise utilisation of resources,
resulting in a reduction in production costs and an
overall improvement in profitability [3]. Also,

implementation of smart supply chains guided by
principles of I4.0 has been shown to enhance
operational efficiency, minimise resource wastage,
and facilitate market entry, thereby making a
significant contribution to achievement of economic
sustainability [68,9]. In addition, utilisation of
blockchain technology and data analytics facilitates
establishment of transparent and traceable supply
chains, thereby promoting equitable trade practises
and just pricing mechanisms for producers operating
on a smaller scale [69]. Furthermore, implementation
of automation and robotics in context of Industry 4.0
leads to a decrease in tasks that require significant
human labour, resulting in enhanced efficiency and
productivity in workforce, all while prioritising
welfare of workers [11]. Utilisation of I4.0
technologies has enabled small-scale and local food
producers to enhance their market reach through
digital platforms and e-commerce.
2.5.4 Social Sustainability
In the challenging world of sustainability within food
industry, social sustainability plays a significant role
in preserving wellbeing of people and communities
involved in food production and consumption. Main
goal is to make sure that industrial activities benefit
society while also preserving welfare and way of life
of individuals and communities. There are numerous
factors and tactics that work together to promote
social transformation and strengthen sustainability
principles in the context of I4.0 era and goal of
sustainable innovation.
Figure 9. Components and Dynamics of Corporate
Social Sustainability and Innovation [70]
A primary area of emphasis within suburban
communities revolves around enhancing public
consciousness regarding significance of food
sustainability. Utilisation of I4.0 technologies
presents a robust method for effectively spreading
this awareness, by capitalising on digital platforms
and communication channels to instruct and involve
public in sustainable food practises [71]. Essence of
social sustainability lies in establishment of
collaborative cooperation, which has been greatly
facilitated by emergence of I4.0. This development
has effectively promoted collaboration among a wide
range of stakeholders, encompassing government
agencies, corporations within food industry,
academic institutions, and local communities. As a
collective, individuals possess capacity to participate
in decision-making processes related to programmes
designed to promote empowerment and social
initiatives. The integration of data, analytics, and
digital platforms enables the implementation of data-
centric decision-making processes, thereby
facilitating the development of programmes that are
more effective and equitable. Consequently, this
encourages positive results for society [32].
Regardless of whether they are involved in Business-
to-Business (B2B) or Business-to-Consumer (B2C)
transactions, companies operating in the food
industry are increasingly incorporating sustainability
discourse into their social media communications.
B2B enterprises place a high level of importance
on well-being of their employees, whereas B2C
companies adopt a more balanced approach that
considers both economic and social dimensions.
Utilisation of I4.0 technologies has a substantial
impact on improvement of communication
endeavours, facilitating efficient engagements with
consumers and stakeholders [72]. Incorporation of
technological capacities, such as communication
infrastructure and logistic optimisation, holds
significant importance in improving sustainability of
supply chains within food industry entities [73].
Moreover, capabilities of I4.0 have potential to
greatly enhance social sustainability within food
industry. Implementation of automation and robotics
technologies has resulted in a decrease requirement
for labour-intensive and physically demanding tasks,
thereby improving safety and well-being of workers
[74]. Implementation of I4.0 technologies, such as
blockchain and data analytics, serves to establish
supply chains that are characterised by transparency.
This transparency, in turn plays a crucial role in
ensuring equitable compensation for small-scale
producers and workers [75]. Utilisation of digital
platforms and availability of real-time data offer
enhanced opportunities for individuals to access
information, thereby enabling consumers to make
well-informed decisions regarding ethically
produced food products [76]. Development of I4.0
has been instrumental in promoting enhanced

interaction between food producers and local
communities, thereby cultivating favourable
associations and encouraging social accountability
[75]. Furthermore, additive manufacturing plays a
crucial role in facilitating creation of culturally
significant food products and packaging, thereby
contributing to preservation and continuation of
traditional recipes [77].
2.6 I4.0 Components Application in Food Sector
2.6.1 Internet of Things (loT)
The concept of interconnectivity, a fundamental
principle of I4.0, serves as a crucial element in
establishing real-time connections between
machines, devices, and systems within complex
network of food supply chain. This principle goes
beyond simple technological integration and has a
significant influence on fundamental structure of
food industry. It coordinates an effective blend of
operational optimisation and sustainability
improvement. loT is a key component of I4.0
initiatives and is emerging as fundamental
infrastructure supporting intelligent manufacturing
and distribution systems [78].
Figure 10. Taxonomy of IoT Applications [79]
In context of food industry, loT plays a crucial role in
facilitating connectivity by utilising sensors to
effectively collect data related to factors such as
temperature, humidity, and state of products [78].
Real-time exchange of data in this system enables
stakeholders to make proactive decisions, which in
turn reduces spoilage, waste and ensures preservation
of product quality [80]. The importance of
interconnectivity is evident in its ability to facilitate
smooth coordination in field of food production,
enabling flexible adaptations, production processes
and adoption of just-in-time restocking approaches.
As a result, continuing problems of bottlenecks and
overstocking are reduced, thereby promoting an
environment advantageous to smooth operational
processes [81]. Possibilities of loT are not limited to
production alone, but also encompass consumer
engagement by leveraging smart packaging and
labels. By providing consumers with information
about origin, freshness, and sustainability of
products, these innovative approaches increase
consumer trust and enable informed decision-making
[11]. Furthermore, many different and numerous
contributions of loT extend beyond boundaries of
simple operational efficiency. Advancement of
sustainability is facilitated through optimisation of
operations, reduction of waste, improvement of
transportation and logistics, minimization of energy
usage, and enhancement of overall resource
efficiency [82]. Also, it provides substantial backing
for ethical and sustainable sourcing practises by
providing stakeholders with a transparent view of
complexities involved in supply chains.
2.6.2 Big Data and Analytics
Within framework of I4.0, combination of data
analytics and big data takes a crucial position,
coordinating a comprehensive process encompassing
data collection, storage, processing, and generation
of transformative insights. Integration of various
technologies plays a crucial role in supporting data-
centric ideology of I4.0, which forms foundation for
all aspects of food supply chain. I4.0 represents an
evolution in data collection techniques. By
employing a complex network of sensors and
interconnected systems, it coordinates collection of
extensive and diverse datasets at different stages of
food supply chain [83,84].
Figure 11. Characteristics of Big Data [85]
Mentioned data streams flow into secure databases,
frequently residing within cloud-based platforms, to
guarantee their availability for subsequent analysis
[86]. Within realm of data analytics, concept of I4.0

algorithms, to effectively analyse and evaluate
extensive volumes of accumulated data. To get raw
data ready for its upcoming role as an informant for
decision-makers, this analytical engages in dynamic
activities like data cleansing, collection, and
organising [87]. The impact of data analytics extends
to domain of quality control and system described in
text serves as a real-time monitor for ensuring quality
of food products. Equipped with capability to identify
irregularities and variations during each step of
production, it effectively prevents distribution of
inadequate items in market [88]. The field of data
analytics has given rise to concept of predictive
maintenance, which involves utilising sensor data to
proactively anticipate and prevent machine failures.
Implementation of strategic insight enables timely
maintenance of systems, thereby preventing
disruptive breakdowns in supply chain and
developing an environment characterised by
reliability and consistency [87]. Within context of
sustainable innovation in I4.0, data analytics plays a
key role, encompassing various aspects of food
supply chain. The phenomenon serves as driving
force for waste reduction, resource optimisation,
informed decision-making for sustainable packaging,
evaluation of supply chain sustainability, exploration
of consumer behaviour. It provides valuable insights
that guide sustainable marketing and product design
strategies towards a more sustainable future.
2.6.3 Automation and Robotics
Automation and robotics play a crucial role in context
of I4.0, offering considerable advantages across
various industries, including food sector, which
experiences significant benefits. Automation in food
industry refers to effective incorporation of
machinery, robotics, and control systems to carry out
a diverse range of activities, including but not limited
to packaging, labelling, sorting, and food production
functions [89].
Figure 12. Automation and Robotics in
Manufacturing
The distinguishing characteristic of robotics and
automated systems lies in their consistent precision,
which makes them exceptional in terms of accuracy
and product quality [90]. Consequently, they enable
efficient completion of tasks that require significant
labour, thereby reducing need for human
involvement and resulting in cost savings [91]. The
systems demonstrate their versatility by being easily
scalable to meet production requirements thereby
serving as a flexible solution for dynamic demands of
food industry [92].
In addition to their ability to achieve high levels of
accuracy, automation and robotics play a crucial role
in collection of real-time data, which offers a
valuable dataset for quality control, process
optimisation, and prediction of maintenance
requirements [93]. Automation and robotics are in
accordance with principles of sustainable innovation.
They have a significant impact on reducing food
waste, maximising efficient use of resources,
advocating for sustainable packaging methods,
improving food safety regulations, and strengthening
traceability throughout food supply network.
2.6.4 Cyber-Physical Systems (CPS)
Cyber-Physical Systems (CPS) have emerged as a
breakthrough integration of physical operations with
digital control and communication in food industry,
enabling real-time monitoring and control
capabilities throughout every aspect of food supply
chain [94]. These systems depend on a complex
system of sensors that are specifically engineered to
collect and transmit data related to crucial parameters
such as temperature, humidity, and pressure.
Figure 13. Physical and Digital World Connection [96]
A key feature of CPS is its ability to integrate and
analyse data in real-time, providing a comprehensive
perspective on entire production and distribution
processes [95]. Utilising extensive dataset available,
CPS systems have capability to make instantaneous
decisions and take actions, such as changing cooling

systems or adjusting conveyor speeds, to establish an
optimised operational setting. In addition, CPS
systems utilise predictive analytics to anticipate
potential problems and take proactive measures to
mitigate them before they develop [14]. Within food
industry, applications of CPS are diverse and
encompass various aspects. These include but are not
limited to temperature and humidity control,
monitoring food safety, optimising resource
efficiency, ensuring quality control, and enabling
traceability. These applications play a crucial role in
advancement of sustainability, reduction of waste,
and guarantee of consistent quality and safety
standards for food products [97].
2.6.5 Additive Manufacturing (AM)
Additive Manufacturing (AM), also referred to as 3D
printing, is an innovative manufacturing method that
fabricates real-world products by sequentially
depositing material layers based on digital 3D
models. In context of food packaging, AM emerges
as a significant contributor in reduction of waste and
promotes sustainability. In the foundation, AM
demonstrates exceptional proficiency in area of
customization. Utilisation of this technology enables
exact customization of packaging for individual
products, considering their distinct shape and size. As
a result, amount of excess packaging material is
minimised, representing a significant advancement in
waste reduction [98].
Figure 14. Traditional Vs. Additive Methods [99]
In addition to offering customization options, AM
provides capability to create packaging designs that
possess desirable qualities of being lightweight and
robust. This trend not only results in a reduction in
overall weight of packages, but it also contributes to
a decrease in transportation costs and emissions.
These outcomes correlate with fundamental
principles of sustainable packaging [100]. AM also
promotes towards ideal of minimal waste. The
utilisation of minimal materials in design process
leads to a significant reduction in waste generation,
thereby eliminating requirement for extensive
removal of materials during post-production [101].
Furthermore, utilisation of technology enables
exploration of innovative packaging configurations.
Mentioned designs effectively maximise strength,
insulation, and protection, thereby minimising use of
materials. This significant achievement greatly
contributes to development of sustainable food
packaging [102]. Benefits of AM are enhanced by its
use for short production runs and quicker
development. This capability facilitates the
production of goods as needed and in specific
locations, thereby diminishing need for extensive,
centralised manufacturing plants and promoting
sustainable practises [103]. Subsequently it is
important to acknowledge that AM has capability to
utilise biodegradable and environmentally friendly
materials for the purpose of food packaging. This
aligns perfectly with larger sustainability objectives
and represents a significant advancement in
advancing development of packaging solutions that
are environmentally safe.
2.7 Industry 4.0 and Sustainable Innovation
The incorporation of 14.0 technologies by food
industry has resulted in increased production
efficiency, enhanced quality control, and
establishment of a reliable traceability system [104].
Furthermore, these technologies have made
substantial contributions towards reduction of waste
and enhancement of overall productivity [3]. Prior
studies have utilised various methodological
strategies, such as comprehensive case studies and
surveys, to comprehend adoption trends and
consequences of specific I4.0 technologies within
food industry [21,9]. A notable development that has
arisen is growing significance of loT within food
industry, facilitating collection of real-time data and
facilitating smooth communication throughout
supply chain [11]. Several technologies have
undergone study in recent times, including utilisation
of loT for monitoring supply chains, application of
data analytics for predicting demand, and the
implementation of automation and robotics to
enhance food production processes. Previous
research efforts have played a crucial role in shedding
light on complex and diverse nature of sustainable
innovation in food industry. These studies have
conducted a thorough investigation that encompasses
all aspects of food production, processing,
distribution, and consumption [40].

Figure 15. I4.0 and Sustainability Functions [105]
The research methodologies utilised in these
investigations have exhibited significant diversity,
including quantitative assessments that examine
complex nature of environmental impact and
comprehensive case studies that analyse specific
examples of sustainable food production processes
[20,6]. The exploration of underlying factors that
drive sustainable innovation in food industry has
been a recurring and significant focus in this
research. These investigations have provided insight
into various factors that drive industry towards
sustainability. These factors include regulatory
requirements, increasing consumer demand for
environmentally friendly products, and industry's
strong need to reduce environmental impact of food
production. Understanding complex nature of these
driving forces is crucial, as they form fundamental
basis of the food industry's shift towards
sustainability [10]. These forces govern industry's
operations and significantly influence decisions
made by both producers and consumers.
2.8 Research Gaps
The current state of literature on I4.0 potential to
support sustainable innovation in food industry
reveals an apparent lack in thorough analysis of 14.0
technologies that have enormous potential in this
context. Additive manufacturing, also known as 3D
printing, has potential to greatly reduce food waste,
particularly in area of packaging. However, it is
interesting to note that this technology has received
relatively little attention in existing research efforts
[104]. Within wider framework of sustainability in
food industry, there is a significant focus on aspects
such as sustainable sourcing strategies and innovative
production techniques, both of which are clearly of
greatest significance. The often ignored but
profoundly important environmental factors that
cross complex landscape of food supply chain,
however, stand out as a noticeable gap in this wide
domain. The review of factors such as temperature
and humidity, which undoubtedly have a significant
impact on maintaining safety and quality of food
products, presents itself as a subject that warrants
more extensive and thorough investigation [15]. To
address current lack of research in this area, it is
necessary to conduct a comprehensive investigation
into technologies associated with Industry 4.0. This
will shed light on the less visible aspects of these
technologies, which may play a crucial role in
promoting sustainability within food industry [32].
The current gaps in academic research related to
Industry 4.0 and its impact for sustainability within
food industry provide an important barrier to
obtaining a thorough understanding of how these
technologies can be optimally utilised to advance
sustainability endeavours [25]. Knowledge gaps in
question are characterised by their diverse nature, as
they encompass various critical dimensions. First and
foremost, it is evident that there is a significant lack
of thorough investigation into specific technologies
associated with I4.0, which have capacity to greatly
contribute to sustainable innovation within food
industry. Considerable research has been dedicated to
concept of I4.0 in a comprehensive manner.
However, specific technologies that have potential to
significantly contribute to sustainability have not
been given appropriate level of attention they deserve
[128]. A few examples application refers to additive
manufacturing, commonly referred to as 3D printing,
and its relatively unexplored potential in mitigating
food waste derived from packaging [28].
Furthermore, there exists a noticeable gap in
addressing essential environmental factors within
food supply chain, in addition to limited examination
of specific technologies. Frequently, conversations
pertaining to sustainability within food industry
revolve around examination of sourcing practises and
production methods. Although those mentioned
variables undoubtedly hold significant importance in
sustainability initiatives, there appears to be a
noticeable gap concerning environmental
circumstances within supply chain. The control of
temperature and humidity is crucial for maintaining
quality and safety of food [106].
However, there is a lack of research on this topic.
Industry's failure to adequately investigate and
understand precise capabilities of 14.0 technologies,
coupled with its lack of concern for crucial
environmental factors, could hamper its ability to
fully exploit potential of these innovations in its
sustainability endeavours. Therefore, it is crucial to
address these flaws. The research endeavours to
broaden its scope by addressing an additional

overlooked aspect of sustainability in food industry,
specifically emphasising environmental factors
present in supply chain. These insights possess not
only theoretical value but are also expected to
provide industry stakeholders, such as decision-
makers and producers, with practical tools and
knowledge to improve their sustainability and
innovation practises.
3 Methodology
The scientific method used to examine and evaluate
Industry 4.0's potential for sustainable innovation in
food sector is described in methodology section of
this study. This chapter encompasses a
comprehensive integration of multiple components
that comprise research process, encompassing
research philosophy, research approach, Reliability
and Validity, data collection, data analysis, ethical
consideration and time horizon.
3.1 Research Process
The most important part of this study centres on the
examination of practical applications of Industry 4.0
in food industry, with a specific focus on
sustainability goals such as mitigation of food waste
resulting in improved energy efficiency. Although
there is a significant amount of research focused on
application of I4.0 across different sectors, there is a
noticeable gap in comprehensive analysis of its
specific implications for sustainability in food
industry. The main objective of this study is to gather
knowledge from various sectors within food industry,
to enhance our comprehension of potential of I4.0 in
promoting sustainable innovation. Additionally, this
research seeks to tackle pressing concerns like food
waste and energy conservation. As highlighted
earlier, there is a noticeable research gap that
underlines need to investigate utilisation of I4.0
capabilities in promoting sustainable innovation
within food industry. The study is to gather data
regarding sustainable practises available in food
industry.
However, it also examines wider implications of
I4.0 capabilities in relation to sustainable endeavours.
Several factors, including limited availability of
resources, challenges in accessing desired data
sources, and imperative to complete the research
within a specified timeframe. The adoption of
secondary data analysis is viewed as an appropriate
strategy to ensure advancement and successful
completion of study. Although primary data
collection was initially favoured, constraints forced a
greater focus on utilising secondary data.
3.2 Research Approach
Every scientific study must carefully consider its
research approach because it will determine study's
methodology and impact entire research process
[107] propose that there are two fundamental
research approaches. The deductive approach is
characterised by its emphasis on the relationship
between theory and research. In this approach,
existing theories serve as foundation for the research
process, ultimately leading to creation of ideas.

The study is conducted by researcher with aim of
either supporting or denying hypotheses. The second
approach can be characterised as inductive, as it
involves deriving conclusions based on empirical
observations. This method guides researchers in
formulation of new theories and hypotheses [107,
108]. Nevertheless, it is essential to acknowledge that
attaining absolute certainty is never achievable when
drawing inductive inferences. In practical
application, boundary between these two approaches
is frequently less obvious than described in the
existing body of methodology literature. According
to [107], although deductive methods are commonly
linked to quantitative data and inductive methods to
qualitative data, it is important to note that a
deductive approach can also incorporate qualitative
data. Within the context of research, chosen research
approach primarily adheres to an inductive

methodology. This decision is based on the extensive
utilisation of qualitative data and the exploration of
innovative theories related to the food industry.
However, it also utilises established theories to attain
sustainability within the food industry through the
implementation of I4.0. The research exhibits a
fundamental aspect of deductive logic, as can be
observed.
The qualitative approach effectively highlights
individual perspectives and complies with the idea
that reality is socially constructed. These are essential
elements in the analysis of real-life experiences and
perspectives that are inherent in secondary data.
Therefore, qualitative research is preferred
methodology for conducting a thorough investigation
into the practical implications of I4.0 in the food
manufacturing sector, as it offers the required depth
and breadth necessary for this study.
3.3 Reliability and Validity
In context of qualitative research, concepts of
reliability and validity hold significant importance as
they contribute to credibility and objectivity of study.
These concepts function as evaluative tools that
measure degree of reliability within research
methodology [109] proposed a categorization of
reliability and validity into internal and external
dimensions. Internal reliability refers to level of
understanding among multiple researchers within a
study group with regards to their observations. It is
essential that these researchers achieve an
understanding regarding their perceptions and
observations throughout course of their research
[109]. The presence of internal reliability within
study's findings ensures their reliability and
consistency. In order strengthen internal reliability of
this study, this chapter provides a comprehensive
account of data collection process. This level of detail
allows for other researchers to replicate study under
similar circumstances and achieve comparable
outcomes [110].
In contrast, external reliability pertains to degree
of which a study can be replicated and yield
consistent findings when compared to initial
investigation. Attaining a high level of external
reliability can present difficulties due to potential
variability in real-world conditions between initial
research and any subsequent replicating efforts.
However, [111] had proposed a strategy that suggests
assuming an identical position to initial researcher to
ensure replication of initial study. Internal validity
refers to degree to which researchers can achieve
agreement and arrive at comparable conclusions. The
degree of correspondence between observations
made by researchers and theoretical concepts
formulated during course of study is indicative of
measure of alignment. The utilisation of qualitative
research methods, characterised by an extended
period of engagement within social context, often
results in a strong alignment between observed
phenomena and theoretical constructs. Instead, this
study will rely on existing data collected by other
researchers to derive opinions and draw conclusions
about diverse purchasing practises.
3.4 Data Collection and Analysis
The initial study is based on an extensive theoretical
framework that has been specifically designed to suit
unique circumstances of food industry within context
of I4.0. To establish framework, a comprehensive
review of secondary literature relevant to research
topic was conducted, providing valuable insights into
field of study. The utilisation of secondary data
sources, such as academic books, scholarly articles,
reputable websites, and company reports, formed
initial phase in establishing parameters of this
research and identifying variables of interest for
thorough examination [112]. It is crucial to
acknowledge that implementation of Industry 4.0
technologies in food industry is a developing field.
Although secondary data gathered may have
originated in previous years, it still serves as a
reliable basis for this study, enabling us to expand
upon accumulated knowledge [107]. By adopting a
comprehensive theoretical framework, we can
systematically examine extensive relationship
between capabilities of Industry 4.0 and promotion of
sustainable innovation within ever-changing context
of food industry.
The methodological approach analyses
secondary data that is currently available,
emphasising resource efficiency, waste reduction,
environmental impact, and real-world applications of
Industry 4.0 in food manufacturing industry. Our data
analysis methods in this qualitative study are
specifically designed to systematically uncover
insights and patterns that align with our research
objectives. The main data source utilised in this study
consists of pre-existing secondary sources, which
include academic literature, reports, and associated
materials [107,113]. The process begins with data
familiarisation, wherein we engage in a
comprehensive examination of gathered secondary
data, aiming to acquire an in-depth understanding of
its substance and specific context. Following this,
coding phase, wherein systematically classify data,
identify significant segments, and assign codes that
clearly convey essence of each segment.

three essential parts, thoroughly investigates how
I4.0 technology and sustainable innovation meet in
the food sector. The Literature Review explores a
carefully chosen range of academic papers,
concentrating on the incorporation and effects of I4.0
in food production and sustainable supply chain
management. After that, the Thematic Analysis
carefully selects and explains major themes, offering
insights into technical developments, obstacles, and
social and economic ramifications. The last section,
the Discussion, critically assesses these topics,
particularly on evolving practices, trends in
technology uptake, and the consequences for
sustainability. This analytical trip provides a
comprehensive grasp of how I4.0 transforms the food
business to adopt sustainable practices.
4.1 Focused Literature Analysis
To guarantee the quality and relevance of article
compiled and reviewed, a rigorous selection
procedure that followed predetermined inclusion and
exclusion criteria was part of the literature review
approach for secondary data. Articles that addressed
sustainability and Industry 4.0 applications in food
business and were published between 2019-2024 met
the inclusion criteria. Publications published outside
designated time frame, articles not in English, and
articles not directly relevant to food business were
excluded. Using keywords like "Industry 4.0,"
"sustainable innovation," and "food industry," the
search approach involves querying academic sites,
including Scopus, WoS, and others. Many potential
articles were found in the first search, then carefully
examined for relevance to the topic and abstracts.
This resulted in the selection of five significant
publications, which together offer a variety of
viewpoints and conclusions about the contribution of
I4.0 to improving sustainability in the food business.
The essential themes, innovations, difficulties, and
consequences for sustainable practices were then
carefully extracted from each piece, serving as the
foundation for the ensuing thematic analysis.
4.2 Insight from Existing Literature
Quiroz-Flores et al. (2023) extensively reviewed 436
papers, emphasizing the implications and uses of
I4.0 technologies in food supply chains (FSCs). Their
findings demonstrate the importance of technologies
like blockchain and the Internet of Things (loT) to
improve FSCs1 transparency, trackability, process
optimization, and waste reduction. While some
technologies, such as blockchain and loT, have a
more significant influence than others, the study
classifies significance of numerous Industry 4.0 tools
in enhancing sustainability. It highlights those that
are still underutilized in food industry. This study
highlights the necessity for a balanced approach to
technology adoption for sustainable innovation and
sheds light on the current technological trends in the
food I4.0. Studies [52]3) examines the relationship
between business innovations and sustainability.
They define different sorts of innovations, such as
process, product, and I4.0 model innovations, and
discuss how these relate to triple-bottom-line
sustainability and the Sustainable Development
Goals (SDGs). Although process and product
innovations receive much attention, literature review
shows that open and marketing innovations require
more investigation [52].

4.6 Discussions
4.6.1 Changing Practices
Sustainability has been made considerably possible
by the revolutionary changes in food sector
production, distribution, and other practices brought
about by adopting Industry 4.0 technologies. One
significant development noted is the move toward
more sustainable and effective production
techniques. Blockchain and other loT technologies
can improve food supply chains, traceability, and
waste reduction, according to [46,117]. This
production modification ensures food safety reduces
environmental impact, and boosts resource
efficiency. Nestle has advanced product development
using I4.0 technologies. Since 2016, the corporation
has developed 60% faster, tested, and launched 12%
more technologies between 2020 and 2021. Nestle
reimagines core 47 brands, optimizes its portfolio,
and uses innovative approaches [121]. Technology
has expanded business models and customer
satisfaction for corporations. The Open Channel
platform promotes internal crowdsourcing and
innovation [121]. This method follows Industry 4.0
concepts of rapid, technology-driven development
and customer relevance, which are essential for the
food industry's sustainability. Distribution supply
chains are more visible and integrated thanks to I4.0.
Authors [52] noted that digital technology offers real-
time food tracking and administration from farm to
table. Ensuring the sustainability of food items
throughout their lifecycle requires this level of
transparency. Furthermore, intelligent warehousing
and logistics development have been made possible
by these technology breakthroughs, which have
improved distribution efficiency and decreased
carbon footprints, all supporting environmental
sustainability.
4.6.2 Technology Adoption Trends
The theme analysis reveals essential trends in the
food industry's adoption and application of Industry
4.0 technologies. The increasing integration of
blockchain with loT technologies is a prominent
trend, as [117] highlighted. Because of these
technologies' capacity to improve supply chain
traceability and transparency, which significantly
advances sustainable practices, they are being
increasingly implemented.
Figure 18. Familiarity with I4.0 Terms [122].
Another trend is employing big data analytics and Al
to handle complex supply chain operations and
predict market trends, according to [46]. These
technologies enable food producers to reduce waste
and maximize resource utilization while promptly
responding to consumer needs and market shifts.
4.6.3 Sustainability Implications
The food industry's adoption of I4.0 carries
significant consequences for sustainability, including
economic, social, and environmental aspects.
Economically, as the theme analysis clarifies, I4.0
technologies like loT and Big Data increase
productivity and efficiency, dramatically lowering
operating costs and waste [117]. Implementing these
technologies reduces resource utilization and carbon
emissions environmentally. Integrating Industry 4.0
technologies, especially in sustainability, shows
PepsiCo's environmental responsibility. The
company's pep+ (PepsiCo Positive) strategy
transforms operations and innovation [123]. PepsiCo
takes sustainability seriously by employing Al to
detect factory water leaks and developing bio-based
product displays. These activities, data-driven
decision-making, and tech startup alliances
demonstrate PepsiCo's commitment to Industry 4.0
for food industry sustainability. Blockchain and CPS

increase food waste traceability and quality control,
essential to environmental sustainability [46]. I4.0
technology can improve food quality and safety,
boosting customer confidence and public health.
However, it also brings up skill gaps and labour
displacement issues, which makes workforce
development and training essential [52].
4.7 Critical Analysis: SWOT Evaluation of
Literature Findings
Strengths, Weaknesses, Opportunities, and Threats
are the four main components that make up the
acronym SWOT analysis. This strategic tool is used
to identify opportunities and threats from the outside
as well as internal strengths and weaknesses.

SWOT analysis is a frequently used method for
strategic planning. The method first developed by
Albert Humphrey, a well-known researcher and the
head of Stanford University's Team Action Model
(TAM) research team in the 1960s and 1970s. The
SWOT analysis provides a strategic perspective on
the industry's ability and readiness to incorporate
Industry 4.0 technologies, offering a summary. The
analysis provides a detailed understanding of the
organization's abilities and limitations by examining
internal factors such as industry-specific strengths
and weaknesses. It simultaneously analyses external
factors, including opportunities and threats, to help
identify potential areas for growth and challenges
within the industry's environment [124-127]. The
SWOT analysis, as presented in Table 4, identifies
crucial factors related to technological potential,
obstacles to adoption, enhancements in processes,
and measures to mitigate risks. It consolidates
findings on the promises of sustainability, economic
considerations, societal impacts, and challenges in
implementation.
4.8 Critical Reflection
When the findings are examined critically, it
becomes clear that Industry 4.0 technologies have the
potential to revolutionize the food sector, but there
are obstacles to their adoption. The themes found
indicate a dynamic interaction between sustainable
behaviours and technology development. Although
technologies like blockchain and the Internet of
Things fuel innovations in transparency and
efficiency, obstacles, including high implementation
costs and opposition to change, highlight the need for
well-rounded and calculated methods [114,115].
Furthermore, concerns concerning the accessibility
and inclusivity of these technologies are brought up
by the emphasis on process, product, and business
model improvements, especially about smaller
companies in the food industry. The review also
identifies a significant research vacuum regarding
these technologies' long-term sustainability effects
and how they contribute to sustainability that is more
general objectives, such as the SDGs.
Therefore, even while I4.0 offers a route to a
more sustainable food, a thorough grasp of its effects
on the economy, society, and environment is required
to realize its promise fully. Therefore, the critical role
that I4.0 technologies play in promoting sustainable
innovation in the food sector been clarified by this
research. Together, the theme analysis, critical
debate, literature review highlights how these
technologies have the power to improve
environmental stewardship, industrial efficiency, and
traceability significantly. Adopting I4.0 represents a
critical advancement in the development of the food
industry, not only in line with operational and
commercial aims but also in terms of more significant
environmental and social sustainability objectives.

4.9 Conceptual Framework
Implementing I4.0 in food manufacturing industry
should consider a conceptual model that highlights
necessary obstacles and crucial success factors as
shown in figure 19.
Figure 19 Conceptual Framework for 14.0 and
Sustainability
The model is based on a thorough review of academic
literature and a thematic analysis of secondary data.
To address sustainability goals like transparent
traceability, optimised waste reduction, and
monitored energy efficiency, food producers can
make use of foundational 14.0 technologies, such as
advanced robotics and Internet of Things sensors.
The model also reveals real adoption barriers that
could be carefully addressed during implementation
of 14.0 technologies. Operational development is
slowed down by additional expenses, supply chain
integration's operational complexity, and internal
skill gaps in data and digitization.
5. Conclusion Limitation and Future
Directions
The research showed huge potential of emerging
technologies to advance food system sustainability,
particularly Additive manufacturing, robotics,
Internet of Things (loT), and predictive analytics.
These have potential to significantly increase food
manufacturing transparency, product traceability,
resource efficiency, and waste reduction while
tackling urgent global issues like food scarcity and
climate change. Research measured currently
underutilised potential of certain technologies, such
as digital twin (block-chain, loT), with applications
for reliable monitoring, consumer trust-building, and
verification that are currently ignored in food
industry. Furthermore, analysis highlighted potential
benefits for process optimisation, cost reduction, new
revenue streams, and overall environmental gains
that can arise from companies strategically investing
in integration of analytics, automation, and smart
connected systems throughout value chains. This
validates the extensive financial and ecological
advantages for digitally revolutionising traditional
food production networks, with technologies
advanced enough to be widely accepted. Study also
identified significant barriers that presently stand in
way with implementation of I4.0 systems for
sustainability. It is important to address issues with
process standardisation, high upfront costs, cultural
resistance, and skill gaps in the workforce of the food
industry. Notably, food companies are forced to
adopt these cutting-edge technologies regardless of
their flexible operations by accelerating policy
measures, investor pressure, and shifting consumer
demands for foods sourced ethically and sustainably.
Objective 1: Explore applications and potential
advantages of main Industry 4.0 technologies being
used in food industry today.
Achieved by a thorough analysis based on most
significant findings regarding enormous potentials of
blockchain, advanced robotics, Internet of Things
sensors, and predictive analytics for facilitating
transparency, traceability, resource optimisation, and
waste reductions in the food production and supply
chains. These capabilities directly address the critical
sustainability issues that world's food systems are
currently facing, such as reducing greenhouse gas
emissions, use of chemicals, water waste, and food
loss while advancing use of renewable energy
sources, circular resource flows, and ethical sourcing.
Objective 2: Examine how Industry 4.0
technologies, with a focus on resource efficiency,
waste reduction, and environmental impact that
promotes sustainability in food production.
Identifying how cutting-edge I4.0 technologies can
promote greater sustainability in second research
objective. The application of I4.0 technology to
create blockchain traceability platforms that provides
unprecedented transparency directly relates to
fundamental concept of maximising potential of
technological integration opportunities to confirm
ethical source of products, their sustainability
credentials, and to enable circular resource flows in
line with research themes. On the other hand, goal of
qualifying mechanisms for reducing waste, resource
depletion, and environmental footprints during food

production and distribution is fulfilled by potential of
loT systems, intelligent robotics, and predictive
analytics to optimise transportation emissions,
refrigeration-heating energy uses, and model plan
distributions.
Objective 3 - Consider economic, environmental,
and social factors as you evaluate the opportunities
and challenges of implementing I4.0 technologies for
sustainable innovation in the food industry.
Through a balanced analysis of financial incentives
like new revenue streams, competitive
differentiation, and cost savings against obstacles
around technical integration, standardisation, skill
gaps, and security needs, goal of evaluating linked
opportunities and challenges was effectively
fulfilled. Furthermore, implications discussed ranged
from promoting policy partnerships that are essential
for infrastructure readiness to building customer trust
by addressing counterfeit concerns.
Research represents a fundamental contribution to
advancing digitalization for global transformation of
food sector by thoroughly assessing Industry 4.0's
sustainability benefits along with significant practical
applications within current food manufacturing
environments. Provided that these technologies are
implemented with purpose, they can mitigate a wide
range of sustainability challenges, from soil depletion
and ethical sourcing to food waste as well as
greenhouse gas emissions.
A major limitation of this study is its limited
temporal scope, as research was restricted to a
specific timeframe. This constraint hampers thorough
investigation of dynamic nature of Industry 4.0
applications in food manufacturing industry over a
long period of time. Due to time limitations, only
secondary data review was used, and primary data
collection methods were not included. This constraint
impedes achievement of deeper and more
transformative empirical insights into research
phenomenon. The availability of comprehensive and
standardized metrics related to adoption of Industry
4.0 in food manufacturing industry is limited. Data
accuracy and comparability may be affected by
differences in reporting and measurement practices
among various sources.
A thorough assessment of potential in Industry 4.0
technologies promotes sustainability in food systems.
However, continuous advancements in areas such as
artificial intelligence, blockchain, and robotics offer
plenty of opportunities for further investigation as
their adoption progresses. According to the analysis,
there is general agreement that more research is
necessary, especially in areas like marketing
innovations, organizational and open innovations,
and the impact of these technologies on long-term
sustainability [52, 114]. Studies underscore the need
to investigate these promising domains, highlighting
the continuous progression and possibilities of
Industry 4.0 within food sector [114]. Due to
depletion of numerous traditional biological
resources for food production worldwide, there is a
growing demand from consumers for healthier and
more sustainable products. This has led to an
increased necessity for alternative food resources
[43]. (2022). Emerging products derived from
cultured meat, meat alternatives, plant-based
proteins, insect-based proteins, and similar sources
have demonstrated considerable promise. The
utilization of raw materials and emerging
technologies can serve as valuable assets in the
creation of highly accurate personalized nutrition
recommendations [43]. Furthermore, they can also
promote favourable consumer behaviour and
promote a wider range of consumption patterns,
ultimately resulting in improved health and enhanced
food sustainability.
