Introduction
The necessity for sustainable manufacturing has emerged as a crucial concern in the 21st century due to the global community's efforts to address significant environmental issues, limited availability of resources, and the repercussions of an unwavering focus on industrial expansion [1].With the ongoing growth of the global population and the corresponding rise in demand for consumer products, energy, and infrastructure, it has become evident that conventional manufacturing practises are no longer viable in the long term.Human activities have exerted pressure on the Earth's ecosystems, leading to their degradation, the depletion of limited resources, and the acceleration of climate change.In light of this urgent circumstance, sustainable manufacturing has arisen as a pivotal shift in thinking, embodying a trajectory aimed at reducing the ecological consequences of industrial operations while simultaneously promoting economic advancement and public welfare.The traditional industrial paradigm, which follows a linear "take-makedispose" framework, has historically operated under the assumption of inexhaustible resources and the transfer of environmental burdens to other entities.In the present model, there is an excessive extraction of raw materials, which is conducted at a rate that is not environmentally sustainable.These raw materials undergo processing and conversion into various goods.However, it is important to note that these products ultimately become garbage, which is disposed of either in landfills or through incineration methods.The adoption of a linear strategy has led to substantial environmental consequences, including the degradation of habitats, pollution, and the accumulation of greenhouse gases in the atmosphere.The repercussions of this nonviable model are progressively manifesting themselves through the occurrence of climate change, the depletion of biodiversity, and the shortage of resources [2].The old manufacturing model is being challenged by sustainable manufacturing, which promotes a circular and regenerative approach.Fundamentally, sustainable manufacturing task to minimise the generation of waste, decrease the utilisation of resources, and diminish the environmental impact associated with industrial procedures.The necessity of sustainable manufacturing is rooted in its capacity to alleviate the detrimental environmental consequences of industrialization, while concurrently addressing the social and economic aspects of sustainability.A key element of sustainable manufacturing is the principle of "design for sustainability."Under this framework, items are designed and engineered with consideration for their complete lifecycle, from the extraction of raw materials to the eventual disposal or recycling at the end of their useful life.The objective of design for sustainability is to reduce resource utilisation, energy consumption, and waste generation through the prioritisation of environmentally friendly materials, efficient production methods, and the incorporation of recyclable or biodegradable components [3].The promotion of the incorporation of renewable resources, such as solar and wind power, into manufacturing operations is advocated, resulting in a decrease in dependence on fossil fuels and a reduction in the production of greenhouse gases.In addition, sustainable manufacturing advocates for the adoption of cutting-edge technology and novel materials.The utilisation of additive manufacturing, more generally referred to as 3D printing, serves as a prime illustration of how technology may be effectively employed to achieve sustainable objectives.The utilisation of 3D printing technology enables the achievement of precise and timely manufacturing processes, resulting in a substantial reduction in both material waste and transportation expenses.Moreover, it facilitates the fabrication of complex and lightweight architectures that were previously unachievable using conventional techniques, hence boosting energy efficiency and optimising material use [4]- [8].The concept of sustainable manufacturing encompasses the field of materials science as well.Scientists are currently engaged in the advancement of a diverse array of sustainable materials, including bioplastics, recycled metals, and bio-composites.These materials are not only ecologically sound but also possess the necessary mechanical characteristics to fulfil a variety of practical uses.These materials has the capacity to bring about a significant transformation in several industries through the reduction of dependence on primary resources and the mitigation of environmental consequences associated with production processes [9].In conjunction with the technical dimensions of sustainable manufacturing, the significance of social responsibility and ethical practises cannot be overstated.Manufacturers and designers are obligated to take into account the welfare of workers, local communities, and the world population as a whole.Ethical labour practises, equitable remuneration, and secure working environments are vital elements of sustainable production.In addition, it is imperative for manufacturers to actively involve themselves in local communities, actively soliciting their feedback and addressing any problems that may arise [10].This approach is crucial in order to ensure that the advantages of industrialisation are spread in a fair and equitable manner.
In addition to its use on the factory floor, sustainable manufacturing encompasses the fundamental principles of a circular economy.The focal point of this economic framework lies in the promotion of the reuse, refurbishment, and recycling of items and materials, hence redirecting them away from landfills and incineration facilities [11].Through the implementation of extended producer responsibility programmes, manufacturers assume accountability for the complete life cycle of their products, thereby fostering the collecting and recycling of utilised things.The circular economy not only facilitates resource conservation but also engenders novel economic prospects, such as the practise of remanufacturing and the establishment of secondary markets for recycled materials.The concept of sustainable manufacturing also acknowledges the significance of engaging stakeholders in collaborative efforts.In order to advance sustainable practises, it is imperative for manufacturers, designers, consumers, and legislators to collaborate harmoniously [12].The alignment of interests towards sustainability is significantly influenced by transparent supply chains, ethical consumer choices, and severe environmental regulations.In addition, the implementation of education and awareness campaigns plays a crucial role in facilitating the transformation of societal norms towards consumption patterns that are more sustainable.These efforts effectively promote the adoption of informed decision-making and the endorsement of sustainable products among individuals [13]- [15].The obligation to engage in sustainable manufacturing include the crucial aspect of restoring and preserving ecosystems.The objective of sustainable manufacturing is to mitigate the adverse environmental impacts resulting from industrial activity through the implementation of ecosystem restoration projects [16].For example, firms have the opportunity to allocate resources towards reforestation programmes as a means to counterbalance carbon emissions, or alternatively, contribute to initiatives aimed at safeguarding crucial habitats.Sustainable manufacturing plays a significant role in the restoration of ecosystems, thereby contributing to the regeneration of natural resources and facilitating the reestablishment of the intricate equilibrium of our planet.Energy efficiency is a fundamental component of sustainable production.Given the ongoing increase in global energy consumption, it is crucial to prioritise the transition towards sustainable energy sources.Sustainable manufacturing facilities are progressively dependent on renewable energy sources, including solar, wind, and hydropower [17].The implementation of energy-efficient technologies, in conjunction with intelligent energy management systems, contributes to the reduction of energy consumption, the decrease in operational expenses, and the mitigation of the carbon footprint associated with industrial processes.Additionally, the implementation of legal and policy frameworks is crucial in promoting and encouraging the use of sustainable manufacturing practises [18].It is imperative for governments and international organisations to establish unambiguous benchmarks and offer financial incentives in order to foster the adoption of sustainable practises among enterprises.These measures encompass carbon pricing mechanisms, tax incentives aimed at promoting eco-friendly investments, and rules that require eco-labeling and product lifecycle analyses [19].
Public awareness and education play crucial roles in the imperative for sustainable production.As individuals gain greater awareness of the ecological and societal consequences associated with their consumption patterns, they possess the capacity to stimulate the market for sustainable goods and exert pressure on manufacturers to uphold responsible practises.Education campaigns, sustainability certifications, and comprehensive reporting on environmental and social performance serve as crucial tools for empowering customers to make well-informed decisions that align with the principles of sustainable production [20].In the current era, the global community is confronted with a pivotal moment, characterised by a multitude of environmental obstacles that necessitate a profound reassessment of our methods for generating commodities and facilitating transactions.In light of the prevailing issues of climate change, resource depletion, and ecological degradation, a novel concept referred to as "regenerative manufacturing" has emerged and gained traction.Regenerative manufacturing has emerged as a viable solution to address the constraints and deficiencies inherent in conventional manufacturing methods.This innovative approach not only task to mitigate environmental damage but also strives to rejuvenate and invigorate ecosystems, communities, and economies.This essay examines the birth of regenerative manufacturing, delving into its fundamental principles and assessing its potential to influence a future characterised by sustainability and regeneration [21].The prevailing style of production globally has historically been traditional manufacturing, which is characterised by linear and extractive processes.Within this conventional framework, the procurement of raw materials takes place, followed by their conversion into finished products, and ultimately culminating in their disposal as waste.The utilisation of a linear method has resulted in the exhaustion of limited resources, the degradation of habitats, and the accumulation of pollutants and greenhouse gases.The implications of this concept have been progressively evident, as indicated by the escalating global temperatures, extinction of species, and damage of the ecosystem.Regenerative manufacturing has emerged as a viable solution to address the environmental crises that have been also compounded by conventional manufacturing practises [22]- [26].
The concept of "design for regeneration" is a fundamental premise in the field of regenerative manufacturing.This theory underscores the significance of incorporating ecological concepts into the design and production processes of various products.The concept of design for regeneration extends beyond mere environmental harm reduction, as it actively task to develop goods and systems that exert a beneficial influence on the ecosystems they engage with [27].This entails emulating nature's effective and sustainable mechanisms, such as circularity and the optimisation of resources.Biomimicry, an integral element of design for regeneration, entails deriving inspiration from nature's mechanisms for addressing intricate challenges [28].For instance, an examination of the hierarchical arrangement of branches in a tree can serve as a source of inspiration for the optimisation of distribution networks, whereas a comprehensive comprehension of the inherent ability of some species to regenerate and repair themselves can contribute to the advancement of durable materials.Biomimicry promotes the practise of designers and engineers seeking inspiration from the natural world in order to develop new and environmentally sustainable solutions.Generative design is an additional facet of design for regeneration that utilises computer techniques to enhance designs by optimising them according to particular criteria.Generative design software has the capability to generate designs that optimise material utilisation, minimise waste generation, and improve energy efficiency by including environmental and sustainability objectives.This not only facilitates the development of sustainable products but also enhances creativity by enabling the exploration of design alternatives that may not be readily apparent to human designers [29].The third component of design for regeneration, known as modular and adaptive design, places emphasis on the development of goods that possess the ability to be disassembled, repaired, and improved with ease.This methodology effectively mitigates the necessity for frequent substitution and disposal, hence prolonging the durability of goods and mitigating the ecological repercussions associated with production [30]- [31].Technological breakthroughs have a significant impact on the development of regenerative manufacturing.Advanced manufacturing technologies, such as additive manufacturing, colloquially referred to as 3D printing, are fundamentally transforming the production landscape.The utilisation of 3D printing technology enables the achievement of accurate and customizable manufacturing processes, while minimising the generation of excess material waste.Additionally, it facilitates the development of intricate and lightweight constructions that were previously difficult to attain using conventional techniques [32].This technique is in accordance with the concepts of regenerative manufacturing since it effectively minimises material waste and energy usage.
The utilisation of digital twins, which are virtual replicas of tangible entities or systems, is progressively gaining prominence within the area of sustainable manufacturing.These technologies provide the continuous monitoring, analysis, and optimisation of production processes in real-time.Digital twins play a crucial role in the identification of potential for resource efficiency and waste reduction by simulating manufacturing scenarios and assessing environmental implications.This technology enables producers to make well-informed decisions that are in line with the principles of regeneration.The integration of the Internet of Things (IoT) inside the manufacturing sector is a significant factor in the advancement of regenerative manufacturing.Internet of Things (IoT) devices possess the capability to gather and communicate data pertaining to energy consumption, machinery functionality, and environmental circumstances.The aforementioned data has the potential to provide valuable insights for making informed decisions pertaining to energyefficient production, predictive maintenance, and environmental sustainability [33]- [36].The implementation of Internet of Things (IoT) technology allows manufacturers to enhance their operational efficiency while simultaneously reducing their impact on the environment.Regenerative manufacturing focuses significant importance on ethical and social responsibility as well.The recognition of the connection among various stakeholders, including manufacturers, designers, customers, and local communities, is evident.The incorporation of ethical manufacturing practises, fair remuneration, secure working environments, and the upholding of human rights are fundamental components of regenerative manufacturing.The primary focus is on promoting the welfare and livelihoods of employees and local communities, so cultivating economic resilience and ensuring social equality.The establishment of transparent supply chains is a fundamental element in the context of ethical production.Consumers can make educated decisions that are consistent with their beliefs by gaining access to information regarding the origins and production methods of items.The transparency provided by this approach also serves to ensure firms are held responsible for their environmental and social practises.The selection of ethical consumer options has the potential to stimulate the demand for sustainable and regenerative products, thereby incentivizing enterprises to embrace responsible practises [37].Community participation plays a vital role in the area of regenerative manufacturing.It is imperative for manufacturers to proactively solicit input from local communities, effectively address their issues, and make constructive contributions to their overall welfare.By actively engaging communities in the decision-making processes, manufacturers may effectively ensure that their activities have a positive impact on the local regions in which they are situated, rather than causing any detrimental effects [38].These programmes have a significant role in enhancing economic resilience and promoting the well-being of the community.

Principles of Regenerative Manufacturing
The concept of design for regeneration is a fundamental aspect of regenerative manufacturing, which fundamentally transforms our understanding, production, and engagement with various goods and systems.The concept of design for regeneration is fundamentally based on the notion that industrial processes should not solely focus on reducing environmental harm, but should actively seek to make positive contributions to ecological health and resilience.This methodology utilises the ingenuity of natural systems, employing concepts derived from the natural environment, including biomimicry, generative design, and modular and adaptive design.This investigation focuses on the examination of three fundamental elements of design for regeneration, elucidating their transformative impact on manufacturing methodologies and their contribution to the advancement of sustainability objectives.Biomimicry and nature-inspired design are two closely related concepts that have gained significant attention in the field of engineering and design.Biomimicry refers to the practise of emulating and drawing inspiration.Biomimicry, often known as nature-inspired design, is a fundamental aspect of regenerative manufacturing that draws inspiration from the diverse and intricate patterns found in the natural world [39].This methodology entails examining and replicating the astute tactics, structures, and mechanisms observed in ecosystems, species, and animals in order to develop sustainable and regenerative solutions.The underlying principle of biomimicry posits that nature, over billions of years of evolution, has already effectively addressed numerous intricate design and engineering problems encountered by humans, as shown in fig. 1.

Fig.1 Generative Design application in manufacturing
Within the field of manufacturing, biomimicry presents a vast array of inventive concepts.Engineers have successfully derived stronger and lighter materials for a wide range of uses, such as aviation components and building materials, through the analysis of honeycomb structures.The vascular structure found in leaves has served as a source of inspiration for the development of transport networks that are characterised by enhanced efficiency and resilience.The unique characteristics of geckos' feet have prompted the advancement of adhesive materials that provide non-destructive adhesion and detachment, hence minimising waste in production and maintenance procedures.The concept of biomimicry promotes a significant transformation in cognitive processes, urging designers and engineers to perceive nature not merely as a means to exploit, but rather as a source of guidance and inspiration [40]- [42].Generative design, which utilises sophisticated algorithms and computational technology, is a significant aspect of design for regeneration.Generative design, fundamentally, revolves around leveraging computational capabilities to optimise and enhance designs according to predetermined criteria, including but not limited to sustainability, efficiency, and material utilisation.Through the utilisation of these criteria, designers have the opportunity to delve into a wide range of design alternatives that may not be readily apparent to human designers.This process ultimately leads to the development of solutions that are more efficient in their use of resources and more environmentally sustainable.The process of generative design commences by constructing a digital representation of the desired product or system.This model functions as a platform for conducting experiments, in which designers input their design objectives, limitations, and performance metrics.The generative design programme utilises sophisticated algorithms to produce and iterate designs that satisfy the predetermined criteria [43].The designs exhibit a range of variations in terms of geometry, material utilisation, and other characteristics, hence demonstrating a multitude of potential solutions [44].Modular design encompasses the development of goods or systems comprising distinct modules or components that possess the capability of being readily replaced or improved.This technique differs from conventional monolithic designs, which can pose difficulties or cost impracticalities when it comes to repairs and upgrades.Modular smartphones provide customers the capability to substitute specific components, like as the camera or battery, as opposed to the complete replacement of the entire device.Not only does this practise contribute to the reduction of electronic waste, but it also fosters resource efficiency.Adaptive design extends the principles of modularity by developing products that possess the ability to evolve and adjust in response to shifting requirements and circumstances.In the field of architecture, adaptive building designs have the potential to adjust and adapt to fluctuations in temperature, occupancy levels, and energy availability.This capability allows for the optimisation of both comfort levels and resource utilisation.Adaptive systems have the capability to achieve responsiveness through the integration of sensors, actuators, and intelligent technology.Modular and adaptive design strategies effectively correspond with the regenerative manufacturing philosophy as they contribute to waste reduction, resource conservation, and the cultivation of a repair and reuse-oriented culture.They facilitate the adaptation of products and systems to changing circumstances, hence mitigating the necessity for new replacements and prolonging the lifespan of current assets.The pursuit of regenerative manufacturing involves a strong interconnection between the principles of modular and adaptive design, as well as the concepts of a circular economy and sustainable materials management.These principles acknowledge the significant influence of material choices on the environmental and economic sustainability of manufacturing operations.This study examines three key elements of material innovation and the circular economy in the context of modular and adaptive design: sustainable materials selection, closed-loop material cycles, and recycling and upcycling solutions.Collectively, these components constitute a robust basis for regenerative manufacturing, presenting a trajectory towards waste reduction, improved utilisation of resources, and ecological rejuvenation [45]- [46].

The Role of Technology and Innovation
Technology and innovation are crucial factors in the advancement of regenerative manufacturing, as they have the power to transform conventional production methods and promote sustainability.Advanced manufacturing technologies play a prominent role in driving this change by providing novel approaches to minimise waste, boost the efficient utilisation of resources, and bolster the overall environmental and economic sustainability of manufacturing processes.This study examines three fundamental elements of sophisticated manufacturing technologies in the area of regenerative manufacturing: Additive Manufacturing (also known as 3D Printing), Nanotechnology and Materials Science, and the Internet of Things (IoT) and Data Analytics in the field of manufacturing.Collectively, these technical breakthroughs are facilitating the shift towards manufacturing practises that are more sustainable and regenerative in nature.The technology of additive manufacturing, also referred to as 3D printing, has emerged as a transformative innovation with significant implications for regenerative manufacturing [47].Also, it presents the possibility of decentralised and regionalized manufacturing.This implies that the production of goods can be localised in proximity to the intended consumers, hence mitigating the necessity for extensive transportation and the consequent release of carbon emissions.Moreover, the utilisation of 3D printing technology has the potential to facilitate the production process in a manner that allows for immediate fulfilment of consumer demands, hence minimising the need for excessive inventory and mitigating the associated risks of overproduction.Also, the utilisation of 3D printing technology is playing a significant role in the advancement of sustainable materials.Scientists are currently engaged in ongoing research task to develop bio-based and recycled materials that demonstrate compatibility with 3D printing methodologies.These materials possess the twin benefit of less environmental impact and more design freedom [48].
Nanotechnology is also of critical importance in enhancing energy efficiency and promoting sustainability.Nanomaterials have the potential to augment the operational capabilities of photovoltaic cells, hence amplifying the conversion efficiency of solar energy into electrical power.In a similar vein, the application of nanocoatings has been found to effectively mitigate friction and wear in industrial machinery, hence resulting in notable energy conservation and prolonged operational durability of the equipment.In addition, nanotechnology plays a significant role in enhancing resource efficiency through its ability to exert precise control over material properties.This phenomenon has the potential to facilitate the creation of materials that possess diminished resource demands [49].For instance, it can enable the fabrication of lightweight structural elements that exhibit both strength and durability, hence necessitating a lower quantity of raw materials and energy during the manufacturing process.The field of materials science serves as a valuable complement to nanotechnology, as it establishes a fundamental basis for the development and production of environmentally-friendly materials.Academic researchers are currently engaged in the exploration of alternative materials, with the aim of identifying solutions that include both environmentally sustainable characteristics and the requisite mechanical capabilities for diverse applications.The utilisation of sustainable materials, such as bioplastics sourced from renewable resources or recycled metals, is becoming increasingly prominent in the field of regenerative manufacturing.These materials serve to decrease the dependence on primary resources and alleviate the environmental consequences associated with industrial operations.Also, ongoing investigations in the field of materials science are revealing novel methodologies, such as the development of self-healing materials capable of autonomously repairing damage.This advancement holds the potential to significantly prolong the durability of various products, hence mitigating the necessity for frequent replacements.In brief, the fields of nanotechnology and materials science play a crucial role in the progression of regenerative manufacturing by facilitating the creation of materials that possess improved characteristics and a focus on long-term viability.The integration of these disciplines facilitates the development of environmentally sustainable materials and methodologies that adhere to the ideals of waste minimization, efficient resource utilisation, and responsible environmental The integration of the Internet of Things (IoT) and data analytics is facilitating a paradigm shift in the manufacturing industry, characterised by enhanced precision, efficiency, and sustainability.These technologies provide the continuous monitoring, analysis, and optimisation of industrial processes, thereby offering useful insights to mitigate wastage, boost the utilisation of resources, and improve environmental performance.The Internet of Things (IoT) encompasses the integration of physical items and devices with internet connectivity, enabling them to gather and share data.In the manufacturing domain, Internet of Things (IoT) sensors are integrated into machinery, equipment, and even goods, facilitating the acquisition of real-time data pertaining to diverse facets of the production process [50].As shown in Fig. 2, the Internet of Things (IoT) sensors have the capability to monitor several elements, including but not limited to temperature, humidity, energy usage, and machine performance.The aforementioned data is thereafter communicated to a centralised system, wherein it can be subjected to analysis and utilised for the purpose of making well-informed decisions.Predictive maintenance stands as a prominent advantage of implementing Internet of Things (IoT) technology inside the manufacturing sector.Through the constant monitoring of equipment, Internet of Things (IoT) sensors possess the capability to identify initial indications of deterioration, malfunctions, or inefficiencies.This enables manufacturers to proactively plan maintenance activities, thereby minimising instances of unplanned downtime, prolonging the operational lifespan of equipment, and promoting resource conservation.The Internet of Things (IoT) has a substantial influence on energy efficiency.Sensors possess the capability to actively monitor and track energy use in real-time, hence enabling the identification of potential areas for optimisation.Manufacturers have the potential to decrease energy costs and mitigate their carbon emissions by making modifications to equipment settings or production schedules in response to energy demand.Data analytics, which is enhanced by the utilisation of machine learning and artificial intelligence techniques, serves as a valuable adjunct to the Internet of Things (IoT) by effectively handling and deciphering the extensive volumes of data produced by IoT sensors.Sophisticated algorithms possess the capability to scrutinise past data, discern recurring trends, and generate prognostications regarding forthcoming manufacturing results [51].
