Introduction

Environmental thinking is the aim of being integrated into supply chain management through the emergence of the green supply chain, which is one of the essential topics in the awareness spread regarding environmental issues in the last few decades. Many organizations respond to environmental issues by implementing green principles to companies; by using environmentally friendly raw materials, reducing the usage of petroleum power, recycling papers for packaging, and recycling electronic waste. The concept of green supply chain management has emerged in the last few years. It covers every stage in manufacturing, from the first stage to the last one, of the life cycle, i.e., from the approval of the product design till the moment of recycling. It covers many other functions besides manufacturing, but, it also includes the various activities involved in reverse logistics. Reverse logistics is defined as the process of transporting products from their place of use to their place of production for reuse, rework, repairs, remanufacturing, or recycling. Since reverse logistics is an integral part of green supply chain management, it is important to represent the connection between them and analyze their importance within the organization's performance, in order to have a complete supply chain (pandian & Abdul-kader, 2014).

Problem and Motivation of Research

The purpose, in this research, behind choosing Egypt as the country of study, not only because it is one of the highest consuming countries of electronics in the middle east, but also it has a remarkable increase of awareness regarding dealing with waste correctly among different industries. In other words, this research will first examine the general reverse logistics and its characteristics to gain a deeper understanding of the subject. This will be done to acquire the necessary background information required to research, understand and analyze the different reverse logistics characteristics of the mobile phone industry and to create recommendations for the recovery, repairing, remanufacturing, and recycling of mobile phones in today's environmental context.

In order to first gain a better and more profound understanding of grl, the present research will strive to answer the following questions:

1. What is the rl, and what activities include?

2. What are the grl motivators?

3. What are the challenges of the grl flow in the e-waste?

Research Objective

The following specific objectives guided the study:

1. To identify rl and grl.

2. To reduce the e-waste in Egypt

3. To reduce the damage to the environment through the implementation of grl.

Conceptual Background

Green Supply Chain Management

The green supply chain concept was first developed in 1996 by Michigan state university during the research entitled "environmentally responsible production."

The scholars at Michigan state university had proved to be an effective way of managing it. Later, they found the establishment of green supply chain management in such enterprises as IBM effectively resolved the conflict between environmental protection economic interests, so it is admired by people.

The green supply chain originates from the notion of supply chain management and the theory of sustainable development. It's a new topic. People weren't studying it deep enough. There is no unified, clear, authoritative definition yet. Management of the green supply chain is one system. It covers acquiring, processing, packaging, warehousing, transporting, selling, and end-of- life treatment, recycling. The process is guided by the principle of resource allocation optimization, enhancing benefits, achieving the objective of environmental compatibility. In general, it is a green system that brings together suppliers, manufacturers, distributors, retailers, consumers, the environment, rules, and cultural elements. It's also the logistics combination, information flow, cash flow, knowledge flow.

In general terms, the green supply chain management is a supply chain guided by the theories of sustainable development. Its purpose is to achieve the goal of improving welfare, achieving environmental compatibility, and optimizing materials by improving speed, certainty, and other related channels. Because of this, short-term benefits and long-term benefits cannot be handled well. Therefore, the establishment of green supply chain management is necessary so that the enterprise can have sustainable development.

Green supply chain management is a complex system, involving suppliers, manufacturers, distributors, retailers, customers, and logistics providers from the perspective of the participants.

Green supply chain management started mainly from product design and ended with the recycling of the final product. It covers mainly the following five aspects; they are green procurement, green design, green production, green distribution, green logistics, green consumption, and green recycling. Three of them will be discussed later green design, green procurement, and green production.

1. Integrating natural deduction into SC the executives, including the biological plan of items, buying green materials and parts, reengineering of assembling ventures towards eco-friendly, turn around coordination is the executives of the item after its valuable life.

2. Integrating ecological thought onto firms' SC, including reverse coordination's.

3. Reducing and controlling the destructive effects of SC on earth.

4. Adoption of a natural plan, sourcing green materials and synthetic compounds, and give green training to workers under moral authority.

5. Green flexibly chain incorporates the eco-friendly idea into gracefully anchor the board to improve natural manageability with various green works on including, green buying, green dispersion, and warehousing, green transportation with utilization of biofuels, green assembling forms and the items' finish of-life the board.

6. In the world, as the natural mindfulness is expanding, firms are confronting substantial weight from various partners, including government and clients, to relieve their hurtful impact on the earth. Undoubtedly, corporate division needs to consider incorporating their strategic approaches in administration and assembling industry with manageability and diminishing start to finish gracefully anchor expenses to accomplish the upper hand. Since the most recent few decades, developing effects of an earth-wide temperature boost, environmental change, waste, and air contamination issues have included expanding overall consideration of specialists to think all the more eco- friendly and discover ideal conceivable arrangements towards "green." rath recognized GSCM (flexible green chain the board) has an impact in rousing authoritative supportability. With the natural concerns rising constantly, GSCM merits an industrious network worry in created countries. Further, it has as of late woken up the creating countries to green development.

Green Design

Study shows that in the design stage, around 70-80 percent of the product performance is determined. (toppinen et al., 2013; khalil et al., 2013; wang & luo, 2010) while the design usually costs only 10 percent of the total cost, however. Therefore, in the design stage of products, full consideration should be given to the ecological and environmental impacts. The designs can thus reduce energy consumption and pollute the environment. Green designs include mainly research into standardized, modular, removable, and recoverable design.

1. The standardized design makes parts of the structure relatively fixed, thus reducing processing difficulties and energy consumption. It can also decrease the complexity of technological devices.

2. The modular design is designed to meet the rapid development of green products, making it easy to assemble, disassemble, and maintain the product.

3. The removable design means that all parts of the structure have a reasonable, accessible, and separate coupling structure, which is easy to remove without damaging parts to reduce pollution from the environment.

4. The recyclable design is a design that achieves maximum component reuse.

Green Procurement

The procurement consists of buying raw materials (christopher, 2005). It is a supplier concern and a logistics concern. Many aspects should be considered in order to keep the whole routine clean and secure. To ensure that the entire supply chain is carried out successfully, consideration should be given to both the supplier and the logistics.

Green Production

Consideration should be given to the input and output of the manufacturing process, resource consumption, and environmental impact during the green production process. That includes the flow of materials, the consumption of resources, and waste production. The following aspects should be considered as regards green production.

1) Green skills. The environmental factors should be considered first in the selection process for the plan.

2) Productive resources. The reduction of waste and scrap material should be considered, with a higher level of processing technology.

3) Enhance manufacturing humanity by adjusting working hours and reducing labor intensity and other measures to increase employee enthusiasm and productivity creativity.

4) Attach importance to protecting the environment.

Obstacles to Green Supply Chain Management Practices

Researchers have identified many roadblocks that organizations face when implementing GSCM. As is the case with any novel company concept, firms are likely to face obstacles as they strive to develop this business model. The Ryder center for supply chain management (2008) identified three obstacles businesses face when greening their supply networks. These include a scarcity of appropriate technology to aid in the endeavor to become green, a desire for business processes to gather the necessary data in the supply chain to enable the use of the available technology, and a trade-off between green demands and lean approaches (Jlopleh – warner, 2012) It has been noted that technology enables the development of energy-efficient solutions that have a far more significant favorable effect on the environment. Thus, information technology can contribute to a more sustainable supply chain by optimizing the resources required to run the organization. The researchers cautioned that green supply chain technology would be challenging to implement in isolation from the supply chain system's business activities. As a result, the green supply chain and the supply chain are mutually reinforcing. Mollenkopf & colleagues (2010) claimed that lean and green initiatives are frequently viewed as mutually exclusive, owing to their shared emphasis on waste reduction. Lean manufacturing focuses on lowering inventory as it moves through the supply chain, minimizing its negative environmental impact. However, lean solutions that rely on just-in- time (jit) delivery of small batch sizes to promote sufficiency may necessitate more significant transportation, packaging, and handling, which contradicts the green approach.

Most businesses that employ green supply chain techniques incorporate environmental considerations into their SC systems rarely (cash & Wilkerson, 2003). They contended that their approach is frequently motivated by the desire to green an existing process or component of the supply chain. While this may benefit the environment, environmental considerations are usually overlooked when individuals responsible for monitoring a business's overall supply chain performance make supply chain modifications. Additionally, they stated that it is only after supply chain improvements have been implemented and their impact on the environment has been determined that the concept of greening the supply chain has a chance to arise (cash & Wilkerson, 2003). According to research on the challenges to GSCM application in the Indian automobile sector, the cost is a significant constraint in GSCM compared to traditional SC. Green techniques such as green design, green production, and green labeling of packaging, among others, need an excessive initial expenditure. The researchers agreed that environmental engagement entails two distinct expenses: direct costs and transaction costs. These costs, alkhidir & zailani (2009) assert, are likely to provide significant obstacles to GSCM deployment. Any strategic program's success requires the support and dedication of senior management (Hamel & Prahalad, 1989; zhu & Sarkis, 2007). Support from senior management is especially beneficial for environmental activities such as GSCM. It possesses a considerable influence on, and support for, the actual formation and implementation of green initiatives within the organization (zhu & Sarkis, 2007). GSCM is typically continuously supported by top management through strategic strategies and action plans for successful deployments. As a result, without top management backing, the execution of GSCM efforts will stall.

Green Supply Chain Management Strategies

Researchers and professionals of GSCM have identified various strategies that, if well applied, can lead to the realization of the benefits of GSCM. According to Simpson & Simpson (2008), one such strategy is risk-based strategies that focus on risk minimization Organizations apply this strategy in response to shareholders' requirements, and it is ideal for an organization that retains minimal internal environmental management resources. Since the technique depends on insignificant between hierarchical commitment, it may include considering essential statements in buying contracts for providers to meet all appropriate administrative prerequisites (Simpson & Simpson, 2008). Lord, et al., (2005) commented that this system falls under the built-up international organization for standardization (ISO) 14001. They further noticed that most associations, including Ford Motor Company, utilize the procedure with their providers through to their graceful chains (king et al., 2005) to offer built- up ecological execution benefits (Melnyk, 2003), outsider administration execution a framework all around acknowledged by associations.

The eco-efficiency strategy or lean-and-green approach to GSCM has developed as one of the complex strategies that organizations adopt to address the impact of their activities on the environment (Simpson & Simpson, 2008). This strategy draws environmental performance benefits for the supply chain beyond mere regulatory compliance through suppliers' requirements to meet operations-based efficiency objectives. Much environmental performance comes from specific manufacturing practices that provide secondary environmental performance benefits (Melnyk, 2003). The efficiency-based has both economic and environmental performance benefits to the supply chain and requires a higher level of engagement between customers and suppliers (Simpson & Simpson, 2008). This strategy ties environmental performance to operational processes in the supply chain. It allows the Expansion of execution prerequisites into the flexible chain amplifies financial execution and gives optional ecological execution benefits through waste and asset use decreases. The technique requires a more elevated contribution level between gracefully chain accomplices emerging from the increasingly complex utilization between firm execution prerequisites. Be that as it may, utilizing this procedure to encourage more prominent productivity in the flexible chain doesn't require the improvement of co-particular assets explicit to ecological execution (Simpson & Simpson, 2008).

Innovative-based GSCM strategies have been identified to expedite greening the supply chain in most organizations (Simpson & Simpson, 2008). This procedure is not quite the same as the effectiveness-based system due to its utilization of a graceful chain natural execution technique that is all the more explicitly ecological. Bowen & others (2001) saw that associations are progressively mindful of the potential for limited buying strategies to insource parts or administrations from providers that might be lawfully rebellious with ecological guidelines or who themselves secure products in a naturally flippant manner. When a flexible fasten starts to think about specific procedures, advances, or complex execution guidelines for providers, such as compound evasion, the degree of information trade and social speculation starts to change. Moving from an effectiveness-based GSCM procedure to a more considerable degree of advancement or joining of natural execution in the graceful chain and item configuration requires particular ecological assets (Lenox & king, 2004).

According to Simpson & Simpson (2008), closed-loop strategies are a recent type of GSCM strategy representing the complex and collaborative form of GSCM. In its basic form, the closed- loop strategy is often referred to as 'reverse logistics,' which involves the capture and recovery of materials for either remanufacture (high-value) or recycling (low value) (kocabasoglou et al., 2007). These materials can arise during production, as returned goods, post-use, and end-of-life. The strategy integrates environmental performance to the whole supply chain. Prominent examples of companies that have used closed-loop strategy include Kodak's return and remanufacture of its disposable cameras, Hewlett Packard's retrieval of used printer cartridges, and BMW's end-of-life vehicle requirements for suppliers(guide et al., 2002).

However, the motivation for a closed-loop strategy remains low for fundamental reasons of poor and distributed control over the reverse supply chain, lack of available infrastructure, and the inability of supply chains to believe that such activity is economically viable (Simpson & Simpson, 2008).

Richey & colleagues (2005) observed that designing and successfully using a closed- loop strategy presents one of the most complex endeavors for a single organization to do within its supply chain. In its basic form, 'closed-loop' may involve product take-back and reverse logistics implemented only in the retail portion of the supply chain. In more complex closed- loop systems, used or obsolete products and waste are taken back by the producer and remanufactured or recycled (Richey et al., 2005).

Strategies for a Green Supply Chain Management

Researchers and practitioners in GSCM have developed a variety of tactics that, when properly implemented, can result in the realization of GSCM's benefits. According to Simpson & Simpson (2008), one such method is risk-based strategies that prioritize risk mitigation. Businesses pursue this strategy in response to shareholder demands, and it is optimal for businesses with limited internal environmental management resources. The technique's reliance on small commitments between hierarchical levels may include considering strong statements in purchasing contracts with providers to ensure compliance with applicable administrative requirements (Simpson & Simpson, 2008). According to Lord, et al., (2005), this system conforms to the established international organization for standardization (ISO) 14001. Additionally, they observed that most organizations, including Ford Motor Company, utilize the procedure with their suppliers through their graceful chains (king et al., 2005) to offer built-up ecological execution benefits (Melnyk, 2003), outsider administration execution, and a general recognized framework. The eco- efficiency strategy, often known as the lean-and-green approach to GSCM, has evolved into one of the more complicated ways that firms use to address the environmental effect of their activities (Simpson & Simpson, 2008). Beyond legal compliance, this technique helps the supply chain's environmental performance by requiring suppliers to satisfy operational efficiency goals. Much environmental performance is derived through industrial processes that have been identified as providing secondary environmental performance benefits (Melnyk, 2003). The efficiency-based approach improves the supply chain economically and environmentally, and it necessitates a higher level of collaboration between customers and suppliers (Simpson & Simpson, 2008). This technique connects environmental performance to supply chain operating procedures. It enables the expansion of execution prerequisites into a flexible chain, enhancing financial execution and providing optional environmental execution benefits through waste and asset utilization reductions. The technique necessitates a higher level of contribution from gracefully chain accomplices due to the increasingly sophisticated utilization requirements for firm execution. However, employing this technique to promote greater productivity in the flexible chain does not necessitate enhancing co- specific assets related to ecological execution (Simpson & Simpson, 2008). Numerous firms have identified innovative GSCM solutions to accelerate greening their supply chains (Simpson & Simpson, 2008). This approach is distinct from the effectiveness-based system in that it makes use of a more ecological graceful chain natural execution technique. Bowen & colleagues (2001) observed that associations are increasingly conscious of the potential for restricted purchasing strategies to insource components or administrations from providers who may be legally in violation of environmental regulations or who secure products in a naturally flippant manner. When a flexible fastener considers special procedures, advancements, or complicated execution rules for suppliers, such as compound evasion, the degree of information exchange and social speculation changes. Transitioning from a performance-based GSCM procedure to a higher level of advancement or integration of natural execution in the graceful chain and product design necessitates specific ecological assets (Lenox & king, 2004). According to Simpson & Simpson (2008), closed-loop strategies are a relatively new type of GSCM strategy that exemplifies the complex and collaborative nature of GSCM. In its simplest form, the closed-loop strategy entails the capture and recovery of materials for remanufacturing (high-value) or recycling (low-value) (kocabasoglou et al., 2007). These materials may be generated during manufacture, as returned goods, post-use, or at the end of their useful lives. The approach encompasses the entire supply chain in terms of environmental performance. Several notable instances of corporations that have implemented a closed-loop strategy include Kodak's return and remanufacture of disposable cameras, HP's recovery of old printer cartridges, and BMW's requirements for suppliers of end-of- life vehicles (guide et al., 2002). However, motivation for a closed-loop strategy remains low for fundamental reasons such as insufficient and dispersed control over the reverse supply chain, a lack of relevant infrastructure, and supplier networks' unwillingness to think such activity is economically viable (Simpson & Simpson, 2008). According to Richey & colleagues (2005), developing and successfully implementing a closed-loop strategy is one of the most difficult tasks a single firm can do inside its supply chain. In its simplest form, 'closed-loop' may refer to product return and reverse logistics applied exclusively in the retail segment of the supply chain. In more elaborate closed-loop systems, the manufacturer takes back used or obsolete products and garbage and remanufactures or recycles them (Richey et al., 2005).

Results

This research investigated one of the supply chain management disciplines: green reverse logistics and e-waste industry. As shown in this research, green reverse logistics is an important business area and, due to many factors such as environmental concerns, legislation, and customer demands, firms have started to invest time and efforts in order to build efficient reverse flows to gain competitive advantages and respect new environmental laws.

Reverse logistics is a complex field and presents many challenges that have to be overcome when businesses implement reverse flows. These challenges are still complex as reverse logistics remains a new business area, and expertise, in this domain, is still being built. The evaluation and selection of the 3pl for the mobile industry segment is a top management level strategic decision. The quantity of e-waste is tremendously increasing, and it has become a menace to society and environmental burden. The legislations act like Restrictions on Hazardous Substances (ROHS) directive, and Waste Electrical and Electronic Equipment Directive (weee) are gaining importance in the current business environment. The electronics appliances manufacturing companies are more interested in focusing upon their core competencies, and services of 3pl are the right choice for them to separate reverse logistics operations. Therefore, hiring the services of 3pl is an important issue, and the present work is very significant in this regard. Nowadays, efficient reverse logistics operation is regarded as a focused problem. The development of a sound reverse logistics system is beneficial to environmental protection, and the companies may improve their financial health by handling the return professionally. Mostly the manufacturing industries do not have enough competence to manage their product reverse flow in the supply chain; thus, they have to only option to outsource their reverse logistics operations to the 3pl service provider for the conduct of reverse logistics (rl) activities. To make the ahp-topsis model more effective, top management must establish key criteria for the evaluation and selection of third-party logistics service providers. The attributes may increase or decrease as per the industry's needs; in a real-life business environment, it is very difficult to find suitable criteria for the evaluation and selection of outsourcing partners. In the present work, a decision model has been developed for the mobile phone manufacturing company only. However, the same decision model may apply to a different market segment with minor modifications. The hybrid ahp-topsis method presented in this research properly guides policymakers to evaluate 3pl reverse logistics service providers. It supports them to visualize the intensity of the impact of various criteria on the alternatives available before reaching the final decision.

Recommendations

1. The study recommends increasing awareness on the level of green reverse logistics management practices in the Egyptian electronic waste supply chain; this will help reduce the disposal of mobile phone parts.

2. There is a need to adopt various grlm practices among the stakeholders in the egyptian mobile phone supply chain. There is a need to devise measures to reduce the challenges faced by stakeholders in the Egyptian electronic waste supply chain relating to green supply chain practices.

1) The importance of government support in the recycling industries for electronics and the provision of adequate facilities for investors to enter the recycling sector.

2) Qualifying specialized staff in environmental issues and taking advantage of their expertise in this aspect.

3) There is a need to enact and legislate a law prohibiting the export and recycling of electronic waste for use in the state.

4) The legislative framework for e-waste management that incorporates responsibilities to importers, manufacturers, and owners.

5) We need to enhance and collect accurate data on quantities and types of e-waste generated and appear in waste streams.

6) Need to enhance the participation of the concerned stakeholders in e-waste management.

7) Need to develop a proper collection, transportation, recycling, exporting, or disposal system.

8) Need to build local capacity/experts on e-waste management.

9) Need to identify recycling technologies for known e-waste stream.
