What Is a Closed-Loop Supply Chain and How Can it Help?

Shared from Revolutionized

Supply chains are one of the most crucial parts of running a successful business. At the same time, these networks are often the areas of greatest waste and most frequent disruptions. A closed-loop supply chain provides a potential answer.

Traditional supply chains move in just one direction, flowing from production to the consumer. Reverse logistics usually only comes into the equation when there’s an issue with the product, and these often end in waste. Closed-loop systems aim to combine the two supply chains to make a more cohesive, less wasteful network.

What Is a Closed-Loop Supply Chain?

A closed-loop supply chain uses reverse logistics to feed products that have served their purpose back into the forward logistics process. A manufacturer creates a product, ships it to customers, then encourages customers to return it once they no longer need it. These used products then become part of the manufacturer’s supply through repair, resale or component reuse.

These systems are an important part of the circular economy, which aims to eliminate waste. That waste reduction begins with closed-loop supply chains, as these use what would otherwise be waste as manufacturing supply.

These supply chains can operate in several ways. One of the most common methods is breaking down no longer functional products into their core components then using these recycled parts in new products. Other businesses may instead repair some products and resell them.

Hybrid systems may prove the most effective. Manufacturers can repair the products they can and recycle the ones they can’t. Using recycled parts from one product type in the production of another can also help maximize these systems’ efficiency.

Benefits of Closed-Loop Supply Chains

The closed-loop supply chain can be a complicated process to establish. Still, many companies are starting to implement these systems, as their potential benefits are impressive.

An efficient closed-loop system can help a business improve across multiple areas. Here are five of the most significant benefits of implementing a closed-loop supply chain.

Sustainability

The most easily recognizable benefit of the closed-loop supply chain is environmental sustainability. Most manufacturing processes take a substantial toll on the environment. Resource extraction and processing are responsible for 90% of biodiversity loss and water stress and 50% of global greenhouse gas emissions.

Considering the world recycles less than 9% of manufactured items, there’s abundant opportunity to improve. Closed-loop systems capitalize on these opportunities, reducing raw resource use by relying on recycled and reused products and materials.

As used products account for a larger portion of manufacturers’ material supply, related extraction and processing emissions will fall. Manufacturers will also be responsible for less waste, sending fewer products into environmentally damaging landfills. That’s particularly valuable for electronics producers, as e-waste produces harmful toxins into the environment.

Reduced Costs

This waste reduction also presents an enticing business opportunity for companies who embrace this system. Traditional supply chains’ waste represents a substantial monetary loss on top of being environmentally harmful. The clothing industry alone could generate an additional $500 billion if it moved away from under-utilization and recycled more.

Closed-loop supply chains reduce expenses by minimizing resource acquisition and processing costs. While reverse logistics and recycling aren’t cost-free, they typically cost less than acquiring raw materials, especially considering lifetime costs. When businesses reuse and recycle more, they stretch their raw materials further, becoming more cost-effective.

With the world recycling less than 10% of its products, there’s a significant economic opportunity that companies haven’t capitalized on. Feeding more products back into the supply chain could lead to substantial savings.

Customer Loyalty

The closed-loop supply chain also helps generate more customer loyalty, providing ongoing success. Sustainability is becoming an increasingly important issue to consumers. As this trend grows, companies that rely on traditional, environmentally destructive processes will fall out of favor and struggle to compete.

A 2021 survey revealed that one in three consumers have stopped purchasing some brands because of sustainability concerns. Similarly, 34% have chosen brands with environmentally friendly practices or values. Companies need to embrace sustainability to appeal to modern markets, and closed-loop supply chains provide a means to that end.

Businesses can see considerable reductions in solid waste, carbon emissions and habitat destruction by embracing closed-loop systems. Publishing these results can be an effective marketing strategy for an increasingly eco-conscious market. As more businesses take sustainability seriously, this will appeal to B2B markets as well.

Visibility

Implementing closed-loop supply chains can bring enticing indirect benefits, too. Supply chain transparency is a natural side-effect of closed-loop systems, as businesses will have to track products more closely to see opportunities for recycling and reuse. As they create these tracking systems, they’ll gain more control over their supply chains.

Visibility is a struggling point for many supply chains today. Only 6% of surveyed companies say they have full visibility into their supply chains. As a result, they may not be able to react to incoming disruptions and delays in time.

As companies track product lifecycles through closed-loop systems, their overall transparency will improve. They’ll gain more insight into product demand cycles, supply chain issues and trends that impact their efficiency. They can then take these insights to fine-tune their supply chains to become more productive and resilient.

Preparing for Future Regulations

Right now, the environmental benefits of closed-loop supply chains provide a competitive advantage. However, they could become a necessity in the future as environmental regulations tighten. Pursuing closed-loop systems now can help businesses anticipate this shift and meet future regulations before they present a challenge.

Regulatory landscape across the globe is trending towards sustainability. For example, the UK aims to recycle 65% of municipal waste by 2035. As similar trends arise, companies may have to recycle or reuse a certain amount of their waste or face fines in the future.

Adopting waste-minimizing practices now can ensure businesses face minimal disruption when regulations like these come about. They can then pull ahead of the competition that may face greater disruption in adapting to these requirements.

Examples of Closed-Loop Supply Chains

The closed-loop supply chain exists in more than just theory, too. As these benefits have become clear, several companies have started to embrace closed-loop systems. While they may not have perfect circular economies, they do rely on several key closed-loop features.

For example, more than 75% of Nike products contain recycled textiles as of 2018. Some of their products consist mostly of recycled materials, something they’ve achieved by switching to processes that make some materials more easily recoverable. These efforts have helped some facilities divert more than 95% of their waste from landfills.

Some closed-loop supply chain systems involve multiple companies to let waste from one area feed into production in another. The Farm Powered Strategic Alliance, which involves companies like Starbucks and Unilever, diverts food waste to businesses that turn it into a renewable energy source.

Challenges With Closed-Loop Supply Chains

While closed-loop supply chains have many substantial advantages, many companies are still hesitant to embrace them. Several obstacles remain that make them difficult to implement. The cost of implementation is perhaps the most significant of these challenges.

Many products are not easily recyclable. The materials and processes manufacturers use can make it difficult to recover much from a used item. As a result, it may require excessive costs to recycle waste, and businesses may not recover enough material to offset these costs.

Establishing an efficient reverse logistics system can also be challenging and incur high costs. Transportation costs will rise to bring old products back to production facilities, and technology expenses will rise as tracking systems expand. While reduced waste may offset these expenses over time, the initial financial burden may be too much for some companies.

Supply Chains Must Evolve

Creating a closed-loop supply chain may be challenging, but it may also be a necessary step forward. Supply chains must become less wasteful and more efficient to protect the environment and meet modern businesses’ needs. Closed-loop systems enable that.

As more businesses invest in closed-loop systems, optimal strategies will emerge, and the process will become less challenging. The world’s supply chains can then become more eco-friendly and cost-efficient.
