Introduction to Creating a Circular Supply Chain
Supply chains have traditionally been linear, with materials and products moving in a one-way path from manufacturers to consumers. However, there is growing recognition of the environmental and economic benefits of transitioning to a circular model where items are kept in use for as long as possible. In this article, we will discuss the principles of a circular supply chain and provide practical strategies for companies to begin implementing circular practices.
Moving Beyond a Take-Make-Waste Model
The linear “take-make-waste” supply chain has severely strained our planet’s finite resources. By some estimates, we are extracting over 100 billion tons of raw materials each year and only 9% of plastic is recycled globally. This model relies on consuming ever greater amounts of virgin materials and is not sustainable. A circular supply chain aims to redefine growth and shift businesses away from this throughput model towards one that is regenerative by design (Ellen MacArthur Foundation, 2015).
Rather than treating materials and products as disposable, a circular model keeps components and materials in use at their highest value for as long as possible through reuse, remanufacturing, refurbishing and recycling. When products reach the end of their useful lives, their materials are recovered and regenerate back into the production cycle. This minimizes waste and pollution while unlocking new sources of value and competitive advantage for companies.
Designing for Circularity
To enable effective circulation of resources, companies need to design products with consideration for future disassembly, reuse, remanufacturing and recycling from the outset. Three key design principles for circularity are:
- Modularity – Products should be designed with standardized, interchangeable components so they are easier to take apart, repair and upgrade individual parts. This extends product lifetimes.
- Durability – Using durable, high-quality materials and construction means products last longer before needing to enter the after-sales chain. Components should be designed to withstand multiple lifecycles.
- Disassembly -Products must have designs enabling easy dismantling at the end of their lifespan, using simple, commercially viable processes such as snap fits and screws, instead of gluing or welding components together. This facilitates the separation and purification of materials at the end of each use cycle.
When considering a product redesign, mapping the material composition and flows from sourcing through end-of-use stages helps pinpoint where opportunities exist to close resource loops. Strategies like incorporating recycled content or using fewer toxic materials improve circularity as well as customer and societal value propositions.
Enable Sharing & Reuse Platforms
New digital platforms are helping enable more sharing and reuse of products. Renting or leasing durable goods like cars, power tools, or construction equipment enables optimized usage compared to individual ownership arrangements, as these items are often underutilized much of the time.
Platforms like bike-share programs or tool libraries enable sequential product loans, extending lifetime value. Companies can partner with or launch such programs to shift from ownership to usership models. Appropriate pricing, cleaning, maintenance and upgrade protocols ensure safe circulation of shared products.
Close Material Loops Through Remanufacturing
Another way to prevent valuable components from becoming waste is through remanufacturing – rebuilding products or components to original specifications using reused, repaired and replaced parts. The remanufacturing industry is growing rapidly with annual global revenues projected to reach $53 billion by 2025.
Core components like automobile engines, construction equipment transmissions or printer cartridges can go through multiple remanufacturing cycles, providing an alternative to manufacturing with virgin materials. This process significantly reduces energy and water use compared to producing entirely new components. Firms can expand remanufacturing offerings for various product categories to derive more value out of returned inventory.
Clear labeling to identify reusable core components and establishing dedicated collection, inspection and reconditioning infrastructure facilitates scaling up of remanufacturing as a supply chain activity. Contracts with new customers for remanufactured goods ensure offtake and help recover more value from returned assets.
Developing a Robust Reverse Logistics Network
For implementing any circular business model at meaningful scale, companies require an advanced reverse logistics network to efficiently transport, sort and process returned products and materials. Building out collection networks through distributors, independent operators or take-back partnerships brings inventory efficiently into the technical or biological cycles.
Deploying advanced sorting technologies, along with uniform item labeling and databasing helps in automatic identification and separation of reusable, remanufacturable or recyclable components. Establishing dedicated sorting and testing facilities close to consumption clusters minimizes transportation distances. Regional consolidated centers then transport materials to respective resale, repair, recycling or refurbishing facilities.
A responsive reverse logistics function closes resource loops while yielding cost savings from better identification and routing of reusable assets. Applying process automation, RFID tracking and utilization of intermodal freight helps optimize the reverse network.
Empowering a Warehouse Ecosystem for the Circular Economy
To effectively scale circular practices, collaboration across the entire supply chain becomes essential. Warehouses are key hubs where returned products are consolidated, sorted, and readied for reintroduction into supply chains.
Modular warehouses with optimized disassembly equipment facilitate smooth transitions of components and materials between cycles. For instance, dismantling facilities may send reusable plastics back into manufacturing while compostable materials go for organic recycling.
Investing in employee upskilling and providing performance incentives for achieving resource productivity and circular KPIs helps align warehousing operations. Partnering with material brokers expands options for finding high-value end markets for both virgin and recovered feedstocks. Emerging technologies like autonomous mobile robots and AI/ML accelerate processing and tracking of items within circular distribution centers.
Empowering warehouses with sorting, testing, refurbishing, and repackaging capabilities supports the circular economy’s infrastructure. Matching supply and demand also plays a crucial role.This enables manufacturers to efficiently manage reverse flows while focusing on product development.
Measuring Progress and Overcoming Barriers
Transitioning to fully-circular supply chains requires ongoing measurement, accountability and multi-stakeholder coordination. Adopting metrics like material reuse/recycling rates, % revenues from remanufactured/refurbished sales or CO2 savings allows quantifying benefits. Publishing performance through sustainability reports helps benchmark progress over time as well as across industry peers.
Implementing digital platforms to map material/component flows offers full traceability. Surveys cited initial costs, lack of infrastructure, and inability to capture lifecycle data as key barriers. Addressing these requires public-private partnerships for R&D, standards development, and pilot projects demonstrating technical and commercial viability at different scales.
Government policies favoring circular procurement criteria as well as EPR regulations on producers further accelerate systemic shifts. With collective efforts across the value chain, the transition to circular supply networks can move us closer to a thriving regenerative economy.
Conclusion
In closing, transitioning to circular supply chain models requires coordination and partnership across industry, government and communities. However, the rewards of doing so go beyond environmental sustainability – it leads to opportunities for innovation, new revenue streams and cost reduction. Companies that get ahead of regulations and shifts in consumer demand by designing products with future disassembly and redistribution in mind gain competitive advantage. While the path ahead involves overcoming initial hurdles, even small pilot projects demonstrate the viability of circular approaches. With committed efforts to measure impacts and collaborate on infrastructure development, more industries can transition from linear to circular flows that optimize resource productivity over the long run. By implementing strategies discussed in this article, supply chain leaders can make significant progress in closing resource loops and building supply networks fit for a regenerative economy.
