Shoes made from ocean plastics, packaging material made from mushrooms and a green partnership between Ford and Heinz to build car parts from tomato fibre are examples of the circular economy in action.
In a traditional linear economy, materials flow in a line; they are taken from the earth, made into an item in an affordable way, and waste goes into landfills when we are finished using the product. Circular economy has been inaccurately referred to as “recycling on steroids”. It was shown to be much more in an impactful presentation by United States based supply chain specialist Deborah Dull at the recent SAPICS Conference in Cape Town. She contends that supply chain management - and the circular economy - can save the planet. In her current role as Principal, Supply Chain Management, at General Electric subsidiary GE Digital, Dull works across the supply chain community to accelerate the transition to a circular economy. Her goal is to progress past a linear “take-make-waste” approach to one in which supply chains around the world are supporting a “make-reuse circular approach to dramatically lengthen the lifecycle of the items around us”.
“Circular economy is already well under way around the world and goes beyond sustainability agendas,” Dull informed delegates in her presentation at the annual SAPICS Conference, which this year attracted some 800 supply chain professionals representing 28 countries.
“The circular economy builds on the idea of industrial symbiosis where the idea is that a series of factories are set up next to each other; the biproduct or residual product of one factory process is used as a resource by another. Through local collaboration, public and private enterprises buy and sell residual products from one another, both making money and saving the environment. With new Industry 4.0 technologies, the concepts beyond the industrial symbiosis can be stretched across digital supply networks, allowing for materials and byproduct exchanges to happen at scale.”
Organisations and governments are investing in these initiatives because of the capabilities of the circular economy, including profits, she said.
Challenging the misconception that saving the planet always comes at a cost, Dull reported that the circular economy is on track to add USD4.5 trillion to the global economy by 2030 and create hundreds of thousands of new jobs. “I argue that the true focus of circular is first on the ‘economy’ part; on expanding profits,” she stated.
Sports brand Adidas is embracing circular economy principles in its partnership with “Parley for the Oceans”, an environmental organisation that is fighting environmental threats posed by ocean plastic pollution. “In 2017, Adidas sold one million pairs of its Parley brand shoes, which are made with ocean plastic. In 2018, five million pairs were sold; and Adidas has announced that it will make 11 million pairs in 2019. These are not inexpensive shoes, but they are in demand,” Dull said.
Proctor & Gamble is making bottles from recycled plastic and ocean plastic. “As part of their ‘Ambition 2030 Initiative’, they have taken nearly all of their manufacturing facilities past zero waste towards circular models and have saved over USD2 billion.”
She revealed that there is growing emphasis on designing products for the circular economy. EcoCradle is one such product. Designed to replace Styrofoam, it is a mushroom-based packaging material that is now being used by furniture giant IKEA. “It grows relatively quickly. It is cost effective; and it decomposes in 30 to 90 days,” explained Dull, adding that the global market for sustainable packaging is expected to reach more than USD140 billion in coming years.
The circular economy highlights the importance of extending the useful life of an item for as long as possible. This has increased “Product as a Service” offerings across the market, such as Uber, US-based “Rent the Runway” clothing rental, and – for an industrial example – “time on wing” for airplane engines. Dull explained that GE Aviation offers this time on wing through an “Outcome as a Service” offering to airlines, which means GE Aviation is responsible for predictive and preventative maintenance. “This is important, because assets are smart. Machines are intelligent. The Industrial Internet of Things and Industry 4.0 are bringing together sensors, advanced analytics, and machine learning. This combination means that the engine tells us when it needs to be serviced. And, as you can imagine, this is very powerful.” Maintenance, Dull explained, is a key enabler of the circular economy.
Dull finished her presentation by exploring the impacts of the circular economy on the supply chain, asking delegates to imagine waste as something of value that will be exchanged among supply chains as input to products and processing.
With materials exchanges starting to emerge across the world, Dull showcased early examples of “parts passports”, which record an asset’s details and history, including market analysis for valuation, and pair up potential buyers and sellers. “We need to start thinking about waste as inventory. Consider how much of the circular challenge could be solved if everyone switched, tomorrow, to using recovered materials only – and no longer used new, virgin materials,” she challenged.
At circular economy forums around the world, supply chain professionals are missing from the conversation. Dull concluded by urging SAPICS delegates to “invite yourselves to the discussions; supply chain teams find solutions to impossible challenges across the world. Now is the time to come together as a global community and create supply chains that can support circular business models”.
Established 40 years ago, the SAPICS Conference is the leading event in Africa for supply chain professionals. It is hosted annually by SAPICS, The Professional Body for Supply Chain Management.
