Manufacturing is vital to our lifestyle. With out it, we’d not have the provides, meals, clothes, electronics and different issues we use on daily basis. Nevertheless, manufacturing additionally produces waste that usually leads to landfills or oceans.
Taking a look at pure ecosystems supplies a unique perspective on this conundrum. There may be little or no waste in nature. For instance, sure micro organism and fungi decompose useless natural matter, reintroducing vitamins again into the soil for vegetation to make use of as they develop.
This evokes the query — what if one producer’s trash may very well be one other one’s treasure?
Corporations might save on waste disposal and uncooked materials sourcing prices. Our planet would additionally profit by preserving probably precious supplies out of landfills.
For instance, many corporations don’t want pristine or drinkable water for his or her manufacturing processes. So, quite than discarding used water, one other firm can use that water for its personal operations. This idea of useful resource sharing and waste change by mutually useful partnerships is named industrial symbiosis.
Industrial symbiosis preparations enable corporations situated close to one another to share sources simply due to their proximity. For instance, the prices to move supplies between totally different companies will presumably be decrease in the event that they’re close to one another.
Industrial symbiosis is already being utilized in some elements of the world. The Kalundborg Industrial Symbiosis in Denmark is a well-known instance of this strategy. During the last 50 years, the Kalundborg partnerships have grown organically by elevated consciousness of their financial and environmental advantages. At the moment, 17 associate companies are exchanging greater than 30 various kinds of supplies, reminiscent of water, sand and ethanol waste. As of 2020, the symbiosis had reportedly saved 4 billion liters of groundwater. This partnership decreased a lot waste that the native vitality provide has grow to be carbon-neutral.
Nevertheless, not all makes an attempt at industrial symbiosis have been as profitable. There are a number of challenges to rising these initiatives. These embody the notice and identification of appropriate waste change streams, contract negotiations amongst corporations, and a lack of understanding of what makes the preparations profitable. That’s why I joined the manufacturing in a round financial system analysis group at NIST as a postdoctoral researcher to know what makes these networks profitable and the way we are able to measure their success.
Engineering Requirements for Industrial Symbiosis
Industrial symbiotic partnerships, reminiscent of these highlighted within the Kalundborg instance, have been acknowledged in a brand new worldwide commonplace as an vital step in making our financial system extra round. Now greater than ever, it is vital that we develop metrics and analysis strategies to know the well being and viability of these kinds of partnerships.
Corporations considering industrial symbiosis need to know the way it will profit them and if the hassle might be price their time and monetary funding. Moreover, if a enterprise can divert waste utilizing one in every of these partnerships and a neighborhood authorities needs to reward it with a tax break, that authorities would need to know the corporate is assembly its acknowledged sustainability targets.
However earlier than an ordinary could be created, we have to research the issue. That’s the place our group — together with different researchers — is available in.
I lately studied varied examples of real-world industrial symbiosis initiatives — each newer and extra established efforts. My purpose was to see what I might find out about what makes such a mission profitable. Evaluating these applications permits the organizations operating them to be taught from the most effective practices and experiences of others.

Our work was lately printed within the Journal of Cleaner Manufacturing, which mentioned seven components that have an effect on the success of those preparations.
For instance, profitable, long-term industrial symbiosis initiatives reuse considerably extra supplies than newer partnerships do. It’s not shocking that the extra corporations profit from these preparations, the extra seemingly they’re to remain in them for the long run, and that’s higher for sustainability.
Moreover, we studied the cohesiveness of the networks, particularly, how tight or free their ties are to one another. Let’s say there’s an industrial symbiosis mission in an space with one useful resource provider and three shopper corporations that provider sells supplies to. If that one provider firm leaves the partnership, the three shopper corporations may additionally go away as a result of they haven’t any relationship with one another and no cause to work collectively.
Extra mature industrial symbiosis networks, in distinction, had extra tightly related organizations with a number of totally different partnerships amongst each other. Newer ones had fewer partnerships and looser ties.
Our analysis confirmed that we are able to research the traits of corporations that make industrial symbiosis profitable with no need entry to delicate, proprietary firm data. This implies corporations can be happy to take part in future analysis like ours — which we finally hope will assist make our financial system extra round — with out compromising their enterprise.
Changing into a Sustainability Researcher
Sustainability and resilience are advanced and multifaceted, and so is researching these subjects. It’s not simply science but in addition math, economics and even a little bit of sociology. Sustainability analysis provides me the chance to make use of my curiosity for arithmetic and apply it to handle advanced, real-world challenges.
Throughout my undergraduate training, I did internships at Georgia Tech, engaged on manufacturing strategies for hydrogen gasoline cells. This expertise additional motivated me to pursue graduate analysis in sustainability and local weather change.
I additionally benefit from the extremely collaborative nature of this analysis. That’s a necessity due to the interdependencies between varied areas of our human-created atmosphere, reminiscent of manufacturing, vitality and provide chains.
Actually, my entry level into industrial symbiosis analysis was by a collaborative mission! On this mission, a colleague and I demonstrated a novel strategy to industrial symbiosis partnerships that cut back consumption and companies’ working prices.
Since I’ve arrived at NIST as a postdoctoral researcher, I’ve gotten concerned in service and management roles inside the sustainability and resilience analysis neighborhood. This 12 months, I led the group of a panel dialogue with eminent specialists within the areas of round financial system and sustainable manufacturing on the 2024 American Society of Mechanical Engineers’ Manufacturing Science and Engineering Convention.
An vital takeaway from that dialogue was the significance of utilizing sustainability analyses early on in an engineering mission so we are able to higher perceive the bigger-picture environmental influence of seemingly small selections, reminiscent of selecting supplies for a product.
Wanting Forward to an Industrially Symbiotic Future
The alternatives to work with a various group of practitioners and researchers encourage me to proceed studying and advancing this discipline. I hope to proceed working in infrastructure sustainability and resilience analysis and implementation going ahead in my profession.
I hope that our research and future research like it can assist to scientifically exhibit what makes industrial symbiosis teams profitable. Over the long run, this might result in requirements that might enable corporations to know the place to take a position to advance their enterprise and promote sustainability for everybody.
Making our financial system extra round is a big, advanced problem. Nevertheless it’s thrilling to look to nature for inspiration on how we are able to preserve supplies in use indefinitely — benefiting each folks and the planet.
