In class we learned that Industrial Symbiosis is when two or more companies exchange materials, products, or energy, to minimize as much waste as possible and to make these things into new products that could be sold. This reuse of materials will reduce waste and create as little pollution as possible. This industrial symbiosis relationship between companies creates a cycle where things that would typically become waste are given new life and create more profit instead of hurting the environment.
The article we read explores the different limitations of certain wastes and cases of industrial symbiosis within the Greek industry. This article identifies that there are certain limitations on waste’s ability to be reused due to location, cost, and physical material. The article separates these limitations into seven categories based on physical attributes; fuels, thermal energies, metals, plastics, chemicals, minerals, and organics.
Waste compatibility is a distinct factor due to the fact that the physical characteristics of some things are not as easily reusable as others. In the article, they give the example that agricultural waste such as yeast residues can easily be used for other agricultural activities, however, some wastes do not recycle as easily. Another factor is the spatial allocation as it is easier to recycle materials if there is somewhere to do so nearby. The article also talks about the importance of transportation cost and how this often will affect how easy it is for industrial symbiosis to happen.
Overall, according to the article, there are the economic factors such as spatial allocation of waste, production capacity of waste by spatial scale, land acquisition cost, labor cost, and transport cost. Then there are the environmental or physical factors such as the characteristics of waste and its compatibility. Finally, there are the social factors including conventional behavioral factors. The article goes on to conclude that for an industrial symbiosis economy to be possible, all of these factors must be considered and have to be used to design these networks and cycles.
The article concludes that doing this is often impossible, and while I believe this is likely true, I think it is still important to do our best to achieve our sustainability goals even if we do not completely hit the mark.






I appreciate the concept of a circular economy that nothing should be thrown away, as I myself try to waste as little as possible. The figure in the article that says one third of food produced for human consumption goes to waste is crazy to me as the world food program estimates 10% of the world is hungry and there is no reason for that much to go to waste. The same concept goes for clothes, our generation is constantly repurchasing clothes and keeping them for half the time that clothes were worn for before. This does not make sense because we have better technology now and clothes should be lasting longer, but fast fashion is taking over and this needs to be minimized as our world is dying around us.
