Exploring the emergence of waste recovery and exchange in industrial clusters
Journal of Industrial Ecology, Volume 27, Issue 3, Page 937-950, June 2023., 2023 Abstract Self‐organized industrial symbiosis (IS) starts with one actor's decision to invest in a waste recovery plant and the other actors' decision to buy the recovered flow. Technical and institutional conditions of the cluster influence actors' decisions.
