In the recent online CORALIS workshop with H4C Community of Practice, which took place on Tuesday 12th December 2023, participants gained valuable insights from the experiences of the CORALIS project in implementing industrial symbiosis. The workshop, led by notable presenters including Sebastian Engell, Manuel Gomez Perez, Danna Person, Daphne Mirabile and Johannes Lindorfer, explored various aspects of industrial symbiosis and showcased practical examples from different regions.

The event commenced with a warm welcome and an introduction to the H4C Community of Practice, emphasizing the importance of collaborative efforts in achieving the targets for climate neutrality and circularity by 2050. Then there was an introduction to the CORALIS project which set the stage for the subsequent discussions, providing context to the challenges and opportunities in the decarbonization of resource and energy-intensive sectors.

The workshop highlighted specific case studies, specifically 2 of the lighthouses of the project: Regenergy Frövi project in Sweden, which focuses on low-grade temperature waste heat recovery from the pulp and paper industry as well as the Brescia district, which explores the valorization of residues from the steel industry, shedding light on sustainable practices and circular economy initiatives.

The presentation then shifted to the CORALIS follower cases in Basauri (Spain), Linz (Austria), and Izmit (Turkey), providing valuable lessons learned from these diverse cases.

Throughout the workshop, the speakers engaged in question-and-answer sessions, providing participants with the opportunity to delve deeper into the presented topics and gain a comprehensive understanding of the challenges and successes encountered in the field of industrial symbiosis.

In essence, the workshop served as a platform for knowledge exchange and collaborative learning, contributing to the ongoing efforts to accelerate the transition to industrial symbiosis, industrial-urban symbiosis and circular economy practices. The presentations and discussions further underscored the importance of shared resources, experiences and tools in progressing towards a sustainable and circular future.
