Símbiosy is a consultancy company that acts as a facilitator in industrial symbiosis projects, providing territorial entities with the tools and the methodology to implement circular economy strategies and identify synergies among key stakeholders within a network (companies, public authorities, research institutions, etc.). The overall goal is to improve the resource efficiency and the competitiveness of the industry sector. As a result of years of experience facilitating industrial symbiosis projects, the team at Símbiosy has developed a methodology to launch and promote circular, collaborative projects, which serves as a facilitation/implementation guide addressed to any coordinating entity of industrial symbiosis projects. Facilitating and managing industrial symbiosis projects involves analysing the industrial ecosystem, identifying potential network synergies, engaging and building capacity of key stakeholders, facilitating collaboration among them, and creating a common action plan, which is always followed by a monitoring process for each of the industrial symbiosis projects. This ensures a proper comparison and quantification of the network performance.
