The FISSAC project involves stakeholders at all levels of the construction and demolition value chain to develop a methodology and software platform, to facilitate information exchange, that can support industrial symbiosis networks and replicate pilot schemes at local and regional levels. The model will be based on three sustainability pillars: Environmental, Economic and Social. The project's ambition is that the model created can be replicated in other regions and other value chain scenarios. FISSAC aims to demonstrate the effectiveness of the processes, services, and products at different levels.
