Publisable summary: Even though the concept industrial symbiosis (IS) has been around for decades there are still challenges that organizations need to overcome for its development and implementation. Early on within the Coralis project (within D3.1) efforts to identify scope of existing tools with the scope of supporting the development of IS was made. One important conclusion was that the majority of tools that are available today overlooks that the development of IS is dependent on human interactions and initiatives. Therefore, more effort should be placed on developing tools that encourage involvement of stakeholders and support collaboration between different areas of expertise and can support the “intensively human activity”1 that characterises IS scale up. Given the above, the IS System model adapted to Virtual Assessment Platform (henceforth referred to as the reduced order model or ROM) was developed to give a user-friendly model for exploration of different scenarios related to the Swedish IS case. A key aspect to this is to enable easy adjustment of parameters and instant results generation so the model can be used in collaborative contexts. For example, the model can be employed during stakeholder meetings, involving growers or investors.
