CityLoops wants to ensure the economic viability of its demonstration actions, and provide a strong rationale for upscaling at regional level and replicating elsewhere in other cities. This is why it aims to back the demonstration actions in both waste streams with strong business cases. In the case of bio-waste, they are the following:
- In Apeldoorn, sound business cases for each of the five demonstration actions will be developed: bokashi production from leaves, biochar production, production of fibre-based products, 3D printing with organic fibre and municipal cleaning of grass.
- In Mikkeli, business cases will be developed for three types of end-product: bio-methane (for transportation), fertiliser and soil improvement products. These business cases will look at markets for these products, regulatory framework and will examine the economic viability of their production at commercial scale, in collaboration with local stakeholders. Mikkeli will also analyse business cases underlying different separated collection and logistics systems, looking specifically at nutrient recovery potential based on the current estimated volumes of biowaste in municipal solid waste, and nutrient content in biowaste as well as other issues affecting profitability of biowaste collection, such as logistics and separated collection systems in sparsely populated area.
- Porto and Seville are not developing business cases for their bio-waste demonstration actions. However, in Porto economic viability will be a key concern for demonstration actions, and the city will also foster the circular transition of its local ecosystem through the organisation of a Contest for Circular Ideas, where five winning ideas will be turned into fully viable circular business models.
