Components of the circular city implementation framework
The four components listed below constitute the key components in the circular city implementation
framework. They are the necessary components for implementing circularity in cities.
– City assets and products – encompass various city infrastructures, city resources, city goods and
services available for use/consumption in the city.
– Circular actions – specific, outcome-orientated actions that can be applied to city assets and
products that include sharing, recycling, refurbishing, re-using, replacing, and digitizing.
– Circular city outputs – they are the results of when circular action items are applied to city assets
and products.
– Circular city enablers – various supplementary and complementary items that are used to catalyse
and support circular city outputs.
3.1 City assets and products
Figure 1 presents various city assets and products. They are classified into three categories: city
infrastructure, city resources, and city goods and services (as potential inputs to circular action items
described in sub-section 2).
