System change for the circular economy (CE) in the society requires innovative thinking in refining existing material into new resources and collaboration with different actors. We introduce examples of decomposers with different roles in a circular ecosystem. Examples from reusers of waste material, users of recycled materials, designers of new technologies, and facilitators of CE networks are introduced to illustrate how companies contribute to a circular ecosystem in the clothing and textiles industry. Moreover, we illustrate the networked nature of supply chains of circular materials.
