This report describes a number of different elements of work being undertaken in a project entitled 'SRUC-C4-1: Building the circular economy: sustainable technologies, green skills and upscaling behaviours', including on-the-ground fieldwork in the islands of Arran and Cumbrae in North Ayrshire, Scotland and international case study based evidence gathering. Based on this evidence the report draws some early conclusions regarding the feasibility of circular economy initiatives in island locations.
