Efforts geared towards sustainable development have been progressing in different fields, recently shaping a transitional framework named Circular Economy. In a similar manner, design has produced a collection of significant results, some of them formed the field known as Design for Behaviour Change. This field has produced a series of strategies, models, tools, and methods, by bringing knowledge from the social sciences into design. This project sets out to investigate the scope and limits of one tool in particular—Dimensions of Behaviour Change—by formulating the research question: To what extent, Dimensions of Behaviour Change tool—DBC model—can be used in design practice to generate solutions that foster recycling behaviour within Circular Economy framework? The answer is unraveled in this thesis comprised of five main phases: introduction, literature review, methods, study, and results. Ultimately, attempting to contribute to the progress of this field.
