The R Strategies

One major characteristic of circularity is its capacity to manifest both as an operational scheme and a value system. It is pragmatic as much as it is idealistic. Take the R strategies for example: on the one hand, they propose concrete ways of either closing, slowing or even narrowing material loops. On the other, inherent to these strategies are the values of caring and sharing. These are expressed by either prolonging a material’s life cycle through repair or manufacture, or by intensifying a material’s use through rethink. Or in the more extreme cases, by even refusing to make use of a given material in the first place. In this video, Olga provides with an overview of the ten R strategies presenting the most dominant definitions of the Rs as well as their opportunities and their limitations.

Circularity for Educators

The platform is intended to provide with content on either circularity or pedagogy for and about circularity. It is one of the outcomes of the Circular Impulse Initiative (CII), a project intending to enhance the integration of circularity in the Faculty of Architecture and the Built Environment education. The platform mainly aims to help tutors get better acquainted with circularity in the built environment by providing a series of resources on this subject that they can either view to get better informed or directly share with their students in class or online. A large number of the Faculty's professors and researchers have contributed substantially both in creating a coherent narrative for circularity in the built environment as well as further elaborating on different aspects of it. Besides this one, a new platform for interaction and direct exchange was also established in parallel that we call ‘Educators for Circularity‘. This one offers the opportunity for all of us to meet and share our experiences and learn from one another.
