SirkTRE’s Evolution or Circulution? Diverse Pathways of Circular Systemic Solutions for a Net-Zero Timber-Built Environment

The Norwegian innovation and action project SirkTRE is halfway through. In recent years, it has been increasingly recognized that circular wood solutions for construction solutions are often technically feasible; this is particularly underscored by the SirkTRE project (2022–2025). However, the scaling up of these solutions and their interaction with various barriers underscore the necessity of systemic approaches. This chapter delves into selected circular systemic solutions derived from the project. This collaborative autoethnography, drawing insights from observations and reflections on own experiences, takes an evolutionary approach to selected SirkTRE solutions. The case studies within SirkTRE include solutions at the manufacturing level, the architectural product-system level, and the building-site level and strategies engaging municipalities to supply and utilize reclaimed timber in (especially public) buildings. These examples illustrate not only the successes but also the challenges, including how economic, political, technological, and strategic decisions can impact the scaling up/out or ending. To catalyze a true revolution, or ‘circulution’, it is imperative to integrate governance, and business models, to foster interactions in the emerging system.
