Towards implementation of circular building components: A longitudinal study on the stakeholder choices in the development of 8 circular building components

Implementing circular building components can contribute to the transition to a circular economy. There are many possible circular design options for building components. Knowledge on which options are feasible to implement remains limited. Existing feasibility studies do not compare multiple circular design options, building components and...

Re-organise: Game-Based Learning of Circular Business Model Innovation

This study furthers game-based learning for circular business model innovation (CBMI), the complex, dynamic process of designing business models according to the circular economy principles. The study explores how game-play in an educational setting affects learning progress on the level of business model elements and from the perspective of six...

Contaminated by Its Prior Use: Strategies to Design and Market Refurbished Personal Care Products

Refurbishment is an effective circular strategy to lengthen a product’s lifetime. However, refurbished products that are intimately used, such as personal care products, cause a feeling of unease in consumers because they are perceived to be contaminated. In 15 in-depth online interviews with female users of intense pulsed light (IPL) device...

Environmental design guidelines for circular building components: The case of the circular building structure

Transitioning to a circular built environment can reduce the environmental impacts, resource consumption and waste generation emanating from buildings. However, there are many options to design circular building components, and limited knowledge on which options lead to the best environmental performance. Few guidelines exist and they build...

A Circular Economy Life Cycle Assessment (CE-LCA) model for building components

The transition towards a Circular Economy (CE) in the built environment is vital to reduce resource consumption, emissions and waste generation. To support the development of circular building components, assessment metrics are needed. Previous work identified Life Cycle Assessment (LCA) as an important method to analyse the environmental...

Development of a life cycle assessment allocation approach for circular economy in the built environment

Transitioning the built environment to a circular economy (CE) is vital to achieve sustainability goals but requires metrics. Life cycle assessment (LCA) can analyse the environmental performance of CE. However, conventional LCA methods assess individual products and single life cycles whereas circular assessment requires a systems...

Navigating transitions for sustainable infrastructures - The case of a new high-speed railway station in Jingmen, China

Sustainable development and Circular Economy (CE) have drawn massive attention worldwide. Construction practices consume large amounts of materials, resources and energy. Sustainability and CE could play a big role in reduction efforts. However, the potential influence of both concepts on the planning and construction of large infrastructures...
