Circular economy practices are gaining importance in the global textile and apparel value chain. However, the circular economy's social dimension is often overlooked.

To address this problem, this study develops transformative circular futures (TCFs), co-created circular economy scenarios that are diverse and systemic and embed social impact considerations. The aim is to inform policy and business decision making in the textile and apparel value chains of India, the Netherlands and Spain.

The study recommends normalising living wages for direct, indirect and informal workers, implementing regulations challenging the patriarchy, eliminating gender pay and establishing permanent global committees of social actors.

Companies in the textile and apparel value chain have been increasingly implementing circular economy practices. However, implementation has focused on the techno-environmental (hard) dimension, and partly overlooked the (soft) social dimension. There is a lack of empirical knowledge about how businesses in this value chain simultaneously manage soft and hard aspects of circularity and what kind of socio-environmental impact they generate.

This research analysed the soft and hard aspects of ten circular business cases from three countries. It demonstrates that both aspects are integral components of a comprehensive transformative circular transition framework that facilitates the adoption of more inclusive and circular practices while improving sustainability performance.

This paper reviews digital tools that support the transition to a circular economy in the built environment. 

It explores how computer-aided design, building information modeling and computational plugins can assist architects and engineers in creating more sustainable buildings. While Life Cycle Assessment (LCA) remains the main approach for evaluating environmental impacts, the study highlights other methods and tools that can help assess circular design strategies, such as computational methods to design with reused elements and circularity indicators. The paper identifies both the strengths and limitations of these digital tools. 

This research is useful to academics and to practitioners designing buildings aligned with circular economy principles.

Concrete accounts for 8% of the world's CO₂ emissions. Efforts are being made to reduce its embodied carbon, but reusing concrete from existing buildings has significant untapped potential.

This study presents an innovative digital workflow for predicting the lifespan of concrete elements, CO₂ uptake via natural carbonation and embodied carbon savings through reuse. The workflow was tested in a building from the 1960s with high reuse potential. 

It found that most precast elements would last long enough to be reused effectively and that reuse is better for the environment than carbonation.

The digital workflow is useful for quickly assessing lifespan, carbonation and embodied carbon of concrete. It is a useful tool when designing for reuse.
