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.

Circular Sweden

Sweden aims to have gone circular by 2030.

Circular Sweden wants to help deliver on this goal. It is a corporate forum keen to make material flows more circular. 

It focuses on technological development, consumer behaviour and policy, against the backdrop of circular design, sustainable consumption, increased access to and use of recycled materials, and circular value chains. Circular Sweden is a forum where businesses, policy makers and researchers can discuss obstacles and opportunities.

Its members influence major material flows or are active in enacting circularity. It organises roundtable conversations, reports and media activities. Workshops and strategy meetings aim to create synergies, spread good practices and find ways for companies to create more circular material flows.
