Recycle! – An Exhibition on Circular Architecture and Reused Materials
The exhibition Recycle! in 2025 explored how reuse and circular materials can become part of architecture’s aesthetic. The exhibition itself was built on reuse: everything was registered down to the smallest screw and the scenography reused materials from previous DAC exhibitions.
Everything we build has value – even after it has been used. How can we rediscover the beauty of reuse and create a future where used materials gain new life and circular resources take on new value? How can reuse become part of architecture’s aesthetic? What does architecture look like if we stop throwing things away?
Construction is one of the world’s biggest climate offenders. We build, demolish, and discard resources as if they are infinite. But a new movement is gaining ground—we are starting to build circularly. Across different places, design and construction are being reimagined to make use of what already exists. More buildings are being preserved, and repurposed materials are finding new functions.
But how do we make reuse the most attractive choice in architecture? What does the future of architecture look like if we no longer see building waste as waste?
This exhibition presented architecture that challenged the way we build. You could see how concrete from demolished buildings was reborn in new structures. Feel how reclaimed wood found new life in modern architecture. Experience installations that revealed the beauty of imperfection.
To change the way we build, we must rethink—together. Architects, engineers, and artists are developing solutions that are both functional and beautiful. But this transformation also depends on you. Only when we all recognize the value of preserving and repurposing materials can we truly change the future of architecture.

Reuse is not just a necessity – it is an opportunity
In this exhibition, you could discover how we can build smarter, more beautifully, and more sustainably by working with what we already have.

Experience a piece of Børsen in the exhibition
When the Old Stock Exchange burned down, we lost a 400-year-old national treasure. The fire and the now towerless ruin evoked strong emotions and reminded us that bricks can hold a story.

An exhibition built on reuse
As you moved through Recycle!, you stepped into a hands-on example of circular exhibition design. Every single detail – right down to the last screw – was tracked and ready to be reused. The scenography was built from elements used in previous DAC exhibitions, and even mattresses, podiums, and signage had been repurposed. One installation from the former exhibition Water is Coming by architecture studio MAST lived on as a poetic rest area in the exhibition.
This was all part of DAC’s commitment as a certified Green Attraction – where sustainability isn’t just on display, it’s part of how we build.

The rebuilding of the Stock Exchange will be one of the largest reconstruction projects in Danish history. Over the next seven years, architects, craftsmen, and engineers will work to revive one of Copenhagen’s oldest landmarks by reusing bricks and iron fittings and bringing old craftsmanship traditions and mortar recipes back to life.

Nearly 60 years after its construction, the industrial building at Thoravej 29 in Copenhagen’s Nordvest district has undergone an ambitious and extensive transformation focused on sustainability. Instead of being demolished and replaced with new construction, the building has been reimagined in a way that points toward the future.

TRÆ in Aarhus is a groundbreaking example of how recycling and sustainable choices can create a new aesthetic that both respects the environment and challenges our perception of building design. Instead of designing the building first and then selecting materials, the architects reversed the process: they identified available recycled materials and created the structure accordingly.

See Our Current ExhibitionsWhat was Recycle!?
Recycle! was an exhibition about circular construction and material reuse, asking how reuse can become part of architecture’s aesthetic and what architecture looks like when we stop throwing materials away.
When did Recycle! take place?
The exhibition ran from 11 Apr to 10 Sep 2025.
What materials and approaches did the exhibition highlight?
The exhibition highlighted concrete from demolished buildings reborn in new structures, used wood given new life, and installations that revealed the beauty of the imperfect.
What does “an exhibition built on reuse” mean in practice?
Everything in the exhibition was registered down to the smallest screw so it could be tracked and reused, and the scenography was made from materials from previous DAC exhibitions, with items like mattresses, podiums and signs repurposed.
What is the “piece of Børsen” mentioned in the exhibition?
Visitors could experience a piece of Børsen, linking it to the fire and the idea that there can be “soul” in bricks.
What should I know if I only read one thing?
Recycle! (11 Apr–10 Sep 2025) was about making reuse attractive in construction—and it demonstrated circular practice by being built from reused elements that were registered and designed to be reused again.
This exhibition is developed by Danish Architecture Center
