Advancing circular innovations via Drastic—Produktif celebrated at 2025 Green Solutions Awards
Green Solutions Awards Ice box Challenge winner.
Drastic partner, Produktif, earned major recognition at the Green Solutions Awards 2025 for their work on the 2024 Ice Box Challenge in Oslo, Norway, winning the National Award for Infrastructure and receiving a special mention for the Sustainable Infrastructure Grand Prize.
They also advanced to the international round, joining 60 finalists showcased at COP30 in Belém, Brazil, highlighting the international relevance of emerging Drastic innovations.
Produktif’s Ice Box Challenge entry demonstrated some of the key circular innovations shaping Drastic. Using their patented Design for Assembly and Disassembly (DfAD™) technology and C-Joint system—both featured in Drastic’s Norwegian Demonstrator—they built a highly efficient Passive House mini-home from reclaimed wood supplied by fellow partner, Omtre.
In a direct comparison with a standard-code house, the Passive House retained 150 kg of ice after 33 days of Norwegian summer heat, while the standard-code house’s ice melted completely after just 11 days. The result showcased the outstanding insulation performance and circular design potential of Drastic-aligned construction methods.
These achievements underscore how Produktif’s real-world testing and innovative design are advancing Drastic’s mission to accelerate European circularity.
Congratulations Produktif!

Meet the Demonstator
Drastic’s Spanish Demonstrator aims to establish a viable system for disassembling and reusing structural steel elements, for which no established ecosystem currently exists. It also seeks to repurpose white slag—a by-product of secondary steelmaking—as an alternative supplementary material in concrete to partially replace cement.
Led by the Celsa Group, with support from Lezama Demoliciones, Adec Global, the Polytechnic University of Catalonia (UPC), and Sorigué, this Demonstrator is located at Sorigué’s facilities in Balaguer, Spain.
Adec Global will tackle the pre-processing of the white slag, while UPC and the Celsa Group will conduct quality tests and determine the optimal substitution rate of white slag in place of clinker (the main component of cement), to ensure the material performs safely and effectively.
The project will culminate in the construction of a circular warehouse that incorporates reused structural elements from the dismantled Litoral Thermal Power Plant in Almería, Spain, deconstructed by Lezama Demoliciones.
By advancing steel reuse and the repurposing of white slag, the Spanish Demonstrator directly supports Drastic’s ambition to demonstrate how practical, industry-ready solutions can help scale circular practices across Europe.

Carolin Spirinckx, from Drastic’s coordinating partner, VITO, joined remotely to present the project’s work on linking ecosystems and business models. This approach is central to Drastic’s ambition to strengthen circular value chains in the built environment.
The event brought together a diverse group of practitioners, innovators, and community leaders, creating a constructive environment for exchanging ideas on advancing the circular transition. The discussions and experiences shared demonstrated how circular systems can thrive when knowledge is exchanged across sectors and regions.
For the Drastic team, the event highlighted the strong alignment between the project’s objectives and the many global initiatives pursuing similar ambitions. The project looks forward to continuing this shared journey toward circular and resilient futures.
From barn timber to biennial pavilion: pushing the boundaries of tagging and traceability in reclaimed materials
A member of the public scans QR codes from a pile of timber with their phone.
One of Drastic’s Norwegian partners, Omtre, recently had the opportunity to test its Demonstrator’s ‘smart tagging system’ at the Copenhagen Architecture Forum’s Copenhagen Architecture Biennial, via one of the event’s ‘slow pavilion’ structures.
The tagging system is a key element of Drastic’s Norwegian Demonstrator, which promotes the reuse of reclaimed timber from disassembled barns, and was used to help construct one of the event’s two slow pavilions, “Barn Again”, erected in the Copenhagen Cultural District of Denmark.
The pavilion was a contemporary re-imagination of the traditional Norwegian barn by Tom Svilans & THISS Studio, in collaboration with Bollinger+Grohmann and Winther A/S.
Using QR codes and labels, every unique timber element within the pavilion was linked to an online database carrying material information, timestamped images, and its exact position in the 3D model. This was crucial for managing sourcing, design, and production, since no two beams were alike.
This unique tagging system will be utilised by Omtre in their work on the Norwegian Drastic Demonstrator, which seeks to examine various uses of reclaimed timber (especially in temporary commercial structures) with a view to increasing circularity and reducing carbon emissions within the built environment via the use of reclaimed materials.
Explore the timber element database.
