Circular economy
in construction
— Rethought.
ZIRKULAR-X is developing an AI-powered platform that automatically analyses existing buildings, assesses materials, and visualises reuse potential.

Millions of existing buildings contain valuable materials that are lost during demolition — because nobody knows exactly what has been used in their construction. Plans are in paper form, data is fragmented, and documentation is incomplete.
ZIRKULAR-X closes this gap: Artificial intelligence unlocks analogue inventory records, semantic knowledge graphs link all data, and an automated circularity index shows which materials can be reused or recycled.
The result is a scientifically sound, economically viable basis for resource-saving decommissioning and refurbishment strategies.
Collaborative research
Seven partners from industry, applied research, and science are pooling complementary competencies over the entire project duration.
