Start of C-Factory Project

Start of the C-Factory project – a major milestone for climate-friendly construction!

C-Factory is designed to become the worldwide first carbon concrete plant for CO2-storing prefab components, backed by around EUR 14 million in funding from Germany’s Federal Ministry for Economic Affairs and Energy and running through the end of 2029.

The project builds on two decades of research and practical testing, including the Carbon Concrete CUBE at Technische Universität Dresden, the worldwide first building made of carbon concrete.

A long-standing collaboration

As aerogel-it, we are especially proud of our long-standing collaboration with Kahnt & Tietze GmbH who are spearheading this effort (in the photo below with Saxonian State Minister Dirk Panter). For many years, we have worked together with them to minimize wall thickness through the combination of space-saving carbon concrete and aerogel high-performance thermal insulation e.g. SLENTITE and silica aerogel blankets in the Carbon Concrete CUBE, and in several public funded projects such as BIOVIPWALL. This powerful combination helps create slimmer, lighter and more durable building envelopes with lower material use, lower transport and installation effort, and improved lifecycle performance.

What it means for sustainable construction

What makes C-Factory so exciting is its potential to take sustainable construction another decisive step forward:

1️⃣ Carbon concrete already enables significant savings in cement, sand and gravel because carbon reinforcement does not corrode and allows much slimmer components.
2️⃣ In combination with CO2-mineralized aggregates and additional CO2-storing materials, future components are intended to become carbon stores themselves.
3️⃣ Paired with aerogel high-performance insulation, this approach unlocks even greater potential to drastically reduce wall thickness while maximizing usable space and energy efficiency.

Congratulations to Alexander Kahnt, Matthias Tietze and the entire team, as well as the partners from TU Dresden, HTWK Leipzig and the wider C3 ecosystem, on bringing a technology from research and pilot projects into industrial reality!

We are excited to see the impact C-Factory will have on resource efficiency, climate protection and the future of construction!
