World record! 300 m³ biochar concrete installed in 14h!
On 21.08.2023, an astonishing 300 m³ of Biochar Concrete were installed in just one day. For the first time, it was possible to pump the Biochar Concrete.
The speed and efficiency of this process was impressive and clearly demonstrated the enormous progress that the construction industry can achieve through the use of sustainable materials and innovative technologies. The path of the construction industry into a new era of environmentally conscious and efficient building has been shown with OPENLY Valley Widnau.
For this project, together with Sigmund Sieber AG & Carstorcon resp. the Zindel Group, a proprietary biochar concrete was developed over a period of 1 year, which passed all approvals and tests.
1 kg of biochar binds 3 kg of atmospheric CO₂. Click here for the CO2 balance
When added to concrete and used as an aggregate, it can provide a CO2-reduced building material that puts all conventional types of concrete in the shade. By way of comparison, Neustark stores approx. 5 kg of CO2 per m3 - biochar stores up to 40 times as much.
The biochar brings many advantages in addition to CO2 storage (known in technical terms as CCS - carbon capturing & storage). For example, compressive strength is increased as the activated carbon particles interlock in the cement matrix.
For this building material, we have followed the principle of preventing emissions in the first place and then compensating for them. Our plant charcoal concrete requires slightly less cement than conventional concrete. This progress is a sign of the tireless work and commitment of the OPENLY team and its partners and professionals involved in the development of the OPENLY-bionic building material system.
With manageable effort, it is now possible to retrofit a local ready-mix concrete plant near your construction project. OPENLY now has the expertise and suppliers for your construction project. Contact us
Another innovation is the CO₂-neutral steel from our partner Stahl Gerlafingen or Locher Bewehrungen (SFS Group).
The first construction site in Switzerland to use 100% recycled iron and CO₂ neutralized reinforcing steel. A significant milestone for the construction industry!
This innovative approach not only helps to conserve the earth's resources, but also drastically reduces the impact on the environment. The use of recycled materials significantly reduces the need for virgin iron and steel, which in turn minimizes carbon emissions during manufacturing. This pioneering construction project sends a positive signal to the entire construction industry and encourages others to adopt similar environmentally friendly approaches.
Without our partners, who pursue these approaches together with us, this progress would not have been possible in a short time.
