Circular Design and low Carbon Footprint

Areas of Potential Use

IMG_9868.jpg

ZeroC* Precast Concrete

A mix design for a 100% circular ZeroC precast concrete is under development, utilizing our low carbon aggregates and a binder developed by our partner Gerosion in the AlSiment, “umhverfisvænn arftaki sements” project.

These circular precast units will have the lowest carbon footprint of any concrete on the market today.
