About - C-Twelve

OUR MISSION and VISION

Paving the way to a carbon-negative future.

C-Twelve was founded on a simple idea: that road construction materials can perform better while having a lower environmental impact.

Our vision is to help reshape the future of road infrastructure through innovative materials that improve durability, reduce maintenance requirements and support meaningful sustainability outcomes. By transforming waste into a valuable construction resource, we are helping build stronger roads, lower lifecycle costs and create a more sustainable future for generations to come.

C-Twelve is an Australian materials technology company developing innovative road surfacing and soil stabilisation solutions for the infrastructure sector.

By incorporating engineered carbon derived from waste materials into cold mix asphalt and stabilisation technologies, we create high-performance products that improve road durability while supporting more sustainable construction practices. Our solutions are designed to help asset owners, contractors and councils build stronger, longer-lasting roads with reduced environmental impact.

At C-Twelve, we believe the future of infrastructure lies in materials that deliver both performance and sustainability.

C-12 Plus is an advanced soil stabilisation solution designed to improve the strength, performance and longevity of road infrastructure.

By combining engineered carbon with proprietary emulsion technology, C-12 Plus enhances the performance of in situ materials, reducing the need for imported resources and extensive reconstruction. The result is a more efficient, cost-effective and sustainable approach to road construction, rehabilitation and maintenance.

C-12 Plus helps extend pavement life, improve asset performance and reduce the environmental footprint of infrastructure projects.

Technology

At the core of C-Twelve’s innovation is engineered carbon — a sustainable material created from waste biomass and other organic waste streams that would otherwise be burned or sent to landfill.

Through a controlled manufacturing process, this material is transformed into a stable carbon product that can be incorporated into road construction materials. When used within road infrastructure, the carbon remains stored within the pavement structure while enhancing the performance of the finished product.

By combining engineered carbon with proprietary binder technologies, C-Twelve has developed a new generation of road construction materials that deliver improved performance, reduced waste and more sustainable infrastructure outcomes.
