Carbon negative solution

By leveraging its expertise in pyrolysis and chemical engineering, C-Twelve is able to produce biochar from a wide range of waste materials that would otherwise be discarded, reducing the amount of waste and environmental pollution.

The company’s innovative approach to road construction offers numerous benefits, including improved durability and reduced costs, making it an attractive option for local authorities, infrastructure companies, and construction firms alike. With a commitment to sustainability and innovation, C-Twelve is poised to revolutionize the road construction industry with its cutting-edge technology and sustainable solutions.

This is due to the high surface area and pore volume of biochar, which allows it to effectively bind with the asphalt binder and aggregate.

The use of biochar in Cold Mix Road Surfacing (CMRS) products has several advantages. Firstly, it has been found to improve the mechanical properties of the CMRS mixture, including increased strength, stiffness, and resistance to moisture damage.

Secondly, the incorporation of biochar into CMRS can also reduce the amount of asphalt binder required, which reduces costs and the environmental impact associated with the production of asphalt binder.

The production of biochar from waste materials, such as municipal waste, light industrial waste, and agricultural and forestry residues, can also provide an additional benefit by reducing waste and improving resource efficiency. This is because these waste materials would otherwise be burned or discarded through landfill or other processes, releasing greenhouse gases and contributing to environmental pollution.

Several studies have investigated the use of biochar in CMRS, and have found that it is a viable option for road construction. For example, one study1 found that the addition of biochar to CMRS improved the mechanical properties of the mixture and reduced the amount of asphalt binder required by up to 25%. Another study2 found that biochar can also improve the fatigue resistance of CMRS, which is an important property for road durability.

Cold mix that is carbon negative, lab tested, & proven to create hard-wearing roads

This green solution is designed to meet the highest standards of quality, durability and performance. C-12 Black has been tested and proven to withstanding extreme weather conditions and the harshness of the Australian environment.

C-12 Black’s unique blend of cold mix, biochar, and emulsion solution creates a uniquely strong solution that has superior resistance to wear and tear compared to traditional hot mix asphalts.

C-12 Black is carbon negative, meaning it removed more carbon from the environment than the process of creating and applying it, its unique formula hugely reduces the environmental impact of road construction, making it an ideal choice for all applications as we work towards carbon net zero targets.

F.A.Q.

What is biochar?

Biochar is a carbon-rich material produced through pyrolysis, a process that converts biomass into a solid residue by heating it in the absence of oxygen.

How is biochar used in cold mix for road surfacing?

Biochar is integrated into the asphalt mixture, improving road stability, strength, and water drainage, while reducing rutting and cracking.

What are the benefits of using biochar cold mix?

Using biochar enhances road durability, reduces maintenance needs, improves skid resistance, and contributes to sustainable practices and carbon sequestration.

How does biochar make road construction sustainable?

Biochar reduces the carbon footprint of road construction by acting as a substitute for traditional aggregates and offers long-term carbon sequestration potential within the road infrastructure.

Why choose biochar in c-12 BLACK?

Utilizing biochar promotes environmentally friendly road construction, increases road lifespan, and reduces costs through improved performance and sustainability.
