The basis of our climate technology is the developed aggregate Clim@Add®. It consists of up to 96% technical carbon. This is produced during the thermochemical conversion of forest residues from sustainable forestry. The special process converts the CO2 bound in the residual materials into technical carbon. This provides the basis for our Clim@Add® aggregate. 1 kg of Clim@Add® binds up to 3 kg of CO2 that plants have absorbed from the atmosphere during their lifetime. The carbon used is EBC certified, chemically stable and can be reintegrated into material cycles. 

The permanent incorporation of our technical carbon into concrete and asphalt improves the functionality of the building materials and creates a permanent carbon sink. At the same time, the use of Clim@Add® can substitute primary raw materials such as cement, thus saving further emissions. In sum, this results in the building materials becoming not only climate-neutral, but climate-positive.

CO2 removal through negative emission technologies 

The so-called PyCCS, pyrolytic or pyrogenic carbon capture and storage, is one of the most promising negative emission technologies (NET). It can already be applied today, it has no long research lead time, low investment costs, and can be integrated into existing systems as a plant upgrade.
A key advantage is also that no additional energy is required - on the contrary, the process generates sustainable, regional energy in the form of electricity and/or heat in addition to the CO2-absorbing carbon, which can be fed into the cycle.

Addressing climate change with plant carbon-based carbon sinks.

When technical carbon is incorporated into concrete and asphalt, the carbon forms a bond with the product matrix, thus the sinks remain permanent and can even last beyond the life of the products.
Our technology is also compatible with existing sustainability measures such as recycling solutions.

Act locally - protect the climate globally 

In addition, local procurement and short transport routes also play a role in the sustainability balance of the innovative building material. The technical carbon is based on a regionally produced basic raw material. The wood used comes from certified, sustainably managed forests. We thus ensure sustainable supply chains and optimal use of biogenic residual material flows. At the same time, we contribute to the circular economy. In accordance with the Closed Substance Cycle Waste Management Act, our solution represents a higher-value utilization stage compared to incineration.
For functionalization, our additive is added and projects are realized with local building material manufacturers. We cooperate with regional residual material recyclers and disposal companies, energy suppliers and pyrolysis plant operators and close local recycling loops.

Sustainability at the core business

We develop solutions and products together with our customers. In addition to concrete and asphalt applications, we also implement customized solutions. Ongoing research projects enable us to further optimize input streams and placement methods. 

With our solutions, product ranges can be expanded to include innovative sustainable products, and new sources of income can be tapped through energy feed-ins and CO2 certificates. The certificates generated are issued to our customers. In this way, for example, unavoidable residual emissions in the production process can be offset. Emissions offsetting within our own value chain can be used as a central element for sustainability reporting and communication to employees, customers and investors.

We offer our customers emission reduction at the core of their business and a strong solution to respond to increasing political and social pressure.

So that you are ahead of the competition when it comes to climate protection!
