We help YOU build with optimized climate-neutral materials.

ecoLocked Materials® are CO2-negative concrete admixes and additives

ecoLocked Materials consist of a range of carbonaceous admix and additives, optimized for improving the environmental and mechanical properties of concrete. By using them, you store captured carbon in concrete and make up for the embodied emissions from conventional ingredients like cement and sand.

As a result, you can reduce the concrete’s CO2-footprint without compromising on performance.

What do we offer?

Our turnkey solution provides all the tools required for you to achieve your sustainability goals.

“Drop-in” solution for smooth integration

ecoLocked Materials are performance-optimized, locally sourced, and customized for your needs. Whether you work with ready-mix concrete or precast elements, we provide you with a solution that can be easily integrated with your existing processes and infrastructure. Check out the product pages to learn more about formats and integration options.

Mix design & technical consulting

We offer expert consultation on material integration and concrete mix design optimization, ensuring optimal climate impact and mechanical performance. Our team works closely with you to tailor solutions that meet your specific project requirements, helping you achieve both sustainability and high-quality performance.

Carbon management services

We support you with Life Cycle Assessments (LCAs) and help you obtain audited Carbon Dioxide Removal (CDR) certificates and Environmental Product Declarations (EPDs). Whether you need guidance on insetting emissions, conducting thorough LCAs , or understanding regulatory requirements, our team is here to assist you every step of the way.

Technology

Consistent quality & reduced dependency on raw materials

Our technology is suitable for most concrete applications. Each biochar, sourced from different biomass residues, possesses unique chemical and mechanical characteristics. At ecoLocked, we carefully select the most suitable biochar for a specific concrete application. This we then refine and process to develop the optimal biochar-based admixes and additives. Next to our own concrete lab and proprietary processing methodology, we have developed our data-driven product development platform to speed up the process. ecoLocked Platform features a proprietary database and a mix-design calculator that connects building material performance with various biochars and other decarbonization technologies.  

We evaluate your needs and deliver an optimized concrete mix design with ecoLocked Materials.

Atmospheric Carbon Storage

Increased capacity to store atmospheric carbon, during initial curing and over the concrete’s lifetime

Weight reduction

Creating lightweight concrete while maintaining strength

Improved durability

Lower maintenance and longer building lifetimes thanks to resilience to, e.g., frost

Increased thermal insulation

Reduced need for other materials for thermal and noise insulation

Accelerated or delayed curing

Speed up the curing for precast concrete, slow it down for ready-mix concrete

Pigmentation

A natural darker hue to the concrete without additional pigments

Pavers

Our first commercial product. We have successfully produced carbon-neutral paving stones at multiple customer plants with a performance that meets the industry standard.

Precast elements

ecoLocked Materials® can be used to produce various precast elements right at the factory. We have already created multiple custom mix designs for our customers’ end applications.

Ready-mixed Concrete

Our product for RMC can be mixed on-site without any changes in the process. We already support any non-structural RMC applications.
