Our solution for
concrete manufacturers

This depends on your performance requirements and the specific concrete application. In structural applications where CE marking is required under EN 12878, up to 8 percent of the cement mass can be added to the mix design. In other applications, such as paving stones or concrete furniture, eLM Zero is typically added at around 1 to 5 percent of the total concrete mass. These dosages can be efficiently integrated into existing mix designs using our proprietary mix optimization and performance prediction technology. The result is a high-performing, consistent concrete that stores carbon, meets regulatory and application requirements, and delivers targeted performance improvements aligned with your expectations.

eLM Zero is designed to maintain strength while improving other concrete properties like durability, insulation and setting time, depending on formulation. They partially substitute cement or aggregates.

We tailor the mix design (dosage, type of product) with the concrete producers to the specific application — precast, ready-mix, screed, non-structural or structural. We run application-specific lab tests with your concrete producer to ensure performance and compliance.

Yes, eLM Zero-enhanced concrete is completely safe for humans and the environment.

From an environmental perspective, we exclusively utilize EBC-certified raw materials, derived from biomass residues that adhere to the REACH regulations, with limited chemical thresholds. Furthermore, our final products undergo elution testing to ensure that the user is not exposed to any hazardous materials.

From a health and safety point of view, we ensure that our products come with the necessary industry certifications and are compliant with industry standards. Research indicates that rather than leaching pollutants into the environment, biochar’s filtering properties lead to pollutant absorption thus reducing contaminants in the environments where they are used.

It depends — on the application, dosage, performance targets and which ecoLocked product is used.
Typically, costs are balanced by the carbon benefits (Scope 3 reductions, insetting) and by reducing high-impact materials like cement.
We’re always happy to provide a project-specific cost calculation once the application and mix design are defined.

Yes. The production of eLM Zero is factory-controlled and the product complies with the requirements for use in concrete applications according to EN 12878. It is CE-certified under AVCP System 2+ and follows the Carbonfuture CSI methodology for carbon storage validation. Our Processing Hub is also EBC certified, which is the highest standard for processing and handling biochar.
We operate within the standard concrete production process — no retrofitting, no special equipment required. Current projects across DACH & NL demonstrate full practical approval in real applications.

Yes, ecoLocked is in the process of issuing a full third-party verified EPD, aligned with EN 15804 and including the biogenic carbon storage effect.
Project-specific EPD scenarios can be prepared together with the concrete producer.
We also supply all relevant LCA data for early planning phases.

In practice, our products work very well in all standard exposure classes, especially when used in the approved dosage.
For applications with high chemical requirements, we recommend project-specific tests, as with any innovative additive. We support the mix development and check compliance with standards together with the concrete plant. As a general rule, most applications have already been successfully tested.
