ecoLocked GmbH

ecoLocked is turning buildings into carbon sinks - and helps you do so, too. We have built an end-to-end solution to convert captured carbon from local biomass residues (biochar) into functional, carbon-negative concrete admixes. These admixes substitute cement or aggregates and permanently store CO2 in buildings, creating certified negative emissions which can either be used by the construction industry to address residual emissions or sold as premium-quality carbon credits. Whether you already produce biochar, manage biowaste, or make concrete - we have everything you need to set up your own Carbon-to-Concrete Platform — proven, scalable, and efficient. Using our databases containing over 800 concrete tests across more than 100 biochars, we quickly assess feedstock suitability, while our Mix Optimization Tool helps us define the right product specs for target concrete applications. Our modular Processing Hub design, certified for concrete and carbon markets, enables low-cost conversion of biochar into drop-in concrete admixtures that meet European norms. All supported by digital quality management, material flow tracking and MRV.
