Eco-Locked

ecoLocked develops CO₂-negative materials for the construction sector, converting captured carbon into functional concrete admix products marketed as ecoLocked Materials. Its Carbon-to-Concrete Platform, centered on a Processing Hub, links biomass residues, pyrolysis-derived biochar, material processing, certification and concrete production so that carbon contained in biomass is stored in building structures rather than released as CO₂. The company frames concrete—described as responsible for around 8% of global emissions and projected to double in production by 2060—as a vehicle for permanent carbon storage, positioning buildings as carbon sinks.

The platform is presented as integrating into existing construction and concrete-production workflows. Product offerings include eLM Zero for concrete manufacturers seeking CO₂-reduced and carbon-storing concrete, platform access for biochar producers and corporates holding biomass residues who want to enter the low-carbon construction market, and permanent carbon removal certificates for carbon credit buyers, which the company describes as measurable, traceable and third-party-verified. The company states a target of 1 billion tonnes of CO₂ impact by 2040.

Business model

ecoLocked supplies biochar-based concrete admix materials (ecoLocked Materials, including eLM Zero) and provides platform services that allow biochar producers and holders of biomass residues to convert feedstock into concrete-focused products. It also offers permanent carbon removal certificates to buyers seeking to offset hard-to-abate emissions.

Traction

Reference projects include prefabricated concrete walls for MARKGRAF's training and educational center in Kemnath, Bavaria (November 2025), with concrete CO₂ cut by more than 60%; a carbon-neutral foundation slab for a construction facility in Tauernfeld delivered with Max Bögl (October 2025); and a city name sculpture in Potsdam made with CO₂-neutral concrete (June 2025).
