What ecoLocked does

ecoLocked GmbH is a Berlin-based climate-tech company founded in September 2021 that develops CO2-negative building materials by converting biochar (stable carbon from biomass pyrolysis) into functional concrete admix materials. The company's core technology is the Carbon-to-Concrete Platform, which integrates a Processing Hub (modular hardware for milling, blending, and packaging of raw biochar into construction-ready products, scalable from 500 to 3,000+ tonnes per year) with a patent-pending Concrete Integration System that runs biochar mix optimization and performance prediction against a database of 800+ tested concrete mixes covering Ready-Mix, Pre-Cast, Earth Moist, and Lightweight applications, and a benchmarking library of 100+ biochar types. The first commercial product, eLM Zero, is certified under EN 12878 (AVCP System 2+) and carries an EN 15804-compliant EPD with a verified GWP-total of -2.96 kg CO2e per kg, enabling up to 100% CO2 footprint reduction in concrete. A second variant, eLM Light, targets lightweight and thermally insulating applications. The Processing Hub is EBC-certified and ATEX-compliant, and carbon storage is third-party-verified under the CSI Global C-Sink standard (ICROA-endorsed) through MRV partners Carbonfuture and Cula Technologies.

ecoLocked monetizes through three primary streams: (1) one-time sales of ecoLocked Materials (eLM Zero and eLM Light) as powder, granulate, or slurry to concrete manufacturers on quote-based, project-specific pricing; (2) licensing of the Carbon-to-Concrete Platform to biochar producers and corporates holding biomass residues, enabling partners to deploy their own Processing Hubs with >20% cost reduction; and (3) issuance of MRV-verified carbon removal certificates for both insetting and voluntary carbon markets. The go-to-market is enterprise field sales with technical sales support, operating across four customer segments: concrete manufacturers (precast, ready-mix, paver producers such as MARKGRAF, Max Bögl, Nüdling Betonelemente, Geert Morssinkhof), biochar producers and corporates with biomass residues, real estate and construction developers (gewobau Rüsselsheim, BNB), and carbon credit buyers. Current commercial geography is DACH, Netherlands, and the Nordics, with a first UK reference project (The Portals, Ipswich) in October 2025. The company has raised approximately €5.8 million in venture funding across two seed rounds (€1.8M in 2022 led by Counteract; €4M in 2024 co-led by Matterwaves Ventures and Climentum Capital), supplemented by more than €1M in public funding, and employs between 11 and 50 staff across its Berlin headquarters, Bernau production facility, and project operations.

Core offering

ecoLocked develops and sells certified CO2-negative concrete admixture materials (eLM Zero and eLM Light) made from biochar, alongside its Carbon-to-Concrete Platform that converts biomass residues into permanent carbon-storing concrete inputs. The company also issues MRV-verified carbon removal certificates and licenses its Processing Hub and Concrete Integration System technology to biochar producers and concrete manufacturers.

Product overview

ecoLocked operates a Carbon-to-Concrete Platform centered around a Processing Hub that converts biomass residues (biochar) into certified CO₂-negative concrete admix materials. The core product line includes eLM Zero (carbon-negative concrete admixture available as powder, granulate, or slurry) and eLM Light (lightweight concrete variant). The platform integrates the Concrete Integration System and Processing Hub Technology modules, enabling partners to license and deploy biochar-to-concrete operations. The Mix Optimization & Prediction Tool supports mix design customization. Carbon Credit Certificates provide MRV-verified carbon removal for sustainability reporting.

Scale indicators12 records

Recent moves8 records

Expansion highlights7 records

Direct peers

• CarbonCure Technologies: CarbonCure injects captured CO2 into ready-mix concrete to permanently mineralize it, selling retrofit equipment to concrete producers. It is the closest direct competitor to ecoLocked in the carbon-negative concrete admixture space, addressing the same concrete-manufacturer customer base with a complementary technology pathway.

Emerging players

• Carbicrete: Carbicrete produces cement-free concrete using steel slag and captured CO2 curing, eliminating Portland cement entirely. It targets precast concrete manufacturers with a carbon-negative product, overlapping with ecoLocked's precast and paver use cases via a different decarbonization lever.
• Solidia Technologies: Solidia Technologies uses a CO2-cured concrete binder system that sequesters carbon during curing. Like ecoLocked, it targets concrete manufacturers seeking to lower embodied carbon and produce carbon-negative products, with comparable enterprise sales motions.
• Brimstone: Brimstone produces carbon-negative Portland cement from calcium silicate using industrial waste streams. It competes for the same low-carbon concrete buyer segment but addresses embodied carbon via cement substitution rather than admixture dosing.
• CarbonOrO: CarbonOrO develops CO2-mineralized aggregates for concrete production, offering another pathway to lower-carbon concrete. It is an emerging competitor in the carbon-negative concrete materials space with overlapping concrete-manufacturer customers.

Broad incumbents

• Holcim: Holcim is one of the world's largest cement and concrete producers, with a portfolio of low-carbon and carbon-neutral concrete products (e.g., ECOPact). It is a broad incumbent that competes for the same sustainability-mandated concrete buyers and could acquire or replicate ecoLocked's approach.
• Heidelberg Materials: Heidelberg Materials is a global cement major that has launched its own carbon-neutral and CCUS-backed concrete products (evoZero). As a DACH-headquartered incumbent, it directly overlaps ecoLocked's geographic core and competes for the same EU-regulated low-carbon demand.
• Cemex: Cemex offers Vertua, a lower-carbon concrete product line, and has invested in carbon capture and mineralization technology. It is a broad incumbent in the low-carbon concrete category with global reach that ecoLocked currently lacks.

Others

• Carbonfuture: Carbonfuture is a digital MRV platform and registry for durable carbon removal certificates, and is an ecoLocked partner. It is thematically adjacent as the carbon-credit infrastructure layer through which ecoLocked monetizes removals, and a comparable enablement peer for biochar-based removal projects.
• Puro.earth: Puro.earth is a carbon removal marketplace that issues and trades certified biochar-based removal credits. It is an adjacent enabling platform for the same voluntary carbon market ecoLocked targets, providing a benchmark for credit pricing and demand dynamics.
