Turn waste biomass into a concrete business
Partner with ecoLocked to unlock the construction sector as a carbon sink and develop a biochar business case.

Why biochar in concrete?
Concrete provides a durable carbon sink - far beyond a single building’s lifetime. With >20 billion m3 poured annually, this means carbon storage at scale.
At the same time, concrete is the largest untapped market for biochar. Each m3 can absorb 25–80 kg biochar – representing a potential of at least 500 Mt per year, or €400–600 billion in revenue potential.
Conversely, biochar provides a decarbonization path for the concrete sector. Carbon-negative biochar admixes replace conventional materials like cement & aggregates, providing a measurable reduction of concrete’s net CO2 footprint by up to 100%.

Buildings are the biggest carbon sinks we’re not using yet!










Building the bridge between biochar and concrete
Biochar production is the foundation. But the true value emerges when biochar is transformed into certified, high-value products that preserve the carbon. That’s where ecoLocked comes in – unlocking concrete as a permanent carbon sink and scalable business case, with predictable revenues from materials and CO2 credits.

Our core tool: The ecoLocked Platform
To deliver on these promises, we have built a comprehensive Biochar-to-Concrete Enablement Platform, powered by 4+ years of R&D and 800+ tested mixes.

Material qualification
Our performance benchmarking database, which includes data on ~150 biochar types, allows for rapid assessment of biomass and biochar suitability across various concrete types, enabling a quick evaluation of performance potential.
Product specs definition
Supported by our Mix Optimization Tool, which predicts concrete performance of biochar-based mixes, we define required product specs (particle size, moisture, format, dosage). This is the basis for processing operations - and for obtaining the necessary certifications to access the concrete market.
Processing Hub design
Our proprietary ecoLocked Processing Hub is designed for low-cost conversion of raw biochars into drop-in-ready concrete admix materials - scalable, safe, and with a setup designed to comply with European concrete norms under System 2+ certification and ICROA-endorsed carbon standards. Its modular design allows easy adaptation to diverse concrete markets and applications.
How we work together
Each project is unique. Whether you already have a biochar production set up, are just considering turning your waste biomass streams into biochar, or have concrete production operations and looking to integrate biochar: From opportunity alignment to market launch, we support you every step of the way.
