UAB Ecostone Solutions develops and manufactures low-clinker, CO₂-mineralised concrete and fibre-cement products for the construction sector.
Figures from the peer-reviewed baseline; product performance under industrial validation.
Conventional precast concrete depends on carbon-intensive Portland clinker. Our materials attack the problem from both ends, using a mineral that is abundant in the EU.
Opoka is a Lithuanian siliceous-calcitic sedimentary rock rich in reactive amorphous silica and calcite. Substituting part of the clinker cuts the largest source of embodied carbon and keeps the supply chain inside the EU.
Products are cured in a CO₂ atmosphere. Calcium-bearing phases react with the gas and bind it permanently as solid calcium carbonate — densifying the material while storing carbon for good, not temporarily.
Avoided clinker emissions and stored CO₂ are always reported separately — never double-counted.
From a flagship fibre-cement façade board to pressed precast, every line shares the same opoka-and-CO₂ chemistry.
Thin, non-combustible (A2) cladding boards reinforced with EU-sourced basalt fibre — a lower-carbon alternative to conventional Portland-cement fibre-cement.
Pressed precast units cured under CO₂, with measured carbon uptake and competitive strength — the validated baseline behind the technology.
Façade panels, linear and stair elements and bespoke decorative concrete — drawing on the company's precast manufacturing experience.
CarbonLock is our R&D programme taking opoka-based carbonation from the laboratory to repeatable pilot manufacturing.
Opoka, reduced-clinker binder and EU-sourced basalt fibre are proportioned to a controlled recipe.
The mix is pressed or cast into pavers, slabs and thin façade boards under controlled compaction.
Units cure in a CO₂ chamber; calcium phases mineralise the gas as stable calcite within the matrix.
Strength, durability and a third-party ISO 14040/44 life-cycle assessment confirm performance and carbon balance.
Reduced clinker plus mineralised CO₂, targeting a verified cradle-to-gate reduction against a conventional reference product.
CO₂ is chemically bound as calcium carbonate — locked into the stone, not released over time.
Lithuanian opoka and EU basalt fibre reduce dependence on imported supplementary materials.
A mineral matrix means A2-class fire behaviour for façades and inert, recyclable material at end of life.
Ecostone Solutions designs, develops and manufactures advanced mineral building materials. We work as a single accountable SME, buying specialist testing, characterisation and life-cycle analysis as external services.
