A building material that binds CO₂ instead of emitting it.
Építőanyag, amely megköti a CO₂-t, ahelyett hogy kibocsátaná.
Pille Brick is a cement-free building material concept made from industrial by-products. It is designed to bind CO₂ while it cures and to use waste heat in production, for prefabricated wall, floor and panel elements.
Research and development stage · UK patent application filed by the founder · technical details under NDA
Construction needs walls with a smaller carbon footprint.
Az építőiparnak kisebb szénlábnyomú falak kellenek.
Pille Brick addresses three problems at once: cement-heavy binders, energy-intensive production, and industrial by-products that end up in landfill.
Cement is carbon-intensive
A cement nagy szén-dioxid-terheléssel jár
Cement production is one of the largest industrial sources of CO₂, commonly estimated at around 7–8% of global emissions.
By-products go to waste
A melléktermékek kárba vesznek
Metallurgy and thermal processes leave mineral by-products that are often stockpiled or landfilled instead of being used.
Production heat is expensive
A gyártáshoz szükséges hő drága
Fired and cement-based masonry needs a lot of energy, while industrial sites release usable waste heat.
From industrial by-product to building element
Az ipari melléktermékből építőelem
The technology is described in the founder's UK patent application “Pille Brick — Sustainable CO₂-Integrated Building Material”. The four principles below are the publicly shareable outline; they are design goals, not measured results.
Simplified outline of the patent application; compositions and parameters only under NDA.
Industrial by-products
Ipari melléktermékek
The raw material comes from by-products of metallurgy and thermal processing, reducing the need for newly quarried material.
Cement-free binding
Cement nélküli kötés
An alternative binding process replaces Portland cement, the main carbon source of conventional concrete and blocks.
CO₂ bound in the material
CO₂ az anyagban megkötve
CO₂ is designed to be taken up during production and to become part of the hardened material.
Waste-heat production
Hulladékhővel gyártva
Production is designed to use industrial waste heat instead of dedicated firing, lowering the energy demand.
Design goals
Tervezési célok
Thermal insulation
Hőszigetelés
Insulation built into the wall material itself.
Design goalLoad-bearing strength
Teherbírás
Strength suitable for walls, floors and panels.
Design goalLower embodied carbon
Kisebb beépített szénlábnyom
No cement clinker; CO₂ bound during production.
Design goalWorks with standard trades
Megszokott szakmunkával
Takes conventional plasters; channels can be cut for wiring and pipes.
Design goalNo independently validated test data has been published yet. Compositions, mix ratios, process parameters, test data and patent claims are not published on this website; they are discussed only under a signed NDA.
Intended applications
Tervezett alkalmazások
Pille Brick is aimed at prefabrication: elements made in a plant and assembled quickly on site.
Prefabricated elements
Előregyártott elemek
Wall, floor and panel elements.
Modular systems
Moduláris rendszerek
Lightweight modular construction.
Residential buildings
Lakóépületek
Family houses and apartment buildings.
Industrial & commercial
Ipari és kereskedelmi
Halls, offices and multi-storey frames.
