AshCycle pilots in CROATIA

Transforming ash into opportunity: advancing circular construction for a sustainable Europe

Wood biomass ash-based alkali-activated technology in Croatia

Pilot product: Sustainable urban AAM bench
Location: Beton Lučko facility, Croatia
Technology: Alkali-activated concrete
Ash type: Wood biomass mixed ash 
Ash replacement level: 15 wt.% of the total precursor


This is the first industrial-scale application of alkali-activated technology in Croatia, using wood biomass ash from the Žakanje power plant as a replacement for slag. The demonstration was carried out in collaboration with the Žakanje power plant, the precast concrete producer Beton Lučko d.o.o., and the University of Zagreb Faculty of Civil Engineering.
