Ireland: Researchers at Trinity College Dublin's School of Engineering have developed a novel, 51%-reduced CO₂ concrete using biomass ash from the Edenderry power station. Precast concrete products company FLI Precast Solutions also collaborated on the research, which piloted two possible methods. The first method partially replaces cement with biomass ash, while the second eliminates cement entirely through geo-polymerisation of ash with slag. Enterprise Ireland funded the project under its Construct Innovate initiative. The partners will now seek to advance the adoption of this technology across Ireland.
The Edenderry power station supplies 150,000 homes with energy produced using 100% biomass from wood and agricultural sources.
Researcher Sara Pavia said "Biomass is inherently carbon-neutral. However, the disposal of the resulting ash byproduct represents a considerable challenge.”
