Mannok partners with Boliden and South Eastern Applied Materials to develop shale-based cements

08 October 2024

Ireland: Mannok, Sweden-based minerals company Boliden and the South Eastern Applied Materials (SEAM) research centre at South East Technological University in Carlow, Wexford and Wicklow in Ireland have launched a 30-month project to reduce the embodied CO2 emissions of cement. The project will investigate possible uses of shale as a supplementary cementitious material (SCM) in cement production and the CO2 curing of cement paste-based mine backfill. Enterprise Ireland has supplied funding worth €700,000 for the collaboration.

Mannok operations director Kevin Lunney said "We are delighted to be working with SEAM and Boliden on this critical research for the cement sector, which could have many far-reaching benefits for the construction sector more generally. Finding local, viable, low-carbon solutions for the industry can make a major contribution to lowering emissions in Ireland."

Boliden specialist development engineer Adam McElroy and section-mill process head Colum Burns said "This project will greatly enhance our knowledge and understanding of the potential for developing low carbon cement for mine backfill purposes and for utilising backfill systems as a carbon sink. The project will also investigate synergies between the cement manufacturing and mining industries that could enhance the sustainability of both industries."
