Update on sustainability initiatives

SigmaRoc plc, the specialist quarried materials group, is pleased to provide an update on its latest sustainability initiatives, set out as part of the Group's ambition to reach net zero by 2040.

Cement-free carbon negative concrete blocks

The UK's leading supplier of concrete blocks, CCP Building Products, has partnered with Carbon8 to develop cement-free, carbon negative concrete blocks. These blocks will be produced using SigmaRoc's Greenbloc technology together with Carbon8's carbon negative aggregates.

The Greenbloc technology is based upon reducing the cement content in concrete, which contributes the highest amount of carbon. CCP has developed a process which uses ground granulated blast-furnace slag (GGBS) as the main raw ingredient. Carbon8's technology captures and stores more CO₂ in the aggregates than is released in the manufacturing process, resulting in a carbon negative block.

Collaboration with OX2 on development of e-fuel production

Nordkalk has recently entered into a collaboration with OX2, which focusses on the development of fossil free energy including e-fuel production opportunities in Gotland, Sweden. The e-fuel produced by the partnership would be earmarked for use in Nordkalk's co-located production facilities or for shipment to other industries.

New sustainable product ranges: Nordkalk Next and Nordkalk Complete

Nordkalk is pleased to announce it will launch two new suites of revolutionary products in its sustainable product range. The ranges will consist of:

-     Products made of a minimum of 33% circular materials and 100% circular materials.

-     CO₂ neutral products.

-     Products produced with a minimum of 33% fossil-free energy.

Nordkalk Complete and Nordkalk Next will be available from 2024 in Finland and Sweden, with further roll-out planned as production increases.

Aqualung

Following initial commissioning at Köping in Sweden, the Aqualung CO₂ capture module has started the second phase of its programme, consisting of the preparation of captured CO₂ for industrial use. A dedicated purification, compression and liquefaction unit was installed to transform captured CO₂ into an industrial gas capable of being using in industrial processes or sequestered in CCS facilities. Further updates will follow in the New Year.

Max Vermorken, CEO of SigmaRoc, commented:

"We are very pleased with the progress made on all ESG initiatives. We keep demonstrating we can lead the sector both in reducing our CO2 footprint, utilisation of materials, circular product development and general innovation."
