This alliance, a first of its kind in the UK, is set to revolutionise the production and sale of sustainable limestone aggregates. The agreement has the potential to generate over £150 million in incremental revenue while significantly reducing SigmaRoc's environmental impact through the innovative repurposing of limestone quarry waste.

As part of this groundbreaking agreement, Duo Group will play a pivotal role in establishing state-of-the-art processing plants at up to seven SigmaRoc limestone quarries. Their expertise and commitment will be instrumental in reprocessing historically uneconomical quarry tip waste into a premium construction material, thereby advancing SigmaRoc's ambition of utilising 100% of the resources it quarries.

Quarry tips, also known as spoil tips, are accumulations of previously uneconomical processable material removed by the quarrying operations. By repurposing this previously overlooked resource, using state-of-the-art processing equipment installed by Duo Group, the Strategic Alliance aims to extend the operational life of quarries, conserve natural resources, and align with sustainable development goals. This initiative also supports SigmaRoc's ambition of utilising 100% of the resources it quarries, ensuring a more sustainable future for the construction and infrastructure sectors.

Under the agreement, finalised during the Hillhead 2024 exhibition in Buxton, Derbyshire, England (25-27 June), Duo Group will establish large-scale, state-of-the-art reprocessing plants to cover material preparation and processing, load and haul, plant operation, and material dispatch. SigmaRoc will put at the disposal of the Strategic Alliance all unprocessed "tipped" materials which previously held no commercial value.

Martin McWilliams, Group Managing Director of Duo Group, commented: "We are delighted to enter into this agreement with SigmaRoc. SigmaRoc has become a major player in recent years in the UK and Northern Europe. They have a clear roadmap on their growth journey and their ambition to reach 100% utilisation of all production materials. We are excited to be part of this journey. We share equal values in sustainability and innovation, and together, we can achieve significant milestones together by reducing the environmental footprint of the aggregates industry and helping to meet the sector's ESG targets."
