About SigmaRoc plc:

SigmaRoc is a quoted lime and limestone group, targeting quarried materials assets in the UK and Northern Europe.

Lime and limestone are key resources in the transition to a more sustainable economy. New applications for lime and limestone products as part of a drive for sustainability include the production and recycling of lithium batteries, the decarbonisation of construction including through substitution of cementitious material and new building materials, and environmental applications including lake liming, air pollution and direct air capture.

SigmaRoc seeks to create value by purchasing assets in fragmented materials markets and extracting efficiencies through active management and by forming the assets into larger groups. It seeks to de- risk its investments through the selection of projects with strong asset backing.
