Sustainable Construction Products

O.C.O Manufactured Limestone (M-LS) is a lightweight, sustainable carbon – neutral aggregate for modern construction created using our patented Accelerated Carbonation Technology (ACT) process.

ACT uses CO₂ to capture carbon from the processing of thermal residues into manufactured limestone for use within modern construction.

M-LS is durable and easily compactable and can be supplied as BlockMix for masonry and concrete projects or 6F for use in earthworks, pavements and bound materials.

M-LS is carbon neutral*. CO₂ is permanently sequestered as stable carbonate minerals.

0 Tonnes

0 Trees

Every thousand tonnes of M-LS produced captures the same amount of carbon dioxide as planting 4,000 trees every year

For every tonne of M-LS used, 1.4 tonnes of natural aggregate is saved; natural material can never be replaced

M-LS is tailored to the application required. Strength, density, and grading can be adjusted to requirement.

O.C.O Technology continues to develop new sustainable products. The technology can be applied to a multitude of applications, including the production of bricks, blocks, tiles and slabs, made from waste materials, and conventional cementitious materials.

*The carbon storage associated with the M-LS product is managed in Puro Registry for carbon removal credits and is only available by separate negotiation with O.C.O
