Independent lifecycle assessment (LCA)[1] completed in August 2023.

over Cost and emissions savings 50-year asset life were based on a conservative improvement in corrosion resistance[2] .

Significant (46x) ROI is achieved given coatings costs are a small proportion of the overall cost of steel asset maintenance.

Analysis does not include any returns from potential productivity benefits or asset life extensions.

Sparc has designed ecosparc[®] to be a drop-in additive product which is incorporated by coatings companies at the point of manufacture in the same way as a pigment.

Sparc has established commercial manufacturing with capacity to produce enough additive to dose ~ . 4.5ML/annum of enhanced protective coatings[1]

Production units are small and modular and can be rolled out rapidly.

Sparc will seek to initially control the manufacturing process to ensure quality and IP protection; toll manufacturing via global partnerships will be considered for future volume expansions.

Sparc’s end customers are coatings manufacturers producing ecosparc[®] enhanced coatings for the oil & gas, mining, infrastructure and marine industries.
