Advanced Circular Economy Corrosion Inhibitors: From Waste to High-Performance, Low-Carbon Solutions

Sustainability in materials development often involves trade-offs with performance or cost. This study presents a novel smart-release corrosion inhibitor that overcomes these challenges by integrating circular economy principles without compromising efficacy.

Using Life Cycle Assessment (LCA), the inhibitor’s cradle-to-gate CO₂ footprint—including raw material extraction, synthesis, and formulation—was quantified. Results showed a significant reduction compared to conventional inhibitors made from strip-mined inorganic materials.

The system is built on a recycled resin matrix sourced from industrial-scale waste streams typically destined for landfill or incineration. Through proprietary functionalisation, this material is transformed into a durable, long-life corrosion inhibitor (service life >25 years). The active component can be derived from renewable, bio-based feedstocks, enabling a fully circular system: a bio-based inhibitor embedded in a recycled carrier.

Electrochemical testing (Scanning Kelvin Probe) and standardized salt spray exposure (ASTM B117) in solvent-borne alkyd and epoxy systems showed performance on par with, or superior to, traditional inhibitors. Field deployments confirmed these findings in real-world environments.

This technology delivers up to 80% lower cost and CO₂ emissions compared to conventional systems—demonstrating that high-performance corrosion protection and sustainability can go hand-in-hand.
