The study used a cradle-to-grave methodology to assess impact across the full product lifecycle, including raw material sourcing, manufacturing, use, and end-of-life. The assessment followed ISO 14040 and 14044 guidelines and considered four key environmental impact categories:
The results showed that Gii-based sensors had lower impact than both gold and carbon-based alternatives in almost every category. These results are consistent across all three sensor types modelled: a lateral flow-style sensor, a test strip-style sensor, and a test strip-style sensor with housing.
The report attributes these results to Gii’s simplified production method. Gii is manufactured using only a substrate and electricity, with no mined metals, chemical additives, or high-temperature processing. This avoids several of the most resource-intensive and emissions-heavy steps found in traditional material production.
The LCA findings provide a clear indication that Gii has the potential to offer a lower-impact alternative to conventional sensing materials. The results are intended to guide material selection, support responsible product design, and inform future sustainability efforts across iGii’s operations and partner network.
Gii isn’t just a high-performance sensing material it’s a smarter environmental choice. Our independent LCA shows that switching to Gii can significantly reduce climate impact, resource use, and waste compared to gold and carbon-based alternatives.
