iGii commissioned Anthesis to support the screening LCA of Gii-Sens

iGii commissioned Anthesis to conduct a comparative screening life cycle analysis (LCA) on our Gii-Sens Biosensors range to help us understand the carbon footprint of our manufacturing process in a 4-month project.

Gii Sens Biosensors range, powered by Gii – iGii’s pure 3D carbon nanomaterial with a large active surface area and innate antifouling properties offers a cost-effective, more sustainable, supply chain secure and scalable solution. They can be tailored to your needs with ultra-sensitive sensing for Point-of-Care Human and Veterinary Diagnostics, Environmental and Soil Monitoring and Food Safety applications.

With the single-step manufacturing process of Gii, we were confident that Gii had an overall lower environmental impact compared to other sensors on the market, especially those using precious metals as the sensing transducer, as these require mining and treatment that can involve toxic chemicals, large equipment, and heat.

We really wanted to understand what our carbon footprint is and areas for improvement as we are in the process of scaling up our manufacturing processes.

The comparative screening study looked at four categories across each sensor’s lifetime from cradle-to-grave in: climate change (carbon) impact, fossil resource use, water use and mineral/metal use.

We are pleased to share that the screening results have indicated that, compared to comparative technologies that use previous metals and screen-printed carbon, Gii-Sens Biosensors have a lower environmental impact of up to 900%.

Though the results were conducted independently and are yet to be verified, iGii are working on the next steps to verify these results and are taking on board the feedback from the study where we saw areas of improvement to further reduce our environmental impact for a more sustainable and supply chain secure future, with Gii.
