‘GO-Eco’ is emerging as a breakthrough in the race to eliminate PFAS from food packaging, offering a graphene-oxide-based barrier that matches — and often exceeds — the performance of conventional plastic and PFAS coatings. Developed by Northwestern University scientists and commercialised by Chang Robotics, the nanomaterial bonds directly to paper fibres, creating a recyclable, compostable, and biodegradable solution.

Lab tests at Western Michigan University’s Paper Pilot Plant confirmed GO-Eco’s superior water and oil resistance, along with a 27% increase in tensile strength and 56% in burst strength compared to current coatings. Early commercial momentum includes multiple NDAs, active testing with major packaging players, and upcoming pilot-scale production trials.

With regulatory pressure mounting to remove PFAS, GO-Eco offers a scalable, cost-effective path to safe, sustainable packaging without sacrificing durability or performance.
