GO-Eco

GO-Eco is a green technology startup and subsidiary of Chang Robotics that specializes in sustainable, PFAS-free alternatives for food packaging. Developed through a collaboration between Northwestern University researchers Dr. SonBinh Nguyen and Dr. Timothy Wei, the company leverages a proprietary graphene oxide nanomaterial. This material is integrated directly into paper fibers to create a non-toxic, recyclable, and compostable barrier that provides superior resistance to moisture, oils, and gases compared to traditional solutions. By enhancing the strength and barrier performance of paper-based products, the technology offers a functional replacement for conventional plastic and synthetic coatings that contain toxic forever chemicals.

The company addresses critical environmental and public health concerns by providing a scalable, cost-competitive material that helps eliminate PFAS and microplastics from the food supply chain. Designed for applications ranging from molded fiber tableware to corrugated cardboard, the technology aims to reduce environmental waste while maintaining high performance. GO-Eco is currently focused on scaling its production, completing comprehensive industry-standard evaluations, and securing FDA food-contact approval to bring its materials to the mass market. The venture has gained significant industry traction, engaging with numerous partners for pilot-scale production trials to facilitate the transition from laboratory research to commercial use.
