Chang Robotics, an engineering company, and Northwestern University's INVO Lab have announced a joint venture aimed at reducing contamination from microplastics and poly-fluoroalkyl substances (PFAS) in the US food supply.  

This collaboration has led to the development of GOEco, an initiative that shows very small amounts of graphene oxide can be infused into paper products or compostable packaging materials to replace plastic and PFAS. 

GOEco's primary goal is to replace the widespread use of plastics in food packaging, such as paper plates and disposable utensils.  

The patent-pending technology helps enhance the environmental friendliness of disposable tableware without compromising functionality. 

Graphene oxide is a naturally occurring nanomaterial that comprises of carbon with some oxygen and hydroxide ions.  

The innovation was developed through a partnership between Dr SonBinh Nguyen of Northwestern University and Dr Tim Wei, a former dean of engineering.  

Their research focused on formulating graphene oxide and its application in disposable tableware, aiming to lead the market in sustainable packaging alternatives. 

Chang Robotics CEO Matthew Chang said: "The technology behind GOEco is a breakthrough that could impact not only our food supply but could play a critical role in protecting our reproductive ability and substantially increasing our health." 

Testing on the new packaging revealed that it offers superior food preservation qualities by preventing the transfer of moisture, oil, or gases, which could enhance food freshness compared to traditional plastic packaging. 

Wei and Chang Robotics have indicated that their laboratory testing and scientific literature review suggest the safety and sustainability of their graphene oxide application.  

The company is actively seeking industry partnerships and regulatory evaluations, including approvals, to confirm the safety of graphene oxide for food packaging use.
