Graphene materials attract significant attention due to their potential applications in transistors, conductors, batteries, catalysts, and biosensors. Various materials have been used to produce graphene, however applications for use are limited due to its high cost. There are an estimated 50 million tons of lignin available from pulping processes world-wide every year. Most of the lignin is burned onsite to provide energy. This research has developed a simple, cost-effective experimental process to produce graphene materials from the second most abundant polymer on Earth - lignin. The availability of a much larger quantity of lignin graphene at a much lower cost will have a huge impact on the development of lighter and stronger structural materials for the automobile, aerospace, and building industries.
