UNSW Sydney researchers have developed a method to produce high-quality graphene from waste peanut shells, which could lead to more sustainable and affordable electronics and energy storage solutions. The process requires less energy and no chemicals compared to traditional methods.

Graphene, known for its strength and conductivity, is vital for applications in batteries, solar panels, and flexible electronics. With 55 million tonnes of peanut waste generated globally each year, this method presents an opportunity to convert agricultural by-products into valuable materials, addressing both cost and environmental concerns in graphene production.
