Through its remarkable mechanical, electrical, and thermal qualities, graphene has become a revolutionary material in electronics. Sustainable graphene synthesis from biomass residues offers a possible path toward adhering to the demand for economical and ecologically friendly graphene production methods. The present study thoroughly examines the numerous biomass sources used for graphene synthesis, such as plant-derived materials, agricultural waste, and other organic leftovers. The benefits and drawbacks of several synthesis methods are examined, including pyrolysis, chemical exfoliation, and hydrothermal carbonization. The study also explores the possible uses of graphene produced from biomass in electronics, including sensors, energy storage devices, electronic devices with flexibility, and electromagnetic interference (EMI) shielding. This review highlights how biomass-based graphene can revolutionize the electronics sector by bridging the gap between electronic applications, synthesis techniques, and biomass supplies.
