NOVELTY - A bio-graphene film is synthesized by synthesizing bio-waste solution from powdered fish scales, where bio-waste solution is synthesized by adding 30-75 mg powdered fish scales into a boiling solution of 15-50 ml ethanol and deionized water (1:9 v/v); mixing carrageenan with bio-waste solution to provide 1st mixture, where carrageenan is selected from Kappa-carrageenan, iota-carrageenan, and lambda-carrageenan; adding graphene oxide to the 1st mixture to produce 2nd mixture; sonicating the 2nd mixture; and evaporative-casting the 2nd mixture to produce the bio-graphene film. USE - Synthesis of bio-graphene film. ADVANTAGE - The method facilitates recycling bio-waste to reduce the impact of landfills or other bio-waste disposal mechanisms on the environment.
