The potential of reusing low-value biomass waste for the processing of renewable materials to fabricate high-value products is remarkable. In recent decades, a major impact has been witnessed in the economy and environment based on the conversion of biomass waste into valuable carbon nanomaterials. Various chemical methods have been developed to synthesize high-value carbon nanomaterials; however, the use of green technology for the synthesis of carbon nanomaterials is the most common nowadays because of the abundant availability of the starting precursors, their non-toxicity, low fabrication cost, ease of modification, and eco-friendly nature. The large-scale production of rice is associated with some valuable by-products (rice husk, rice straw, and rice bran) attributed to the presence of important components like lignin, cellulose, and hemicellulose. Carbon nanostructures made from rice waste have unique physicochemical properties like high surface area, porosity, and unique functionalities that have excellent potential to be applied to solve a wide range of environmental issues. The primary goal of this chapter is to draw attention to the recent developments in the synthesis of environmentally friendly methods of producing carbon nanomaterials, such as graphene, carbon nanotubes, and carbon dots, from rice biomass waste, their complete characterization, and their applications to solve the environment-related problems.
