“…The results demonstrated the efficacy of such modified biomass for biofuel production. The optimal parameters used during the process led to a 33.4% conversion of the raw material into biofuel, all at a temperature of 320 °C and a catalyst weight percentage of 5% (Echaroj et al 2021). Similar research focusing on biodiesel production was conducted by Saetiao et al (2023).…”

The increase in global population, expected daunting energy demands, and scarcity of resources has driven the search for new sustainable sources of materials, energy, and chemicals. In this context, biomass valorization has emerged as a promising technology to obtain high-value products in recent years. This research focuses on the valorization of rice production waste including straw, husk, and bran, due to their abundance, underutilization, and potential in generating a wide range of valuable products such as biofuels and materials. A systematic review was conducted regarding the valorization of rice production waste. The characteristics of biomass obtained from post-harvest rice production were explored, as well as the primary products derived from each of the discussed biomass feedstocks. Furthermore, the economic viability of the obtained products in their respective fields of application was evaluated, providing a solid foundation for future research and industrial applications. Different rice waste materials studied hold significant potential to obtain high‑value products including silica, adsorbent materials, biofuels, and various bioactive compounds.

“…However, high catalyst concentration produces unwanted by-products that plug the catalyst sites' pores, negatively affecting the catalytic and biofuel productivity processes. The sulfonated graphene oxide was used for the supercritical liquefaction of rice straw into ethanol (Echaroj et al 2021).…”

“…The total estimated cost for the production of graphene oxide is 4.574 dollars per gram in laboratory preparation, which should be lowered on an industrial scale (Tondro et al 2021). Reaction temperature of 320 °C, graphene oxide catalyst (10%), and sulfuric concentration of 6.0 mol were used for biofuel production from the liquefaction of rice straw (Echaroj et al 2021). The heating value of bio-oil was tested by protocol D4809.…”

Water pollution and the unsustainable use of fossil fuel derivatives require advanced catalytic methods to clean waters and to produce fine chemicals from modern biomass. Classical homogeneous catalysts such as sulfuric, phosphoric, and hydrochloric acid are highly corrosive and non-recyclable, whereas heterogeneous catalysts appear promising for lignocellulosic waste depolymerization, pollutant degradation, and membrane antifouling. Here, we review the use of sulfonated graphene and sulfonated graphene oxide nanomaterials for improving membranes, pollutant adsorption and degradation, depolymerization of lignocellulosic waste, liquefaction of biomass, and production of fine chemicals. We also discuss the economy of oil production from biomass. Sulfonated graphene and sulfonated graphene oxide display an unusual large theoretical specific surface area of 2630 m2/g, allowing the reactants to easily enter the internal surface of graphene nanosheets and to reach active acid sites. Sulfonated graphene oxide is hydrophobic and has hydrophilic groups, such as hydroxyl, carboxyl, and epoxy, thus creating cavities on the graphene nanosheet’s surface. The adsorption capacity approached 2.3–2.4 mmol per gram for naphthalene and 1-naphthol. Concerning membranes, we observe an improvement of hydrophilicity, salt rejection, water flux, antifouling properties, and pollutant removal. The nanomaterials can be reused several times without losing catalytic activity due to the high stability originating from the stable carbon–sulfur bond between graphene and the sulfonic group.
