Fawy et al. developed a dual valorization technique to convert lignocellulosic biomass (specifically rice husk and straw) into amorphous silica and activated carbon for the construction industry. The process involves: (1) pre-treating biomass with 50 g L−1 alkaline solution, (2) neutralizing with acid to pH 7 to precipitate sodium silicate, (3) converting sodium silicate to amorphous silica, (4) lowering the filtrate pH to 1–2 to precipitate biomass components, and (5) carbonizing the dried precipitate in a tube furnace at 800 °C for 8 hours under N2/CO2 gas flow.
