A process to treat the rice husk and straw by using chemical agents to obtain valuable products with industrial impact. The source of the rice husk and straw is the residuals of Hassawi rice. Focus is on integrated large-scale production of silica that is separated from the one-pot continuous process as raw materials. It also feeds the paper industry with a massive volume of pulp produced after silica extraction for value-added materials. The process includes alkaline treatment of washed husk and straw after shredding to increase the applied pH to certain values. The obtained products are mesoporous silica, activated carbon, graphene oxide, lignocelluloses, pulp, lignin-free cellulose. The obtained materials can serve in the production of glass, ceramics, catalysts, super capacitors, bio-fuel, salt-free water, anti-cancer agents, drug delivery and printing paper. The obtained products can be applied in water treatment and in pharmaceutical and biomedical applications.
