Rice is the second most consumed food, globally. Rice husk, which is the by-product of rice production, can be used as bio-mass fuel in green energy production.

 

However, the result is rice husk ash, which is a waste.

 

The use of rice husk in the production of Bio-based nanoporous silica is a revolutionary technique in which waste is utilized to create a nanomaterial of high purity and value.

 

Rice husk ash is rich in amorphous silica, making it a highly customisable and renewable source of silica. This conversion from ASH to CASH is a sustainable development initiative to reduce the ecological footprint toward building a circular economy model .
