Rice biomass such as rice husk and rice straw contains up to 20% silica.
Rice husk silica is a renewable source of silca and has the potential to replace commercial silica products such as precipitated silica for the production of advanced composites.
We want to look at how we can extract this silca from rice husks as not only will this maximise the value of rice husk but it will also improve the sustainability of the rice industry.
This PhD project aims to develop a solvent-based biorefinery process to produce silica from rice husk and to assess the silica for the manufacturing of advanced composites.
