Objective:
The goal of this project is to develop a novel technology to extract both lignocellulose and nano-silica from waste rice husks. It is planned to conduct process optimization, process simulation, and economic evaluation, which in turn should help significantly minimize pollution and costs associated with the current disposal of rice husks and provide starting materials for biofuels and other products.
Progress Summary:
We have successfully developed an ionic liquid extraction approach to obtain both lignocellulose and silica nanoparticles from rice husk biowaste. The recovered lignocellulose can be used for biofuel and prepare bio-based surfactants. The silica nanoparticles from rice husks have been successfully converted to organo-silicon compounds, which can be subsequently used to synthesize various silicon containing materials. The silica nanoparticles can also be further converted to elemental silicon for various applications such as battery electrodes. Both process simulation and economic evaluation are underway. One of the student members has won several business project awards based on this project, and plans to set up a small business in the near future to commercialize this technology.
Future Activities:
Our research results so far have shown that rice husk biowaste can be converted to two valuable materials, lignocellulose and silica nanoparticles, as proposed. More detailed investigation is ongoing to optimize the process and further lowering the cost to eventually commercialize the process.
