An Innovative New Material for
Purifying Water and Air

Turning Rice Husks into Gold

Sony’s latest innovation: Triporous, a porous carbon material made from rice husks.
Thanks to its unique patented microstructure with 3 different pore sizes,
Triporous offers potential applications in a wide range of fields,
such as water and air purification. By making use of excess rice husks,
Triporous will lead to technological breakthroughs in various areas including textiles,
bringing us closer to a recycling-oriented society.

Sustainability

Triporous is a new material made from rice husks, of which more than 100 million tons is generated worldwide each year. Recycling this surplus biomass contributes to the realization of a more environmentally conscious, recycling-oriented society.

Technology

The use of rice husks as a raw material gives Triporous a unique microstructure that enables easy adsorption of materials that are difficult to adsorb with conventional activated carbon. Adsorption is also much faster. Furthermore, the capacity of Triporous to carry a large quantity of active chemical agent opens up possibilities for many different functions.
