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.


Solving social issues through Triporous business

We contribute to improving the global environment and realize a sustainable,
prosperous life with our partners
