Winner of "Encouragement Award for 21st Century Inventions", and "21st Century Contribution" from the Japan Institute of Invention and Innovation.
Giving new purpose to discarded waste
TriporousTM is produced entirely from discarded rice husks
TriporousTM is produced from 100% biomass. Sony's technology reuses surplus biomass to make TriporousTM, which may help to reduce environmental impact.
Annual disposal of rice husks by region
Worldwide, about 150M tons are discarded per year
What is TriporousTM?
TriporousTM outperforms activated carbon
The unique microstructure of TriporousTM makes it effective for adsorbing gas and odour. It also offers superior performance in removing larger organic substances from liquid, such as the bacteriophage MS2, compared to the coconut-husk-based activated carbon adsorbent typically used in water purification.
