Fascinating Facts About Rice Husks

Fascinating Facts About Rice Husks

The humble rice husk, an outer covering for every kernel of rice, was once considered as an agricultural waste.  Farmers were in quandary on how to dispose of the over-abundance of rice husks when grains of rice are separated from the cover. They were often dumped into various refilled lands and the sea as a result.

Enter new research and development. The rice husk is extremely useful and applied in different industries.  Consider its properties.

  • High silica content
  • Resistance to fungal decomposition
  • Resistance to moisture penetration
  • Slow decomposition
  • Good insulator
  • Great as renewable energy

When you think about it, these properties lead to multiple usages especially in developing countries:

  • As electricity for villages
  • As power for lights
  • As building materials
  • As fuel for bricks
  • As alternative materials to wood chips
  • As a source for silica and silica compounds

Interestingly, the ash from rice husks is also used as renewable energy.  Known as Rice Husk Ash or RHA, the applications include processing of steel, cement, and refractory industries. RHA has also been found to be superior to other supplementary materials like slag, silica fume and fly ash.

Commercially, rice husks are a good and sustainable source for daily living. Husks Green International have innovatively adopted the use of rice husks to produce smart dining and packing solutions for modern living.

From food packing and dining cutleries to kitchen ware, the opportunities are immense and applauded.
