| Rice husks can be burned into ash that contains silica, a material with a wide variety of applications. |
Vietnam’s rice output in 2015 was estimated at 45 million tonnes, of which 9 million tonnes were husks, most of which used to be discarded or used in rudimentary brick kilns.
Rice husk ash contains silica, which can be used to make tyres, solar cells, ceramics and heat-resistant materials, among others.
According to an estimate, with the current price at VND600,000 for a tonne of rice husks, Vietnamese farmers could earn an extra VND5.4 trillion (about US$240 million) a year from selling the commodity.
This mean the value of rice husks is equivalent to 10% of rice exports.
The commodity can be exported or sold to domestic companies operating in this field.
On the world market, the price of amorphous silica varies greatly depending on its quality, with a tonne of silica for metallurgy costing US$500 and a tonne of high-quality silica for the production of solar cells selling at US$1,500.
