It is an attempt to maximise exploitation of the precious silica and nano silica resources from rice husk, levera

Rice husks can be recycled into valuable input materials

Vietnam produces more than 40 million tons of unhusked rice a year, and In 2015 alone, the rice output was 44.7 million tons. Rice Husk. — VNS Photo. Rice husks account for 20 percent of rice grains. This means that 9 million tons of rice husks are discharged into the environment, a huge volume of waste which, if not treated, will cause pollution. Rice husks are difficult to recycle, and a kind of refractory material, difficult to decay in the environment. In Vietnam, and mostly used as fuel to burn. In the last few years, it has been processed into firewood or plywood sheets for interior decoration. However, the volume of rice husks used for these purposes remains modest compared with the h

Leaf Resources turns food scraps into silica

An Australian firm is gearing up to launch a process for turning rice husk and other plant waste into silica — one of the key components in computer chips. Leaf Resources, an ASX-listed firm based in Queensland, has lodged a patent application for its process, which it says will allow it to tap into the $US300 billion ($408bn) microchip industry. Leaf Resources managing director Ken Richards. “The United States Academy of Sciences said the industrialisation of biology will be as powerful for economic growth in the next 50 years as semiconductors were in the last 50 years,” Leaf Resources managing director Ken Richards told The Australian. He said his method extracted the innate silica within

Researcher creates innovative paint from rice husks

Dr Nguyen Thi Hoe is the foremost Vietnamese female scientist to successfully research and produce Kova paints using rice husk-derived nanomaterials to capture one of the hard-to-please Asian markets, Singapore. Hoe claimed that after more than 6 years, in 2012, her products were widely used in Singapore's supermarkets, 800-flat buildings, and airports. Dr Nguyen Thi Hoe (centre) and her assistants at their laboratory. — VNS Photo She recalled that more than 20 years ago, when she taught at the HCM City's Technology University, she alone left for the US in order to conduct research about paint. "Despite all odds, I received great help from the US partners, such as a laboratory for me to rese
