This process in the near future could be used to transform 80 million tons of garbage into a valuable product.
Despite the fact that rice represents a staple crop in the majority of the nations, it is also the producer of a huge amount of waste.
It should be noted that on average 20% of all rice by weight is thrown away. Thus each year accounts for 80 million tons of inedible husks from today’s annual rice yield of 422 million tons.
These husks are tough and abrasive and can be used in low-cost materials like fertilizer additives or bed soil and nothing more. Nevertheless a team of scientists from South Korea managed to come up with a way of reducing the amount of agricultural waste from rice farming. They were able to turn the husks into a more precious finished product.
Researchers at the Chungnam National University were able to extract silica from the silicon-rich husks to turn it into silicon for battery anodes.
In spite of the way that molecularly rice silicon is indistinguishable to sand, the plant is the particular case that stores it in permeable nanolayers. This assumes the part of preventive measure against creepy crawlies and growths.
In this manner to concentrate the extravagant material, researchers needed to utilize a process that includes a few steps, including corrosive and hotness treatment.
The new system gives high-review hardware prepared silicon that is attractive for battery anodes in light of its electrochemical qualities.
