Electricity is being  produced by paddy husk

An environment friendly sodium silica powder  manufacturing factory has been deeveloped by the private initiative of Chilarang Union of the Thakurgaon district  headquarters.  Rice bran is used as raw aterial.  Silicaisbeing produced by the generator engine with the gas produced by burning the chaff.

As the factory has been established, besides creating employment for the people of the area, the authorities are selling silica at Tk 140-150 per kg.

The company called Sustainable Energy and Agro Resources Limited is producing sodium silica powder commercially through the process of caustic dissimilation of sodium silica powder from paddy husk.
According to the factory officials, if the husk obtained after processing rice from rice is burned in the factory instead of being thrown away, 60-70 percent silica can be obtained from it. It can be commercially marketed by caustic acidification to form sodium silicate. And that is what is being done. The company is playing a role in meeting the needs of the country.

First, a certain amount of rice bran ash is measured and taken to the digester and treated with caustic soda. The dissociation process is carried out at 100-150°C for one to two hours. The smoke that comes out from here is used to generate electricity without letting it out. The entire unit is supplied with the generated electricity. It does not require external electricity. The liquid sodium silicate is then filtered through a 2-3 micron filter. It contains pure liquid sodium silicate.
The company started its journey in 2010, but after installing the parts and training the employees, the production started from March this year. Although the production capacity of the factory is two metric tons, about 500 kg of sodium silicate is being produced per day, the authorities said.

Water is evaporated through the process to maintain the water content of the sodium silicate as required. This pure sodium silicate is then marketed in drum packs. The effluent from the filter is dried and marketed through activated carbon drier.


Engineer Manik Hossain, the director of the institute, said, 'We are using rice bran to make silica. This plan is first in the district. The whole process is environment friendly. Hopefully, through this it is possible to meet the demand of silica in the country to some extent.'
