Professor Richard, Department of materials science and engineering, University of Michigan, USA. Ryan has successfully developed the use of rice husk ash, agricultural waste as raw materials, new production technology of white carbon black.
　　According to reports, this new technique is using containing sodium hydroxide of ethylene glycol and ethanol solution weakened between silica and rice husk ash chemical bonds in silica dissolved in liquid, then the liquid silica from solution in distilled and processed into suitable for the industrial application of the precipitation method white carbon black. According to estimates, the cost of the method is reduced by about 90% compared to the current conventional production process, and almost no greenhouse gas emissions.
　　Richard。 Ryan is now in the state of Michigan Ann Arbor founded a company called Maya Si Er, committed to the commercial application of this new technique. The company is building a pilot plant in order to verify the process of industrialization.
