Research of ricehuskash

Transform "ashes" into exquisite synthetic gems. State-of-the-art works of Thai researchers

Glass production from agricultural waste materials Invented and researched by Dr. Chakrabongse Kaewkhao, professor of science and technology. Nakhon Pathom Rajabhat University Starting from our country, we currently use quite a lot of biomass electricity. What is waste from the power plant is leftover ashes In the past, rice husks were used to burn. But lately, agricultural products are used to burn, such as rice straw, sugarcane waste, what remains is not rice husk because the husk is now in short supply. the rest is ashes which is worthless waste And it is also air pollution. because ashes can be blown into the air When inhaled, there are problems with the respiratory system. causing various pollution. As seen here, these ashes were taken for analysis. It was found that the ashes contained silicon dioxide. which is found only in some types of ash such as rice husk ash, straw ash, palm oil, sugarcane, etc. High silicon oxide Can be used to produce glass materials.
Therefore, research has been developed by applying it to create synthetic gemstones from glass. It turned out that the response was good, and many companies were interested because it was jewelry made from ashes. Only some chemicals that are not toxic to the environment are mixed. through high temperature annealing Finally, you will get different colored glasses. and make jewelry which is called synthetic jewelry Now it has begun industrial production.However, I would like to suggest that if there is an ash source near the smelting plant is to set up a factory near Most ash carriers to save transportation costs It turns industrial waste into valuables.
