Scientists from Hiroshima University have created a fairly environmentally friendly LED light emitter. An option to exploit the planet’s agricultural waste.

Several Japanese scientists have managed to turn rice husks into LED lights . This process eliminates the toxic materials used in the construction of these lights, which is a very important benefit to the environment.

The use of rice husks

It happens that rice undergoes various processes to become the white grain that is traditionally consumed. In fact the shell is removed.

However, these Japanese researchers decided to use rice husks to create LED-type lights . In this way, one type of luminaire appears to save energy made from natural material.

Rice becomes LED

The key is to harness the luminescent qualities of silicon, an element found in these grains. Additionally, this helpful element adds an articulate texture to the rice. Therefore, its microscopic spots give off luminosity.

To carry out the experiment, a quantity of shell milled with a heat treatment was used . In this way, crystalline particles with a fair amount of silicon were obtained. The result is a luminescent efficiency of 20%.

Subsequently, these microparticles were used to assemble the LEDs . The results were quite satisfactory, with the hopes of improving the obtaining of silicon from rice grains.

An interesting fact is that other natural materials can be used. For example, there is also silicon in bamboo, wheat grains, barley, and sugarcane receipts . Quite interesting information.

If this procedure is successful, agricultural residues can be used to produce lamps . Without a doubt, it is an excellent option for achieving ecological results in the production of lights.

For now, this procedure is in an experimental stage . However, the first results were positive. The silicon crystals obtained from rice, in fact, are able to emit a certain amount of light.

The pollutants used in the LED lights are eliminated

Above all, the need to use cadmium in this lighting technology is avoided. Keep in mind that cadmium is quite toxic. Therefore, broken LED lights must be disposed of carefully.

However, adequate procedures are rarely in place for the disposal of cadmium-containing materials. Therefore, alternatives were sought to replace this material. Perhaps what is discussed in this text is an option.

Can you imagine using rice for this purpose? Actually, what would the shell of this bean be for. It is a natural material that is always discarded, but which would now have an important use.
