Tomato skin to replace carbon black in tyre manufacturing.Generally the filler used in rubber tyres is the carbon black, a petroleum product. This is for strengthening the tyre and improving the life. Now a research result from Ohio State University shows an alternative for carbon black. It is nothing but the outer skin of tomato. The research states that the tomato skin is thick enough and rich with fibre. This skin withstands high temperature. Tomato skin is mixed with the outer shell of egg which has small holes. This help increasing the surface area of tyre. This mixture of tomato skin and egg shell add to the hardness of tyre. Only difference will be in the colour of the tyre, it will be a bit reddish.
