    About 30% of an ordinary car tire is carbon black, which is used to increase the durability of rubber Carbon black is the product of incomplete combustion or thermal decomposition of carbon containing substances such as petroleum under the condition of insufficient air, which means it is not an environment-friendly product Now a team of Ohio State University scientists led by Katrina Cornish are trying to develop a more environmentally friendly alternative with eggshells and tomato skins The researchers obtained eggshells and tomato skins in the form of food industry waste, dried them, and then ground them into powder When these powders are added to the rubber, the rubber becomes stronger while maintaining its elasticity (by contrast, most reinforcements reduce the elasticity of the rubber), the researchers said The researchers believe that this is because porous eggshell particles have a large surface area, allowing contact with rubber, while tomato skin particles are highly stable at high temperatures, plus they contain tough fibers Previously, Ford Motor Company and Heinz Group researchers had announced cooperation to manufacture auto parts from dried tomato skins Scientists at Tuskegee University have been using eggshells to make bioplastics Cornish said the technology from Ohio State University should contribute to the sustainability of tire production, reduce dependence on oil, and make effective use of food industry waste from landfills Source: cnbeta.com
