When it comes to green, you might instantly think of the environment how our resources slowly depleting as time goes by. Petroleum is one of the resources. USDA Agricultural Research Service scientists Lei Jong and Jeffrey Byars are now experimenting soy flour as green filler for tires and other natural rubber products. Mind you that soy flour is the key ingredient for cooking and baking. This could mean that the current tires filler used, a petroleum based particles called carbon black could be replaced by using defatted soy flour.

The green filler is currently subjected to testing on shear and other forces. They also conducted an experiment, storage modulus which measures the elasticity of a material. The result is on average the storage modulus scores of composite containing 30% soy flour are 20 times higher than filler free rubber. The researchers are collaborating with rubber manufacturers to further explore the technology. This is one of the technological advancement that we should look into. In the future, it is most likely that our car tires came from Soya bean literally.
