The electric vehicle (EV) market is growing quickly, and with it, the problem of excess tire wear. While EVs reduce greenhouse gas emission and the use of fossil fuels, they increase the amount of tire waste produced per year as their high torques, weight and speed drastically decrease the lifespan of tires. With EVs on the rise, discovering methods to manufacture tires efficiently and sustainably is crucial. One such method involves retreading tires, which increases their lifespan and minimizes tire waste. A major challenge stopping an industry transition to retreading is that there are thousands of unique tire designs used in passenger cars today, each requiring a specialized mold for conventional retreading. In addition to the issues with tire disposal, today’s passenger tires are made with a heavy reliance on unsustainable materials. A key example is carbon black, the main reinforcing filler used in tire manufacturing, a petroleum-based product that can produce upwards of 2.62 tons of CO2 per ton of material. Finding a greener alternative to these materials and methods is crucial to Silpara’s goals of increasing sustainability in the rubber industry. A previous capstone group working with Silpara perfected the formulation of their sustainable fully bio-based rubber. Our project aims to optimize this formulation further for additive manufacturing techniques. This methodology would circumvent traditional molding techniques, enabling for sustainable development of tires that would contribute to UN SDGs 3, 7, 12 and 13.
