Challenges of Natural Rubber Supply
Natural rubber is essential to tire production, comprising 20-40% of a tire's weight, yet its supply is facing significant challenges. The world's major producers, Thailand and Indonesia, have encountered unexpected production drops due to poor weather, leading to volatility in global rubber prices. This instability is exacerbated by logistical challenges, including delays in shipments caused by geopolitical conflicts, which have increased freight costs and disrupted supply chains. As a result, tire manufacturers have paused rubber purchases, causing prices to plummet, further complicating their profitability amid rising demand in the booming Indian automobile market.
The Need for Sustainable Alternatives
Tire manufacturers are exploring sustainable materials and recycling methods to address both economic and environmental challenges. Companies like Apollo Tires are investing in research to develop bio-based materials and incorporating recycled rubber from used tires into their production processes. However, while these efforts are commendable, the issue of tire and road wear particles (TRWPs), which contribute significantly to microplastic pollution, remains. Significant research into reducing harmful chemicals like 6-PPD is necessary for true sustainability, as current alternatives may compromise tire durability and ultimately lead to more environmental harm.
