Abstract: Sustainability in the automotive sector has become a global priority as environmental pressures and regulatory requirements continue to intensify. This review examines the integration of recycled materials and innovative eco-friendly substances in vehicle design and production, highlighting their role in reducing environmental footprints while maintaining performance. Conventional automotive materials such as steel, aluminum, and plastics contribute heavily to greenhouse gas emissions and resource depletion, making the shift to sustainable alternatives essential. Recycled metals, plastics, rubber, and glass are increasingly adopted, offering significant energy savings, waste reduction, and cost efficiency. In parallel, advanced bio-composites, biodegradable polymers, and nano materials are being explored for their ability to provide lightweight, renewable, and high-performance options. These innovations not only reduce vehicle mass and emissions but also align with circular economy principles. Despite these benefits, challenges remain, including quality variability, safety concerns, and supply chain complexity. Nonetheless, ongoing advancements in recycling technologies, material engineering, and regulatory support are paving the way for broader implementation. Future trends point toward additive manufacturing, closed-loop recycling, and enhanced collaboration between industry, academia, and policymakers to accelerate adoption. Overall, sustainable material integration represents a vital pathway for the automotive industry to reduce environmental impacts, enhance resource efficiency, and meet global sustainability goals.
