A rising trend in eco-friendly design is the use of plastics and composites derived from renewable natural sources, such as corn starch, sugarcane, or even agricultural byproducts. These bio-based materials reduce reliance on petroleum and often require less energy to produce. They are being developed for use in interiors, body panels, and trim, often with equivalent performance to their traditional counterparts. Beyond environmental benefits, bio-based materials may also be biodegradable, further reducing automotive waste at end-of-life.
