Hyundai is working with a startup on plant-based leather that smells like the real thing

Hyundai is teaming up with Uncaged Innovations, a startup specializing in sustainable materials, to develop a new type of plant-based leather that not only mimics the feel of traditional leather but also offers significant environmental advantages. Unlike typical synthetic leathers made from fossil fuel-derived plastics, Uncaged’s product is primarily crafted from agricultural grains such as wheat, soy, and corn, providing a more eco-conscious alternative. Stephanie Downs, co-founder and CEO of Uncaged, emphasized the variety in leather types, stating, "Leather is not just leather. There’s literally a thousand types of leather: different animals, different thicknesses, different ways that they tan it." The collaboration with Hyundai’s Cradle division aims to refine this innovative material for use in vehicles, with a focus on creating a durable, animal-free alternative that significantly reduces carbon emissions—by up to 95% compared to conventional leather. The automotive industry has a long history with leather alternatives, dating back to the early 20th century when the Ford Model T featured basic faux leather. While advancements have been made, many synthetic options still fall short of replicating the genuine leather experience. Uncaged’s materials, which are already being used in vegan handbags and watch straps, are poised to capture the attention of automakers, who face substantial costs associated with sourcing genuine leather. Each vehicle interior can require between two to fourteen cowhides, depending on the design and quality standards. Scar marks from outdoor living often result in a considerable amount of leather being wasted. In contrast, Uncaged’s factory-produced material ensures uniformity and reliability. Pricing for this alternative leather is competitive, with smaller orders costing under $10 per square foot, and larger orders potentially halving that price, according to Downs. Uncaged is currently conducting tests for several automotive manufacturers, focusing on heat resistance as a key challenge. Downs noted that one company is aiming for the material to withstand temperatures of 95 degrees Celsius for 500 hours, and they have already achieved 85 degrees Celsius under similar conditions in initial tests. The innovative process involves replicating the chemical structure of animal leather to enhance the product's authenticity. By experimenting with a variety of plant-based ingredients, Uncaged has developed a method to create fibril structures that resemble those found in leather. The final product features a biodegradable backing and may include a thin layer of bio-based polyurethane to enhance appearance and texture. Additionally, Uncaged offers customizable features, including color and texture options, and even the ability to infuse unique scents derived from floral extracts. Downs revealed that some automotive companies are interested in developing signature scents, while handbag manufacturers have also inquired about incorporating their fragrances. As innovation in plant-based materials progresses, the automotive industry stands to benefit from more sustainable and customizable options that align with the growing demand for environmentally friendly solutions.
