Revolutionary Grain-Based Plant Leather Aims to Transform Sustainable Materials Industry
August 27, 2025
Uncaged Innovations is developing grain-based plant leather that mimics real leather in feel and even smell, signaling a major shift in sustainable materials.
In production, the material is layered on a plant fiber backing and can include a 0.01 mm bio-based polyurethane layer to adjust appearance and hand feel; it is biodegradable, pigmented and textured, with potential for scented variants.
Pricing sits in the mid-market range, with small orders under $10 per square foot and larger orders potentially at about half that price, underscoring environmental and cost advantages.
The product is already used in vegan-friendly handbags and watch straps, with automotive testing underway; heat resistance is the main hurdle, as tests show performance up to 85 C for 500 hours.
There is broader industry interest in alternatives to traditional leather driven by environmental and ethical concerns.
Hyundai’s Cradle division is collaborating with Uncaged to refine the material for automotive use, aiming for a durable, animal- and climate-friendly leather replacement with a claimed 95% lower carbon footprint.
Automakers are showing interest as Jaguar Land Rover has also partnered with Uncaged to explore plant-based leather alternatives.
Researchers are working to improve the process to emulate leather’s chemical structure by creating fibril-like plant protein architectures to achieve texture close to animal leather.
The story sits within a historical context of leather alternatives, driven by ongoing experiments and consumer demand for authentic sensory qualities like feel and scent.
