Natural Fiber Welding (NFW) is a Peoria, Illinois–based materials-science company that engineers high-performance, plant-based alternatives to petroleum-derived plastics. Its proprietary green-chemistry platform powers two flagship products: MIRUM, an all-natural, plastic-free leather replacement, and PLIANT, the world’s first naturally cured performance rubber outsole. Together these materials form a regenerative, circular platform aimed at footwear, fashion, automotive, and industrial markets. The company positions its solutions as drop-in replacements that match or exceed conventional materials on performance, durability, and aesthetics while radically lowering carbon footprints. NFW is seeing rising demand from global brand partners and has secured strategic backing from investors such as BMW iVentures, Ralph Lauren Corporation, Allbirds, and Asahi Kasei. The latest capital will be used to accelerate commercialization, expand manufacturing capacity, and support ongoing product innovation. No revenue or user metrics were disclosed in the article.
