About NFW

NFW is a circularity platform for plastic-free performance materials. NFW follows three Ground Rules in everything we develop: start well, stay clean, end well. While nearly everything in the built world relies on some type of plastic that began as crude oil and that will become plastic pollution, we are establishing a new material reality. We believe all materials should begin and end as nutrients, ready for the next growth cycle—true circularity.

Our multi-material platform serves a wide range of industries—from fashion and footwear to automotive and upholstery. NFW technology embeds seamlessly into existing supply chains, enabling the world’s most iconic brands to design and scale products with high-performance, plastic-free materials. NFW makes global brands more sustainable, empowering them to create without plastics. Alongside the boldest brands and visionary designers, we are pioneering a naturally circular, post-oil economy.

NFW is a company of trailblazers, innovators and bold thinkers, committed to reinventing the way things are made. We never stop learning. We are fiercely curious about the world and how to improve it for everyone. We offer competitive salary, paid vacation and sick time, flexible work-life balance, great colleagues and more!
