ABSTRACT
Clothing is a basic human need, yet the way we clothe ourselves today is fundamentally unsustainable. The fashion industry is one of the largest contributors to global carbon emissions and water contamination, and the industry yields more than 100 million tons of textile waste each year. The Recycled Textile and Apparel Manufacturing Ecosystems (RETAME) project brings together academic researchers from engineering, design, and the social sciences, industry partners, and the non-profit organization, Goodwill Industries, to build a sustainable recycled materials model for the textile and apparel industry. By converting post-consumer fashion waste into new products, RETAME keeps clothing out of landfills, generates revenue from existing waste streams, and reduces the need for virgin materials. The project focuses on the development of 1) novel mechanical recycling technologies, 2) product prototypes made from recycled fibers and textile pieces, and 3) educational and skills training programs for job seekers and students, especially those from underrepresented and disadvantaged groups. The project will yield a model recycling ecosystem to grow the Delaware Valley regional economy and improve the environmental sustainability of our clothing. Team members will document and evaluate the project at every stage to develop best practices for implementing the model in other regions.
The overarching goal of RETAME is to gather proof of concept for a sustainable recycled materials model for the textile and apparel industry that can be replicated in regions across the United States and around the world. RETAME accomplishes this goal by leveraging regional expertise and locally available waste materials. Team members are experts in sustainable textile design; engineering design; textile science; cultural anthropology; textile manufacturing and recycling; educational curriculum development and implementation; diversity, equity, and inclusion; and non-profit management of used clothing collection and retail.
The project involves the following methods and approaches: 1) the recruitment of collaborators in areas of waste and recycling policy, waste management, consumer science and behavioral economics, supply chain and logistics management, regional economic development, and environmental justice; 2) the design and testing of an aggregation, sorting, and mechanical textile recycling supply and production chain in the Delaware Valley region in partnership with Goodwill Industries; 3) the advancement and piloting of mechanical recycling technology and equipment for converting post-consumer clothing waste into reusable fibers; 4) the development of next-generation recycled textile composite prototypes; 5) analysis of the materials properties of recycled textile samples and the collection of initial data on the life cycle impact of relevant processes and products; and 6) ethnographic research and analysis of team-building, knowledge sharing, and convergence research strategies to yield results that will support the ecosystem model?s transfer and application to other regions.
Broad-based convergence research is necessary to build robust partnerships that can generate circular, sustainable ways of clothing ourselves. RETAME leads this effort by modeling the development of post-consumer fashion waste recycling and manufacturing systems that also support sustainable, regional economic development.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

ReSpool: Transforming Fashion Waste into Regional Textile Innovation
From 2023 to 2025, the ReSpool project brought together engineers, designers, scientists, and community partners to tackle one of the fashion industry’s most pressing challenges: textile waste. The ReSpool team developed new technologies and systems that transform discarded clothing into high-quality recycled textile materials—building a regional model for circular textile innovation. ReSpool's core innovation lies in its waste-led approach—designing processes and products based on what is already available in the waste stream. The team built a prototype Fiber Shredder, a mechanical recycling device that converts discarded apparel into reusable fibers, now refined and tested at lab scale,. In parallel, the team developed machines to speed up the removal of buttons and zippers, reducing labor costs and material contamination. ReSpool fibers, produced from cotton, polyester, rayon, and wool garments, were turned into yarns and nonwoven fabrics using thermal bonding and needle punching. Testing showed that yarns made with up to 85% recycled fibers maintained strong performance, while nonwoven fabrics made from higher percentages of recycled fibers were more breathable, making them suitable for applications such as weed-suppressing mats for environmental restoration.
Building a Regional Network. ReSpool established strong regional partnerships in the Delaware Valley and the Upper Midwest, working with nonprofit leaders like Goodwill Industries, small textile brands, and manufacturers. ReSpool also engaged in 21 interviews and extensive ethnographic research to understand the challenges and needs of community members, consumers, and industry stakeholders. These insights directly shaped future technical decisions, like investing in safe chemical separation for polyester and addressing risks of microplastic pollution during mechanical recycling.
A Model for Circular Systems. Beyond technical development, the team’s design thinking approach supported open communication across disciplines, allowing for deep collaboration between academic researchers and industry practitioners. Findings from qualitative team interviews helped clarify goals and improved collaboration throughout the project. This transparency and reflexive practice are now being developed into educational modules for use in design programs and industry training, supporting the spread of circular practices across the textile field.
The broader impacts of ReSpool are substantial:
- Environmental: Diverts large volumes of post-consumer textile waste from landfills and gives new life to used clothing through high-value applications.
- Economic: Supports green job creation through workforce training with Goodwill and partnerships with women- and minority-owned businesses.
- Educational: Trains the next generation of sustainable designers and engineers—supporting 5 graduate students and 13 undergraduates during the grant period.
- Social: Centers equity by partnering with organizations that serve underserved populations, ensuring that the benefits of this innovation are shared widely.
Encouraged by strong results and stakeholder enthusiasm, the ReSpool team is now preparing to scale up their technologies, deepen community partnerships, and further develop a transferable model that other regions can adopt. With its unique blend of science, design, and social impact, ReSpool is creating a future where fashion waste is not a problem—but a resource.
