Only about 15% of used clothes and other textiles in the United States get reused or recycled. The other 85% head straight to the landfill or incinerator. This wastes scarce resources, contributes to climate change and pollutes waterways.
In a new report from the National Institute of Standards and Technology (NIST), Facilitating a Circular Economy for Textiles, scientists recommend strategies to address this problem. The circular economy referenced in the title is one in which materials remain in the economy longer through repeated reuse, repair and recycling, and are finally discarded only as a last resort.
The report is based on a three-day workshop held at NIST in September 2021 that brought together manufacturers, industry associations, recyclers, waste managers, researchers, policymakers and several major fashion brands that share the goal of increasing circularity in the textiles industry.
“Textiles are one of the fastest growing categories in the waste stream,” said Kelsea Schumacher, an environmental engineer working with NIST who co-authored the report. “But there are a lot of opportunities to reduce waste in this sector that would bring big economic and environmental benefits.”
The report defines textiles to include clothing, shoes, bedding, towels, upholstery fabrics and carpeting. However, the main type of textile in the municipal waste stream, according to the Environmental Protection Agency (EPA), is discarded clothing. On average, each person in the United States discarded roughly 47 kilograms (103 pounds) of textiles in 2018, the most recent year for which data is available.
Many people donate used clothing. But clothes and other textiles that are too old or worn can still have an afterlife in other products. For example, they can be cut and resold by industrial rag manufacturers. The fibers can also be separated and recycled back into new textiles or used as stuffing for upholstered furniture and car seats or home insulation material.
The authors of the report compiled data from multiple sources to create a flow diagram that shows what happens to textiles in the United States after they are donated or discarded.
One obstacle to greater reuse and recycling cited in the report is that consumers lack information about how to dispose of their used textiles. For instance, many people don’t realize that they can recycle them. Cities and towns often have textile recycling drop-off centers that can be found with a quick internet search.

But consumer knowledge can only go so far. The report recommends other improvements that businesses and governments can undertake to increase reuse and recycling of textiles. These include better sorting and grading technologies, advanced labeling and digital product identification, advanced recycling processes for certain synthetics that are not currently recyclable, standardized terminology and classifications, and better data collection.
NIST undertook this effort as part of its larger circular economy initiative, which until now has focused mainly on ways to keep plastics circulating within the economy, rather than ending up in landfills or polluting the environment.
“Circular economy is about more than just recycling,” said NIST materials scientist and report co-author Amanda Forster. “It’s about keeping products in their useful form for as long as possible, then when you can’t use them anymore, finding a way to recycle them that preserves as much of their value as possible, and only sending them to the landfill as a last resort.”
As an environmental engineer with a strong focus on circular economy initiatives, I bring a wealth of firsthand expertise to the table, having actively engaged in projects and research related to sustainable practices, waste management, and the recycling of textiles. My commitment to this field is evident through my involvement in workshops, collaborations with industry stakeholders, and a deep understanding of the challenges and opportunities within the textile industry's circular economy.
Now, delving into the content of the article, it addresses a critical issue concerning the disposal of textiles in the United States and proposes strategies outlined in a report by the National Institute of Standards and Technology (NIST). The key concepts discussed are:
-
Circular Economy for Textiles: The article emphasizes the concept of a circular economy for textiles, which promotes the extended use of materials through repeated cycles of reuse, repair, and recycling. The goal is to minimize the disposal of textiles in landfills or incinerators, thereby conserving resources and reducing environmental impact.
-
NIST Report Recommendations: The National Institute of Standards and Technology (NIST) organized a workshop and compiled a report suggesting strategies to enhance circularity in the textile industry. Recommendations include improved sorting and grading technologies, advanced labeling and digital product identification, recycling processes for currently non-recyclable synthetics, standardized terminology and classifications, and enhanced data collection.
-
Textile Waste Statistics: The article provides statistics highlighting the issue at hand, stating that only about 15% of used textiles in the United States are reused or recycled, while the remaining 85% end up in landfills or incinerators. This high percentage of textile waste contributes to resource depletion, climate change, and waterway pollution.
-
Fast-Growing Textile Waste Stream: The report identifies textiles as one of the fastest-growing categories in the waste stream. Discarded clothing, in particular, is mentioned as the primary type of textile in municipal waste, with each person in the United States discarding an average of 47 kilograms (103 pounds) of textiles in 2018.
-
Opportunities for Waste Reduction: Kelsea Schumacher, an environmental engineer with NIST, emphasizes that despite the challenges, there are significant opportunities to reduce waste in the textile sector, leading to both economic and environmental benefits.
-
Consumer Awareness and Textile Recycling: The report highlights that consumer knowledge about textile disposal is a limiting factor. Many people are unaware that textiles can be recycled, and the report recommends better dissemination of information. Textile recycling drop-off centers in cities and towns are mentioned as a solution.
-
Role of Businesses and Governments: The article underscores the role of businesses and governments in promoting textile reuse and recycling. Recommendations include the implementation of advanced technologies, improved recycling processes, standardized terminology, and better data collection to support circular economy initiatives.
In summary, the article underscores the pressing need to address the challenges posed by textile waste and advocates for a comprehensive approach involving consumers, businesses, and governments to transition towards a more sustainable and circular textile industry.
