Cotton T-Shirt Life Cycle Revealed High Production Waste
New research shows that nearly half of raw cotton is lost before a shirt ever reaches your closet.

Should governments prioritize regulating manufacturing waste over enforcing consumer textile recycling?
A study tracking a cotton T-shirt from production in Bangladesh to disposal in Norway found that 44 percent of fiber is lost during the manufacturing process. The findings illuminate the significant environmental footprint required to produce a single 3.9-ounce garment.
Why it matters
Understanding these losses is critical for consumers aiming to make sustainable choices, as the manufacturing process currently necessitates 6.9 ounces of raw cotton for every finished shirt. This highlights the gap between current production practices and the European Union mandate requiring textiles to be highly recyclable by 2030.
Researchers at the Norwegian University of Science and Technology and SINTEF conducted a life cycle assessment mapping a cotton T-shirt's journey. The study found that 44 percent of cotton is discarded during spinning, dyeing, and cutting, contributing to 7.7 pounds of CO2-equivalent emissions per shirt.

Norwegian University of Science and Technology
An academic institution focused on sustainability research and lifecycle modeling.
SINTEF
A research organization providing expertise in industrial processes and environmental impact assessments.
The details
The production process loses 1.7 ounces of fiber during the combing stage alone, forcing manufacturers to rely on high volumes of raw material. Mechanically recycled fibers currently struggle with durability, requiring them to be blended with fresh cotton for reuse. While the European Union has mandated separate textile collection as of January 2025, current recycling infrastructure limits the recovery of these discarded fibers.
Timeline
January 2025: European Union mandate for separate textile collection began.
October 4, 2026: Study findings were published in the Journal of Circular Economy.
2030: Deadline for EU textile recyclability requirements.
Health Landscape
This analysis provides a critical update to the global textile industry's shift toward circularity and waste reduction. It frames current production practices against the European Union's 2025 separate textile collection mandate, which aims to address the 60 percent of textiles currently ending up in mixed waste.
Consumers can consider prioritizing durable, high-quality garments to reduce the frequency of textile disposal and help lower the industry's demand for raw cotton. It is worth discussing the benefits of circular textile economy labels with your local retailers to better understand the provenance of your clothing.
The takeaway
The high volume of waste generated during T-shirt production suggests that manufacturing efficiency is as important as recycling. Consumers should look for clothing brands that transparently report their fiber recovery rates and utilize recycled textile blends.
