Nearly 50% of all cotton T-shirts are wasted before purchase
Most debates about textile waste start at the closet, or at the donation bin. But a closer look at a basic cotton T-shirt suggests the biggest losses may happen long before a shirt is worn, washed, or thrown away. In a new analysis of two consecutive T-shirt life cycles, researchers found that about 44 percent of the original cotton fiber was lost during production, before the garment ever reached a store. Under current conditions, only about 17 percent of the initial fiber input could be mechanically recovered and used again in a new T-shirt. That finding shifts attention away from the usual end-of-life discussion and toward the factory floor. Here, spinning, dyeing, cutting, and sewing quietly erase a large share of the material that goes into clothing. “When we talk about textile waste, the debate often focuses on the clothes we throw away. But the problem starts much earlier,” explained former master’s student Rakib Ahmed at the Norwegian University of Science and Technology (NTNU), currently a researcher at SINTEF Industry.
