- Rudyard Lake sediment core spanning 1876–2022 yielded textile fibers, creating a 150‑year chronology of human textile activity.
- Keele University researchers, together with Loughborough University, identified that all fibers recovered between 1876 and 1979 except two were cotton or wool.
- Deirdre McKay of Keele University said the results directly challenge the idea that natural fibers simply biodegrade and disappear once in the environment.
- iScience published the study in 2026, marking the first investigation of natural textile fiber preservation in aquatic sediments.
- Tom Stanton urged environmental researchers to incorporate natural textile fibers into pollution assessments to avoid new problems from “green” material substitutions.
- Leek historic mill town lies less than three miles upstream of the lake, linking the sediment record to historic textile manufacturing.
Why it matters: Sustainability strategies that rely on natural fibers as a quick‑degrading alternative to plastics are undermined, prompting fashion companies, regulators, and consumers to reassess material choices, marketing claims, and policy guidelines, as the evidence shows cotton and wool can accumulate in sediments for centuries.
