USER SUBMITTED QUESTION

How many pounds of used tampons are discarded in the United States each year?

U.S. annual discarded tampon mass

THE DISGUSTING NUMBER

34,722,806 pounds (15,750,000 kilograms) of dry tampon-and-applicator product mass per year

Answer basis: U.S. ANNUAL TOTAL

WHAT THAT MEANS IN REGULAR ENGLISH

No lab coat required.

Using 7,000,000,000 annual U.S. discards and a representative dry product weight of 0.08 oz (2.25 grams), the modeled total is 34,722,806 pounds (34,722,806 lb (15,750,000 kilograms)) per year. It covers combined disposal pathways, not a measured sewer-versus-trash split.

HOW WE DID THE MATH

Convert the documented 2.25-gram product weight to 0.004960400899 pound, then multiply by 7,000,000,000 discarded tampons. The result is 34,722,806 pounds (34,722,806 lb (15,750,000 kilograms)) of dry product mass per year after rounding to whole pounds.

7,000,000,000 tampons × 0.004960400899 pound per tampon = 34,722,806 pounds per year

ASSUMPTIONS AND LIMITATIONS

Evidence mode: BOUNDED ESTIMATE. Scope adjustment: The original wet-mass question was narrowed to a U.S. annual dry product-mass estimate. It combines all reported disposal pathways rather than estimating trash and sewer shares separately, and it excludes absorbed fluid and separate packaging because neither was measured in compatible national data. Uncertainty: This is a bounded proxy, not a measured waste-stream total. The annual discard count is an institutional secondary estimate, while the unit weight represents one regular compact-applicator product; actual mass varies with absorbency, applicator design, packaging, fluid loading, and the true annual count. The calculation applies the documented 2.25-gram weight of one regular compact-applicator tampon to all 7,000,000,000 discarded units. The converted unit mass is 0.004960400899 pound. It does not assume a wet-fluid load or a split among landfills, sewage lines, and oceans.

See the publication copy
Americans discard an estimated 34,722,806 pounds (34,722,806 lb (15,750,000 kilograms)) of dry tampon-and-applicator product mass per year. That estimate multiplies 7,000,000,000 discarded tampons by a representative FDA-filed weight of 0.08 oz (2.25 grams) each; absorbed fluid and separate packaging are excluded.
