Where do tampons go?

Tampons should never be flushed, they should always be wrapped-up and binned.

Once flushed tampons don't break down but instead expand in the water, so they can get caught in pipes and collect over time to create blockages which can damage pipes as well as the surrounding area if the pipes burst. Blockages are often caught before there is major damage, a sewage worker will have to go down into the pipes to manually clear the blockages, what is removed (tampons along with other materials that people irresponsibly flush) is then disposed of in an incinerator.

Many tampons will find their way through sewage treatment plants, as these systems are not designed to deal with items like tampons, thus tampons can find their way into waterways like rivers or into the sea with other sewage and they end-up washing-up on beaches or eaten by sea life.
