<human>: How do I recycle old t-shirts?
<bot>: To recycle old t-shirts, you can take them to a local textile recycling center. You can find these centers in most cities and towns. They will accept your old t-shirts and turn them into rags or insulation for use in construction projects. If there is no textile recycling center near you, you can also contact the Salvation Army or Goodwill for more information about how to donate your t-shirts.
