A paper towel dispenser is a device that dispenses paper towels in a public restroom. It can be operated by a handle or by automatic dispensing in response to a motion sensor. These dispensers are common in North America and other Western countries. They are used to replace hand dryers or are used in tandem to offer users alternatives to dry hands. Some areas choose not to use them as towels to create garbage and are less environmentally friendly. The paper in the dispenser can be white or colored. Some are similar to paper towels and have perforations to allow them to be ripped off, while others consist of stacked sheets. A third kind of paper towel is torn by an integrated blade.
