One or more techniques and/or systems are provided for waste object detection. For example, a waste alert component is configured to emit ultraviolet light towards a waste detection zone, such as a bathroom floor or countertop. If a waste object, such as a paper towel or other object with a fluoresce property, exists within the waste detection zone, then the waste alert component may detect an increase in light due to the waste object fluorescing visible light in response to the ultraviolet light. If the increase in light intensity exceeds a detection threshold, then the waste alert component may provide a waste detection alert that the waste object exists within the waste detection zone (e.g., a message may be sent to a housekeeper that paper towel waste in on the bathroom countertop).
