Метод «світлофора» як інструмент оцінювання ефективності управління відходами в залізничному цеху

The study investigates the application of the “traffic light method” as a practical instrument of internal environmental auditing for assessing the effectiveness of waste management at industrial production sites. The approach is based on a system of evaluation indicators adapted to the operational characteristics of specific structural units, particularly railway workshops. The proposed method is consistent with the requirements of ISO 14001 Environmental Management Systems and follows the principles of the Plan–Do– Check–Act cycle, which provides a framework for the continuous improvement of environmental management processes.
