Below is a list of Hazardous Waste Containers manufacturers from Romulus, Michigan. Hazardous waste containers are portable devices used to store, transport and in other ways handle waste materials that are harmful to people and/or the environment. As a method of spill containment, hazardous waste containers enable proper material handling of waste as specified by the Environmental Protection Agency (EPA). While a wide range of containers such as railroad cars, test tubes and tanker trucks are used to handle waste, 55 gallon drums are the most common type of hazardous waste container.
