During World War II, Americans took part in large-scale recycling efforts to support the war. They were encouraged to collect materials like tin cans, rubber, waste paper, nylon (for parachutes), scrap metal, and even fats from cooking for explosives. Nationwide scrap metal drives were organized, with farmers urged by John Deere to “Sink a Sub From Your Farm” by contributing scrap. Clothing was collected for cleaning machinery and navy ship decks, and many other materials were salvaged to support the war effort.
For older generations, this was familiar, as they had just emerged from the Great Depression when supplies were scarce. For younger Americans, however, this scarcity was new and difficult. They learned to cope by conserving resources, eating leftovers, recycling, growing vegetables, and canning them for later use. Gasoline was rationed, and the national speed limit was reduced to 35 mph to save fuel.
War propaganda played a major role in encouraging civilian sacrifice, particularly targeting women. Posters urged them to conserve resources, with some calling them to enlist or support the war through household conservation efforts. A government campaign emphasized, “Not to share in sacrifices for Victory was an unpatriotic act.” Rationing helped combat price-fixing and black marketing, making sure everyone shared in the shortages equally.
Junk rallies were held in communities, with children even going door-to-door with red wagons to collect scrap metal. Signs for these rallies read: “Don’t let brave men die because we faltered at home. Pile the scrap metal on your parkway. Civilian Defense workers will pick it up. Junk helps make guns, tanks, ships for our fighting men...” These efforts were critical to the war production effort and became a symbol of the shared sacrifice needed for victory.
