Recycling is a good thing for us environmentally. During war, recycling also shoulders the imperative of patriotism.
During World War II, scrap drives were common and, by most measures, successful in providing more materials, including metals, for war use.
Jan McKee of the Library of Congress (LOC) points out that World War II scrap drives inadvertently destroyed many metal master recordings, since recording companies did not think that the popular music was worth keeping. The exceptions are archival treasures now. Read McKee’s post at the LOC site here: Scrap for Victory! | Now See Hear!.
