I have been using the "search function" everyway I can think of to find a definition for "shred".

Some posts it seems to be small miscellaneous steel. Other times it seems to be just about anything metal you can sweep off the floor. Then I saw someone mention that after pulling anything of value off, they put their brown low grade e waste in with their shred. Does this really work? Selling fiber board as metal? Now I am back to confused as to what "shred" is.
