The Utter Scrap is a crushed soda can that is the second treasure found in Pikmin 2. It is in the Valley of Repose and its location is blocked by a bag which requires 35 Pikmin to deflate. Once that's is taken care of, defeat the small Bulborb and the larger one sleeping in the arena. Collect the treasure and the Bulborb bodies if you have any Pikmin left over.
