How to get in the game scrap (trash) (Gears 5)

People tell me how to get the game a scrap, in GOW 4, it was possible to disassemble unwanted cards and skins and then craft what you need, but in this game I have not found, despite the fact that there are things that can be crafted. Played in multiplayer 20 hours but scrap and appeared near the icon is number 0
PS not to be confused with the iron to make iron in the game I know but this is different
