Any Workbench allowing to craft new items (food,chemistry) offers you a new recipe, once crafted close the crafting menu to enter the scrap menu.
The menu is actually a Container, place any scrap you want to dismantle inside it and close the menu, after a second you get their components.

Known Issues:
A small part of the scrap isn't dismantled in the first iteration, (especially if you place enormous amounts of scrap into the container,) just dis mantle them again.(fixed 1.1)


Used tools:
