Many/most players by now know that each settlement location has a limit of just how many objects may be placed before the the settlement size bar maxes out. Many/most probably also already know that scrapping items will reduce the item total, allowing for additional items to be placed. Bringing items into a settlement and scrapping them there effectively increases that settlement's item budget. BUT DID YOU KNOW that you can scrap raw resources (the stuff that other objects break down to)? Acid, Antiseptic, Copper, Steel, Wood, etc., et al can also be scrapped and what you get is a 1-for-1 breakdown: E.G., 100 Wood scrap down to 100 Wood. And you can scrap raw resources an endless number of times. It is entirely possible to have a completely full settle bar be completely emptied out, simply by scrapping the same raw resources over and over again.
