To make your own mod compatible with the Production Scrap 2 mod, just use one or both of the following functions:

scraplib.addScrap(recipe, scrapType, scrapProbability, scrapAmount)
Ex: scraplib.addScrap("iron-plate", "iron-plate-scrap", 0.06, 1)

• recipe: This is simply the recipe name for the item you are creating scrap for.
• scrapType: (see below for the current list of scrap types available)
• scrapProbability: A number between 0 and 1; you may use any number you wish. The default number used in
  Production Scrap 2 is 0.06
• scrapAmount: The number of pieces of scrap produced with each cycle.

scraplib.addFurnaceResult(furnace, amount)
Ex: scraplib.addFurnaceResult("electric-furnace", 2)

• furnace: The name of the new type of furnace your mod uses (vanilla furnaces are covered in Production Scrap 2)
• amount: This represents the field "result_inventory_size". Basically, the number of output items for your furnace.
