About this mod:

This is a simple modification that adds up to two by-products to the intermediate products:
The scrap metal probability is 10% by default (can be changed in the startup settings) for one scrap metal type, this value is divided by the amount of scrap metal types in a recipe. (example: iron gear wheel: 10% for iron scrap metal, low density structure: 5% for copper and 5% for steel scrap metal) This scrap metal can be collected and later processed in a recycler and then smelted into plates.

It's very simple, but it adds a small layer of complexity to your transport-belt layout. In the early game you can easily solve this with splitters or filter-inserters. Later in high-production areas, you have a dedicated transport-belt for this purpose.

This mod supports all Bob and Angel metals if you had one or both of them.
