This simple mod changes the game in a big way- you are forced to reckon with waste. Most recipes will now produce additional useless Scrap which you must filter out and either burn, discard or sequester. Scrap has no use and cannot be burned for fuel. Because every single recipe is affected, the scale of the waste is enormous and it's polluting effects will quickly become a problem.
When starting from scratch, you might want to rush the logistics research that adds filter inserters.
