Describe the Suggestion

Add sawdust as a byproduct of recipes crafted with the mechanical saw (25-50% chance), getting placed like Immersive Engineering sawdust.
In the best case, this could even have custom recipes so that you can edit the byproduct of certain recipes for a modpack, the sawdust sheet on the ground dropping the item specified by the recipe.

Sawdust could be used to make particle board which could fill in for planks in recipes (4 sawdust in 2x2 for one particle board) or compressed into a block (3x3 like a material storage block) for furnace fuel better than regular planks but not nearly as good as coal (three items is a good amount for 9 sawdust Imo.)

Another good use for sawdust could be in a mixer with water and lime dye as a sidegrade slimeball recipe to the existing dough and dye recipe for factories that have a large sawmill setup.

A small addition

Another nice thing would be for a compatibility addition to add tree bark from Farmers Delight as a drop from the log > plank recipe.
