you grind the paper into small pcs. electrical energy is used to power the grinders. Gas or propane is used to move the bails of paper out side of your building and electrical power is used for fort lifts inside the plant.

moving the paper from the grinder to the bleacher is conveyor belts. electrical power again.

bleaching of the paper will take out most of the color and leave you with a gunky mess of ink and fine paper, this isn’t usable waste.

To the dryers next, again in tubs and a fork lift. pour it out and press it down into form and extrude it into the thickness you want and the pattern on the paper you need. i.e. a paper napkin that is a lite brown in color and used to clean up after eating fast food.

so your waste is anything that is not made into paper that comes in with your paper. string, wire, etc. fuels and electrical power. Any water used will be contaminated so it has to be put into a holding pond and then pumped out again to drain and to the sewer system a After it is stirred and cleaned up.
