Study of Making Advanced Corrugated Paper from Mixing Paper Sludge with Leather Wastes

There was a certain amount of fibers in paper sludge, including the short fiber and small fiber. Collagen fiber was a compound with high bond energy, which can be reused from the leather solid waste, and contained many polar groups. Both fibers can be well combined with Hydrogen bond. So the collagen fiber and paper sludge were studied as raw materials, mixed with plant fiber, to make corrugated paper. The results showed that, when the wastes were used to make the corrugated paper, its central pressure indicators could reach its national standard.
