This document discusses the process of making paper pulp from waste paper for industrial and commercial purposes. It involves collecting waste paper, shredding it, soaking it in water, and using a hydropulper to break it down into a pulp. The pulp can then be stored, pressed to remove water, calendared, cut, and dried to make new paper products like paper bags, folders, and notebooks. The pulp can also be used to directly make building models, egg trays, or crafts using molds. The process helps reduce deforestation and pollution compared to using fresh paper.
