The Process of Paper Recycling

9:33 pm Houston, Paper recycling


The process of paper recycling involves the recovery of waste paper and remaking the same into new kinds of paper products. There are 3 main categories of paper which are used as the feed stocks for recycling paper. These are the pre-consumer waste, mill broke and the post consumer waste. The pre-consumer waste is the material which has been discarded even before the consumer had used it. The mill broke is the paper which is basically the trimmings of paper and other similar kinds of paper scraps which are leftover from the manufacturing of paper. The post consumer paper is the paper which is waste material that has been discarded after the use of the consumer. These include the old magazines, the old telephone directories, various kinds of residential mixed paper and other forms of paper. All paper which is suitable for recycling is known as scrap paper.


The process of paper recycling involves various stages. These also depend on the specific type of paper that has to be recycled. These include the mixed office waste, corrugated fiberboard, newspaper and other forms of paper. There are various steps in recycling paper. The first step for paper recycling is the process of pulping. Through this process water is added and applied to the mechanical action of papers so that the fibers can be separated from each other. Then is the process of screening where the screens are used with slots or holes so that the contaminants from the larger pulp fibers can be removed. After this is the process of centrifugal cleaning. Here the spinning the pulp in a cleanser helps the materials to become denser than the pulp fibers. This facilitates their moving outward and being rejected.


Through flotation the air bubbles are passed through pulp slurry. The same has a surfactant present which also causes the ink particles to collect along with the foam on the surface. Removing these also helps the pulp to become brighter. There are sometimes steps called de-inking which are included in this process. The kneading or the dispersion process involves mechanical action being applied to the contaminant particles. The small particles of the paper are then removed by passing water through the pulp. In case where white paper is required, bleaching through peroxides or hydrosulfites is done to remove color from the pulp. Then the new paper is made in the same way like the virgin paper. After this the process of dissolved air flotation and waste disposal is done.
