Process of waste paper recycling
Scrap recycling station
Waste paper collectors collected the waste paper and sold it to the waste collection station. The waste collection station will classify and package different waste papers according to their material prices, etc. The packaged waste paper will be sold to paper and pulp mills.
Pulp making section of paper mill
The process of waste paper pulping is crushing, screening, deinking, rinsing, pulp purification, refining, etc.
It’s just that the raw materials of waste paper are mixed. Some waste boxes have staples, some waste paper has a plastic film layer, and some have glue and ink.
These impurities are removed during the pulping process based on their characteristics. Large pieces of impurities are separated by the pulper screen plate. The heavy sand iron nails are removed by the descaler, the ink is dispersed by the deinking agent and floats, the adhesive is removed by the light slag table, and the small particles that have not been removed are heated and dispersed into small particles under the action of chemical substances, then they are dsorbed by fibers.
After a series of screening and purification, waste paper is transformed from domestic waste such as cardboard boxes and magazines into paper pulp.
Paper machine
Waste paper raw materials are often recycled multiple times and their quality is unstable. Therefore, paper machine pulps waste paper pulp and mixes it with raw fibers to produce high-quality paper.
To learn more about the production process of paper, you can read our guide how is made paper.
Paper processing factory
Processing plants will purchase raw paper for processing based on the end use. These papers will be processed into cartons and packaging for daily use through different processing methods, such as printing, coating, film coating, hot stamping, die cutting, box gluing, etc.
That is the process of waste paper recycling. Using waste paper as raw material for papermaking, the pulp yield is about 75%-85%.
