The Paper Processing

In some countries, waste paper is recycled to
make better quality paper.
After collecting paper, the paper puts in the
machine to remove paper clips; plastic and
staples.
Next, it sorts into categories e.g newspaper,
computer paper and magazines.
Then remove ink by:
a) soaking paper and breaking up into pulp in
huge washers,
b) adding chemicals.
Other materials maybe added to pulp e.g bleaches,
dyes and chemicals. After that pass through
heavy roller to squeeze out water.
Next, press and flatten into thin sheets.
Dry in furnaces
Polish and treat final product.
Subsequently, it cut into sheets or rolls.
Finally, packaging product for distribution
to customer.
