The Process of
Paper Recycling
Some environmentally
conscious individuals may wonder how the process of paper
recycling works. This material has many uses and it can be
reused a number of times. Following is a brief outline of how
the paper recycling process works.
The consumer discards various
paper products, sending them to the nearest recycling center.
The waste is made into new paper products through a system of
steps.
There are different types of
paper so some of the details differ in the process. However,
the fundamental strategy is the same for each type. The three
types of paper include:
• Pre-consumer waste – This
form of paper was never used.
• Post-consumer waste – This form was used by an individual.
Some refer to this type as scrap paper.
• Mill broke – Is simply scrap left over in the production of
paper. This material can easily be reused in a paper mill. It
is not recycled at a paper recycling facility.
The paper recycling process
begins with water. Pulping is the act of adding water to the
material in order to separate its strands. The fibers left
behind are called pulp.
The pulp is put on a screen
that works like a colander. Larger particles are left behind in
the process. After the pulp is screened, it is cleaned through
a process called centrifugal cleaning.
A machine spins the pulp
rapidly. This makes any other contaminants left behind during
the screening process to separate from the mixture.
Many paper products have ink
in them. Deinking involves putting air bubbles into the pulp
along with a chemical. The chemical separates the ink from the
pulp and the bubbles force the ink to the surface.
The machine kneads the pulp.
Next, the mixture is washed with water to remove any remaining
containments. The pulp may or may not be bleached in the paper
recycling process.
The pulp is the prime
ingredient in the new paper created. The new product is white
if the paper recycling process included a bleaching stage.
Otherwise, it has some dull color to it.
The final steps in the
process of paper recycling involve cleaning the workspace. The
water that was used to remove the ink and other containments
can be filtered for reuse. Some of the water can not be used
again and has to be discarded.
Paper recycling is a simple
process that yields great results. Consumers who take time in
making sure that their paper products are free of containments
help to make the process run smoother. It only takes a few
minutes to recycle paper products. It is well worth the
effort.
