Read the passage carefully. Then choose the
correct answer. |
|
|
Old newspapers, magazines and other unwanted
papers are collected
by the rag-and-bone man. The recovered paper
is then sorted according to
the grade or type of paper before being sent to
the recycling centre. There,
the sorted papers are gathered and bundled into
tight bales before they are
transported to a paper manufacturing factory
where they will be recycled
into new paper. Only paper free of contaminants
such as food, plastic, metal
and other rubbish can be successfully recycled;
otherwise, impurities and
bacteria might be introduced into the recycling
process and thereby affect
the quality of the paper produced.At the
paper mill, recovered paper is chopped up and
mixed with water
to form pulp slurry, which is then subjected to
a series of washing where
soap-like chemicals called surfactants remove
ink from the paper. After the
deinking process, the pulp slurry is sprayed
onto a huge flat wire screen
that is rapidly moving through the paper
machine. Water drains out and
fibres bond together into a web of paper which
is pressed between rollers
to squeeze out more water and smoothen the
surface. Heated rollers dry the
paper, which is then slit into smaller rolls or
sheets and finally removed from
the paper machine.
Papermaking fibres can be typically recycled
five to seven times before
they become too short and are rejected by the
paper machine. Recycling
paper certainly benefits the environment because
it requires at least
50 per cent less energy and up to 75 per cent
less water than making paper
from virgin fibres. Also, it reduces the demand
for virgin fibre in the world.
So, have you done your part to save Mother
Earth?

What happens to papermaking fibers as a result of repeated recycling ? |
| |
|
|
|
