Paper-mills produce paper of various quality, from equally various base
materials.
The main base material of paper-making is vegetable fibre. Fibres can be
obtained from coniferous trees (spruce, fir), frondiferous trees (poplar, aspen,
birch), cereals, etc.
Nowadays, for economic and environment protection reasons, waste paper
collecting is playing a bigger and bigger role.
We can prevent the huge amount of superfluous paper from becoming litter with a
little care and attention … with selective collecting.
The waste paper produced in institutions, schools, and households is of many
kinds, but the fundamental condition of its utilization is pureness.
