Description of the life cycle phases
2.1. Manufacture (A1, A2 and A3)
Raw materials (A1 and A2)
The
porcelain
stoneware tile
product (BIa)
basically
consists
of clay, sand
and
feldspar with a glaze layer mainly consisting of feldspar, carbonate, silicate and
kaolin, among other materials.
The
raw
materials
used
come
from
different
origins
(local,
national,
Turkey,
Ukraine, Italy or the United Kingdom).
This variation is due to the impossibility
of obtaining these
raw
materials
from a
single source.
The
raw
materials from
outside of
Spain
are transported
by freighter to
the port of Castellón
and
from
there
by
truck
to
the
plant
for
manufacturing
the
spray-dried
powder.
For
marine transport, a transoceanic freighter is used, whose transportation distance
varies in each case depending on the point of origin.
The raw clay materials are
transported in bulk, meaning packaging materials are not required.
The frits are
transported in bigbags on pallets.
Manufacturing (A3)
The
industrial
process
at
the
GRESPANIA
plant
in
Castellón
starts
with
the
reception of the spray-dried clay in metal hoppers ready to receive the clay from
the
transportation
trucks.
The
clay
is
then
transported
to
the
corresponding
storage silos on unloading and conveyor belts.
The
clay
is
then
transported
to
the
presses
using
conveyor
belts,
where
if
necessary
it
can
be
treated
in
a
technological
tower
or
a
colouring
system
to
create specific types of effects.
