Water
The Nontron site uses water in its manufacturing process for the deco-
ration of porcelain and, to a lesser extent, for the enamel activity. Overall
water consumption increased by less than 1% year on year in 2016. This
small increase resulted from stronger activity in the workshops. It was
kept low by the various action plans undertaken:
s
s
installation of tray reducers that can be inserted into the dipping
tanks of new decoration workstations: the height of the dipping water
is unchanged, but the surface is cut by between 40% and 50%;
s
s
installation of a circulation pump to supply hot water for new decora-
tionworkstations: thewaiting time before the arrival of sufficiently hot
water at the workstation has been reduced;
s
s
installation of a pressure reducer at the headend to reduce the risk
of leaks.
Energy
The site’s energy consumption was up 4% compared with 2016. The
increase is attributable to the consumption of electricity by the porcelain
kiln. To deal with an increase of the firing time of decorations, the kiln
utilisation time was extended by more than 10%. This increase stems
fromproduction volumes but also the product firing time, as new designs
require longer in the kiln.
Measures have been taken to reduce energy consumption, such as:
s
s
the removal of halogen lights and the installation of LED systems on
the last of the decoration workshop workstations as well as on all
brush workshop workstations;
s
s
but also, as the programming of compressors provides for their shut-
down in the evening and on the weekend, louvres have been installed
on porcelain and decoration kilnworkshop sheds to allow these areas
to cool naturally.

Water
Water is primarily used for domestic purposes to supply the automa-
tic fire suppression network and for the washing and development of
frames. Water consumption was stable in 2016 after a sharp decline
in 2015 (-31%) following the shutdown of a cooling tower, replaced by a
new refrigeration unit.
Energy
Electricity is mainly used for air conditioning, which is necessary to
control the humidity and temperature of the workshops. Its consumption
is stable. The new refrigeration unit is the main cause of the increased
gas consumption.
