Energy
The power consumption of the division rose 97%. The increase was attri-
butableexclusivelytotheinclusioninthereportingscopeofLesTanneries
du Puy, which accounted for half of the division’s energy consumption.
The average ratio of energy consumption to revenue was stable on the
scope of exotic tanneries and the Annonay tannery. However, there was
a slight increase on two exotic leather tanneries (Montereau and Vivoin)
due to the expansion of machinery fleets, new buildings and improve-
ments to capture and ventilation systems on work premises.

Water
The Silk division’s water consumption was down 16% compared
with 2015. Several measures were taken on the various sites to obtain
this outcome: replacement of obsolete machinery, optimisation of pro-
cesses, detailed monitoring of consumption by area, etc. Water mana-
gement of facilities has become a concern shared by all workshops. At
SIEGL, a water recycling process
via
the lagoon contributes significantly
to the improved results.
Energy
Despite a colder winter than in 2015 and an increase in business, the
subsidiary’s energy consumption was virtually stable (+1%).

Water
Water consumption fell sharply in 2016 (-9% compared with 2015).
Several events combine to explain this outcome: the interruption of the
melting process during site development work in the workshop and the
construction of the tank furnace, meaning that work was reduced to two
workstations rather than three. The shutdown of the previous tank fur-
nace, whose water consumption had increased significantly at the end
of the season, was another factor in the saving.
Energy
Overall energy consumption was comparable with that of 2015.
Electricity consumption decreased slightly, mainly following the decom-
missioning of the former tank furnace inOctober 2016. The shareof elec-
tricity consumptionattributable to the new furnace is less than that of the
previous one. The efficiency of natural gas facilities installed in2014and
2015 (pot furnace, centralised heating, etc.) was confirmed this year.
The gradual replacement of openings by new equipment will contribute
to tighter control of gas consumption.

that back-up radiators were used during the first two months of 2015.
The replacement of the fleet of forklifts by electric models in 2016 also
contributed to the reduction.
Textiles
2016 was marked by a sharp increase in production volumes in the second half of the year. Revenue was up 3.1% over the full year compared
with 2015. Despite this growth, total energy consumption was broadly stable, and water consumption showed a pronounced improvement.
Crystal
The production unit’s 2016 business volumes were stable in value, with improved performance ratios in terms of production volumes, despite the
interruption of the melting process during the construction of a new tank furnace.
