In 2011, the total volume of industrial effluents fell by
15% year on year in absolute terms and by 25% relative
to sales.
This decrease is related to that in water consumption resulting
from various process-optimization initiatives across Group
sites.
Valeo’s sites measure the degree of pollution contained in
their effluents by reference to various indicators, including the
content of heavy metals, COD (chemical oxygen demand),
BOD (biological oxygen demand) and the presence of
suspended material (SM). Precision and transparency are
central to the Group’s targeted reduction in effluents. This
is evidenced by the public display of monthly information
concerning effluent volume, other emissions and resource
consumption at the entrance to the Pune plant in India.
In 2011, heavy metal content in effluents dropped by 72%
in absolute terms. This steep reduction is due mainly to
the resolution of a technical problem affecting the effluent
filtration system at the Rayong plant in Thailand, which was
the principal contributor to the indicator in 2010.
Reduction of atmospheric emissions
and of ozone-depleting substances
Valeo also monitors atmospheric emissions resulting from its
operations by measuring the presence of ozone-depleting
substances (ODS), emissions of lead to the atmosphere, TCE
(trichloroethylene) and VOCs (volatile organic compounds).
2012 will see the introduction of an “Ozone-depleting
substances” Directive, which will explain which substances
are concerned, how they are used in manufacturing and the
timetable for their withdrawal.
Despite a steep downward trend since 2007, emissions of
lead and TCE rose slightly in 2011 as a result of the first-time
100% consolidation of data concerning the Taegu plant in
South Korea, which is chiefly responsible for such emissions.
But for that change, TCE emissions would have fallen by
12% in 2011.
The increase in lead emissions is attributable to two plants,
Annemasse in France and Veszprém in Hungary, which are
now the only Group sites to perform lead welding following
the discontinuation of all lead-welding operations by the
Shenzen plant in China during the year.

As a proportion of sales, VOCs were down by 2%
over 2011. The year saw significant efforts to make VOC
measurement more reliable by improving the evaluation tool
used at certain sites, including the Sens plant in France and
the Skawina plant in Poland, which has since refined its
data capture. The enhancement of VOC measurement will
continue in 2012.
