VINCI 2005 ANNUAL REPORT
the sustainable development competition
organised by UNPG, the French national
union of aggregate producers, for their use
of household waste incineration bottom ash
in the construction of an interchange on the
A15 motorway in the Val d’Oise region (see
p. 134).
ALTERNATIVE
PROCESSES
Eurovia has continued to develop processes
that reduce the consumption of materials in
road building. Recyclovia ® , for instance, is
a cold in situ recycling process launched in
2005 for repairing the road surface. Another
new process, Polybitume C, optimises the
recycling of used tyres and improves the
properties of asphalt containing this material,
which can be laid at the same temperature
as pure asphalt. Developed by Eurovia’s
Spanish subsidiary, Probisa, this process
won a special sustainable development
award in the VINCI 2005 Innovation Awards
Competition.
Eurovia and VINCI Construction subsidiaries
specialising in demolition and deconstruction
continue to develop solutions that optimise
the rate of materials reuse.
Reducing energy
consumption
In 2005, VINCI companies continued their
efforts to reduce energy consumption. This
priority area for improvement, common
to all of them, is implemented through a
number of different programmes.
ELECTRICITY
CONSUMPTION
Initiatives designed to limit energy consumption
on worksites included “Home
vert”, a new type of site hut developed and
tested in 2005 by GTM Construction in
partnership with ADEME, France’s environment
and energy management agency. The
stakes are high: heating and air-conditioning
the company’s 3,000 huts accounts for 60%
of electricity consumption on its sites, i.e.
estimated annual production of 5,300 tonnes
of greenhouse gases. The installation of a
building automation system, together with
better heat insulation to reduce the number
of thermal bridges, saves 3,000 kWh a year
per site accommodation complex.
WARM MIX ASPHALTS
TO SAVE ENERGY
One of the main areas of Eurovia’s research
and development programme is reducing
the temperature to which aggregates have to
be heated for road surfacing. The company’s
Aspha-Min ® process brings the asphalt
mix production temperature down 30°C
and reduces energy consumption by 20%.
It won the FNTP (French public works
federation) innovation award in May 2005,
and the grand prize for innovation at the
trade fair for French mayors and municipalities
in November.
FUEL CONSUMPTION
Greenhouse gas emissions associated with
VINCI’s business activities are attributable
mainly to its fl eet of 30,000 service vehicles
and 5,000 site vehicles. As part of the
Group’s purchasing policy, buyer training
and awareness raising initiatives, combined
with the programme to reduce the risk of
road accidents, have led to action being
taken on a number of fronts. These include
controlling fuel consumption, detecting
potential malfunctions in engines, preventing
dangerous driving habits, and the achievement
of considerable savings. In 2005, VINCI
set 2.5% as the target for reducing vehiclerelated
greenhouse gas emissions. Numerous
initiatives have been taken at business unit
level.
At Roissy-Charles de Gaulle, half of the
vehicles operated by EFS-WFS, the VINCI
Concessions airport services subsidiary, run
on electricity. The company has also launched
a carbon assessment scheme with Aéroports
de Paris and ADEME (France’s environment
and energy management agency). At
VINCI Energies, several business units have
acquired dual energy (internal combustion
and electricity) mobile inspection platforms,
and German business units decided to buy
service vehicles fi tted with particulate fi lters.
In Africa, Sogea-Satom continued its vehicle
replacement programme and reached its
intermediate target: 45% of all vehicles are
now compliant with European fuel consumption
standards.
