All our fleet vehicles are VOLVO and SCANIA; they are equipped with engines that meet EURO 5 or EURO 6 standards.
The continuous renewal of vehicles, a policy in place for several years, results in less and less polluting transport and costs controlled by lower fuel consumption.
In addition, this policy gives the company economic strength and the ability to benefit permanently from modern, reliable and efficient vehicles and equipment.
The European emission standards, known as EURO standards, are European Union regulations setting maximum limits of pollutants for all types of vehicles. Their goal is to reduce air pollution caused by road transport.
This is therefore a set of increasingly restrictive standards applying to new vehicles.
For trucks, EURO 5, applicable since 1st October 2009, has achieved in late 2013, just before the entry into force of the new EURO 6 standard, a decrease of around 80% of all emissions.
The EURO 6 standard, applicable since 1st January 2014, represents a major new challenge for truck manufacturers: to divide by five the emissions of nitrogen oxides, by almost four those of unburned hydrocarbons, and by two those of fine particulates. Regarding these particulates, a drastic decrease was announced, halving their mass, and also dividing their number by six.
In addition to this reduction of pollution limits, the EURO 6 added new scales of measurement, with cold start and restart. It also toughened considerably the required criteria over time: the new pollution limits must be respected for 7 years or 700,000 km.
To meet these new constraints, manufacturers have deployed a wide range of technologies. Most of the time, the EURO 6 standard devotes itself to the generalisation of the particulates filter, and very often to the closed type and to regeneration by auto controlled combustion. But for some manufacturers, the changeover to the EURO 6 has been a time of radical choices such as the abandonment of the exhaust gas recirculation (EGR) system, source of many malfunctions.
To this spectacular progress on emissions one should add the tangible and continuing decline in fuel consumption. This improvement in performance which runs from 2 to 5%, depending on the manufacturer, nevertheless has a cost. This is estimated between 6,000 and € 10,000 for the purchase of a tractor.
The use of AdBlue was also generalised to satisfy the EURO 5 standard that this system achieves. Thus, almost all European manufacturers of heavy trucks (lorries or buses) now offer SCR (Selective Catalytic Reduction) vehicles.

All our parking and washing / disinfection areas are equipped with hydrocarbon separators in order to preserve the environment.
These facilities comply with standards EN 858-1 and EN 858-2 and are the subject of a periodic maintenance plan.
Hydrocarbons separators are devices for trapping, by gravity and / or coalescence hydrocarbons present in rainwater. The law on water and aquatic environments requires their implementation into service stations, parking lots, car washes, etc., whose surfaces are susceptible to receiving significant quantities of hydrocarbons. They are then sited upstream of the connection to the public drainage network. The DIN 1999 standard limits the residual hydrocarbon content of the discharged water to 5mg / L.
The scrubber performs a first separation of the heavier matter (sand, sludge) that settles to the bottom of the tank.
The coalescing filter delivers better purification output: water passes from the bottom to the top, thus promoting the floatation of hydrocarbons. The particles of oil in suspension in the water stick to the back of the blades and form an oil film which migrates from the bottom upwards.
In the separator, hydrocarbons with a density of 0.85 rise to the surface.
The automatic obturator prevents releases into the natural environment: the float of the shutter, calibrated to a 0.85 density, floats in water but sinks in oil.
The separating output of hydrocarbon separators complying with the EN 858-1 standard is at least above or equal to 99.88%.
