Esabel<br />

In 2011, Esabel was started up at 10 <strong>Group</strong><br />

<strong>site</strong>s. <strong>The</strong> three-year reduction targets<br />

look very promising. One concrete<br />

example of potential savings is an<br />

initiative to replace the vacuum pump<br />

model used in the packaging stage of the<br />

production chain. <strong>The</strong> new pump, which<br />

is 60% more energy efficient, will be<br />

deployed at all <strong>Group</strong> <strong>site</strong>s producing<br />

<strong>The</strong> Laughing Cow ® cheese. <strong>The</strong> new<br />

model pump is already operating at<br />

six <strong>Group</strong> plants. In 2012, it will be<br />

deployed at plants in Ulzama, Spain,<br />

Tangier, Morocco and Lons-le-Saunier,<br />

France.<br />

A key criterion for equipping plants<br />

Environmental friendliness is a<br />

fundamental part of the equation when<br />

replacing equipment, installing new<br />

production lines or building new plants.<br />

That principle was clearly applied when<br />

the <strong>Group</strong> opened a plant in Vietnam in<br />

2011. Lower water usage was integrated<br />

at the design stage of the project, and a<br />

biological wastewater treatment plant<br />

was also installed. Another project,<br />

a new Mini Babybel ® plant, will be<br />

operational in 2014, in the United States.<br />

<strong>The</strong> team in charge is seeking to make<br />

the new plant a model under the LEED<br />

(Leadership in Energy and<br />

Environmental Design) rating system<br />

for green buildings.<br />

interview<br />

New Vietnam plant opts<br />

for a biological wastewater<br />

treatment facility<br />

FRANÇOIS PONS, <strong>Bel</strong> Vietnam plant Director<br />

Under what conditions<br />

was the biological<br />

wastewater treatment<br />

plant launched?<br />

Environmental standards are<br />

very stringent in Vietnam, particularly for<br />

effl uents and treatment. To treat<br />

wastewater from the My Phuoc 3 plant<br />

inaugurated at end 2011, we opted for a<br />

biological treatment facility with vertical<br />

closed-loop reactors, in which organic<br />

matter is broken down by microorganisms<br />

niched inside millions of polystyrene<br />

beads. <strong>The</strong> water to be treated percolates<br />

by gravity around these beads, and air is<br />

blown against the current to maintain<br />

aerobic conditions. This ecological and<br />

economical system is a fi rst for the <strong>Group</strong>.<br />

What are the results so far?<br />

<strong>The</strong> plant has been producing since July<br />

2011. While the selection of the treatment<br />

facility was a bit of a gamble, it has proven<br />

to be an astute move, because the results<br />

are even better than expected. One of the<br />

main criteria is the amount of Chemical<br />

Oxygen Demand (COD). <strong>The</strong> maximum<br />

standard allowed is 100 milligrams per liter.<br />

Our discharges range from 15 milligrams<br />

to 30 milligrams per liter. In addition,<br />

the treatment facility consumes very little<br />

power.<br />

How does this project tie into the<br />

<strong>Group</strong>’s overall environmental<br />

policy?<br />

Beyond the biological process, which is<br />

particularly environmentally friendly, we<br />

have also set reduction targets for water<br />

consumption and effl uents discharged<br />

into the public sewer system. After<br />

six months of operation and a progressive<br />

ramping up of activity, we currently use<br />

six cubic meters of water and discharge<br />

4.5 cubic meters of wastewater per metric<br />

ton of cheese produced. We are working<br />

on solutions to reach maximum water<br />

consumption of four cubic meters and<br />

three cubic meters of wastewater per<br />

metric ton of cheese produced.<br />

<strong>The</strong> savings will have a direct impact<br />

on our water usage, as well as our<br />

wastewater treatment costs.<br />
