Mars

Sustainability makes Mars’ chocolate even better

The challenge

Mars strives to have a complete sustainable production in the year 2040 via its Sustainable In one Generation Plan. Through the installation of  Memthane®, a membrane bioreactor for biological treatment of heavily contaminated wastewater, Mars makes significant progress towards its sustainability targets at its largest chocolate processing facility in the world.


Veolia’s solution

Our experts supplied the most appropriate anaerobic wastewater treatment technology to maximize renewable energy production while producing high-quality effluent. The solution differentiates by achieving more than 99% removal in a one stage anaerobic process. In the memthane reactor the wastewater from Mars is biologically treated and converted into high calorific biogas. The treated effluent and biomass are separated by means of ultra filtration units. The biomass is then returned to the reactor. The final effluent discharged to sewer.

The team ensures the  maintenance of the wastewater treatment plant.
