Creation of a sustainable wastewater treatment plant

The challenge

Mars strives to have a complete sustainable production in the year 2040 (Sustainable In one Generation program). Through the installation of the anaerobic Memthane® treatment plant in Veghel (The Netherlands), Mars makes significant progress in the achievement of its sustainability targets at their largest chocolate processing facility in the world.


Veolia’s solution

VWT will supply the most appropriate anaerobic wastewater treatment technology. 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 returned to the reactor and the final effluent is discharged to the sewer system. Complete operation and maintenance of the wastewater treatment plant is also planned.


Benefits for Mars

  • Most compact solution and lowest operational costs in comparison to other treatment routes
  • Net carbon footprint reduction of more than 150 Ton CO₂/year
  • Maximization of renewable energy production, up to 10% of gas consumption
  • More than 99% reduction of pollution equivalents
  • Complete outsourcing of operations
Mars figures
Today, the Mars family of Associates is 80,000 strong in 78 countries around the world. Mars makes a lot more than just chocolate. Mars has six distinct and different businesses - Petcare, Chocolate, Wrigley, Food, Drinks and Symbioscience - which have helped the company reach billions of consumers and achieve more than $33 billion in global sales. From selling PEDIGREE® dog food in New Zealand to planting SEEDS OF CHANGE® in South Africa, Mars reaches out to nearly every corner of the globe.
