Back to sectors
Industries now need to rise to a combination of major environmental, regulatory, social, economic and operational challenges. As a result, they have begun to look beyond simple service solutions in search of a truly creative partner able to innovate. This is the kind of ongoing challenge at which Veolia excels.

Mars turns its wastewater into clean energy

Veolia is working with Mars to reduce its water and carbon footprints.


The Mars plant in Veghel is the world's largest chocolate factory, producing Mars, Snickers, Milky Way, Bounty and Twix chocolate bars for the European market. As part of its campaign to reduce the use of fossil fuels and mitigate its impact on the environment, Mars chose to implement an outstanding wastewater treatment and recovery facility at the Veghel plant.


Veolia's solution involved building and operating a wastewater treatment facility equipped with patented Memthane technology, which can turn 98% of organic pollution into a source of clean energy (biogas), cutting the Veghel plant’s energy bill by 10%.
