Packaging firm DS Smith has invested €7.5 million in expanding the anaerobic treatment facility at its paper mill in northern France.
The investment enables Rouen Paper Mill to generate green energy from 100% of its wastewater and improve the quality of discharged water – building the circular economy and taking another step towards DS Smith’s carbon goals.
The process generates biogas that is converted into sustainable energy by the mill’s partner, IDEX. This is then used to provide green electricity to homes and businesses in the Normandy region.
The expansion is expected to boost the mill’s total biogas production from 26,000 MWh to 39,000 MWh annually – delivering potential savings of up to 2,600 tonnes of CO2 annually – equivalent to taking over 600 small cars off the road every year.
“We are very proud to have increased our green energy credentials with the expansion of our wastewater treatment facilities at Rouen Paper Mill,” said Bruno Steh, cluster energy coordinator for DS Smith.
“We are not only treating the wastewater onsite but extracting a naturally produced resource which is converted into green electricity. This investment was a key driver in our overall strategy to reduce the impact of our operations here in France and contribute to providing green power to the region.”
