Turning waste into valuable resources is a key challenge in building a more sustainable industrial sector. At NSE, this ambition is reflected in the practical initiatives implemented every day to continuously improve the management and recovery of waste generated by our operations.
At the Abrest site, this approach has been supported for several years by a close partnership with SUEZ, a leading provider of resource and waste management solutions.

Far more than a traditional service provider relationship, NSE and SUEZ have built a genuine partnership focused on identifying, developing and implementing solutions tailored to the specific needs of our operations.
This collaborative approach drives continuous improvement by exploring new ways to optimise waste sorting, expand recycling streams and reduce the volume of residual waste.
Thanks to the joint efforts of the NSE and SUEZ teams, 75% of the waste generated at the Abrest site is now directed to recycling channels, while the remaining 25% is recovered through energy-from-waste processes.
In addition, the volume of residual waste generated was halved compared with the previous year, demonstrating the effectiveness of the initiatives implemented and the commitment of all stakeholders.
One of the most significant achievements was the creation of a dedicated polystyrene recycling stream the first of its kind in the department developed in collaboration with SUEZ.


By combining NSE's commitment with SUEZ's technical expertise, this partnership demonstrates that operational performance, innovation and environmental responsibility can go hand in hand. At the same time, it makes a tangible contribution to the development of a more circular economy.
