Collvert and Challenv join the SULO Group

SULO Group expands its BtoB capabilities in France with the acquisition of COLLVERT and CHALLENV

SULO, leader in solutions for waste management and the circular economy, strengthens its capabilities to serve BtoB customers in France, particularly industrial and collectors, by announcing the acquisition of COLLVERT SAS and CHALLENV SAS. The acquisition, successfully finalized on Thursday, October 5, 2023, marks an important milestone for SULO in France.

Since 1998, COLLVERT and CHALLENV have established themselves as key players in their respective sectors:


COLLVERT by providing waste collectors and professionals with pre-collection solutions for industrial waste,

CHALLENV by distributing an extensive catalog of urban equipment solutions for specialized developers.

25 years ago, I created COLLVERT to provide customized sorting solutions, then a few years later CHALLENV to complete our offering in the field of living environment management. Today, we are passing on these fine businesses. We join the SULO Group with a great deal of enthusiasm and desire. A new page is being turned towards new challenges for our companies, already rich in a partnership spanning more than 20 years.

Pierre Chaudy, founder of COLLVERT and CHALLENV

I would like to welcome our new colleagues from COLLVERT and CHALLENV to the SULO Group. Their entrepreneurial spirit, industry expertise and commercial skills will strengthen our presence in the private sector in France. We look forward to learning from them, as well as sharing the Group's strengths with them.

Jean-Marie VAISSAIRE, President of the SULO Group

By joining forces with COLLVERT and CHALLENV, the SULO Group is reaffirming its commitment to providing value-added services to the industry. This partnership will enable SULO to improve its proximity and responsiveness, thus contributing to the realization of its vision: "to turn today's waste into tomorrow's resources". The SULO Group is thus joined by 18 experienced professionals, bringing their valuable skills and knowledge to strengthen the company's dedicated corporate offering. SULO welcomes them and looks forward to seeing them contribute, along with their 2,200 new colleagues, to the deployment of the Group's vision.
