stronger commitments for a softer impact.

At SEL Groupe, CSR is at the heart of our commitments.
Employees, customers, partners, we are all concerned and stakeholders.
As an SME in Flanders, in a region that has inherited a social and environmental record that has been burdened by intense industrial mining activity and two world wars, we are aware that we can take action through our company.
