About us

Founded in 1991 by Stéphane Ledentu as a wood trading and forest management firm, the SLB Group initiated its international expansion as of 2007, in Romania, through the acquisition and management of forested massifs.

Additionally, since 2008, the SLB Group has been developing an innovative afforestation concept in Brazil, reconciling the ecology with sound, profitable forestry investments. SLB created, in 2011, its carbon offset brand Econologic Program®.

With over 10,000 Ha under management, the Group is diversifying its activities by producing and marketing a wood-based organic amendment, usable in organic agriculture. This innovative and high quality product is now offered to both corporate clients and consumers.
