Abstract
transformation: at a given developmental stage, molecules with various functionalities, such as those with biocidalor repellent activities against biological aggressions, are synthesized and impregnate the various cells of theirwood. The produced metabolites, whose nature and quantity vary widely from one species to another, but alsowithin the same species depending on the growth conditions of the individuals, can be extracted by variousprocesses. These chemical compounds can be used in a variety of ways, notably in the development of additivesand protective agents for functionalizing materials and improve their technological properties. These extractionprocesses could gradually replace conventional petroleum products. The study of the unique biodiversity of thetropical forest could enable the identification of new molecules of interest in the context of such valorization. Inthis respect, the study of Guiana’s forest species represents a rich field of research for exploring the functionalitiesof Amazonian wood extractives. This article provides a non-exhaustive overview of the work carried out in thisfield research units and the recent innovations that have emerged from the activities carried out around thevalorization of extractives to improve the shaping and properties of bio- and geo-sourced materials intended forconstruction in tropical environments.
