Two kinds of biobased polymers can be developed. The first one corresponds to macromolecular structures existing in nature as cellulose, lignin, starch, alginate and so-on that most of them are probably the ones that derived from well-established cellulosic industries. Nevertheless, the thermal stability of these rich in oxygen structures are limited, they release relatively little heat during burning and are often able to char. Other biobased polymers are made up of molecules synthesized from natural resources. Not only polymers but also all additives used to modify their properties can be biobased to meet sustainable development. Intensive research is devoted to develop flame retardant biobased polymers from various raw resources. These flame retardant biobased polymers can be used directly as they are, alone or as a component of a more complex system. This is especially true when the molecules are phosphorus-rich as DNA or phytic acid or charring as lignin. All the efforts reviewed in this paper, show that a major objective is to develop 100 % biobased materials suitable for applications requiring high flame retardancy level. Different biomolecules from the cellulosic industry are also the most promising in flame retardancy. Manuscript profile
