Abstract: The purpose of the invention is a composition for fire fighting, characterized in that it includes at least a first compound in the form of a vegetable derived powder, soluble in cold water and thickening; a second compound in the form of a vegetable derived powder, insoluble in cold water but thickening and retaining water in hot water or in the presence of steam; a third compound including at least one agent encouraging the Maillard reaction of at least the first and/or second compounds, and water. The invention also relates to formulations of said composition.

Abstract: The invention relates to methods for making panels of an expanded renewable material, essentially starch, characterised in that it comprises: extruding unit members or strings having a small section and a substantial length L; assembling by juxtaposing and gluing these strings thus obtained along their longitudinal axis in order to produce a layer having a width A; superimposing and assembling by gluing at least two of said string layers in order to produce a block having a height B and a length L, said block thus exhibiting a section with a side A and a side B having dimensions related to the number of assembled unit members; and cutting said block transversally relative to the longitudinal axis along a length l in order to obtain plates having a maximal section of A×B with a selected thickness l. The invention also relates to a related device.
