The present invention relates to a
composite material based on foamed wood, which comprises a wood component with particle size in the range of from 1 nm to 5 mm, hemp
protein as a stabilizer, and a
foaming agent, wherein said wood component is in the form of
wood flour, wood fibers,
lignin and / or industrial hemp; and wherein the
foaming agent is selected from the group comprising synthetic and natural foaming agents, wherein - synthetic foaming agents are selected from the group comprising
fatty alcohol ethoxylate of the general formula R(OCH2CH2)nOH,
fatty alcohol ethoxysulfate of the general formula R(OC2H4)nOSO3H, alkaline salt of
fatty alcohol ethoxysulfate of the general formula R(OC2H4)nOSO3M, alkaline salt of fatty
alcohol sulfate of the general formula ROSO3M and poly(
ethylene glycol) methyl
ether methacrylate of the general formula H2C=CCH3CO2(CH2CH2O)nCH3, wherein R is (C8 to C22)
alkyl, n is an integer in the range of from 1 to 12, and M is selected from K+, Na+ and NH4+; - natural foaming agents are selected from yeasts of the Saccharomycetaceae family, wherein said
composite material has density in the range of from 30 kg / m3 to 610 kg / m3 and pore size in the range of from 0,1 nm do 4 mm. The invention further relates to a method of production of said
composite material and to its use.
