Abstract (en)

[origin: WO2011002296A1] A method for treating lignocellulosic parts for producing foamed or foam-like parts, including: -drying the lignocellulosic parts, the drying involving removing water, wherein the drying is achieved by applying at least one liquid drying agent that dissolves and/or at least partly replaces the water, wherein preferably the drying agent is a swelling agent for lignocellulose; and -chemical modification, by etherification of the dried lignocellulosic parts; wherein the chemical modification is such that a volume of the lignocellulosic parts is increased by at least 25% with respect to an initial volume of the parts.
