    For light-weight porous materials, there is an increasing interest in replacing synthetic materials by biomaterials such as wood fibres. In this study, the effects of different wood fibres and the influence of nanofibrillated cellulose on foam formation and solid material properties were elucidated. Different methods such as oven and freeze drying (lyophilisation) to dry the formed foams were studied in order to obtain solid foams while preserving the porosity. For improving the strength properties of fibrous network, enzymatic methods were used to cross-link the fibres. The solid foams were tested for density, pore structure and compression strength by mechanical testing and microscopy
