Definition: Lignin is the most abundant aromatic polymer in nature and the second most abundant biomass on earth. In paper production and other processes, lignin is obtained as a side product and mainly used energetically. The use of lignin in wood adhesives or for wood modification has received a lot of scientific attention.

Definition: Glycosides have been identified in almost every type of plant tissue including leaves, roots, stems, and reproductive organs (i.e., flowering and fruiting bodies). The direct role of glycosides in plants is still uncertain, but it is hypothesized that glycosides were a part of the “chemodiversity” necessary for plants to survive. The addition of sugar moieties onto hydrophobic aglycones changes the overall polarity and water solubility of the aglycone. The increased polarity of the glycoside allows for detoxification, storage, and transport within the plant.

Definition: Modern developments in cellulosic materials for oil spill removal are briefly showcased in this entry. Different types of lignocellulosic textures and different modification techniques and preparation methods are explained. Materials were classified into 3D-materials such as hydrophobic and oleophobic sponges and aerogels, or 2D-materials such as membranes, fabrics, films, and meshes. Majorly, 3D-materials showed clear correlation between porosity and density, and their absorption behavior. Moreover, it was shown that nanocellulosic precursors are not exclusively suitable to attain considerable absorption performance. This finding can lead to developments in cost- and energy-efficient production processes of future cellulosic oil spillage removal solutions.
