Lignin is an aromatic natural or bio-polymer. It is the natural glue that supports the tissues of most plants in the formation of cell walls, jointly it contributes their structural capacity and their defences against pests and pathogens.

Wood is the main source of lignin, accounting for about 30% of its weight, but in lesser amounts it is also a natural component of grasses and straw, combined it is the second most abundant class of biopolymer on Earth.

Lignin is a generic term that describes a large group of aromatic biopolymers, the chemical composition of which varies from species to species, but traditionally it considered to be formed from the oxidative coupling of three monolignols: p-coumaryl, coniferyl, and sinapyl alcohols (Boerjan et al., 2003; Ralph et al., 2004).

In terms of building materials, in particular wood waste, lignin can be separated from its base material by bio-bleaching, and can replace fossil-based phenols that are used as resins for plywood, oriented strand board (OSB), laminated veneer lumber (LVL), paper lamination and insulation material. It also has a variety of potential applications including as a filler for thermoplastic biomacromolecules to improve mechanical properties, such as water resistance, and thermal stability.
