Lignin Coating
Lignin is a natural component of wood that acts like a glue, binding cellulose fibers together and helping to regulate water content within the wood. It also contributes to wood's brown color.
In paper-making, lignin is often separated as a by-product. Traditionally, it has been burned for energy or used in the production of chemicals, but research is increasingly exploring its conversion into valuable products such as biofuels and other chemicals. Lignin has a range of properties that could be used in various material applications, from bioplastics to adhesives.
In these simple experiments, lignin was tested in combination with carnauba wax as a coating, and then applied to paper which added it's hydrophobicity.
Also, in simple terms, lignin can be mixed with various types of biomass, which then can formed and dried. In this process, lignin acts as a natural binder, helping to hold the materials together.
