Lignin and Lignin-Derived Compounds for Wood Applications-A Review

Improving the environmental performance of resins in wood treatment by using renewable chemicals has been a topic of interest for a long time. At the same time, lignin, the second most abundant biomass on earth, is produced in large scale 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. Despite this, there are only few lignin-derived wood products commercially available. This review provides a summary of the research on lignin application in wood adhesives, as well as for wood modification. The research on the use of uncleaved lignin and of cleavage products of lignin is reviewed. Finally, the current state of the art of commercialization of lignin-derived wood products is presented.

Automated summary

Improving the environmental performance of resins in wood treatment with renewable chemicals is a popular topic, while lignin, the second most abundant biomass, is mainly used energetically despite its potential applications in wood adhesives and modification. Commercial availability of lignin-derived wood products remains limited despite scientific attention.
