Considerable research efforts have been put into different attempts for fragmenting lignin, a biopolymer found in wood. Wood processing is done globally for production of paper, paper products, different kinds of biomass and biofuel. Lignin is structurally a big part of wood composition with 15-30 % of its whole mass and hence, there is need for it to be used. Usage of lignin as a wholesome material is problematic because of its complex and large structure, so it must be pretreated into smaller molecules for eventual use. This project reviews usage of high power ultrasound (US) for fragmentation of lignin for said purpose. Methods researched for its fragmentation are usually expensive and lasting, therefore US could potentially be better option for pretreatment. This project highlights spectroscopic methods used for detecting if fragmentation with this approach is possible and potential products gotten.
