With its use is primarily restricted to employ as a fuel in pulping boilers, lignin was seen as a waste product or a lesser important by-product of pulping. Recent trends in particular chemical processes make sure that lignin is no more essentially as chemically heterogeneous as it was historically manufactured either by pulping or other means. The chemical companies are now expanding their end-user applications, adding to feedstock supported specifications which can satisfy the requirements of these emerging users as well as integrate new properties into them.

The analysis of lignin in substance purposes can be sub-classified into separate subdivisions because of the enormity of the assignment, even though there are a number of differences between these which are explained as follows:
