Lignin, complex organic polymer that, with cellulose, forms the chief constituent of wood. It is second to cellulose as the most abundant organic material on Earth, though it has found relatively few industrial uses other than as fuel. It provides compre
The meaning of LIGNIN is an amorphous polymer related to cellulose that provides rigidity and together with cellulose forms the woody cell walls of plants and the cementing material between them.
This article provides a critical review of forty-two peer-reviewed LCAs regarding lignin and derived products. Methodological issues and their influence on the LCA results include the choice of the modeling approach and system boundaries, functional unit definition, impact categories considered, type of...

Lignocellulose nanofibrils (LCNFs) are nano-objects produced in aqueous suspension by industrially adaptable methods, with a high yield, low production cost and the potential to replace or complement delignified cellulose nanofibrils in their current applications. To this end, it is necessary to unders...

Klason ligninis the residue obtained after totalacid hydrolysisof the carbohydrate portion of wood. It is agravimetric methodfor determining lignin directly in woody materials, for example, by TAPPI Standard T 222. This method is not used for routinequality controlin the mill but has uses in the...
Lignin is the second most abundant polymer on Earth, after cellulose, and it is an affordable renewable resource with potential industrial use. However, the structural definition of lignin has never been as clear as that of other natural polymers, such as cellulose and proteins, due to the ...
Table 1 shows the calculated severity factors for the different combinations of temperature and time. Due to the definition of Equation (1), an increase in the holding temperature influences more the severity factor than an increase in time. For example, increasing the holding time from 60 to ...
