Abstract

According to environmental issues and limited fossil resources, the use of renewable
and biodegradable resources has been considered very important. Forest biomass is
the most abundant source of renewable and carbon-rich organic matter on land that has a
desirable potential as raw material for a wide variety of industrial and domestic products,
including paper, lumber, chemicals and advanced materials such as fuel and biodegradable
polymers. By-products obtained from bio-refinery lignocellulosic biomass include
hemicelluloses derivatives (furfural, xylitol, biodegradable polymers and polymeric
paper strength) and lignin derivatives (turpentine, tall oil and raw material for production
of plastic & binder) are remarkable. These products can be manufactured with pulp and
paper or dissolving pulp from lignocellulosic resources. So one of the important goals in
biorefinery is to create value-added in black liquor from lignocellulosic materials cooking
in pulp mills, which in addition, in production of pulp and paper there are also some byproducts
as well. Finally, biorefinery has provided an economic opportunity to enhance the
economic strength in this industry
