Extraction and employment of lignin from waste biomass
Lignin is a natural material that is responsible for structural strength in plants and even binds cellulose and hemicellulose. It is most abundant raw material present on the earth as a natural & vital waste product so that it can be used as a material to make adhesives and composites that can be potently used in several industries. In this investigation we have isolated the lignin from wood dust by lignin extraction process, where pretreatment of sample was done by 2.5 % (w/v) sodium hydroxide and black liquor was formed. Further lignin was extracted by the treatment with different percentage of sulphuric acid (v/v). 20 % (v/v) sulphuric acid treatment was found quite effective for lignin extraction as compared to others. These separate batches of lignin were further utilized to form different adhesives as well as composites.
