Abstract

The need for a flexible strategy to meet rising global energy demands has led many academics to concentrate on renewable biofuel made from sustainable resources, particularly lignocellulose feedstock.   After cellulose, lignin is the most prevalent natural renewable polymer. From lignocellulosic material, it can be extracted. Due to the demand for various pure raw materials derived from biomass resources, interest in lignin has recently increased. It has been determined that certain resources, such as walnut shell (WNS), almond shell (AS), neem tree bark (NTB), and babool tree bark (BTB), have additional uses. We cover the removal of lignin from biomass in this essay. In a particle technology lab, sieve studies were carried out utilising a magnetic sieve shaker and a first sieve with a size of 1000 m. The electrical muffle furnace underwent the proximate studies, as well as the final analyses for C, H, N, and S. Lignin yield was obtained using a straightforward extraction process based on NaOH and H2SO4. Effective valorization of lignocellulose biomass into high-value chemicals and biofuels utilizing sustainable, environmentally friendly technology. This paper's major goal is to produce and extract lignin from biomass.  We present and discuss lignin biomass pre-treatment techniques. The ideal process variables that enhance lignin breakdown are examined for green pre-treatment techniques.  The purity of the resulting lignin samples was determined using FT-IR (Fourier Transform Infrared Spectroscopy),EDS,SEM were done. The results show that an extraction process lasting 5 hours, 4 hours, and 3 hours at 100 degrees centigrade, 130 degrees centigrade, and 160 degrees centigrade, using NaOH and H 2 SO 4 for liquor and biomass to liquor ratio of 1:20, is effective.
