Description: The use of fossil resources for energy and products have resulted in environmental, economic and social issues and have encouraged intensive research on alternative raw materials for energy and chemical production. Alternative energy production can be achieved by the use of various renewables such as wind, water and sun, but the industries based on sustainable materials, chemicals and fuels depend mostly on lignocellulosic biomass. Lignocellulosics are abundantly available, relatively distributed worldwide and may alleviate the conflict in use between food and energy. The use of residues from agriculture, such as oat straw and forest residues for energy production settles the food vs. fuel dilemma and adds value to existing crops. Pretreatment research has been focused on identifying, evaluating, developing, and demonstrating promising approaches that enhance the enzymatic hydrolysis of the pretreated biomass at lower enzyme dosages and shorter conversion times. Assessment of biomass pretreatment processes depends on a parameter called the ?severity factor?, which is defined as the combined effect of temperature, acidity, and duration of pretreatment. This paper summarizes pretreatment processing methods, namely, steam explosion and torrefaction, multiple biomass feedstock such as forest and agricultural residues, processing characteristics, and product properties. The paper also discusses the economics of densifying biomass, outstanding challenges, potential for industrial applications of biomass pretreated product and global trends in biomass utilization.
Keywords: : Steam explosion, Torrefaction, Densified solid biomass, Agricultural residues, Forest residues, Energy production.
