Lignocellulosic biomass has a complex body
consisting of heteropolymers such as lignin, cellulose, and hemicellulose with high
tolerance to biodegradation, which is abundant and cheap in nature, and
significantly reduces CO2 emissions in the atmosphere when used in
ethanol production. With the increase of global warming, the concept of
lignocellulosic biorefinery has become a critical focus. There are many
pre-treatment methods which have been developed to distrupt this structure even
they are resistant to biodegradation. In the pre-treatment process, which is
the most critical step in the production of valuable products from lignocellulosic
wastes, a considerable amount of water and chemicals are consumed that affect
the sustainability and economy of the biorefinery industry. This chapter aims
to contribute to the development of new technology and to reduce costs during
the production of high value-added products by examining all available pre-treatment
technologies in terms of water, chemical, and energy consumption.
