In addition, the low selling price of fuel products generated by a biorefinery does not allow the biomass conversion facility to purchase 'pristine' feedstocks composed of clean, homogeneous, and high-quality biomass [ 8].
A profound understanding of the physicochemical properties of lignocellulosic biomass and the analytical characterization methods for those properties is essential for the design and operation of associated biomass conversion processing facilities.
Ironically, most biomass waste conversion facilities, on the other hand, are immensely centralized and capital-intensive installations.
A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and chemicals [2].
An IBR is a complex facility that integrates biomass conversion processes and equipment to produce fuel, power, and chemicals/biochemicals from the biomass.
The National Renewable Energy Laboratory, which is a part of the USA Department of Energy (DOE), defines biorefinery as "a facility that integrates biomass conversion processes and equipment to produce fuels, power, and chemicals from biomass".
An integrated biorefinery is a processing facility that integrates multiple biomass conversion pathways to produce value-added products.
Indeed, efficient supply chains are essential to provide conversion facilities with sufficient quantities of quality biomass at reasonable prices.
Because collecting tons of biomass from rural areas is very expensive, most of these large conversion facilities can often only be co-located with existing agricultural processing mills.
The development of such a fuel source faces several challenges including combustion properties, a reliable supply of raw materials, distance from and access to conversion facilities, production scale and market access for agricultural biomass products.
