ABSTRACT
The concept “green bio-refinery” is developed to make use of green biomass as basic material for the fabrication of bio-based goods such as fibers, lactic acids (LAs), proteins, and power (by means of biogas). Upcoming supply chains for actually sustainable and green chemical entities can be established by the assimilation of green chemistry into bio-refineries and also through the implementation of least environmental impact technologies. The first and foremost step in these upcoming bio-refineries ought to be the benevolent extrication of surface chemicals; at this point, the utilization of greener solvents like supercritical CO2 (carbon dioxide) and bio-ethanol, ought to be well-thought-out. The filtrates will frequently be loaded with lignocellulosic, and the efficient partition of the cellulose is a basic confront which might, in the coming time, be supported by greener solvents, like ionic liquids. In order to persuade the huge as well as the varied industrial requirement for aromatics, it is necessary to develop novel ways to procure simple aromatic building blocks out of lignin, which is considered nature’s most important source of aromatics. Fermentation is the other process used nowadays to convert green grassland into an extensive range of bio-platform chemicals 152besides ethanol. Their green chemical translation to superior chemicals is as imperative as their competent production. Hence, clean technologies like catalysis, especially bio-catalysis as well as heterogeneous catalysis also the employment of benevolent solvents, and energy competent reactors are important. Another process called the thermo-chemical processes will also play a vital role in potential bio-refineries for the translation of biomass; thus, once more green chemistry methods should be utilized to go to superior value downstream chemicals.
