Pretreatment of lignocellulosic biomass for acetic acid co-valorization

Abstract

The use of renewable resources is nowadays a well-established practice and a general policy to address the fossil fuel depletion, as well as the continuous increase in greenhouse gas emissions. Several approaches have been adopted, with a growing trend toward developing new technologies that target efficiency, sustainability and feasibility. Because it closes the carbon cycle, biomass has a significant potential as renewable source, and not exclusively for the production of energy. Thus, similar to the traditional refinery, the fractionation and conversion of sources to generate, separate and purify different products is also applicable to biomass. Hence, the concept of biorefinery enables the use of renewable feedstocks to obtain bio-based fuels, chemicals and materials in a greener and eco-friendlier manner. Moreover, lignocellulosic biomass (LCB) used as second generation feedstock, encompasses plenty opportunities due to features such as availability, price and versatility....
