Special Issue Information

Dear Colleagues,

We are pleased to welcome submissions for a new Special Issue entitled "New Challenges in Lignocellulosic Biomass Conversion".

The projected depletion of fossil fuels and the deterioration of the environment has prompted researchers to explore renewable and sustainable sources. Lignocellulosic biomass derived from wastes generated by the agricultural and food industries has been recognized as a promising feedstock for the production of both fuels and a wide variety of chemicals and polymers. Catalytic processes are employed to efficiently convert biomass streams towards high value-added products that can be utilized as platform chemicals, fuels and precursors for polymer synthesis. In order to develop viable processes, advanced technologies/methods should be implemented under a biorefinery and green chemistry approach, thus promoting a circular economy model. Furthermore, the other parameters that should be addressed are the sustainability, the environmental impact and the cost-effectiveness of the technologies.

This Special Issue will focus on the application of emerging technologies for the conversion of lignocellulosic biomass to value-added chemicals. Original contributions and reviews are highly welcome. Research areas may include (but are not limited to) the following:

  • Biomass pre-treatment of isolated cellulose, hemicellulose and lignin;
  • Thermo-, bio- and photocatalytic conversion of lignocellulosic biomass streams;
  • The production of fuels, chemicals and polymers from waste lignocellulosic biomass.

We look forward to receiving your contributions.

The integrated production of ethanol fuel through the simultaneous use of various by-products and waste materials is an intriguing concept, as it maximizes the raw material potential while addressing the challenge of managing waste biomass from different technological processes. The efficient utilization of lignocellulosic waste depends on employing a pretreatment method that enhances the susceptibility of structural polysaccharides to hydrolysis. The aim of the study was to assess the possibility of the simultaneous use of corn stillage biomass and beet molasses as raw materials for the production of ethanol fuel. The research focused on optimizing the process conditions for the acid pretreatment of stillage biomass and the enzymatic hydrolysis of cellulose and evaluating the effectiveness of two fermentation strategies: SHF (Separate Hydrolysis and Fermentation) and SSF (Simultaneous Saccharification and Fermentation). The highest hydrolysis susceptibility was observed in biomass pretreated with 2% v/v H3PO4 for 30 min at 121 °C. The maximum glucose concentration of about 12 g/L (hydrolysis efficiency about 35.5%) was achieved even with the lowest enzyme dose, i.e., 7.5 FPU per gram of biomass. The yeast also showed high fermentation activity in media prepared from stillage biomass and molasses, producing about 50 g/L of ethanol regardless of the fermentation strategy used. The complete fermentation of carbohydrates assimilated by yeast confirmed the complementarity of the two raw materials used to prepare fermentation media, emphasizing the high potential of the proposed technological solution for ethanol fuel production.
