Special Issue Information

Dear Colleagues,

There is currently a high and increasing demand to find new sources of energy to ensure global energy security. The correct strategy is develop new sources with both environmental and economic sustainability. Further advances in energy conversion technologies are needed to minimize environmental impacts caused by their use in industry, agriculture and transport. New energy sources must have low CO2 emissions; this is a key element for a sustainable energy future. Biomass and its residues are considered important raw materials for technological innovation in the area of energy. The aim of this Special Issue is to bring together contributions in the area of biomass and energy to enable a smoother path towards achieving worldwide energy security. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

-Biomass waste for energy;

-Thermal analysis as a tool for pyrolysis, gasification and torrefaction studies;

-Biomass thermal and biological conversion;

-New methods of obtaining energy from biomass;

-Hydrogen from sustainable biomass;

-Innovation/improvement in energy production by pyrolysis, gasification and torrefaction;

-Biomass as a feedstock for sustainable catalyst production for energy.

We look forward to receiving your contributions.

In recent years, there has been a steady increase in the interest in changing lignocellulose processing technologies from harmful and nonecological to more ecological and sustainable. Deep eutectic solvents (DESs) and ionic liquids (ILs) are green, efficient solvents/catalysts for biomass pretreatment as well as its further transformation. In many cases, they are used together with biocatalysts. Additionally, in processes where DESs and ILs are used for the pretreatment of biomass, before enzymatic transformation, traces of these solvents can influence the activity of biocatalysts. For this reason, it is important to evaluate the effect of novel, green solvents on the activity of enzymes widely applied in the biomass valorization processes. In this work, we present the impact of chosen DESs and ILs, most often applied in biomass pretreatment and transformation, on the enzymatic activity of popular cellulolytic enzymes and enzymatic preparations (namely, cellulases from Aspergillus niger, Trichoderma reesei, and Viscozyme L). The enzymatic activity was investigated in the process of transformation of cellulose or biomass to glucose. The results showed that many of the solvents tested had a negative effect on enzymatic activity, suggesting a separation of pretreatment and enzymatic processes. Full article
