Special Issue Information

Dear Colleagues,

With the depletion of petroleum resources and the growing concern about sustainability and energy demand, the production of high-value products from renewable resources, especially woody biomass, has become a trending research topic. Woody biomass comes from trees and woody debris or residues that cannot be used for timber. It is a by-product of forestry operations and the forest industry. This material, highly available, represents a huge untapped biomass resource, and its removal could not only improve forest health and reduce the risk of catastrophic wildfire, but also play an important role in helping to achieve climate targets through decarbonization processes.

There are many challenges regarding the use of woody biomass. Its use in efficient energy-conversion facilities, the chemical processing of biofuels, composite materials, nanomaterials, organic chemicals, biomaterials, etc., are some examples of its potential economic utilization. The logistics of accessing and pre-treating woody biomass also present challenges for consideration.

We welcome and solicit manuscripts in the following areas: the catalytic conversion of woody biomass; improved woody biomass biochemical and thermochemical processes to produce liquid and/or gaseous biofuels; new strategies for woody biomass pre-treatments and in situ utilization; novel technologies to achieve highly selective dissolution and the efficient conversion of lignin, cellulose and hemicellulose; the fractional conversion of cellulose and lignin for the maximum retention of small molecules and structures; the utilization of woody biomass products, etc.

Maximizing sustainable woody biomass utilization through efficient and sustainable processes to generate bioenergy, and/or diversified high-value products, will help not only climate change mitigation, but will also contribute to reducing our dependence on fossil resources.

Eucalyptus globulus sawdust is a residue from the pulp and paper industry which has been underutilised and undervalued. The thermochemical liquefaction of sawdust can be considered an alternative for recycling this residue, as it results in the production of a bio-oil that, when extracted in water, allows the obtention of an aqueous solution composed of carbohydrates. The sugars resulting from the aqueous fraction of bio-oil can be valued by and applied in the industry to produce sustainable materials. For the first time, the sugar composition of the aqueous extract of bio-oil was disclosed, identified, and quantified by a high-pressure liquid chromatograph (HPLC) coupled to a refractive index (RID) detector containing fructose (36.58%) and glucose (33.33%) as the main components, sucrose (15.14%), trehalose (4.82%) and xylose (10.13%). The presence of these sugars was further confirmed by two-dimensional (2D) 1H-13C heteronuclear single-quantum correlation–nuclear magnetic resonance (HSQC–NMR) spectroscopy. Fourier-transform infrared (FTIR-ATR) and elemental analyses were also used. In addition, the pathway leading to the identified sugars is also suggested. Full article

The isolation and bottom-up assembly of nano-cellulose by using microorganisms offers unique advantages that fine-tune and meet the main key design criteria of sustainability, rapid renewability, low toxicity and scalability for several industrial applications. As a biomaterial, several properties are required to maintain the quality and functional period of any product. Thus, researchers nowadays are extensively using microorganisms to enhance the yield and properties of plant nanocellulose. A microbial process requires approximately 20%–50% less energy compared to the chemical isolation process that consumes high energy due to the need for intense mechanical processing and harsh chemical treatments. A microbial process can also reduce production costs by around 30%–50% due to the use of renewable feedstocks, fewer chemical additives, and simplified purification steps. A chemical isolation process is typically more expensive due to the extensive use of chemicals, complex processing steps, and higher energy requirements. A microbial process also offers higher yields of nanocellulose with well-defined and uniform dimensions, leading to improved mechanical properties and enhanced performance in various applications, compared with the chemical isolation process, which may result in a wider range of nanocellulose sizes, potentially leading to variations in properties and performance. The present review discusses the role of different microorganisms (bacteria, yeasts and fungi) in the isolation and production of nanocellulose. The types and properties of nanocellulose from different sources are also discussed to show the main differences among them, showing the use of microorganisms and their products to enhance the yield and properties of nanocellulose isolation. Finally, the challenges and propositions regarding the isolation, production and enhancement the quality of nanocellulose are addressed. Full article

Abstract: Forest wood biomass can be used as a renewable resource for the sustainable production of fuels and chemicals. In this study, the solvent extracts was analyzed by FTIR, IH NMR, 13C NMR, 2D-HSQC NMR, GC-MS, and TOF-LC-MS. The results revealed that the bark of P. orientalis con-tained a large number and diversity of chemical compounds, such as aromatics, aliphatics, alkanes, aldehydes, ketones, carboxylic acids, and esters. These chemical components have the potential as raw materials for bio-oil, drug, and biomedical production and can also be used in many industrial and agricultural fields as a promising new material. In addition, several actives molecules could be used as drug and biomedical active ingredients for anti-cancer and anti-inflammatory. Meanwhile, the fast pyrolysis of Platanus orientalis L. bark (POL-B) with nano-catalysts (Co3O4, Fe2O3, and Co3O4/Fe2O3) were investigated by Pyrolysis-gas chromatography/mass spetrometry (Py-GC/MS) and Thermogravimetric analyzer coupled with FTIR spectrophotometer (TG-FTIR) to obtain high quality fuels and high value chemicals. TG results revealed that nano catalyst had a significant effect on the pyrolysis of P. orientalis bark. The Py-GC-MS results revealed that the products of the fast pyrolysis of P. orientalis bark contained many high values chemicals and high quality bio-oil. The nano-catalysts promoted the production of aromatics, phenols, ketones, olefins, furans, and alkanes compounds.
