Special Issue Information

Dear Colleagues, 

The cornerstone of the circular bioeconomy is carbon-neutral renewable bioresources for the production of bioenergy and biomaterials, which is the basis for sustainable global development. Lignocellulose is a heterogeneous, anisotropic composite material comprising cellulose, hemicellulose and lignin. The presence of three polymers with pronouncedly different chemical structures and properties complicates its processing. Waste wood biomass mainly represents low-value by-products and residues of industrial wood mechanical processing and forestry. For the rational and economical conversion of lignocellulose into value-added bio-products, the effective biorefinery technologies based on physico-mechanical, chemical, biochemical and thermochemical processes and appropriate engineering are developed. The growing interest is related to nanocellulosic materials, due to their useful physicochemical properties that enable their applications in various fields. The newly developed approaches in the lignocellulosic biorefinery technologies and feedstock engineering will contribute to the manifested growth of the volume of new commercialized lignocellulose-based bioproducts on the market and support the sustainable development of the economy.

This Special Issue acknowledges the most recent advances in lignocellulose biorefinery engineering, nanotechnologies, and lignocellulose-based materials in the area of composite materials, packaging, energy, and environment protection.

Potential topics include, but are not limited to:

  • Biorefinery technologies for energy, chemicals and materials;
  • Nanocellulose, nanotechnologies, nanomaterials and application;
  • The functionalization and modification of lignocellulose;
  • Lignocellulosic fillers for “green” composites and wood–plastic composites;
  • Lignocellulosic materials in packaging;
  • Wood biomass in particleboards, fiberboards and inorganic binder–wood composites;
  • Lignocellulose as adsorbents;
  • Liquid wood, liquefaction technology and application;
  • Polyols from lignocellulose.

In the last two decades, there has been increased interest in research focused on developing innovative polymer composite materials for food packaging, obtained by compounding polymers with organic fillers, intended for the manufacture of food storage containers. Woodplastic composites (WPCs), due to high content of lignocellulosic filler, are consideredbiocomposites and can be used for the fabrication of such types of containers. Their formulations include, along with the matrix and the filler, functional additives. One of the most important considerations while developing a food packaging material is to choose eco-friendly additives. The suberinic acids (SAs), extracted from birch outer bark by hydrolysis in KOH water solution, were examined as lubricants in the formulation of recycled polypropylene/polylactic acid (rPP/PLA) composite filled with the alkali-treated milled birch shaving microparticles and proceeded by extrusion and injection molding. The incorporation of Sas in a birch wood-rPP/PLA composite was performed by treaing the wood microparticles with the SAs water suspension at the defined concentration. Their presence at the optimal content in the composite improved its processing by reducing the extruder rotor torque and injection pressure, which increased the mechanical properties and decreased the wettability of the composite.

The conversion of lignocellulosic waste ascends as a promising path to generate new materials with wide industrial and environmental uses. Pyrolytic biochar (PBc), hydrochar (Hc), and activated hydrochar (AcHc) produced from the waste of Picea Abies bark were considered bio-based sorbents for lead uptake from aqueous effluents. PBc was obtained through slow pyrolysis (550 °C), while Hc resulted under hydrothermal conversion (280 °C). In order to enhance the specific surface, Hc was subjected to a physical activation, resulting AcHc. All three carbonaceous materials were prepared through relatively simple processes from a readily locally available resource. The carbonaceous materials were characterized using infrared spectroscopy and scanning electron microscopy. The Pb (II) removal has been tested in batch mode on a synthetic monocomponent wastewater matrix, as well as on a real mine drainage effluent. A significant effect of pH was observed, while the equilibrium was achieved in a short time, about 60 min for PBc and Hc and 120 min for AcHc. Langmuir model predicted a maximum adsorption capacity of 15.94 mg/g for PBc, 9.99 mg/g for Hc, and 37.46 mg/g for AcHc. All materials studied had good uptake capacities for lead with no drastic effect of typical coexisting species. Full article
