Special Issue Information

Dear Colleagues,

Background and History:

The issue of efficient processing and use of less valuable wood species, bio-damaged logs, sawmill residues, cuttings, chips, sawdust, recycled wooden products, and other ligno-cellulosic materials in the production of wood composites is the focus of several scientific research institutes around the world. Wood composites are mostly produced for a particular application and, therefore, the raw materials, additional additives, production processes, as well as finishing and surface treatments are adapted to this. Research into the optimization of material and technological parameters of the production of wood composites with special properties and applications is still ongoing.

Aim and Scope:

Recycled woods, as well as thermally, chemically, or biologically modified woods, have the potential to be a base or complementary raw material for (A) construction wood composites used mostly in construction and transport, such as glued prisms (e.g., glulam), glued boards (e.g., blockboards), glued large-area boards from veneers (e.g., plywood, LVL, etc.), or large-area boards from wood particles and fibers (e.g., particleboards, OSB, MDF, etc.), as well as for (B) decorative wood composites used mostly in furniture and building architecture, such as veneered, laminated, coated or plasma-treated large-area boards.

Cutting-Edge Research:

For this Special Issue, we are interested in research on wood composites in the terms of the raw material conditions also encompasses technological processes, including finishing and surface treatments and their individual properties. The development of wood composites with special properties is also of interest.

What kind of papers are we soliciting:

The papers should be focused mainly on the material composition (i.e., basic components—species, amount, fractions, combinations and distribution of recycled woods, modified woods and other ligno-cellulosic materials; additive components—glues, biocides, fire retardants, etc.), processing, finishing of wood composites for construction, furniture and decorative purposes and on the analysis of their properties.

The Effect of Particles from Rotten Spruce Logs and Recycled Wooden Composites on Changes in the Bio-Resistance of Three-Layer Particleboards Against the Decaying Fungus Coniophora puteana and Mixture of Moulds

Wood-based particleboards (PBs) are widely used in construction and interior applications, yet their durability, particularly against biological degradation, remains a challenge. Recycling wood and incorporating degraded particles from rotted wood can potentially enhance PB sustainability and align with circular bioeconomy principles. This study investigates the biological resistance of the three-layer, laboratory-prepared PBs with varied amounts of particles, from sound spruce wood to particles, and from spruce logs attacked by brown- or white rot, respectively, to particles from recycled wooden composites of laminated particleboards (LPBs) or blockboards (BBs), i.e., 100:0, 80:20, 50:50, and 0:100. The bio-resistance of PBs was evaluated against the brown-rot fungus Coniophora puteana, as well as against a mixture of moulds’ “microscopic fungi”, such as Aspergillus versicolor BAM 8, Aspergillus niger BAM 122, Penicillium purpurogenum BAM 24, Stachybotrys chartarum BAM 32, and Rhodotorula mucilaginosa BAM 571. PBs containing particles from brown-rotten wood or from recycled wood composites, particularly LPBs, had a partly enhanced decay resistance, but their mass loss was nevertheless more than 30%. On the other hand, the mould resistance of all variants of PBs, evaluated in the 21st day, was very poor, with the highest mould growth activity (MGA = 4). These findings suggested that some types of rotten and recycled wood particles can improve the biological resistance of PBs; however, their effectiveness is influenced by the type of wood degradation and the source of recycled materials. Further, the results highlight the need for improved biocidal, chemical, or thermal modifications of wood particles to enhance the overall biological durability of PBs for specific uses. Full article

The aim of this research work was to investigate the feasibility of upcycling poplar (Populus spp.) peeler cores as a by-product from the production of plywood in manufacturing lightweight hybrid poplar and beech plywood panels, containing different ratios (60%, 80%, and 100%) of peeler core sections in the core layer. This corresponds to effective percentages of panel surface glued with peeler core slides of 80%, 64%, and 48%, respectively. The physical properties (density, water absorption, and thickness swelling) and mechanical properties (bending strength (MOR) and modulus of elasticity (MOE)) of the laboratory-fabricated hybrid panels were determined in accordance with the applicable European standards (EN 310, EN 317, and EN 323). The highest MOE and MOR values of 3575 N·mm−2 and 28.1 N·mm−2, respectively, were obtained for the hybrid poplar plywood panels with a thickness of 20 mm and 100% peeler core sections. The use of beech veneer in the face layers did not lead to a significant increase in the mechanical properties. In this case, the MOE and MOR values of the hybrid plywood panels with a thickness of 20 mm and 80% peeler core sections were 5954 N·mm−2 and 35.2 N·mm−2, respectively. Full article
