Special Issue Information

Dear Colleagues,

Engineered wood products were developed to improve the performance of wood in modern bio-based materials with standardized physical-mechanical properties for multiple uses. These products are divided into diversified solutions, which include engineered beams (glued-laminated timber, laminated veneer lumber, laminated strand lumber, parallel strand lumber, oriented strand lumber, etc.), engineered panels (cross-laminated timber, edge-glued panel, oriented strand board, plywood, fiberboard, particleboard, etc.), and, more recently, novel transparent solutions directed to provide transparency and stiffness for new solutions. Furthermore, there are hybrid products that blend different materials in the production of prefabricated composites, for example, trusses, I-joists, structural insulated panels, and wood–plastic composites. Commercially, bio-based panels have been widely used in the production of furniture and construction finishes, and structural composites have gained a growing interest in their uses, e.g., beams and panels, in modern buildings conceived from more sustainable practices and standardized processes. In contrast, transparent wooden products are still in continuous development to replace glass and plastics through more sustainable processes and more biodegradable properties. Recent research has prioritized the development of engineered wood products, which results in the creation of a broad field of study towards sustainable production processes and sustainable performances and uses of these innovative solutions.

This Special Issue of Sustainability aims to disseminate relevant and original research on the sustainable production, fabrication, management, simulation, and applications of these biomaterials. Systematic reviews, critical reviews, meta-analysis reviews, numerical simulations, methods, and original research articles are all welcome (see the Instructions for Authors). Submissions to this Special Issue on the Engineered Wood Products Industry could include (but are not limited to) the following topics:

  • Particle-, strand-, laminate-, and fiber-based panels and beams produced in cleaner engineered processes from any lignocellulosic-based materials based on renewable sources;
  • Sustainable manufacturing, processes, assessments, solutions, and propositions directly related to engineered wood products and biodegradable engineered wood products;
  • Composites based on wood, bamboo, and other easily renewable bioresources (and their residues);
  • Solid wood impregnated with resins to reach better stability and performance;
  • Wood resins and wood gluing processes focused on more sustainable features and performances.

When submitting your paper for evaluation, please clearly specify: (i) how the research fits this Special Issue and (ii) identify which coupled systems or quantified feedback loops your research addresses.

Based on the background of the limited availability of raw materials in the forestry and timber industry, increased attention applies to sawmill by-products and their potential for future applications. Within the present research, the suitability of a natural binder based on different casein sources, superficially lean curd with different lime ratios, for the production of bark insulation panels from larch bark (Larix decidua) in fraction 12.5–4.0 mm with densities below 500 kg/m³ were discussed and physical and mechanical properties evaluated. In order to obtain a benchmark, control boards bound with powdery casein and urea-formaldehyde resin were fabricated. The evaluation of physical-mechanical characteristics indicated the lean curd panels to be competitive with the references and commercially available insulation materials, whereby higher values could be achieved consistently with a lower lime content of 20% compared to 31%. The best moisture resistance and water absorption were observed with a lime ratio of 31%, whilst thickness swelling and mechanical characteristics were best with a lime content of 20%. Particularly with regard to mechanical properties, panels containing a low proportion of lime in the lean curd blends delivered convincing results, e.g., with an average IB of 0.19 N/mm2, MOR of 1.43 N/mm2 and C of 1.70 N/mm2. In terms of thickness swelling, lean curd adhesives generated unsurpassed values of approximately 11% compared to the casein and urea-formaldehyde references. Additionally, as described in the relevant literature, a considerable influence of density on the mechanical behavior of composite materials was observed. Partly, the lime content significantly influenced the panel properties. The study proved that natural binders based on lean curd and lime are suitable for the production of bark insulation boards and represent a serious alternative to synthetic, oil-based adhesive systems. The results are promising with regard to the market situation due to the availability and pricing of raw materials and technical requirements and demonstrated great potential for further research efforts.

Recently, both authors led a comprehensive review to discuss cross-laminated timber (CLT) as an engineered wood product, addressing the information and discussion on this building input in terms of the main details, materials, production forms, performances, codes, sustainability, applications, and perspectives for residential uses. The current scenario of CLT developers was raised in that previous paper as one of the missing factors in the available literature, and was the reason why this gap became the main goal of the present study. A global perspective was driven to provide information and discussion to every possible stakeholder. A systematic review on this sector was carried out, through the Web of Science and Scopus databases, to collect information and confirm this gap, using a representative method. CLT manufacturers were identified by their own websites, using a blended strategy formed by the systematic review results combined with the search for these companies using the Google search engine. Nearly a hundred CLT developers were identified and analyzed, in a representative sampling process. Results demonstrated that the CLT industry has manufacturing plants on the five habitable continents, which evinced a global commercial interest in this timber forest product. Despite the global presence of this mass timber product, most producers are concentrated in the northern hemisphere, despite being willing to serve international markets. Full article
