“…The results show the favorable aspects of the use of furniture disposal particles in the production of new particulate panels due to the presence of paraffin in its original composition, which can positively influence the dimensional stability of panels produced. The increased presence of residual resin and paraffin of original panels contributed to the reduction of water absorption and thickness swelling of panels evaluated, corroborating studies by Weber & Iwakiri (2015) and Zamarian et al (2017).…”

“…Such process involves collection, separation and cleaning, allowing fewer new products to be manufactured, saving raw material, inputs, and contributing to reduce energy consumption. Zamarian et al (2017) reported that wood waste from sources such as furniture production, packaging and demolition can be reprocessed in industrial grinders and processed into chips for use as raw material in the manufacture of new wood products. The grinding process is simple, efficient and inexpensive, being technically and economically interesting as a way to add value to waste, providing supplies to agglomerated panel industries.…”

This study evaluated the quality of the particleboard produced with particles generated from mobile discharges with mixture of equal parts of industrial particles of Pinus. The material was collected and processed in the form of chips by a company specialized in waste recycling. The experimental plan consisted in producing panels with nominal density 0.55, 0.70 and 0.85 g/cm 3 , and urea-formaldehyde resin of 8, 10 and 12%. The increased density and resin content contributed to improve the physical and mechanical properties of the panels. The panels produced with nominal density of 0.70 and 0.85 g/cm 3 , and 10% resin content, showed better feasibility of using mobile discharges particles in a proportion of 50% mixture with particles of Pinus industrial production of particleboards.

“…A further reason for thickness disparities were possible localized density variations within individual panels and consequently between replicates. Internal density variations are frequently reported in experimental settings where panels were manually formed and minimal automation during the fabrication process occurred 1,43–45 . A comparison of variant density and variant thickness at EMC is presented in Figure 4.…”

This study investigated Australian hemp hurd (Cannabis sativa L., “Frog One”) as a lignocellulosic raw material for ultra‐low‐density hemp particleboard (ULHPB) with densities ranging from 213 to 309 kg/m3. The hurd was first milled and fractionated into three particle size categories, that is, fine (F), medium (M), and coarse (C). Twelve unique ULHPB variants were then fabricated comprising varying particle loadings from four particle size mixes, that is, 100% C, 100% M, 50%/50% CM, 25%/50%/25% CMF, and adhesive contents of bio‐epoxy (EPX), phenol resorcinol formaldehyde (PRF), and emulsifiable methylene diphenyl diisocyanate (MDI), respectively. The panel assessments, conducted in accordance with the Australian reconstituted wood‐based panels standard AS/NZS 1859.1 (2017), revealed a significant effect of particle dimension on most physico‐mechanical properties. Furthermore, the resination method and pressing temperature controlled post‐cure panel expansion and additional panel characteristics. Notably, MDI‐ULHPB exhibited drastically different behavior and properties compared to EPX and PRF equivalents, demonstrating greater bending strength, stiffness, screw withdrawal strength, and dimensional stability. Importantly, all MDI variants conformed to the 15% thickness swelling limit for moisture resistant particleboard. Surface lamination of MDI‐bonded ULHPB with sheets of aluminum, Masonite, and Kraft liner significantly improved the inherently low flexural properties, suggesting the potential suitability of ULHPB as a core layer in lightweight sandwich composite panels. The integration of agricultural by‐products, such as hemp hurd, into engineered building materials presents a promising opportunity to mitigate the depletion of finite timber resources and aligns well with circular economy principles.Highlights Utilizing agricultural residue as sustainable raw material in building products. Hemp hurd enables ultra‐low‐density particleboard with thermosetting resins. Coarse particle size mix enhances mechanical performance in panels. Panel characteristics controlled by resination method and pressing temperature. Lamination enhances functionality of lightweight hemp hurd sandwich panel.

“…The particleboards produced had a density of 700 kg m −3 , and urea-formaldehyde resin was used to seal them in a proportion of 10% solids—the dry weight of particles and 1% paraffin emulsion. The study showed the potential of using milled furniture particleboards to produce new particleboard [ 44 ].…”

This is a bridge between circular economy issues and wood-based panels technology, especially particleboards. Because these composites contain a significant amount of non-wood raw material (10–12% thermoset resin, high hardness laminates, among others), their mechanical recycling leads to an uncontrollable reduction in produced particle size. This problem can be especially significant since the particleboards can be intended for multiple recycling due to the shortening of their service life. This research aimed to produce particles in the cycle of multiple re-milling particleboards and evaluate the selected properties of the produced particles and particleboards. Thus, the response to the following scientific problem can be given: what factors qualitatively and quantitatively influence the properties of the particleboards produced by multi-re-milled particles? The novelty of this research is the approach to recycling the raw materials from particleboards in fully controlled conditions, providing the characterization of produced particles and producing particleboards with close-to-industrial parameters, and, finally, evaluating the features of produced particleboards in the light of raw materials used. The results confirmed that subsequent mechanical recycling of particleboards, where the other panels are made entirely of second-milling particles, leads to an unprofitable and unacceptable reduction in the mechanical properties of the panels. The physical parameters, such as thickness swelling and water absorption, are improved, but this can be the result of increased content of chemical ingredients, which negatively influence the hygienic features of panels (emission of formaldehyde and total volatile organic compounds—TVOC). Further research should be directed towards estimating the optimal addition of mechanically recycled particles to particleboard production.
