“…Recently, Hong et al successfully produced three-layer MDF panels from hammer-milled surface-laminated MDF. The authors showed that the substitution of >20% recycled fiber results in panels with improved properties in terms of formaldehyde emission and thickness swelling [ 40 ]. MDF Recovery© is a patented and commercial process based on a gentle hydrolysis followed by spray defibration.…”

Cascading Recycling of Wood Waste: A Review

et al. 2021

Wood is an increasingly demanded renewable resource and an important raw material for construction and materials. In addition, new consumption habits are leading to the production of ever greater volumes of waste wood, which constitutes a feedstock that can be mobilized for the cascade production of new materials such as particleboard. However, current legislation and wood waste recycling processes need to be improved in order to maximize the volumes that can be reused and to upgrade the properties of the recycled wood. This review describes wood waste flows and volumes available in Europe, the current French and European legislation, and the innovations under development in this field: innovative automated sorting techniques, physical-chemical processes for cleaning residual glue from the surface of wood particles, cleaning of MDF, and bioremediation processes for cleaning hazardous wood contaminated by heavy metals or creosote.

“…Several methods have been established regarding the recovery of recycled materials, such as chips and fibers, from wood-based composite waste (Conroy et al 2006;Hamad et al 2013;Hong et al 2020;Kharazipour and Kues 2007;Lubis et al 2018a;Mantanis et al 2004;Zeng et al 2018). Table 4 briefly shows four different methods that can be applied to recover the recycled fibers from waste MDFs, namely mechanical, hydrolysis, hydrothermal, and chemical-hydrolytic.…”

“…Moreover, MDF made from recycled fibers is difficult to compress but easier to spring back. Thus will contribute to the variations in panel density of recycled MDF (Dazmiri et al 2018;Hong et al 2020). 1.2-1.5 15-25 5.0-6.0 2.6-2.8 5.5-6.2 0.1-0.5 (Bütün et al 2018;Hong et al 2020;Hwang et al 2005;Lubis et al 2018a;Lykidis and Grigoriou 2008) Refining recycled 1.1-1.4 15-20 6.2-6.3 1.5-1.6 9.0-10.2 1.0-1.5…”

Medium density fiberboard (MDF) is an engineered wood product that has density and specific gravity similar to solid wood, ranging from 600 to 800 kg/m3 of density and 0.6 to 0.8 of specific gravity. This makes MDF suitable to partially replace solid wood, particularly for interior application. Approximately over than 100 million m3 of MDF are produced in 2020, resulting in a large amount of waste MDF will be generated in the next 20 years. MDF is produced using urea-formaldehyde (UF) resins adhesive. UF resins adhesive is a poly-condensation product of urea and formaldehyde via an alkaline acid two-step reaction. Sustainable MDF production is required as the world is facing climate change and deforestation. Recycling is a way to support sustainable production in the engineered wood products manufacturing. Many attempts have been done to find ways to recycle waste MDF. The main problem is UF resins, which bond the MDF panel fibers. In order to re-manufacture the waste MDF into new recycled MDF, UF resins should be eliminated from the waste MDF before being used. The presence of UF resins in MDF can interfere with the utilization of the recycled fibers, whether it will be used as a raw material for new MDF or other composite products. This paper reviews the process of removal of cured UF resins from waste MDF panel by considering the hydrolytic stability of cured UF resins for MDF recycling, providing a comprehensive review of how cured UF resins can be removed from waste MDF and characterization of recycled fibers obtained from recycling prior to re-manufacturing of recycled MDF panel.Keywords: hydrolysis, medium density fiberboard, resin, recycling, resin removal, urea-formaldehyde

This review deals with recent works on the process and technological aspects of wood-plastic composites (WPCs) manufacturing.The term WPCs relates to any composites that contain plant (including wood and non-wood) fibers and thermosets or thermoplastics. Recent progress relevant to wood-plastic composites has been cited in this review. This articleintended to outline the results presented on wood-plastic composites focusing on process and technological aspects such as raw materials, fabrication, mechanical, physical, thermal, and morphological properties. The manufacturing process of WPCs is an important aspect of WPCs production. Manufacturing methods like compression molding and pultrusion have some limitations. Extrusion and injection molding are the most widely used manufacturing processes in WPCs due to their effectiveness. Recent developments dealing with WPCs and the use of different kinds of nanofillers in WPCs have also been presented and discussed. Nanoclays are widely used as nanofillers in WPCs because they represent an eco-friendly, readily available in large quantity, and inexpensive filler. WPCs are finding applications in many fields ranging from the construction to the automotive industry.Keywords: additive manufacturing, adhesion, fabrication techniques, mechanical and physical properties, wood-plastic composites
