Formaldehyde is considered a health hazard, hence the wood-based panels must be within the limits imposed by the strictest regulations regarding the formaldehyde release. New national and international international regulations of formaldehyde emission from wood-based panels widely used in furniture industry were investigated in this study. The results of the study can be useful for the woodbased panel factories to follow the standards and regulations in terms of formaldehyde emission.

Nanocellulose applications in the wood-based panels have gained a great deal in the scientific researches and industrial applications. Utilization of natural and synthetic nanoparticles as reinforcement in the wood-based panels has considerably increased in the last two decades due to their unique properties. The main property of the nanocellulose is its very high surface area. Hereby, the very small use of nanoparticles suh as %1-2 wt% in the composites is enough at a relatively low-cost. Nanoparticles are presently considered to be high-potential reinforcing fillers for the enhancement of the physical, mechanical, electrical/electronic properties, thermal resistivity, fire, durability properties of wood-based panels such as particleboard, fibreboard, oriendted strandboard, and plywood. The nanoparticles are applied to wood based panels dur ing the manufacture and after production. The raw materials such as wood or resin can be treated with nanoparticles or the finished panels can be treated with nanoparticles. In this study, the recent developments in the nano particles, their applications in the wood based panels, and their effects on the panel properties were reviewed

Formaldehyde emission is one of important issues in the wood-based panel industry. Recently, many countries tighten regulations on formaldehyde emissions emitted from wood-based panels due to harmful effect of formaldehyde on the humans. Urea-formaldehyde (UF) resin is the most used synthetic resin as binder in the production of wood-based panels for indoor applications. Disadvantages of UF resin are the formaldehyde emission and low water resistance. UF resin is classified according to the formaldehyde releases, Super E0, E0, E1, and E2, which are from lowest to highest, respectively. Many researchers have focused on the synthetic and natural formaldehyde scavengers for decreasing the formaldehyde emission from the wood-based panels. In this study, recent studies for reducing formaldehyde emission from wood-based boards were reviewed.
