Conventional particleboards account for over 30 Mm3 per year in production for many applications and are composed of wood particles bonded by a synthetic adhesive, usually containing cancerogenic formaldehyde. This is very important, especially in in-house environments required by air quality control. Therefore, it is very important to develop the industry looking for sustainable adhesives, preferably from natural resources. Suberinic acids (SA) obtained from birch (Betula) outer bark were investigated in LSIWC, showing good adhesive properties and high suitability for particleboard production from birch wood particles (Rizhikovs et al., 2022).
Cellular wood material (CWM), like Dendrolight, is a lightweight, engineered wood product designed for furniture, door production, and transportation components (Iejavs and Spulle, 2016). However, due to the sawn longitudinal grooves, more than 40% of the log-producing CWM is generated as sawdust by-product for further processing.
For the first time, combining the sawdust after CWM production from pine wood (Pinus sylvestris) and SA, this study aims to investigate particleboard without hazardous adhesives suitable for cabinet furniture application.
