Practical properties and formaldehyde emission of medium density fiberboards (MDFs) recycled by electrical method, Bita Moezzipour et al , European Journal of Wood and Wood Products , online. In this study, the performance of the electrical method in MDF waste recycling was determined. For investigating the practical aspect of the electrical method, the hydrothermal method as a known recycling method was studied too. The results of this study confirmed the positive effect of recycled fibers on reducing the formaldehyde emission from MDF boards which can be considered as an excellent benefit for the recycling process due to the importance of environmental and human health issues. Recovering fibres from fibreboards for wood polymer composites production, F. Yağmur Bütün et al , International Wood Products Journal , online. In most countries, fibreboards are not recovered after utilization but burned for energy production. This study aims at recovering fibres from industrial fibreboards and reusing them as reinforcement elements in wood polymer composites (WPC). The study indicates that recovered fibres are suitable to produce WPC with very similar physico-mechanical properties as those from ‘virgin’ fibres. All Natural High-Density Fiber- and Particleboards from Hemp Fibers or Rice Husk Particles, Daniele Battegazzore et al , Journal of Polymers and the Environment , Vol.26 (4). In the present study, long hemp fibres and rice husk particles have been used for producing all natural-based boards for building, automotive and in-door furniture, employing a simple and economic transformation process (namely, compression moulding). In order to have the required consistence and mechanical strength, corn starch was employed as binder. By this way, fibre- and particleboards have been prepared and characterized in terms of morphology, mechanical properties (flexural modulus and strength). Improving Water Resistance of Soy-Based Adhesive by Vegetable Tannin, Saman Ghahri et al , Journal of Polymers and the Environment , Vol.26 (5). In this research tannic acid was used to prepare soy-based adhesives for making plywood and fibre board. The different resin formulations were analysed. Overall, the mechanical and physical properties such as MOR, MOE, IB, and water resistance of fibreboard were improved, by adding tannic acid to the soy-based adhesive. Investigating the interaction between internal structural changes and water sorption of MDF and OSB using X-ray computed tomography, Wanzhao Li et al , Wood Science and Technology , Vol.52 (3). Both medium density fibreboard (MDF) and oriented strand board (OSB) are increasingly used in construction, yet when exposed, water sorption can cause internal structural changes, as such decreasing mechanical strength and increasing decay risk. It is, therefore, essential to understand the interaction between structural changes and water sorption of MDF and OSB. This article makes a detailed study of physical changes caused by water sorption.
