On the other hand, during the last decade, manufacturers of wood-based boards have been facing an acute problem of a shortage of conventional raw materials. The purpose of this study was to evaluate the possibility of using wood particles from deadwood in the production of particleboards. Three-layer particleboards with different content of deadwood particles (0%, 25%, 50%, 75%, 100%) were produced. Conventional urea-formaldehyde (UF) resin was used for gluing the particles. The physical and mechanical properties of the boards, as well as the formaldehyde content in the boards, were determined. In addition, the effect of adding melamine-urea-formaldehyde (MUF) resin to UF adhesive on the properties of the boards was investigated. Replacing conventional sound wood particles with deadwood particles leads to deterioration of the physical and mechanical properties of the boards. The boards from deadwood particles absorb more water and swell more. The bending strength (MOR), modulus of elasticity in bending (MOE), and internal bonding (IB) values for boards with 100% deadwood particles are reduced by 26.5%, 23.1%, and 72.4%, respectively, compared to reference boards from sound wood particles. Despite this, a significant advantage is that boards made from 100% deadwood particles are characterized by 34.5% less formaldehyde content than reference boards made from conventional sound wood. Moreover, adding 3% of MUF resin to UF adhesive increases MOR, MOE, and IB by 44.1%, 43.3%, and 294.4%, respectively.<\/jats:p>","DOI":"10.3390\/polym14173535","type":"journal-article","created":{"date-parts":[[2022,8,29]],"date-time":"2022-08-29T22:53:42Z","timestamp":1661813622000},"page":"3535","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Effects of Wood Particles from Deadwood on the Properties and Formaldehyde Emission of Particleboards"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4320-5247","authenticated-orcid":false,"given":"Pavlo","family":"Bekhta","sequence":"first","affiliation":[{"name":"Department of Wood-Based Composites, Cellulose and Paper, Ukrainian National Forestry University, 79057 Lviv, Ukraine"},{"name":"Department of Wood Science and Technology, Faculty of Forestry and Wood Technology, Mendel University in Brno, Zem\u011bd\u011blsk\u00e1 3, 613 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruslan","family":"Kozak","sequence":"additional","affiliation":[{"name":"Department of Wood-Based Composites, Cellulose and Paper, Ukrainian National Forestry University, 79057 Lviv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladim\u00edr","family":"Gryc","sequence":"additional","affiliation":[{"name":"Department of Wood Science and Technology, Faculty of Forestry and Wood Technology, Mendel University in Brno, Zem\u011bd\u011blsk\u00e1 3, 613 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V\u00e1clav","family":"Sebera","sequence":"additional","affiliation":[{"name":"Department of Wood Science and Technology, Faculty of Forestry and Wood Technology, Mendel University in Brno, Zem\u011bd\u011blsk\u00e1 3, 613 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Tippner","sequence":"additional","affiliation":[{"name":"Department of Wood Science and Technology, Faculty of Forestry and Wood Technology, Mendel University in Brno, Zem\u011bd\u011blsk\u00e1 3, 613 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,28]]},"reference":[{"key":"ref_1","unstructured":"Bobiec, A., Gutowski, J.M., Laudenslayer, W.F., Pawlaczyk, P., and Zub, K.
