Molded plywood is made with urea-formaldehyde (UF) adhesives; therefore, the issue of the fillers used in them is important. The potential of using ground beech (Fagus sylvatica L.) bark as an eco-friendly additive in UF adhesives for molded plywood manufacturing was investigated in this work. Wheat flour was used as a reference filler. The beech bark (BB) level as a filler was 10%, a value verified under laboratory conditions. Nine-layer flat and molded plywood were produced under industrial conditions from beech veneers bonded with a UF adhesive mixture. The mechanical (bending strength and bonding quality) and physical (swelling and absorbency values after 2 and 24 h) properties of the industrially fabricated molded plywood were evaluated and compared with the European standard requirements (EN 310 and EN 314-2). The mechanical properties of the molded plywood with the addition of BB in the adhesive mixture were acceptable and met these standards\u2019 requirements. The positive effect of BB in the UF adhesive mixture on a reduction in formaldehyde emissions from the molded plywood was also confirmed. BB, considered to be wood-processing industry waste or a by-product, has significant potential to be used as a filler in UF resins for molded plywood production, providing an environmentally friendly, inexpensive solution for the industrial valorization of bark as a bio-based formaldehyde scavenger.<\/jats:p>","DOI":"10.3390\/polym16070966","type":"journal-article","created":{"date-parts":[[2024,4,3]],"date-time":"2024-04-03T00:58:38Z","timestamp":1712105918000},"page":"966","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Molded Plywood with Proportions of Beech Bark in Adhesive Mixtures: Production on an Industrial Scale"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7983-4045","authenticated-orcid":false,"given":"Roman","family":"Reh","sequence":"first","affiliation":[{"name":"Faculty of Wood Science and Technology, Technical University in Zvolen, 96001 Zvolen, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2385-5760","authenticated-orcid":false,"given":"Lubos","family":"Kristak","sequence":"additional","affiliation":[{"name":"Faculty of Wood Science and Technology, Technical University in Zvolen, 96001 Zvolen, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Sedliacik","sequence":"additional","affiliation":[{"name":"Faculty of Wood Science and Technology, Technical University in Zvolen, 96001 Zvolen, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavlo","family":"Bekhta","sequence":"additional","affiliation":[{"name":"Faculty of Wood Science and Technology, Technical University in Zvolen, 96001 Zvolen, Slovakia"},{"name":"Department of Wood-Based Composites, Cellulose and Paper, Ukrainian National Forestry University, 79057 Lviv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1269-5367","authenticated-orcid":false,"given":"Anita","family":"Wronka","sequence":"additional","affiliation":[{"name":"Institute of Wood Sciences and Furniture, Warsaw University of Life Sciences, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1463-0540","authenticated-orcid":false,"given":"Grzegorz","family":"Kowaluk","sequence":"additional","affiliation":[{"name":"Institute of Wood Sciences and Furniture, Warsaw University of Life Sciences, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,2]]},"reference":[{"key":"ref_1","unstructured":"Youngquist, J.A.
