The conventional particleboard industry relies on synthetic, predominantly formaldehyde-based adhesives, which pose environmental, health, and end-use risks. Rising raw material prices, regulatory restrictions, and increasing competition in the wood-processing sector have further highlighted the importance of alternative biomass resources for particleboard production. In response to these challenges, this study investigates the suitability of available sawdust resources derived from the production residues of cellular wood materials and recycled particleboards, combined with natural suberinic acids mixture obtained from birch outer bark as a binder. The effects of furnish structure, binder content (15\u201321%), pressing temperature (190\u2013220 \u00b0C), pressing rate (0.9\u20131.7 min\/mm), and board density (650\u2013850 kg\/m3) on the resulting particleboard properties were evaluated. The results demonstrate that it is possible to meet the requirement values for thickness swelling (\u226417%) and internal bonding strength (\u22650.40 N\/mm2) specified for interior fitment boards, including furniture applications according to EN 312, Type P2. The bending properties of the best-performing particleboards are very close to the requirement values (MOE \u2265 1800 N\/mm2, MOR \u2265 11 N\/mm2), indicating the potential for further improvement at the target density range. Furnish structure, board thickness, density, and pressing temperature were identified as the most influential factors affecting the final board properties.<\/jats:p>","DOI":"10.3390\/polym18040487","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T14:09:54Z","timestamp":1771250994000},"page":"487","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Development of Suberinic Acids-Bonded Medium-Density Particleboard"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5172-1946","authenticated-orcid":false,"given":"Ramunas","family":"Tupciauskas","sequence":"first","affiliation":[{"name":"Laboratory of Biorefinery, Latvian State Institute of Wood Chemistry, Dzerbenes 27, 1006 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andris","family":"Berzins","sequence":"additional","affiliation":[{"name":"Laboratory of Biorefinery, Latvian State Institute of Wood Chemistry, Dzerbenes 27, 1006 Riga, Latvia"},{"name":"Faculty of Forest and Environmental Sciences, Latvia University of Life Sciences and Technologies, Akademijas 11, 3001 Jelgava, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gunars","family":"Pavlovics","sequence":"additional","affiliation":[{"name":"Laboratory of Biorefinery, Latvian State Institute of Wood Chemistry, Dzerbenes 27, 1006 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-0410-5178","authenticated-orcid":false,"given":"Rudolfs","family":"Berzins","sequence":"additional","affiliation":[{"name":"Laboratory of Biorefinery, Latvian State Institute of Wood Chemistry, Dzerbenes 27, 1006 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martins","family":"Andzs","sequence":"additional","affiliation":[{"name":"Laboratory of Biorefinery, Latvian State Institute of Wood Chemistry, Dzerbenes 27, 1006 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4825-3053","authenticated-orcid":false,"given":"Janis","family":"Rizikovs","sequence":"additional","affiliation":[{"name":"Laboratory of Biorefinery, Latvian State Institute of Wood Chemistry, Dzerbenes 27, 1006 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,14]]},"reference":[{"key":"ref_1","unstructured":"FAOSTAT (2025, November 26).
