| Abstract | This study explores the production of biodegradable insulation panels from waterhyacinth fibers using urea–formaldehyde (UF) and natural latex binders, supporting Thailand’sBio-Circular-Green (BCG) Economy model. Panels were hot-pressed at resin-to-fiber ratiosof 33.5:66.5, 50.0:50.0, and 66.5:33.5, and evaluated according to ASTM and EN standards.Latex-bonded panels exhibited thermal conductivity of 0.0628–0.0748 W/m·K as measuredby ASTM C518, meeting typical building insulation material standards (<0.08 W/m·K) andperforming comparably to other bio-based insulation materials. Optimal formulations showedthickness swelling below 12% (EN 622-4 compliant, tested according to EN 317), whilewater absorption reached up to 185%, a limitation that can be addressed by surface treatment.Compared with UF boards, latex panels showed improved dimensional stability and moistureresistance while remaining entirely formaldehyde-free. These findings suggest latex-bondedwater hyacinth panels to be a sustainable alternative for indoor insulation in residential andpublic buildings where indoor air quality is a priority. With bulk densities ranging from 470 to705 kg/m³, the panels can be effectively utilized as ceiling and wall insulation materials. Byvalorizing renewable biomass and employing bio-based adhesives, this approach advances theBCG model and contributes to the United Nations Sustainable Development Goals (SDGs),including SDG 3 (Health), SDG 9 (Innovation), SDG 12 (Responsible Production), and SDG13 (Climate Action). |
