Interpretive Summary: Eastern redcedar (ERC) (Juniperus virginiana L., family Cupressaceae) trees may provide a source of bio-materials for engineered wood lumber (i.e., plywood, particleboard, oriented strand board). Currently such products are fabricated using synthetic adhesive resins which contain cancerous formaldehyde. In this study, alternative bio-based adhesives were substituted for synthetic adhesives. Distiller’s dried grains and solubles (DDGS), Osage orange and Soybean flours exhibited good adhesive properties to fabricate fiberboards. These bio-composite had properties sufficient enough to meet Industry strength standards. The commercial employment of these biobased adhesives would result in industrial uses of low value plant-based by-products in the engineered wood manufacturing industries.

Technical Abstract: Bio-based flours derived from Distillers dried grains with solubles (DDGS), Osage orange seed meal (OOSM) or defatted commercial soybean meal flour-Prolia (PRO) were employed as binding resins with Eastern Redcedar (Juniperus virginiana L.) wood (ERC) to fabricate fiberboards. OOSM and DDGS were defatted with hexane, milled and screened prior to use. PRO was employed as provided. DDGS, OOSM or PRO flour were mixed dry with ERC wood to make fiberboards using the following conditions: molding temperature of 185 oC, ERC particle sizes of
