The primary goal of this research was to develop a waste protein based adhesive, and to optimize its lap shear strength under dry and wet conditions using Taguchi method. The feedstock for this work was specified risk material (SRM) that is considered the tissue potentially at risk of containing misfolded prions. SRM was hydrolyzed in accordance with government approved techniques and modified with a resin system to develop a renewable adhesive platform. Eight of the nine formulated adhesives met the minimum dry shear strength requirement of urea formaldehyde type adhesive, and three of the formulations also met the soak shear strength requirement. This work demonstrates a general valorization platform for the utilization of animal waste protein as a renewable adhesive feedstock. [ABSTRACT FROM AUTHOR]

The primary goal of this work was to develop a novel adhesive technology platform for oriented strand board (OSB) using waste animal protein extracts, as feedstock. In this research, a hazardous animal processing waste was thermally hydrolyzed, and the proteinaceous fractions were recovered and modified into an adhesive. The adhesive developed as such was formulated for OSB adhesion applications, and the OSB performance was also evaluated. Performance results showed that the OSB specimens made with up to 60% by weight of protein hydrolyzate based adhesive met the Canadian Standard Association (CSA O437.0-93) requirements for commercial applications. Based on the intermediate moisture resistance results observed, the recommended use of these boards could be for relatively low moisture environments. [ABSTRACT FROM AUTHOR]
