| description | Adhesives are significant for manufacturing competent, light, and sturdy goods in various industries. Adhesives are an important part of the modern manufacturing landscape because of their versatility, cost-effectiveness, and ability to enhance product performance. Formaldehyde and polymeric diphenylmethane diisocyanate (PMDI) are conventional adhesives utilized in wood applications and have been classified as carcinogenic, toxic, and unsustainable. Given the adverse environmental and health effects associated with synthetic adhesives, there is a growing research interest aimed at developing environmentally friendly bio-based wood adhesives derived from renewable resources. This study aimed to extract starch from <i>camote</i> and cassava peels and focuses on the oxidization of starch derived from <i>camote</i> and cassava peels using sodium hypochlorite to create bio-based adhesives. The mean yield of starch extracted from <i>camote</i> and cassava peels was 13.19 ± 0.48% and 18.92 ± 0.15%, respectively, while the mean weight of the oxidized starches was 34.80 g and 45.34 g for camote and cassava, respectively. Various starch ratios sourced from <i>camote</i> and cassava peels were examined in the production of bio-based adhesives. The results indicate that the 40:60 <i>camote</i> to cassava ratio yielded the highest solid content, while the 80:20 ratio resulted in the best viscosity. Furthermore, the 40:60 ratio produced the most favorable particle board in terms of mechanical properties, density, thickness, swelling, and water absorption. Consequently, the starch extracted from <i>camote</i> and cassava peels holds promise as a potential source for bio-based adhesives following appropriate chemical modification. |
