The recycling and utilization of feather waste from animal husbandry and straw from agriculture is a worldwide problem. In this study, keratin was extracted from waste feathers and used to modify urea-formaldehyde (UF) adhesive to obtain biodegradable adhesive for making straw flowerpots with high performance. The results showed that keratin could reduce free formaldehyde and improve the thermal stability of UF. Furthermore, the mechanical properties of the flowerpot with keratin were greatly improved. The observed performance enhancements were attributed to the excellent adhesiveness of the bonding interface. In addition, the addition of keratin makes the flowerpot more hydrophilic and provides a better source of nutrients for microbes to grow and reproduce on the surface of the flowerpot, which is more conducive to the biodegradation of flowerpots after they are discarded. Our experiment suggests the great potential in terms of profitability and environmental protection by flowerpots prepared by fermented straw fiber and keratin-modified UF.

发酵秸秆纤维和废羽毛角蛋白改性脲醛胶制备新型可降解花盆

畜牧业羽毛废料和农业秸秆的回收利用是一个世界性难题。在本研究中，从废羽毛中提取角蛋白并用于改性脲醛（UF）粘合剂，以获得可生物降解的粘合剂，用于制造高性能的稻草花盆。结果表明，角蛋白可以减少游离甲醛，提高超滤的热稳定性。此外，带有角蛋白的花盆的机械性能得到了极大的改善。观察到的性能增强归因于粘合界面的优异粘合性。此外，角蛋白的加入使花盆更具亲水性，为微生物在花盆表面生长繁殖提供了更好的营养来源，这样更有利于花盆丢弃后的生物降解。我们的实验表明，由发酵秸秆纤维和角蛋白改性超滤制备的花盆在盈利能力和环境保护方面具有巨大潜力。
