The bioplastics sector promotes environmentally friendly means of cutting down on the usage of fossil fuels, plastic waste, and environmental pollution. Plastic contamination has detrimental effects on both ecological systems and the global food supply. The approach we present here to resolve this issue involves the integration of sericin and gelatin, obtained from cocoon and fish waste, respectively, with nano-reinforced cellulose crystals, to develop a biodegradable and compostable plastic material. The use of cocoon and fish wastes for the extraction of sericin and gelatin presents an environmentally beneficial approach since it contributes to waste reduction. The sericin level found in silk cocoon waste was determined to be 28.08%, and the gelatin amount in fish waste was measured to be 58.25%. The inclusion of sericin and gelatin in bioplastics was accompanied by the incorporation of glycerol, vinegar, starch, sodium hydroxide, and other coloring agents. Fourier transform infrared (FTIR) examination of bioplastics revealed the presence of functional groups that corresponded to the sericin and gelatin components. The tensile strength of the bioplastic material was measured to be 27.64 MPa/psi, while its thickness varied between 0.072 and 0.316 mm. The results of burial experiments indicated that the bioplastic material had a degradation rate of 85% after 14 days. The invention exhibits potential as a viable alternative for packaging, containment, and disposable plastic materials. The use of this sustainable approach is recommended for the extraction of sericin and gelatin from silk cocoons and fish waste, with the intention of using them as raw materials for bioplastic production.
生物塑料行业推广环保方式，以减少化石燃料的使用、塑料垃圾和环境污染。塑料污染对生态系统和全球食品供应都有不利影响。我们在此提出的解决这一问题的方法是，将分别从蚕茧和鱼废料中提取的丝胶蛋白和明胶与纳米增强纤维素晶体相结合，以开发一种可生物降解和可堆肥的塑料材料。利用蚕茧和鱼废料提取丝胶蛋白和明胶是一种对环境有益的方法，因为它有助于减少废物。经测定，蚕茧废料中的丝胶蛋白含量为28.08%，鱼废料中的明胶含量为58.25%。在生物塑料中加入丝胶蛋白和明胶的同时，还加入了甘油、醋、淀粉、氢氧化钠和其他着色剂。对生物塑料进行的傅里叶变换红外光谱（FTIR）检测显示存在与丝胶蛋白和明胶成分相对应的官能团。该生物塑料材料的拉伸强度测得为27.64兆帕斯卡/磅力每平方英寸，其厚度在0.072至0.316毫米之间变化。掩埋实验结果表明，该生物塑料材料在14天后的降解率为85%。本发明具有作为包装、容器和一次性塑料材料的可行替代品的潜力。建议采用这种可持续方法从蚕茧和鱼废料中提取丝胶蛋白和明胶，以便将它们用作生物塑料生产的原材料。
