Abstract

The present research aimed to obtain a bioplastic made of Manihot esculenta (cassava) and Ficus benjamina. For this purpose, the residual lignocellulose of Ficus benjamina was mechanically conditioned until obtaining a particle size lower than 180 µm. There were elaborated samples of cassava starch bioplastic as blank test (BPY) and samples of cassava starch bioplastic with lignocellulose proportions of 12.59% (BPL5), 17.65% (BPL6) and 22.22% (BPL7). The average results of tensile strength evaluation of the BPY, BPL5, BPL6 and BPL7 samples were 9.9, 14.6, 14.8 and 15.7 Kpa, respectively. The BPY sample provided a higher elongation percentage with an average value of 13.59%. As for the biodegradation by gravimetric method for 5, 10 and 20 days, better results were evidenced for the BPL7 sample, with percentages of weight loss of 17.45, 27.08 and 48.69%, respectively. Finally, it is concluded that the bioplastic based on cassava and Ficus benjamina could be established as a favorable ecological alternative to be used in food products due to its good properties of resistance and favorable biodegradation.

由木薯和榕树制成的生物塑料作为食品的生态替代品

本研究以木薯和榕树为原料制备生物塑料。为此，对本雅明榕树的残留木质纤维素进行机械调理，直到获得小于180µm的粒径。制备的木薯淀粉生物塑料样品分别为空白样品(BPY)和木质纤维素比例分别为12.59% (BPL5)、17.65% (BPL6)和22.22% (BPL7)的木薯淀粉生物塑料样品。BPY、BPL5、BPL6和BPL7试样的抗拉强度评估平均结果分别为9.9、14.6、14.8和15.7 Kpa。BPY样品的伸长率较高，平均为13.59%。重量法降解5、10和20 d时，BPL7样品的生物降解效果较好，失重率分别为17.45%、27.08和48.69%。最后得出结论，木薯和榕树生物塑料具有良好的耐药性能和良好的生物降解性能，可作为一种良好的食品生态替代品。

期刊介绍： Chemical Engineering Transactions (CET) aims to be a leading international journal for publication of original research and review articles in chemical, process, and environmental engineering. CET begin in 2002 as a vehicle for publication of high-quality papers in chemical engineering, connected with leading international conferences. In 2014, CET opened a new era as an internationally-recognised journal. Articles containing original research results, covering any aspect from molecular phenomena through to industrial case studies and design, with a strong influence of chemical engineering methodologies and ethos are particularly welcome. We encourage state-of-the-art contributions relating to the future of industrial processing, sustainable design, as well as transdisciplinary research that goes beyond the conventional bounds of chemical engineering. Short reviews on hot topics, emerging technologies, and other areas of high interest should highlight unsolved challenges and provide clear directions for future research. The journal publishes periodically with approximately 6 volumes per year. Core topic areas: -Batch processing- Biotechnology- Circular economy and integration- Environmental engineering- Fluid flow and fluid mechanics- Green materials and processing- Heat and mass transfer- Innovation engineering- Life cycle analysis and optimisation- Modelling and simulation- Operations and supply chain management- Particle technology- Process dynamics, flexibility, and control- Process integration and design- Process intensification and optimisation- Process safety- Product development- Reaction engineering- Renewable energy- Separation processes- Smart industry, city, and agriculture- Sustainability- Systems engineering- Thermodynamic- Waste minimisation, processing and management- Water and wastewater engineering
