Bioplastic Made from Manihot Esculenta (cassava) and Ficus Benjamina as an Ecological Alternative for Food Products
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.
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
