The concern about waste in the world is growing because of the significant environmental impact. Therefore, new alternatives are used, such as recycling, biodegradable polymer, agroindustry waste reuse, and many others. In this sense, this paper proposes a production of new bio-packing based on the waste production from agriculture (sugarcane bagasse) and the drinking industry (plastic bottles from Polyethylene Terephthalate (PET)) for agriculture products transportation. Then, this new material was characterized by thermal, chemical, morphological, mechanical, antifungal activity, and hydrophobic character to evaluate its characteristics to use as bio-packing. Following this purpose, all samples are characterized in nature and after production by scanning electron microscopy analysis (SEM), thermogravimetric analysis (TG), infrared spectroscopy analysis (FTIR), surface angle contact, mechanical properties, and antifungal activity. The results indicated that the sample with 15% of bagasse presents the best mechanical properties. In addition, the presence of porosity can provide the material with low thermal conductivity. Moreover, the antifungal activity indicates that inhibition of fungus micellar growth was proportional to the decrease of bagasse in bio-packing. Then, which offers an innovative strategy for the use of waste in the production of environmentally friendly packing.

Background and objective: Despite the situation in the north of Minas Gerais being semiarid, this region presents a plant with low water demand, Calotropis procera. This plant has a great potential as an antifungicide supply, although other important characteristics. In this context, this research proposes an extraction of natural material from C. procera to produce a bio-packing for agriculture and anticorrosive applications as a sustainable alternative. This biopacking is eco-friendly, low-cost, widely available, and quickly produced. The antifungicide and anticorrosive activity were evaluated as the control of fruit ripening based on in vivo tests. Materials and methods: This research is based on the production of bio-packing based on natural extracts from C. procera seeds for agricultural and anticorrosive applications. The material was characterized by Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR) and surface contact angle. In addition, in vitro and in vivo biological experiments were performed to analyze the antifungal activity and control of fruit ripening. Moreover, the anticorrosive property was also analysed. Results: The results indicated the presence of proteins in the composition of the product based on natural extract, which may contribute to the antifungal and anticorrosive characteristics. Furthermore, the natural extract demonstrated anticorrosive protection in simulated seawater. The in vivo analysis of bananas showed that the extract concentration of 50 μL mL-1 presented the best results, controlling the fruit ripening and protecting against diseases. Conclusion: Thus, for the first time, these products extracted from C. procera seeds presented a great future for applications as a versatile action for agriculture and anticorrosive applications.
