SUMMARY:

Research has shown that passion fruit production is approximately 700,000 tons per year in an area of 46,000 hectares, representing 70% of world production, making Brazil the world's largest producer and consumer of passion fruit (Passiflora edulis f. flavicarpa). However, as the largest consumer of the fruit, environmental impact is inevitable, resulting in the improper disposal of passion fruit waste, especially the peels. In this context, biotechnological strategies have been applied, aiming to transform passion fruit peel waste into raw material for the creation and development of biopolymers, as a promising and sustainable solution to mitigate environmental pollution. In this sense, initial studies were directed at bioplastics that were developed from yellow passion fruit peels (Passiflora edulis f. flavicarpa), associated with cassava starch and glycerol, using casting and evaporation methods to form films. The physical-chemical characterization of the produced material included analyses of solubility in water and different organic solvents, mechanical tensile strength, elongation and structural analysis, using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) revealed a rough surface, presenting small pores. In the solubility test, the bioplastic was insoluble in water and organic solvents, although it absorbed a lot of water, making it the most suitable use in packaging for dry products. The mechanical properties confirm the potential application of these bioplastics as a replacement for synthetic polymers, especially in sectors that require low-cost materials and eliminate environmental impact and allow the generation of a patent. Continuing, improvements are necessary to strengthen the bioplastic and new strategies are being used with passion fruit peels to create and develop vegetable leather in association with vegetable latex, thus demonstrating through the circular bioeconomy the possibility of diverse applications with environmental waste, in addition to promoting the reduction of environmental impact. It is also worth noting that the activities developed and under development meet the 2030 Agenda, promoting sustainable development, with a focus on industry, innovation and infrastructure (SDG 9), sustainable cities and communities (SDG 11) and responsible consumption and production (SDG 12). Therefore, the promising advances presented also highlight the forecast of using agricultural by-products in the development of innovative and sustainable biomaterials, consolidating viable alternatives for the packaging market, vegetable leather and other industrial sectors.
