  Brazil is one of the main producers of agricultural products, however, the industrial processing of these fruits and vegetables also generates significant amounts of waste that may cause environmental impacts, such as an increase in greenhouse gases emissions and water pollution. In this context, this study investigates the feasibility of producing bacterial cellulose (BC) from passion fruit peel (Passiflora edulis), an abundant agro-industrial co-product. The peel underwent acid hydrolysis, which yielded 9.98 g/L of glucose and 19.03 g/L of xylose. These sugars were used as carbon sources for fermentation using a symbiotic culture of bacteria and yeast (SCOBY) derived from kombucha production. The process resulted in the production of 6.064 g of purified BC. The material suggests promising physical and chemical properties, with potential applications in adsorption processes, such as removing heavy metals, industrial dyes, and organic contaminants from wastewater. However, further experiments are needed to fully evaluate its effectiveness in these applications. This research suggests that utilizing agro-industrial waste like passion fruit peel adds value to these by-products, promotes sustainable practices, and supports the circular economy.
