From waste to resource: technologies for the sustainable use of açaí (Euterpe oleracea) byproducts

The rapid expansion of the global açaí (Euterpe oleracea) market has led to an alarming increase in waste generation, particularly seeds and fibers, posing significant environmental challenges. This review explores innovative strategies to repurpose these residues through cutting-edge technologies, including nanotechnology for nanocellulose production, microbial fermentation for biopolymer synthesis, and green extraction methods for obtaining bioactive compounds. Emphasis is placed on the development of high-value-added products such as biodegradable plastics, biomaterials, and renewable energy sources, aligning with the principles of the circular economy. Additionally, the review highlights the socioeconomic potential of these innovations and their role in mitigating environmental impacts. A focus is given to the need for sustainable practices and policy-driven initiatives to maximize the value of açaí residues, calling for solutions to overcome technological and economic barriers while promoting sustainable development in the Amazon region.
