Use of Agro-Industrial Biomasses as a Strategy to Increase the Sustainable Bioeconomy in the Amazon

Biomasses from agro-industrial practices in the Amazon have generated significant inputs in the last decade for the development of projects and the extension of more sustainable production chains, based on the results of research on both laboratory and pilot scales, and from the rapid expansion in industrial scaling. The rise in the use of biomass includes the use of raw materials from so-called superfruits, notable examples of which include açaí (Euterpe oleracea Mart.), Brazil nut (Bertholletia excelsa HBK), pupunha (Bactris gasipaes Kunth), tucumã (Astrocaryum aculeatum) and buriti (Mauritia flexuosa). All of these are of great importance to the trade balance of the Amazon region, contributing significantly to the import of products and by-products from Brazil. In view of the above, this research aims to present the nutritional, functional and technological properties of these biomasses as a contribution to industrial innovation in the use of isolated constituents in various segments of the food, pharmaceutical, dermocosmetic and packaging industries. The data show that research into the protein, fibrous and starch-based biopolymers contained in these biomasses has been guided and deepened, with an emphasis on investigations in isolation and on applications of bioactive compounds and starches and fibers in the development of films and packaging with good resistance properties and high environmental biodegradability, these being economically viable as food coatings, acting in synergy with the application of technologies and the increase in the sustainable circular bioeconomy in the Amazon, combining techno-economic and environmental development in the most diverse industrial sectors.
