The Brazilian açaí industry reached national and international prominence in the last few years. Its final product, mainly frozen pulp, became popular worldwide, accounting for a high market share, including exports. Nevertheless, the solid by-products arising from the processing are not always discarded in an environmentally suitable manner. This review presents a scientometric analysis of açaí research in the last 27 years (1993 to 2019), applying a longitudinal bibliometric study. Through data analysis, it can be observed that Brazil and the USA are the countries that mostly contributed to the development of açaí research. Although Brazil has more publications, the USA presents more articles in partnership with 21 countries. The results also showed that few documents addressed renewable energy recovery with the following technologies: combustion, pyrolysis, supercritical water hydrolysis, and anaerobic digestion. Further analysis of the anaerobic digestion of the totality of açaí seeds generated in Brazil indicated that, theoretically, the electric energy from biogas burning could supply the whole frozen pulp industry requirement with an additional surplus for sales to the grid. Hence, electricity replacement contributes to greenhouse gas mitigation. The assessment of the potential electric energy generation illustrates how technological integration can be an innovative way to rethink the açaí production chain using a circular economy concept. Moreover, the technological advances could stimulate sustainable agro-industrial intensification in areas such as the Legal Amazon, considered a hotspot for climate change mitigation. © 2021 Society of Industrial Chemistry and John Wiley & Sons Ltd.

合法亚马逊的可持续发展:从阿萨伊种子中回收能量

巴西阿萨伊树产业在过去几年中在国内和国际上享有盛誉。其最终产品,主要是冷冻纸浆,在世界范围内广受欢迎,包括出口在内的市场份额很高。然而,加工过程中产生的固体副产品并不总是以适合环境的方式丢弃。本综述采用纵向文献计量研究,对过去 27 年(1993 年至 2019 年)的阿萨伊咖啡研究进行了科学计量分析。通过数据分析可以看出,巴西和美国是对阿萨伊研究发展贡献最大的国家。尽管巴西有更多的出版物,但美国与 21 个国家合作发表了更多的文章。结果还表明,很少有文件涉及使用以下技术进行可再生能源回收:燃烧、热解、超临界水水解和厌氧消化。对巴西产生的全部阿萨伊种子厌氧消化的进一步分析表明,从理论上讲,沼气燃烧产生的电能可以满足整个冷冻纸浆行业的需求,并有额外的盈余用于向电网销售。因此,电力替代有助于减缓温室气体排放。对潜在发电量的评估说明了技术整合如何成为使用循环经济概念重新思考阿萨伊生产链的创新方式。此外,技术进步可以刺激合法亚马逊等地区的可持续农业工业集约化,被认为是缓解气候变化的热点。
