Macaúba’s world scenario: a bibliometric analysis

Abstract

Macaúba is a tropical palm native in South and Central America, and its fruits present a high-quality oil for biodiesel production. Notwithstanding, macaúba's wastes and by-products are not usually repurposed as energy sources. This study shows a bibliometric analysis to assess macaúba's current applications and to investigate other energy recovery routes for its by-products. All the investigations focused on information about the main research fields related to macaúba. The study showed that only 397 articles and reviews were published from 1900 until 2021, and Brazil is the leading publisher. Although oleic and protein macaúba's by-products are applied as animal feed, some conversion routes related to the lignocellulosic contents, present in non-edible parts, were identified thermal conversion, combustion, gasification, pyrolysis, biochemical conversion, fermentation, esterification, and anaerobic digestion.From the agricultural perspective, plant characterization, germination, embryogenesis, and seed development were also found. From the bibliometric study, the different potential applications of macaúba for energy, pharmaceutical, and food purposes were listed to support the identification of a knowledge gap on its by-products revaluation.

Acrocomia spp.: neglected crop, ballyhooed multipurpose palm or fit for the bioeconomy? A review

“…With this goal in mind, we developed a systematic literature review with a detailed categorization of publications and a deep analysis and structuring of findings. In this way, our novel approach adds further information and reveals key research gaps, complementing other reviews on specific topics (de Lima et al 2018), non-systematic reviews (Hernández 2016), and bibliometric studies (Ampese et al 2021). The main objective of this review is thus to provide readers with the state-of-the-art of acrocomia research by evaluating the past four decades of published literature and to systematically identify progress and obstacles in implementing acrocomia as a sustainable, alternative multipurpose crop in Latin America.…”

A bibliometric analysis on potential uses of brewer's spent grains in a biorefinery for the circular economy transition of the beer industry

“…[10][11][12] Bibliometric tools can be used to perform a complete analysis of scientific publications related to a subject area. 13,14 This systematic method can support the analysis of emerging trends, addressing gaps, and identifying all the collaboration networks of the research area. 13 Moreover, the bibliometric analysis identifies the possible knowledge gaps and supports the establishment of future studies to better understand the state of the art of a research field.…”

Sustainable valorization of apple waste in a biorefinery: a bibliometric analysis

“…The global intensification and worldwide demand for processed food products have led to a high generation of solid and liquid wastes by the industrial sectors 1 . Typically, these wastes consist of liquid effluents and solid residues with high chemical oxygen demand and biodegradability 2 .…”
