“…Figure 3A showed a combustion process, presenting the occurrence of four main mass loss events. The first one occurs in the range of 30 to 130 °C and corresponds to approximately 6.5% of mass loss associated to moisture release (VARMA & MONDAL, 2017;REIS et al, 2019). The second event is evidenciated by a more expressive mass loss of 62%, showed Correia et al by DTG between 130 to 350 °C, associated to the degradation of hemicellulose, part of cellulose and lignin.…”

“…The thermal behavior of biomass of PAS was evaluated using thermogravimetric analysis. The TG curve represents the changes in mass related to the increase in temperature, while the DTG curve represents the loss of mass that occurs as a function of temperature (REIS et al, 2019). Figure 3A showed a combustion process, presenting the occurrence of four main mass loss events.…”

“…The second event is evidenciated by a more expressive mass loss of 62%, showed Correia et al by DTG between 130 to 350 °C, associated to the degradation of hemicellulose, part of cellulose and lignin. Hemicellulose is a compound that presents low thermal stability when compared to cellulose and lignin, and commonly decomposes under temperatures in the range of 220 to 315 °C (VARMA & MONDAL, 2017;REIS et al, 2019;CALIXTO et al, 2021). The third occurs between 350 and 450 °C, associated to the thermal degradation of cellulose with 23% of mass loss.…”

“…The third occurs between 350 and 450 °C, associated to the thermal degradation of cellulose with 23% of mass loss. The cellulose presents a complete degradation in the range of 280 to 360 °C, and it is more stable than the hemicellulose due to the presence of hydrogen bonds, which promote a strong interaction between the cellulose chain (VARMA & MONDAL, 2017;SILVA et al, 2018;REIS et al, 2019). The last event is defined by the decomposition of lignin, which occurs slowly, overlapping the other events due to the polyaromatic characteristic of this component.…”

This research valorized Pachira aquatica Aubl.’s fruit shells (PAS) through its energetic characterization and flash pyrolysis for biofuels or chemicals production. The characterization was performed through proximate and ultimate analysis, bulk density, higher heating value (HHV), hemicellulose, cellulose and lignin content, thermogravimetric analysis and absorption spectra in the infrared region obtained by Fourier-transform infrared spectroscopy technique (FTIR). The analytical flash pyrolysis was performed at 500°C in a Py-5200 HP-R coupled to a gas chromatograph (Py-GC/MS). The PAS biomass presents potential for thermochemical energy conversion processes due to its low moisture and ash content, 76.90% of volatile matter, bulk density of 252.6 kg/m3 and HHV of 16.24 MJ/kg. Flash pyrolysis products are mostly phenols or light organic acids derived from the decomposition of polysaccharides. Results confirmed the potential of PAS to produce bio-phenolics, such as 4-methoxyphenol which is an important active ingredient for skin depigmentation used in drugs and cosmetics, and as phenolic extract that can be used as a precursor to resins, applications that convert this forest waste into bio products for industry into a green circular economy.

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.
