“…This high concentration of silicon is probably linked to the silica present in the residue, which is solubilized during the alkaline treatment. (Gabriel et al, 2020a). Similar results were observed for açaí (Buratto et al, 2021;Melo et al, 2021) and other lignocellulosic residues (de S. Barros et al, 2020;.…”

“…This behavior is common in several materials and can be observed in cellulose extracted from different agro-industrial waste (Table 4); 2 nd stage was also observed in both samplesaround 180 °C with the highest rate of degradation at 200 °C, related to hemicellulose and cellulose decompositions (Galiwango, Abdel Rahman, Al-Marzouqi, Abu-Omar, & Khaleel, 2019). This result is similar to that found for the degradation of the date palm fiber (180 °C), rose stem (188 °C), and coffee hull with sugarcane bagasse (192 °C) (Gabriel, Belete, Syrowatka, Neubert, & Gebre-Mariam, 2020b;Galiwango et al, 2019;Ventura-Cruz, Flores-Alamo, & Tecante, 2020).…”

“…Several researches are also developed in order to transform this portion into products with added value, such as levulinic acid (Melro et al, 2020), biodiesel (Bhatia et al, 2019;Zhang et al, 2019), and energy generation (Buratto et al, 2021). However, to obtain quality cellulose, the alkaline treatment performed must be highly efficient, since it is at this stage that the cell wall breaks when dissolving the lignin, through the hydrolysis of the esters of acetic and uronic acid and breaks the bonds alpha-ether between lignin and hemicellulose, swelling cellulose (Gabriel et al, 2020a).…”

“…By combining the diffractogram obtained with the registration of 4114994 -ICSD, we confirm that the extracted cellulose presented a semicrystalline structure with characteristics of type I cellulose (TAPPI, 1999). It is important to note the absence of peaks around 29°, normally associated with the presence of mineral impurities such as silica and weddellite (Gabriel et al, 2020a).

“…Another way of using agro-industrial residues that has been very widespread is the extraction of cellulose, a linear homopolymer with a long chain composed of glycosidic bonds with β-D-glucopyranose units (Turner & Kumar, 2018). The cellulose used industrially is usually extracted from trees, such as pine, eucalyptus, and cotton (Gabriel, Belete, Syrowatka, Neubert, & Gebre-Mariam, 2020a). However, the application of these woods in the generation of energy and construction has increased the need to obtain new alternative sources of cellulose, in addition to the growing concern with deforestation.…”

O açaí (Euterpe precatoria Mart.) é uma planta amplamente cultivada na região norte do Brasil. Seus frutos vêm ganhando destaque mundial devido aos inúmeros benefícios para a saúde humana. Consequentemente, a produção de celulose aumentou consideravelmente nos últimos anos, gerando uma quantidade significativa de resíduos (principalmente sementes). Como esses resíduos não têm uma destinação adequada, eles são descartados no meio ambiente ou incinerados, causando inúmeros impactos ambientais. Com o objetivo de apresentar alternativas de aplicação desses resíduos, este trabalho teve como objetivo avaliar o conteúdo lignocelulósico das sementes de açaí - extratos, cinzas, lignina, celulose (α-celulose e hemicelulose) - além de extrair e caracterizar a celulose obtida desse abundante resíduo. As sementes e a celulose extraída foram caracterizadas por diversas técnicas: fluorescência de raios X (XRF), difração de raios X (XRD), refletância total atenuada com espectroscopia de infravermelho por transformada de Fourier (ATR / FTIR) e termogravimetria (TGA). Neste estudo, foi confirmado o alto potencial do uso da semente de açaí como fonte alternativa de celulose, uma vez que apresenta 45,5% desse polímero e todas as técnicas de caracterização mostram a pureza da celulose extraída (tipo I).

In this work, coffee silverskin (CSS) fibers were subjected to alkali pretreatment (ALK‐CSS) and alkali pretreatment, followed by a 4‐bar steam explosion process (SEW4). Both treated fibers presented a higher degree of crystallinity, enhanced thermal resistance and also cleaner, rough, and defibrillated surface due to the removal of noncellulosic components, as was shown in scanning electron microscopy, thermogravimetric analysis, Fourier‐transform infrared spectra, and x‐ray diffraction (XRD) results. The SEW4 fibers were incorporated into the poly(butylene adipate‐co‐terephthalate) (PBAT) matrix in contents up to 5% wt. through melt processing. PBAT/SEW4 composites were evaluated by their microstructure, thermal properties, degree of crystallinity, and hydrophilic behavior. XRD results showed PBAT/SEW4 composites with higher degrees of crystallinity and contact angle tests revealed increased composite hydrophobicity with the increase of SEW4 content in the PBAT matrix. This work describes the importance of recovering coffee lignocellulosic waste and producing value‐added by‐products, especially in packaging manufacturing.

Nowadays, interest in new natural cellulosic materials is increasing due to their higher properties and the motivation for researchers to advance high‐performance bio‐based composites. This study aimed at understanding the physicochemical and morphological properties, crystallinity, and thermal behavior of Borassus flabellifer flower micro‐sized cellulosic fillers. Cellulose has some unique properties, such as good mechanical properties, low density, biocompatibility, thermal stability, and biodegradability. The acid hydrolysis method was used to extract cellulose from the dried B. flabellifer flower. The crystallinity index value and crystalline size were calculated through X‐ray diffraction for the extracted microcrystalline cellulose and found to be 69.81% and 70.73 nm, respectively. The morphology of the extracted cellulosic filler was investigated by scanning electron microscopy and ImageJ software. The average size of the micro filler was found to be 26 μm. The Fourier transform infrared spectroscopy showed the extracted cellulose fillers being free from lignin, hemicelluloses, and other non‐cellulosic materials. Atomic force microscopy revealed that the surface roughness of the cellulose was less than 66 nm. The results showed that an agricultural residue can be converted into a valuable micro‐sized cellulosic filler material for polymeric composite applications that can withstand processing temperature up to 200°C. Here, the naturally occurring source of B. flabellifer flower could be used as a valuable substitute for more traditional sources like wood and cotton for the production of nanocellulose, nano‐additives, or nano‐reinforcing agents for water‐soluble biopolymers.
