“…A pineapple plant in the harvested state contains 25 to 30 leaves, with diameters ranging from 45 µm to 205 µm. These leaves contain 2% to 3% fiber and are composed of approximately 70-80% cellulose, 17% hemicellulose, and 5% lignin [21].…”

Cellulose nanofiber is the world’s most advanced biomass material. Most importantly, it is biodegradable. In this work, nanofibers were obtained from pineapple leaves, a large solid waste in Colombia, using a combined extraction method (chemical procedures and ultrasound). The native fibers were bleached, hydrolyzed, treated with ultrasound, and characterized by scanning electron microscopy (SEM), infrared analysis (FTIR), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM). As a comparison, a commercial microcrystalline cellulose sample was analyzed, which demonstrated the efficiency of cellulose extraction. The nanofibers had a diameter and a length of 18 nm and 237 nm, respectively, with a maximum degradation temperature of 306 °C. The analysis showed the efficiency of acid treatment combined with ultrasound to obtain nanofibers and confirmed that pineapple residues can be valorized by this method. These results indicate that lignocellulosic matrices from pineapple leaves have potential application for obtaining polymeric-type composite materials. Due to their morphology and characteristic physical properties, the cellulose nanofibers obtained in this work could be a promising material for use in a wealth of fields and applications such as filter material, high gas barrier packaging material, electronic devices, foods, medicine, construction, cosmetics, pharmacy, and health care, among others.

“…In this process, water at subcritical temperature acts as an acid and results in significant changes in the lignocellulosic biomass, thereby enhancing subsequent enzymatic hydrolysis. Many previous reports on the use of hydrothermal pretreatment of lignocellulosic wastes have employed externally added catalysts such as acids or bases [ 15 , 16 ], which makes such studies less environmentally friendly.…”

Being a lignocellulose-rich biomass, pineapple leaves waste (PL) could be a potential raw material for the production of biofuel, biochemicals, and other value-added products. The main aim of this study was to investigate the potential of pineapple leaves in the sustainable production of bioethanol via stepwise saccharification and fermentation. For this purpose, PL was subjected to hydrothermal pretreatment in a high-pressure reactor at 150 °C for 20 min without any catalyst, resulting in a maximum reducing sugar yield of 38.1 g/L in the liquid fraction after solid-liquid separation of the pretreated hydrolysate. Inhibitors (phenolics, furans) and oligomers production were also monitored during the pretreatment in the liquid fraction of pretreated PL. Enzymatic hydrolysis (EH) of both pretreated biomass slurry and cellulose-rich solid fraction maintained at a solid loading (dry basis) of 5% wt. was performed at 50 °C and 150 rpm using commercial cellulase at an enzyme dose of 10 FPU/gds. EH resulted in a glucose yield of 13.7 and 18.4 g/L from pretreated slurry and solid fractions, respectively. Fermentation of the sugar syrup obtained by EH of pretreated slurry and the solid fraction was performed at 30 °C for 72 h using Saccharomyces cerevisiae WLP300, resulting in significant ethanol production with more than 91% fermentation efficiency. This study reveals the potential of pineapple leaves waste for biorefinery application, and the role of inhibitors in the overall efficiency of the process when using whole biomass slurry as a substrate.

“…They reported that 0.5% NaOH gave a higher glucose yield compared with H2SO4 dilute and hot water treatment. Nashiruddin et al (2020) conducted a research to determine the effect of pyrolysis parameters (NaOH (0.5%, 80°C, 60 min), H2SO4 (0.5 %, 80°C, 60 min) and hot water (100°C for 90 min) on the formation of reducing sugar from pineapple leaves fiber. The authors reported that treatment with NaOH yielded the highest reducing sugar.…”

“…However, its recalcitrant nature is the main bottleneck to overcome in the enzymatic hydrolysis of lignocellulosic biomass, necessitating the pre-treatment prior to fermentation to make it more accessible to cellulolytic enzymes (Zoghlami and Paës, 2019). There are numerous pre-treatment techniques available, of which pre-treatment with NaOH and H2SO4 have been widely investigated (Nashiruddin et al, 2020). Distinctive features of Miscanthus giganteus, such as high yield, high cellulose content and low input requirements as well as the possibility to harvest twice a year make it an ideal energy crop for bioethanol production.…”
