“…The cellulose, hemicelluloses and lignin contents of dried BCR were 44·3 ± 5·5%, 20·5 ± 3·0% and 16·3 ± 2·6% respectively (Table ). The pseudo‐stem part contained a good amount of cellulose ( c. 60–65%) and less amount of hemicellulose (10–15%) (Shimizu et al ; Srivastava et al ). In this work, the cellulose content of BCR was low because it’s leaf contained low amounts of cellulose and high amount of hemicellulose and lignin when compared with the pseudo‐stem.…”

“…In India, presently this waste biomass is almost being dumped to roadside, burnt or left in situ causing a detrimental effect on the environment. Although techniques for extraction of fibres and papers from pseudo‐stem are available, they have not been widely adopted by industries mainly due to their bulky nature leading to a high transport cost (Cardeiro et al ; Srivastava et al ). In recent years, researchers investigated the pretreatment, hydrolysis and ethanol production from banana pseudo‐stem (Reddy et al ; Santa‐Maria et al ; Gabhabe et al ; Ingale et al ; Kamdem et al ; Guerrero et al ).…”

“…It is the first largest producer in the world. The area under banana cultivation is around 800 000 ha with 27·5 MMT production during 2012–2013 (Srivastava et al ). In India, Maharashtra, Gujarat, Tamil Nadu, Andhra Pradesh, Karnataka and Kerala are the leading states in banana cultivation.…”

This study aimed to produce acetone‐butanol‐ethanol (ABE) using lignocellulosic crop residues as renewable bioresources. Butanol production from banana crop residue (BCR) was studied using a newly isolated solventogenic Clostridium beijerinckii YVU1. BCR is one of the abundant lignocellulosic substrates available in tropical countries containing 4·3 ± 3·5% cellulose, 28·5 ± 3·0% hemicellulose and 20·3 ± 2·6% lignin. The sequential dilute alkali and acid pretreatments solubilized 69% of lignin and 73% of hemicellulose. Ten percent (w/v) of pretreated substrate was subjected to enzymatic saccharification with cellulase, and it was found to release 0·481 ± 0·035 g glucose per g pretreated biomass. In the batch fermentation process, 20·5 g l−1 ABE (14·0 g l−1 of butanol, 5·4 g l−1 of acetone and 1·1 g l−1 of ethanol) was obtained. The executed fermentation process yielded 0·39 g ABE per g hydrolysate with 0·14 g l−1 h−1 of volumetric productivity. On the basis of the results, we believe that sequential alkali and acid pretreatment on the enzymatic hydrolysis for butanol production is indeed a technology with the potential to be applied and newly isolated. C. beijerinckii YVU1 is also a potential candidate organism for butanol production agricultural residues. Significance and Impact of the Study This study demonstrates that a banana crop residue (BCR) can be successfully utilized as an inexpensive and alternative bioresource for the production of acetone‐butanol‐ethanol (ABE). The sequential pretreatment of BCR with alkali and acid solubilized lignin and hemicellulose leading to high glucose release during enzymatic hydrolysis. A newly isolated Clostridium beijerinckii YVU1 was able to produce comparable amount of ABE with previous reports. Therefore, we can state that the utilization of BCR as substrate for C. beijerinckii YVU1 leads to an economical bioprocess for the microbial production of ABE.

“…Moreover, they can be obtained from agricultural and industrial wastes or food processing by-products, allowing the valorization of discarded materials [14]. Consequently, several green composites have been recently developed using a wide variety of fillers derived from plants and trees such as pineapple leaf fibers [15], babassu nut shell flour [16], jute fabric [17], banana stem fiber [18], orange peel [19], coconut fibers [20], rice husk [21], almond shell [22] walnut shell [23], etc. It is evident that each type of plant has a specific chemical composition and structure.…”

Evaluation of Different Compatibilization Strategies to Improve the Performance of Injection-Molded Green Composite Pieces Made of Polylactide Reinforced with Short Flaxseed Fibers

Green composites made of polylactide (PLA) and short flaxseed fibers (FFs) at 20 wt % were successfully compounded by twin-screw extrusion (TSE) and subsequently shaped into pieces by injection molding. The linen waste derived FFs were subjected to an alkalization pretreatment to remove impurities, improve the fiber surface quality, and make the fibers more hydrophobic. The alkali-pretreated FFs successfully reinforced PLA, leading to green composite pieces with higher mechanical strength. However, the pieces also showed lower ductility and toughness and the lignocellulosic fibers easily detached during fracture due to the absence or low interfacial adhesion with the biopolyester matrix. Therefore, four different compatibilization strategies were carried out to enhance the fiber–matrix interfacial adhesion. These routes consisted on the silanization of the alkalized FFs with a glycidyl silane, namely (3-glycidyloxypropyl) trimethoxysilane (GPTMS), and the reactive extrusion (REX) with three compatibilizers, namely a multi-functional epoxy-based styrene-acrylic oligomer (ESAO), a random copolymer of poly(styrene-co-glycidyl methacrylate) (PS-co-GMA), and maleinized linseed oil (MLO). The results showed that all the here-tested compatibilizers improved mechanical strength, ductility, and toughness as well as the thermal stability and thermomechanical properties of the green composite pieces. The highest interfacial adhesion was observed in the green composite pieces containing the silanized fibers. Interestingly, PS-co-GMA and, more intensely, ESAO yielded the pieces with the highest mechanical performance due to the higher reactivity of these additives with both composite components and their chain-extension action, whereas MLO led to the most ductile pieces due to its secondary role as plasticizer for PLA.

“…Polymer biocomposites can be defined as materials formed by a biodegradable polymer matrix and a filler derived from natural biomass [3,4]. Among the various polymer biocomposites, polyvinyl alcohol (PVA) and starch based composites have been considered as one of the most promising biodegradable materials [5]. However, widespread applications of the blends of PVA and starch are limited because of their water sensitivity, poor thermal and mechanical properties.…”

The utilization of biochar in polymer composites can be considered as a sustainable approach that provide valorization of a waste to a value-added material and at the same time diminish biowaste in a smart way. This study is focused on the evaluation of biochar as a filler in polyvinyl alcohol /corn starch composites. The composites were prepared via solution mixing and casting method using citric acid as a plasticizer and glutaraldehyde as a cross-linker. Distribution of biochar in the PVA/starch matrix was evaluated by optical microscopy. The structural features of composites were characterized using FTIR spectroscopy. Effects of biochar loading ratio (0-12 wt%) on the thermal stability of the PVA/starch blends were determined by differential scanning calorimetry and thermogravimetric analyses. The decomposition temperatures of the PVA/starch/biochar composites decreased in comparison to PVA/starch composites.
