“…Roldi‐Oliveira extracted hemicellulose through an alkaline method (using 10% w / v KOH, at 25°C for 3 h) from Curaua fibres and achieved a high yield. The film made of this hemicellulose had better thermal stability and elongation at break than other biodegradable polymers (PolylActic Acid and Poly hydroxybutyrate) and even polymeric films [ 65 ]. In another case, the alkaline (NaOH)‐alcoholic method was used to extract hemicellulose from sugarcane bagasse which was also used to prepare biodegradable package film.…”

Uncontrolled waste generation and management difficulties are causing chaos in the ecosystem. Although it is vital to ease environmental pressures, right now there is no such practical strategy available for the treatment or utilisation of waste material. Because the Earth's resources are limited, a long‐term, sustainable, and sensible solution is necessary. Currently waste material has drawn a lot of attention as a renewable resource. Utilisation of residual biomass leftovers appears as a green and sustainable approach to lessen the waste burden on Earth while meeting the demand for bio‐based goods. Several biopolymers are available from renewable waste sources that have the potential to be used in a variety of industries for a wide range of applications. Natural and synthetic biopolymers have significant advantages over petroleum‐based polymers in terms of cost‐effectiveness, environmental friendliness, and user‐friendliness. Using waste as a raw material through industrial symbiosis should be taken into account as one of the strategies to achieve more economic and environmental value through inter‐firm collaboration on the path to a near‐zero waste society. This review extensively explores the different biopolymers which can be extracted from several waste material sources and that further have potential applications in food packaging industries to enhance the shelf life of perishables. This review‐based study also provides key insights into the different strategies and techniques that have been developed recently to extract biopolymers from different waste byproducts and their feasibility in practical applications for the food packaging business.

“…The hemicellulose extracted from curaua fiber has a low molecular weight of around 118,000 g/mol 32 (probably similar to hemicellulose from jute fiber due to the same extraction method) and has a typical degree of polymerization (DP) of 140 33 . The literature reports the high complexity film formation from low molecular weight polymers 34 .…”

The bottleneck of hemicellulose as a bio-based material is its processability and property drawbacks (softening and hydrophilicity). Thus, mixing other biopolymers can be an alternative. This article proposes blending hemicellulose (10−50 wt%) with polyhydroxybutyrate (PHB) and poly (lactic acid) (PLA), using acetic acid and chloroform as casting solvents to improve its processability and thermal properties. The materials were thermally (TGA -thermogravimetric analysis), chemically (FTIR -Fourier transformer infrared) and morphologically (SEM -scanning electron microscopy) characterized. Finally, a multicriteria decision analysis (MCDA) evaluated the materials' properties to identify the optimum combination (casting solvent, biopolymer and hemicelluloses proportion) for producing an optimal blend. The MCDA established that the blend of hemicellulose:PHB (10:90 wt/wt) produced with acetic acid was optimum considering melting temperature and the crystallinity criteria. Moreover, higher hemicellulose concentration in the blends decreased the MCDA success rate, indicating the worst properties. PLA blends showed a higher degradation temperature than PHB. The PHB blends produced with acetic acid demonstrated improved properties when compared to chloroform, revealing its potential as a solvent.

This study investigates the influence of hemicellulose (Hc) on the chemical composition, thermal stability, mechanical properties, and morphology of carboxymethyl cellulose (CMC). Hc was isolated from oil palm trunk and then added into CMC at 10–30 wt% to prepare Hc‐CMC films via solution casting method. The addition of Hc resulted in reduced visual transparency, rendering the blend films opaque. Fourier transform infrared spectroscopy verified the chemical interaction between Hc and CMC by revealing persistent and robust hydrogen bonding at specific spectral peaks (3483–3045 cm−1). The interaction between Hc and CMC was further indicated by the rougher interfacial structure as revealed in scanning electron microscopy (SEM). Thermal analysis via differential scanning calorimetry and thermogravimetry analysis indicated a decrement in thermal stability as Hc loadings increased in the CMC films. The highest tensile properties were observed in Hc‐CMC blend films at a 20 wt% Hc loading, showcasing notable enhancement about 23%. The 20 wt% Hc‐CMC blend films appeared as more suitable blending composition which having an enhanced physicochemical, thermal, and mechanical properties. This finding underscores its potential applicability in diverse industrial sectors, particularly in packaging applications.
