“…Kaur has also recently analyzed the role of biorefineries in obtaining polymers (both thermoset and thermoplastic) from biomass residues, stating that these are of key importance for the development of small industries devoted to the obtaining of polymers (such as poly(furfuryl)) alcohol and PFA, which is a biobased polymer with flame retardant characteristics [ 27 ], but also biochar, sweeteners for the food industry, adhesives or cellulose nanofibrils with application in composites with antioxidant, antimicrobial or superabsorbent properties [ 28 ]. Peng [ 29 ] proposes the use of hemicellulose as a natural renewable raw material for the production of ethylene-vinyl alcohol, polyvinylidene chloride or hydrogel networks, which are fully biodegradable; however, hemicellulose needs to be chemically modified to reduce hydroxyl and carboxyl free groups and increase the polymer chain stability. “Lignin-first” biorefinery has been proposed by Carpita and McCann [ 30 ] in order to increase the value of lignin-derived compounds, removing first aromatic compounds, and then processing cellulose and other carbohydrates.…”

Are Natural-Based Composites Sustainable?

This paper assesses the aspects related to sustainability of polymer composites, focusing on the two main components of a composite, the matrix and the reinforcement/filler. Most studies analyzed deals with the assessment of the composite performance, but not much attention has been paid to the life cycle assessment (LCA), biodegradation or recyclability of these materials, even in those papers containing the terms “sustainable” (or its derivate words), “green” or “eco”. Many papers claim about the sustainable or renewable character of natural fiber composites, although, again, analysis about recyclability, biodegradation or carbon footprint determination of these materials have not been studied in detail. More studies focusing on the assessment of these composites are needed in order to clarify their potential environmental benefits when compared to other types of composites, which include compounds not obtained from biological resources. LCA methodology has only been applied to some case studies, finding enhanced environmental behavior for natural fiber composites when compared to synthetic ones, also showing the potential benefits of using recycled carbon or glass fibers. Biodegradable composites are considered of lesser interest to recyclable ones, as they allow for a higher profitability of the resources. Finally, it is interesting to highlight the enormous potential of waste as raw material for composite production, both for the matrix and the filler/reinforcement; these have two main benefits: no resources are used for their growth (in the case of biological materials), and fewer residues need to be disposed.

“…Based on their excellent biodegradability, biocompatibility, and bioactivity, HCs and their derivatives have currently received considerable attention in terms of material applications such as edible coatings and films or coatings for paper and board for the packaging industry, hydrogels and binders for medicine or drug delivery and release in the pharmaceutical field, functional composites for heavy metals, and dye adsorption in wastewaters treatment and textile industry, as well as for obtaining biofuels [12][13][14][15][16][17].…”

Xylan Hemicellulose: A Renewable Material with Potential Properties for Food Packaging Applications

2021

Xylan hemicelluloses are considered the second most abundant class of polysaccharides after cellulose which has good natural barrier properties necessary for foods packaging papers and films. Xylan exists today as a natural polymer, but its utilisation in packaging applications is limited and not sufficiently analysed. In this study, the performances of hardwood xylan hemicellulose in forming uniform films and as biopolymer for paper coatings were analysed. The xylan-coated paper and film samples were tested regarding their water, air, and water vapour permeability, water solubility, mechanical strength, and antimicrobial activity against pathogenic bacteria. Structural analyses of xylan hemicelluloses emphasised a high number of hydroxyl groups with high water affinity. This affects the functional properties of xylan-coated papers but can facilitate the chemical modification of xylan in order to improve their hydrophobic properties and extend their areas of application. The obtained results unveil a promising starting point for using this material in food packaging applications as a competitive and sustainable alternative to petroleum-based polymers.

“…Hemicellulose is one of the natural polysaccharides abundant in plants and an important raw material for green and sustainable chemistry because of its non-toxic, biodegradable, renewable, and widely available source (Peng et al 2019). Biomass materials are potential materials to replace synthetic polymer materials, and the production of environmentally friendly materials from renewable biomass resources is an effective way to solve environmental pollution and depletion of petrochemical resources (Liao et al 2020).…”

Aquaternized hemicellulose (QH)/chitosan/reduced graphene oxide (rGO) composite film with good mechanical propertyand electrical conductivity was prepared bysolution-casting method. The effects of reduced graphene oxide contents on the structures and properties of the composite films were investigated.The mechanical property and electrical conductivity of the film with rGO containing 0.5 wt.% was reached 102.09 MPa and 12.8 × 10− 2 S/cm, respectively.Under the functions of hydrogen bonds and Van Der Waals forces, three components were combined to obtain QH/CS/rGO composite films with higher thermal stability and conductivity. Due to the compositing of rGO, the composite films showed good UV-blocking properties.This work provided a low-cost and sustainable pathway for the application of high-strength hemicellulose composite films with electrical conductivity and UV resistance in flexible electrode materials.
