“…L is able to give a large amount of char when heated at high temperature in an inert atmosphere, this feature is a basic aspect of flame retardant additives, since char reduces the combustion rate of polymeric materials [2]. Some papers described the efficiency of both pure L and L mixed with salts as flame retardant additives for polypropylene [3][4][5]. The antioxidant properties of L were used to stabilize polymer matrix composites against photoand thermo-oxidation [6][7][8].…”

There is a need for renewable resources as a raw material for commodity polymers. Lignin is one of the most important natural biopolymers from renewable resources due to its suffi cient supply, robust material properties and the fact that its use does not compete with the food supply. Lignin has been investigated since the late 19th century, but its applications are limited due to poor processability, low reactivity and intrinsic heterogeneity depending on the plant source and isolation methods used. Current strategies for using lignin in modern materials center on integrating it with other natural or synthetic polymers. This review article introduces the technological importance of lignin and focuses on copolymers and blends based on lignin in a broad range of applications.

“…Lignin or its byproducts could be used as a surfactant (Zhou et al 2015), and in combination with other materials, it could act as an antimicrobial, antifungal, and antioxidant agent (Dong et al 2011). It also absorbs UV radiation and exhibits flame-retardant properties (De Chirico et al 2003). Furthermore, lignin can be used in epoxy resins (Lora and Glasser 2002), green composites (Bertini et al 2012;Thakur et al 2014), and as filler in tires (Frigerio et al 2014;Barana et al 2016a).…”

The lignocellulosic materials produced after each step of a biorefinery plant using simultaneous saccharification and fermentation (SSF) technology on wheat straw (Triticum spp.) for bioethanol production were characterized by spectroscopic and chromatographic techniques in order to investigate the macromolecular interactions between the lignin and polysaccharides. In order to valorize the lignin cakes, a purification step was set up and the extraction conditions (acid pretreatment, temperature, time, and NaOH concentration) were optimized by a chemiometric approach in terms of yield and purity. Residual carbohydrate impurities, free and/or chemically bonded to lignin (lignin carbohydrates complexes), were individuate as the most critical factor for a satisfactory lignin extraction. Finally, the lignin samples collected according to the optimized extraction conditions were chemically characterized and low molecular weight, high phenols concentration, and low carboxylic acids content were recognized as interesting features for industrial applications.
