“…strain at break) is very low ($0.7%) and it reflects the poor elongation capacity compared to thermoplastic composites (usually up to 100% [21]). These flexural tests are in good agreement with previous tensile tests made on regular Arboform Ò and it confirms the wood-like mechanical behaviour of this composites [12].…”

“…The Arboform Ò composites consist of isolated lignin, natural fibres and natural additives which are elaborated through conventional thermoplastic processes such as injection molding [12]. The obtained composites have wood-like mechanical behaviour and some properties lies in the range of those of polyamides.…”

“…Carbon fibers produced from lignin based materials require a lower amount of thermo-stabilization and possess high tensile strength [12]. Lignin has been used to produce various polymers like ARBOFORM, polyesters and polyurethanes and various polymer blends with PVC, polyolefins, and rubbers are being currently developed [13-15]. Lignin has also been used as slow release nitrogenous fertilizers for soil and catalyst for the Kraft pulping process [10,16].…”

BackgroundLignin is often overlooked in the valorization of lignocellulosic biomass, but lignin-based materials and chemicals represent potential value-added products for biorefineries that could significantly improve the economics of a biorefinery. Fluctuating crude oil prices and changing fuel specifications are some of the driving factors to develop new technologies that could be used to convert polymeric lignin into low molecular weight lignin and or monomeric aromatic feedstocks to assist in the displacement of the current products associated with the conversion of a whole barrel of oil. We present an approach to produce these chemicals based on the selective breakdown of lignin during ionic liquid pretreatment.ResultsThe lignin breakdown products generated are found to be dependent on the starting biomass, and significant levels were generated on dissolution at 160°C for 6 hrs. Guaiacol was produced on dissolution of biomass and technical lignins. Vanillin was produced on dissolution of kraft lignin and eucalytpus. Syringol and allyl guaiacol were the major products observed on dissolution of switchgrass and pine, respectively, whereas syringol and allyl syringol were obtained by dissolution of eucalyptus. Furthermore, it was observed that different lignin-derived products could be generated by tuning the process conditions.ConclusionsWe have developed an ionic liquid based process that depolymerizes lignin and converts the low molecular weight lignin fractions into a variety of renewable chemicals from biomass. The generated chemicals (phenols, guaiacols, syringols, eugenol, catechols), their oxidized products (vanillin, vanillic acid, syringaldehyde) and their easily derivatized hydrocarbons (benzene, toluene, xylene, styrene, biphenyls and cyclohexane) already have relatively high market value as commodity and specialty chemicals, green building materials, nylons, and resins.

“…is applied [21,22]. For example, the Arboform® (developed at the Fraunhofer Institute for Chemical Technology, Pfinztal, Germany) composites consist of isolated lignin, natural fibers, and natural additives that are elaborated through conventional thermoplastic processes such as injection molding [23]. The addition of maleic anhydride-modified polymers (e.g., maleic anhydride-grafted polymers) represents a prominent method for compatibilizing fillers and polymers.…”
