“…These treatments result in the isolation of the lignocellulosic fibers from the original biomass. In this context, the increase in the severity of the treatment leads to a reduction in the yield of the process, as well as a modification in the chemical composition of the resulting fibers [ 26 , 27 , 28 ]. According to the 12 Principles of Green Chemical Engineering, enunciated by Anastas and Zimmerman [ 29 ], the activity of scientists and engineers must converge in the design of new materials, products, processes, and systems that are beneficial to health and the environment.…”

Stiffness of material is a key parameter that allows the use of material for structural or semi-structural purposes. Besides, lightweight materials are increasingly calling the attention of the industry. Environmental impact is also increasing in its importance. Bio-based materials produced from renewable sources can be good candidates for structural purposes combining lightweight and low environmental impact. Nonetheless, similar mechanical properties of commodities have to be reached with such materials. In this work, composite materials from corn stover fibers as a bio-polyethylene reinforcement were produced and tested. The effect of coupling agents to improve the fiber–matrix interface has been evaluated. It has been found that coupling agent content influenced the stiffness of the materials, increasing the Young’s modulus and the material processability. The best performance was achieved for a 6% of coupling agent, corresponding to 4.61 GPa for 50 w/w% of corn stover fibers. Micromechanics showed the impact of the semi-random orientation of the fibers and the lesser impact of its morphology. It was possible to determine a triangular packing of the composites as a hypothesis for future research.

The large amount of cellulose found in Ulva sp. and its low percentage of lignin-like compounds make it an interesting raw material for partially substituting wood pulp to produce pulp and paper. This work shows the suitability of mild chemical treatments for papermaking using residual biomass from this green seaweed, harvested on the beaches, in order to give it added value. A chemical characterization was used to determine ethanol-benzene, hot water, and 1% soda extractives, ash content, holocellulose, α-cellulose, and acid-insoluble material. Cellulose extraction was performed with low proportions of soda and hydrogen peroxide, and it was subjected to a refining step. A design of experiments was used to explain the influence of soda (6%, 8%, and 10%) and hydrogen peroxide (2%, 4%, and 6%) based on oven-dry weight, plus refining (1000 PFI revolutions, 3000 PFI revolutions, and 5000 PFI revolutions). The results showed that to attain good paper strength, it is advisable to operate at maximum alkali charge, minimum peroxide concentration, and refine to a high degree.

“…A total of four different pulps were used for paper production, as reflected in Table 3, together with their basic characterization. The reference pulp presented 41 °SR, a typical value for brown-line recycled pulps (Biricik and Atik 2012;Moral et al 2017). When this pulp was enzymatically refined, drainability was kept almost constant with no significant changes in fibers' morphology, since length was merely decreased from 844 to 768 µm.…”

The present work shows the suitability of using industrial fluting papers as raw material for the development of four different substrates, enzymatically refined and/or containing cellulose nanofibers (CNF) in bulk. These four substrates were deeply studied and treated with different coating formulations, containing cellulose nanofibers, polyvinyl alcohol, native starch and alkyl ketene dimer, with the purpose of evaluating the benefits of using fiber-based packaging paper with improved mechanical, physical and barrier properties. The results showed that tensile properties of paper can be significantly improved if CNF are coated in combination with PVA, at the same time that grease resistance was improved, air permeability and water vapor transmission rate were decreased. The obtained papers presented interesting barrier properties to vapor and air, at the same time that unconceivable limits of breaking length were achieved (6.44 km). In addition, when a second layer of alkyl ketene dimer was coated on both sides of paper, water contact angle was significantly improved, being higher than 115°, although the rest of the properties were slightly worsened. Overall, the present work shows the feasibility of using recycled fibers for the production of high value-added papers that could be used for packaging purposes due to their improved barrier and mechanical properties, promoting bio-based economy and circularity of the resources.
