Special Issue Information

Dear Colleagues,

The emergence of concepts and production models such as the bioeconomy and circular economy mark the path along which society must redirect its course to achieve real sustainable development.

Implementation and continuous development of the bio- and circular economy in most sectors of industry and society can ensure an improved quality of life, both now and for future generations. In maintaining this paradigm, the scientific community plays a very important role in generating the basic knowledge that gives rise to technology and allows developments in the laboratory to be transferred to society.

The integral valorization of lignocellulosic biomass is a fundamental pillar of sustainable development. The transformation of lignocellulosic biomass for the production of materials, energy, platform molecules and chemicals through sustainable, scalable, and economically viable processes is a current challenge for the scientific community and other relevant stakeholders.

After the success of the previous Special Issue on “Lignocellulosic Biomass”, we are pleased to invite researchers to contribute to the second Special Issue. Similarly, the aim of this second Special Issue is to compile the latest advances in the characterization, transformation and application of lignocellulosic biomass and its by-products. The continuous progress and the high degree of innovation of recent times in this area make it necessary to periodically review these advances in order to serve as a reference for researchers interested in this area.

Green composites, composed of bio-based matrices and natural fibers, are a sustainable alternative for composites based on conventional thermoplastics and glass fibers. In this work, micronized bleached Eucalyptus kraft pulp (BEKP) fibers were used as reinforcement in biopolymeric matrices, namely poly(lactic acid) (PLA) and poly(hydroxybutyrate) (PHB). The influence of the load and aspect ratio of the mechanically treated microfibers on the morphology, water uptake, melt flowability, and mechanical and thermal properties of the green composites were investigated. Increasing fiber loads raised the tensile and flexural moduli as well as the tensile strength of the composites, while decreasing their elongation at the break and melt flow rate. The reduced aspect ratio of the micronized fibers (in the range from 11.0 to 28.9) improved their embedment in the matrices, particularly for PHB, leading to superior mechanical performance and lower water uptake when compared with the composites with non-micronized pulp fibers. The overall results show that micronization is a simple and sustainable alternative for conventional chemical treatments in the manufacturing of entirely bio-based composites. Full article

The salinity of European soil is increasing every year, causing severe economic damage (estimated 1–3 million hectares in the enlarged EU). This study uses the biomass of halophytes—tall fescue (grass) and hemp of the Białobrzeskie variety from saline soils—for bioenergy, second generation biofuels and designing new materials—fillers for polymer composites. In the bioethanol obtaining process, in the first stage, the grass and hemp biomass were pretreated with 1.5% NaOH. Before and after the treatment, the chemical composition was determined and the FTIR spectra and SEM pictures were taken. Then, the process of simultaneous saccharification and fermentation (SSF) was carried out. The concentration of ethanol for both the grass and hemp biomass was approx. 7 g·L−1 (14 g·100 g−1 of raw material). In addition, trials of obtaining green composites with halophyte biomass using polymers (PP) and biopolymers (PLA) as a matrix were performed. The mechanical properties of the composites (tensile and flexural tests) were determined. It was found that the addition of a compatibilizer improved the adhesion at the interface of PP composites with a hemp filler. In conclusion, the grass and hemp biomass were found to be an interesting and promising source to be used for bioethanol and biocomposites production. The use of annually renewable plant biomass from saline soils for biorefinering processes opens up opportunities for the development of a new value chains and new approaches to sustainable agriculture.
