Special Issue Information

Dear Colleagues,

The global economy is shifting towards a bioeconomy, and there is continuous pressure to substitute petroleum-based materials with biosourced, sustainable, and renewable ones, including biocomposites. Biocomposites are increasingly interesting as a renewable, environmentally friendly alternative to non-renewable materials. They contribute to reaching environmental targets by reducing greenhouse gas emissions (GHG) and carbon footprint. They also attenuate the impact of climate change. Thus, they contribute to building a foundation of sustainability and bioeconomy worldwide. The Euromag2025 Conference entitled “Biobased Materials for Circular Economy” addresses these issues. Manuscripts presented at this conference aim to address the challenges and opportunities of biomass valorization for the production of fossil-free biocomposites from the extraction of natural biopolymers at macro and nanoscale levels to the reuse and recycling in circular systems.

This Special Issue includes a collection of selected manuscripts presented at the Euromagh2025 Conference but is not limited to. The potential topics of interest include but are not limited to the following:

  • Processing of biocomposites and nano-biocomposites;
  • Mixtures rheology and processing;
  • Advanced characterization of biocomposites;
  • Matrix-fiber adhesion and interactions;
  • Properties, structure, and rupture mechanisms;
  • Properties modeling and optimization;
  • End-use and application;
  • Recycling, reuse, and circularity;
  • Sustainability, environmental impacts, and life cycle analysis;
  • Contribution of biocomposites to circular economy, climate change attenuation, and GHG emission mitigation.

The development of biocomposites derived from wheat flour and Hermetia illucens (black soldier fly) larvae flour presents a viable and sustainable alternative to conventional petroleum-based plastics, which contribute significantly to environmental degradation. The incorporation of cellulose nanocrystals (CNCs) is anticipated to enhance the functional properties of these materials, particularly for food packaging applications. The objective of this study was to develop and characterise biodegradable composites formulated from wheat and larvae flours, and to evaluate the effect of CNC addition on their physicochemical, mechanical, and structural properties. The biocomposites were produced using compression moulding and subsequently subjected to comprehensive characterisation. The results indicated that the addition of CNCs markedly improved the optical, barrier, and mechanical properties of the composites. These improvements render the materials suitable for packaging systems requiring moisture retention and reduced permeability to water vapour. From a mechanical perspective, composites incorporating CNCs exhibited increased tensile strength and stiffness, although a reduction in elongation at break was observed when compared to those prepared solely with larvae flour (LF). Scanning electron microscopy (SEM) analyses revealed that higher concentrations of larvae flour yielded composites with fewer surface fractures and reduced porosity. In conclusion, the utilisation of wheat and insect larvae flours, in combination with cellulose nanocrystals, represents an innovative and environmentally responsible approach for the development of biodegradable composites suitable for eco-friendly food packaging applications.

The process of formation of composite systems based on nanosilica A-300 and biologically active substances (BAS), namely gallic acid (GA), glycyrrhizic acid (GLA), and its salts, was studied using a set of physicochemical methods. It was shown that when BAS are immobilized on the silica surface by the method of joint grinding in a porcelain mortar, they pass into a nanosized X-ray amorphous state. Water adsorbed on the surface of such composite systems is also in a clustered state, and the radius of adsorbed water clusters is in the range of 0.4–50 nm. The chloroform environment has a complex effect on the size of water clusters. In general, there is a tendency for the radius of water clusters to increase when air is replaced by a chloroform environment. However, this does not always lead to a decrease in the interfacial energy. The possibility of the existence of metastable ice in the temperature range up to 287 K, stabilized by the surface of composite systems, was discovered. The amount of such ice can reach 20% of the total water content in the sample. The possibility of using complex viscosity measurements for hydrated silica powders and silica containing immobilized biologically active substances was shown. These measurements allow recording changes in the phase state of complex mixtures during the formation of compact composite forms under the influence of periodic mechanical loading. Full article

This study analyses the effect of lignin extracted from the Dominico-Harton banana on the physicochemical properties of biodegradable methylhydroxyethylcellulose (MHEC) composites. Lignin was obtained by grinding and sieving, followed by treatment with sulphuric acid and subsequent separation via centrifugation. Films were developed using the casting method, incorporating lignin and glycerol in a matrix of MHEC dissolved in distilled water. They were characterised according to their physical, barrier, mechanical, optical, and antioxidant properties, using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS). The results showed that lignin provides antioxidant capacity and improves mechanical and barrier properties, while MHEC contributes flexibility and biodegradability. These films have a dense and resistant structure, with potential applications in food packaging, agriculture, and medicine. The research highlights the use of agricultural waste to develop sustainable materials as an alternative to conventional plastics. Full article
