Advantages on Waste Management in Hydrogen Industry
The turn to hydrogen as an energy source is a fundamentally important task facing the global energetics, aviation and automotive industries. This step would reduce the negative man-made impact on the environment on the one hand, and provide previously inaccessible power modes and increased resources for technical systems, predetermining the development of an absolutely new life cycle for important areas of technology, on the other. The most important aspect in this case is the development of next-generation technologies for hydrogen industry waste management that will definitely reduce the negative impact of technology on the environment.

Aerogel
Aerogels are one of the most interesting materials of the 21st century owing to their high porosity, low density, and large available surface area. Historically, aerogels have been used for highly efficient insulation and niche applications, such as interstellar particle capture. Recently, aerogels have made their way into the composite universe.

Affecting Erosion Factors
Erosion is a major issue since it results in several problems, such as failure/collapse, the degradation of surfaces, severe accidents, and vulnerabilities in many industrial systems and processes. Surface degradation by erosion is a slow but nevertheless continuous and unpreventable process in numerous industries, such as the oil and gas industry; erosion also affects aircraft, steam engines, and the rotor blades of power plant drive turbines, including wet-steam turbines, as well as other turbine plants that operate on wet steam.

Agro-Food Waste Valorization for Sustainable Bio-Based Packaging
The increase in the generation of agro-food processing waste, coupled with uncontrolled disposal and inefficient recovery methods, has raised concerns among society, industries, and the research community. This issue is compounded by the accumulation of conventional synthetic packaging. Owing to their significant environmental and economic impacts, the development of sustainable, biocompatible, and biodegradable materials has become an urgent target. In this context, research efforts have been directed toward developing new packaging materials based on renewable sources, such as agro-food waste, contributing to the circular economy concept.

All-Cellulose Composites
Wood- or plant-based cellulose fibres have shown their potential as a reinforcement in composites for a relatively long time alongside the commonly used glass-fibre and carbon-fibre reinforcements. Whereas regular biocomposites suffer from fibre-matrix adhesion-related challenges, all-cellulose composites (ACCs) can overcome this problem by both matrix and reinforcement having the same or a similar chemical structure, which results in good interfacial compatibility. ACCs can provide an environmentally friendly alternative to conventional petrochemical-based materials since they are a type of single-polymer composites (SPCs) from biomass-derived cellulose, and as such, they are easily recyclable, and they originate from renewable sources.

Alloying Elements and Mechanical Characteristics of Mg-Based Materials
Magnesium alloys are widely employed in various applications due to their high strength-to-weight ratio and superior mechanical properties as compared to unalloyed Magnesium. Alloying is considered an important way to enhance the strength of the metal matrix composite but it significantly influences the damping property of pure magnesium, while controlling the rate of corrosion for Mg-based material remains critical in the biological environment. Therefore, it is essential to reinforce the magnesium alloy with a suitable alloying element that improves the mechanical characteristics and resistance to corrosion of Mg-based material. Biocompatibility, biodegradability, lower stress shielding effect, bio-activeness, and non-toxicity are the important parameters for biomedical applications other than mechanical and corrosion properties. The development of various surface modifications is also considered a suitable approach to control the degradation rate of Mg-based materials, making lightweight Mg-based materials highly suitable for biomedical implants.

Application of Additional Conductive Layers
Polymer composites are at increasingly used as structural materials replacing metal alloys due to their high strength-to-weight ratio and corrosion resistance. The conductivity of epoxy resin, depending on its type, ranges from 10−17 to 10−12 S/cm, so it is classified as an insulator, i.e., a material with a conductivity below 10−12 S/cm, while carbon fiber is about 6 × 102 S/cm, which allows it to be classified as a semiconductor, i.e., a material whose conductivity is between 10−12 and 103 S/cm. The EP/CF composite, on the other hand, has a conductivity of about 10−4–10−2 S/cm, that is, it also classifies as a semiconductor. The methods to improve the conductivity have been categorized into three groups: modification of the matrix with conductive fillers, modification of the composite reinforcement, and addition of layers with increased electrical conductivity to the composite.
