Special Issue Information

Dear Colleagues,

There is currently an intensive discussion ongoing regarding the relationship between sustainable development and circular economy. Even if the relationships between these concepts are not explicitly expressed, it is clear that their common goal is a sustainable society. The basis of this understanding is that natural resources provide input for the production and consumption of materials and products, and at the same time, after the end of their useful life, they serve as a stock of materials in the form of waste. This results in clear dependence on a circular economy, sustainable development, and the quality of the environment.

Important areas related to this are advanced material research as well as technological development, the basis of which is the development and production of sustainable products and processes. The development, modification, and recycling of materials are an integral part of circular economy and sustainability strategies. The importance is also evident in the increasing adoption of these terms in the scientific academic, industrial, and economic fields.

The aim of this Special Issue is to publish original research articles in areas related to the development and modification of new as well as recycled materials and their application possibilities. At the same time, studies focused on innovative technological methods for the processing and recovery of industrially important metals and their alloys, non-metallic materials, and composites are also welcome. Additionally, innovative procedures for testing, increasing efficiency, and optimizing processes aim to recover materials to improve the sustainability of Earth’s resources. Research related to any area of the materials science will contribute to the improvement of the mechanical, chemical, electrical, magnetic, acoustic, and thermal properties of the materials, as well as the understanding of the inter-relationship between the composition, structure, and properties of a material. Contributions that use multicriteria analysis or LCA assessment methods for comparing products and processes with a focus on environmental, technological, and economic aspects and impacts will also be greatly appreciated.

The scope encompasses scientific and engineering fields such as materials, metallurgy, chemical, mechanical, electrotechnical, environmental, biomedical, aerospace, industrial, and Earth resources. The fields of operation are not limited, and may include physical metallurgy, progressive materials, nanomaterials, progressive technologies, structure, chemical composition and properties of materials, hydrometallurgy, pyrometallurgy, biohydrometallurgy, electrometallurgy, primary and secondary materials, recycling technologies, modeling and simulation, SEM, XRF, XRD, LCA assessment, eco-design, mechanics of materials, ceramics, metals and metal alloys, non-metals, composites, electromobility, batteries and accumulators, electronics, hydrogen technologies, and applications of materials in various areas.

With the large-scale application of lithium-ion batteries (LIBs) in various fields, spent LIBs are considered one of the most important secondary resources. Few studies have focused on recycling anode materials despite their high value. Herein, a new efficient recycling and regeneration method of spent anode materials through the combination of thermal and wet metallurgical approaches and restored graphite performance is presented. Using this method, the lithium recycling ratio from spent anode materials reaches 87%, with no metal impurities detected in the leaching solution. The initial Coulombic efficiency of the recycled graphite (RG) materials is 90.5%, with a reversible capacity of 350.2 mAh/g. Moreover, RG shows better rate performance than commercial graphite. The proposed method is simple and efficient and does not involve toxic substances. Thus, it has high economic value and application potential in graphite recycling from spent LIBs. Full article

Rotational moulding is a unique low-shear process used to manufacture hollow parts. The process is an excellent process method for batch processing, minimal waste and stress-free parts. However, the process has drawbacks such as long cycle times, gas dependency and a limited palette of materials relative to other process methods. This review aimed to shed light on the current state-of-the-art research contributing towards sustainability in rotational moulding. The scope of this review broadly assessed all areas of the process such as material development, process adaptations and development, modelling, simulation and contributions towards applications carving a more sustainable society. The PRISMA literature review method was adopted, finding that the majority of publications focus on material development, specifically on the use of waste, fillers, fibres and composites as a way to improve sustainability. Significant focus on biocomposites and natural fibres highlighted the strong research interest, while recyclate studies appeared to be less explored to date. Other research paths are process modification, modelling and simulation, motivated to increase energy efficiency, reduction in scrap and attempts to reduce cycle time with models. An emerging research interest in rotational moulding is the contribution towards the hydrogen economy, particularly type IV hydrogen vessels. Full article
