Special Issue Information

Dear Colleagues,

In recent years, there has been an increasing global focus on sustainability and the urgent need to transition towards environmentally friendly practices in various industries. Engineering, as a key sector driving innovation and development, plays a crucial role in shaping a sustainable future. This Special Issue aims to explore the latest advancements and challenges in the field of sustainable materials for engineering applications.

Sustainable materials encompass a wide range of materials and technologies that minimize environmental impact while maintaining or even improving performance. This Special Issue welcomes original research, review articles, case studies, and perspectives that shed light on sustainable materials' applications across different engineering disciplines. The objective is to provide a comprehensive platform for researchers, scientists, engineers, and practitioners to share their insights, exchange knowledge, and present cutting-edge solutions to address sustainability challenges.

Potential topics of interest for this Special Issue include, but are not limited to:

Novel sustainable materials: Exploration and development of new materials with reduced environmental footprint, including bio-based materials, recycled materials, and materials with improved end-of-life management.

Life cycle assessment and environmental impact: Studies focusing on the assessment of sustainable materials' life cycle, including methodologies, tools, and case studies evaluating environmental impacts and resource consumption.

Sustainable material processing and manufacturing: Innovative techniques and technologies for sustainable material processing, including energy-efficient manufacturing processes, waste reduction, and pollution prevention.

Structural materials for sustainability: Advancements in sustainable materials for structural applications, such as high-performance concrete, sustainable metals, composites, and polymers.

Renewable energy materials: Materials for renewable energy technologies, including solar panels, wind turbines, energy storage systems, and fuel cells.

Sustainable materials for transportation: Materials and technologies for sustainable transportation, such as lightweight materials, electric vehicle components, and alternative fuel systems.

Sustainable materials for water and wastewater treatment: Development of sustainable materials for efficient and eco-friendly water treatment and wastewater management systems.

Case studies and real-world applications: Successful implementation of sustainable materials in engineering projects, showcasing their benefits, challenges, and lessons learned.

By bringing together diverse perspectives, this Special Issue seeks to foster interdisciplinary collaborations and promote the adoption of sustainable materials in engineering applications. It will serve as a valuable resource for researchers, engineers, policymakers, and stakeholders committed to driving sustainable development and creating a more environmentally conscious future.

Composting is a process that emits environmentally harmful gases: CO2, CO, H2S, and NH3, negatively affecting the quality of mature compost. The addition of biochar to the compost can significantly reduce emissions. For effective CO2 removal, high doses of biochar (up to 20%) are often recommended. Nevertheless, as the production efficiency of biochar is low—up to 90% mass loss—there is a need for research into the effectiveness of lower doses. In this study, laboratory experiments were conducted to observe the gaseous emissions during the first 10 days of composting with biochars obtained from mature composts. Biochars were produced at 550, 600, and 650 °C, and tested with different doses of 0, 3, 6, 9, 12, and 15% per dry matter (d.m.) in composting mixtures, at three incubation temperatures (50, 60, and 70 °C). CO2, CO, H2S, and NH3 emissions were measured daily. The results showed that the biochars effectively mitigate CO2 emissions during the intensive phase of composting. Even 3–6% d.m. of compost biochars can reduce up to 50% of the total measured gas emissions (the best treatment was B650 at 60 °C) and significantly increase the content of macronutrients. This study confirmed that even low doses of compost biochars have the potential for enhancing the composting process and improving the quality of the material quality. Full article

Yellow phosphorus slag (YPS) is a byproduct from the production of yellow phosphorus. It has potential pozzolanic activity and can be used as a supplementary cementitious material. However, the early strength of cement mortar decreases significantly with increasing YPS dosage, which restricts the utilization of YPS in cement and concrete. This study aimed to increase the pozzolanic activity of YPS ash by thermal activation. The strength method, alkali dissolution method and polymerization degree method were used to evaluate the effect of thermal activation at different temperatures on the pozzolanic activity of YPS ash. The results showed that YPS ash calcined at 800 °C helps to enhance the early strength because the fluorine in cuspidine (Ca4Si2O7F2) is insoluble, reducing the retarding effect on the mortar. The higher late strength of YPS ash calcined at 100 °C was due to the low polymerization degree of [SiO4]. The pozzolanic activity of YPS ash is positively correlated with the dissolution concentration of (Si + Al) and the compressive strength and negatively associated with the polymerization degree. This paper shows a possibility for the large-scale utilization of YPS. Full article
