ThSustainability is an approach aimed at preserving the capacity of future generations to meet their needs by using natural resources efficiently. This concept seeks to ensure the coexistence of environmental, economic, and social elements in harmony. In the United Nations’ Brundtland Report, sustainable development is defined as “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (World Commission on Environment and Development, 1987).

In Türkiye, waste management policies are shaped in line with environmental sustainability principles, based on both national legislation and legal frameworks harmonized with the European Union. Chief among these is the Environmental Law (Law No. 2872), which sets the foundation for a waste management hierarchy that includes prevention, reduction, reuse, recycling, energy recovery, and final disposal. Waste management systems are implemented through detailed practices, including the separate han

Energy efficiency in production refers to the reduction of energy consumption per unit of service or product, without decreasing the quality or quantity of output in industrial and manufacturing operations. This concept aims to produce more output with the same amount of energy or achieve the same output using less energy. Energy efficiency not only saves energy but also provides multifaceted benefits including efficient resource use, cost reduction, and environmental sustainability. Advancing t

SoSolar energy is the process by which electromagnetic radiation generated by thermonuclear fusion reactions in the Sun reaches Earth and is converted into heat and electrical energy. The Sun produces approximately 3.86×10²⁶ watts of power per second, of which about 1.74×10¹⁷ watts reaches Earth’s atmosphere. This amount corresponds to roughly 15,000 times the world’s annual energy demand.Solar radiation spans a broad electromagnetic spectrum including visible, ultraviolet (UV), and infrared (IR)

For railway lines to function safely, efficiently, and with long service life, the substructure must be properly maintained. In this context, the ballast layer plays a critical role. However, over time, ballast becomes contaminated, compacted, or loses its desired physical properties, negatively affecting both track geometry and ride comfort. To address this issue, ballast cleaning machines were developed to clean and recycle existing ballast, thereby reducing maintenance costs and contributing
