The journal provides a scientific platform that focuses on the development of sustainable materials, offering visible solutions for designers and decision-makers to achieve better sustainable design possibilities and contribute to creating more sustainable societies and functional green products for the near future. As the synergy between the structural integrity and the behaviour of a sustainable material is vital for the design of green products, several characteristics of sustainable materials, including physical, chemical, mechanical, and electrical, must be considered from both ecological and economic perspectives. The journal thus encourages the submission of cutting-edge original research articles and reviews covering a broad spectrum of related engineering topics, including, but not limited to:
