Cleaner Materials (ISSN: 2772-3976) is an international, cross-disciplinary companion journal to Journal of Cleaner Production that publishes original full-length research articles, short communications and reviews in applied or fundamental science of physical, chemical, mechanical, and user experience aspects of cleaner and sustainable materials with special attention to contributions that reduce the knowledge gap between materials and system designs. It provides a scientific platform for physicists, chemists, material scientists, engineers, product designers and other technical experts to contribute innovative works and combine the different disciplines in Cleaner Materials. Disciplines include but not limited to: waste recycling and upcycling methodologies materials with low energy consumption for application low-emission materials low-noise materials new materials incorporating living organisms such as algae and bacteria, living materials bio-based materials carbon based catalyst self-healing materials shape memory composites biochar and hydrochar silica and zeolite-based materials material pelletization technologies pyrolysis and hydrothermal carbonization photovoltaic materials hydrogen fuel We encourage those interested in organizing a special issue or a virtual special issue within the scope of the journal to fill out this form and contact the editors-in-chief for more information.
