Ecomaterials (ECO) is an open access journal, which provides a forum for studies in the field of eco-materials. The submitted manuscript will go through a rigorous double blind peer-reviewed process. Ecomaterials refer to materials (or material technologies) that possess excellent characteristics with good performance, which can be manufactured, used, and recycled or disposed of, while having only a low impact on the environment as well as being kind to humans. Ecomaterials provides a more comprehensive and systematic introduction to different types of environmentally-friendly materials.
