AbstractThe natural fiber (NF) reinforced composites, so called eco‐composites, are subject of many scientific and research projects, as well as many commercial programs. The growing global environmental and social concern, high rate of depletion of petroleum resources, and new environmental regulations have forced the search for new composites and green materials, compatible with the environment. The aim of this article is to present a brief review of the most suitable and commonly used biodegradable polymer matrices and NF reinforcements in eco‐composites, as well as some of the already produced and commercialized NF eco‐composites.
