The project aims at developing an innovative class of marine composites with a significantly reduced environmental impact. These new eco-materials will be created and used for boatbuilding, especially in the production of hulls or other structural parts of little boats (<10mt). Many research groups have been working for years with the scope to replace traditional materials, fiberglass as first. However, the present work has an important uniqueness: the new material will emerge from an unconventional use of sea waste.
