Maritime recycling area
A site, where one or several used materials have been recycled to make something new in a maritime setting. 
A site, where used objects, such as a ship hull, have been recycled to build something new into underwater landscape. 
For example, old ship's hulls recycled as foundation for a breakwater, pier or jetty.
Recycling is separated from reuse, where for example, an old ship hull is reused, when its primary new function remains as a floating vessel.
