Zusammenfassung:A composite material comprising a biodegradable plastic and a fibrous material, especially one having a porosity ranging from 10 to 98 %. When immersed in water where acquatic animals and plants are growing, this material functions to remove nitrate nitrogen contained in water, whereby the environment for raising acquatic animals is well maintained and the growth of acquatic plants is promoted. La présente invention concerne une matière composite comprenant un plastique biodégradable et une matière fibreuse, notamment une matière dont la porosité varie dans la plage située entre 10 % et 98 %. Lorsqu'elle est immergée dans une eau où des animaux et des plantes aquatiques se développent, cette matière élimine l'azote des nitrates contenus dans l'eau. De ce fait, l'environnement qui favorise la croissance des animaux aquatiques est maintenu de façon appropriée et les plantes aquatiques se développent.
