The use of comminuted, recycled glass powders as a filler in molded plastic parts is disclosed. The recycled glass preferably has rounded edges, which is a distinct advantage over conventional ground glass which has extremely sharp edges. Suitable comminuted glass is free from contaminants such as grinding compounds. The comminuted recycled glass filler can be used with a variety of different thermoplastics commonly used in injection molding, rotational molding, and blow molding of plastic parts.

De préférence, le verre recyclé a des bords arrondis, ce qui est un avantage déterminant par rapport au verre broyé classique, dont les bords sont extrêmement tranchants. Le verre broyé approprié est dépourvu de contaminants comme les composés de broyage. Le matériau de remplissage broyé recyclé est utilisable avec une variété de procédés thermoplastiques différents communément utilisés en moulage par injection, rotomoulage et moulage par soufflage de pièces en plastique.
