A molded article produced by defibrating waste plastics to fiber fluffs and defibrating waste paper into fiber fluffs, mixing and interlacing the fluffs, and conducting thermal pressure-molding of the mixture to form a desired shape. The molded article using the waste plastics and waste paper as the principal materials can be produced without finely classifying the wastes according to their kinds. The molded article, which is light for its volume and has sufficient strength, can be provided economically. Cette invention porte sur un article moulé produit au moyen du défibrage de vieux plastiques qui permet d'obtenir des peluches fibreuses et du défibrage de vieux papiers qui permet d'obtenir des peluches fibreuses, du mélange et de l'entrelacement des peluches, et du moulage par pression thermique du mélange pour obtenir la forme désirée. L'article moulé fabriqué avec les vieux plastiques et les vieux papiers en tant que matériaux principaux peut être produit sans qu'il soit nécessaire de trier finement les déchets en fonction de leur type. L'article moulé qui est léger par rapport à son volume et cependant suffisamment résistant, peut être fabriqué à peu de frais.
