Abstract

L'invention concerne une composition servant à fabriquer un article formé comprenant de l'amidon, une fibre végétale pulvérisée ou un engrais organique obtenu en traitant des déchets comme matière première. Cette composition est produite au moyen d'un procédé consistant à mélanger la matière première avec de la farine de blé et un liant et à malaxer le mélange ainsi obtenu de manière homogène. L'invention concerne également un article formé obtenu à partir de cette composition. Cette composition peut servir à fabriquer, sans utiliser de résine synthétique, un article formé qui présente une aptitude au formage similaire à celle d'un article formé à partir d'une résine synthétique. En outre, cette composition peut être décomposée par un microbe ou un rayon ultraviolet.
