Title (EN) A METHOD OF PROCESSING SHELL WASTE
(FR) PROCÉDÉ DE TRAITEMENT DE DÉCHETS DE COQUILLE
Abstract:
(EN) There is provided a method of processing shell waste for recovering components comprised in shell of shellfish, the method comprising: mixing the shell waste with a denaturing agent or water at a pre-determined temperature for a pre-determined period of time to form a first mixture; filtering the first mixture to obtain a filtrate and a residue, wherein a first component is recovered from the filtrate; contacting the residue obtained from the filtering with carbon dioxide to form a suspension comprising a second component; and collecting a third component as balance residue following the contacting, wherein the first component is one or more proteins, the second component is a calcium salt, and the third component is chitin.
(FR) L'invention concerne un procédé de traitement de déchets de coquille pour récupérer des composants contenus dans une coquille de mollusques et crustacés. Le procédé comprend: le mélange des déchets de coquille avec un agent de dénaturation ou avec de l'eau à une température prédéterminée pendant une période de temps prédéterminée pour former un premier mélange; le filtrage du premier mélange pour obtenir un filtrat et un résidu, un premier composant étant récupéré à partir du filtrat; la mise en contact du résidu obtenu lors du filtrage avec du dioxyde de carbone pour former une suspension comprenant un second composant; et la collecte d'un troisième composant en tant que résidu d'équilibre après la mise en contact, le premier composant étant une ou plusieurs protéines, le second composant étant un sel de calcium, et le troisième composant étant la chitine.
