METHOD FOR MANUFACTURING MINERAL PAPER BY USING SHELLS

The present invention relates to a method for manufacturing mineral paper by using shells and, specifically, to a method for manufacturing paper mixed with polyethylene by subjecting shells discarded from shellfish such as oysters and clams to processes such as removal of impurities, firing, and mixing. The mineral paper of the present invention is manufactured by using shells (CaCO3) instead of using wood and water as raw materials for paper production and thus has effects of securing depleted resources and improving the natural environment. In addition, by using shells discarded in large quantities after harvesting oysters, clams, etc., the mineral paper has effects of addressing issues such as environmental pollution and damage to natural scenery caused by shells, reducing costs required for shell disposal, and creating high added value. La présente invention concerne un procédé de fabrication de papier minéral en utilisant des coquilles, et, de manière spécifique, un procédé de fabrication de papier mélangé à du polyéthylène en soumettant des coquilles rejetées à partir de crustacés, tels que des huîtres et des palourdes, à des processus, tels que l'élimination des impuretés, la cuisson et le mélange. Le papier minéral de la présente invention est fabriqué en utilisant des coquilles (CaCO3) au lieu d'utiliser du bois et de l'eau comme matières premières pour la production de papier, ce qui a pour effet de préserver les ressources épuisées et d'améliorer l'environnement naturel. En outre, en utilisant les coquilles rejetées en grandes quantités après la récolte des huîtres, des palourdes, etc., le papier minéral a pour effet de résoudre des problèmes, tels que la pollution de l'environnement et les dommages causés aux paysages naturels par les coquilles, de réduire les coûts nécessaires à l'élimination des coquilles et de créer une forte valeur ajoutée. 본 발명은 패각을 이용한 돌종이(mineral paper) 제조방법으로서, 구체적으로는 굴, 조개 등과 같은 패류에서 폐기되는 패각을 불순물 제거, 소성, 혼합 등의 공정을 진행하여 폴리에틸렌과 혼합한 종이를 제조하는 방법에 관한 것이다. 본 발명의 돌종이는 종이 제조의 원료로 나무와 물을 사용하는 대신 패각(CaCO3)을 사용하기 때문에 고갈되는 자원확보와 자연환경 개선의 효과가 있다. 또한 굴, 조개 등을 수확하고 난 뒤 대량으로 폐기되는 패각을 이용함으로써, 패각으로 인한 환경오염 및 자연경관 훼손 등의 문제를 해결하고, 패각 폐기에 쓰이는 비용 절감과 고부가가치를 창출하는 효과가 있다.
