La diseñadora y arquitecta londinense Mooka Srisurayotin ha desarrollado un material bioalternativo al hormigón tradicional utilizando conchas de ostra trituradas para sustituir a la piedra caliza, ingrediente clave del cemento.

London-based designer and architect Mooka Srisurayotin has developed a bio-alternative material to traditional concrete using crushed oyster shells to replace limestone, a key ingredient in cement. Oyster[Crete], as it is known, aims to be utilized in large-scale building materials eventually.

Srisurayotin began Oyster[Crete] as a research project while investigating alternative building materials. Inspired by the large quantities of oyster shells discarded by restaurants—up to 5,000 shells a day—she saw their potential due to their chemical similarity to limestone. 

The process of creating Oyster[Crete] involves collecting discarded oyster shells from restaurants in East London and combining them with sand and clay to form a natural composition. The mixture contains 80% oyster shells.

Traditional cement production is responsible for at least 6% of global CO2 emissions. By using oyster shells, Srisurayotin's Oyster[Crete] addresses carbon dioxide emissions from not only the coal used to heat kilns but also during the conversion of limestone into clinker. 

One of the initial products made from Oyster[Crete] is an oyster tray, designed to be used in restaurants to serve oysters, closing the loop in a circular process. Although currently focusing on small objects, Srisurayotin aims to expand the use of Oyster[Crete] to larger construction applications in the future.



Transformación de conchas de ostra en un hormigón bioalternativo

¿Podría la humilde ostra ayudar al sector de la construcción a reducir su huella de carbono? El arquitecto y diseñador londinense Muka Sisirjaotin podría tener la respuesta con un nuevo proyecto sostenible. sostenible que ha desarrollado, Oystercrete. Oystercrete es un material bioalternativo al hormigón tradicional que utiliza ostras desechadas. conchas. Nuestro objetivo es utilizar este material sostenible en aplicaciones de construcción a gran escala. Oystercrete comenzó como un proyecto de investigación de Sisirjaotin, que estaba investigando materiales de construcción. Se inspiró en las conchas de ostra, después de ver cuántas son desechadas por los restaurantes. Pasaban como 5.000 conchas al día. Así que tomamos los proyectiles y vimos el potencial en los proyectiles y tiene el la misma composición química que la piedra caliza. Sisirjaotin es también fundador del estudio de diseño interdisciplinar Matterforms. Es aquí donde transforma las conchas de las ostras tras recogerlas de restaurantes de Este de Londres. Y luego los combinaríamos en una mezcla de hormigón de ostras y toda la composición dentro de este material es todo natural y los ingredientes clave, 80% conchas de ostras. También usamos arena y arcilla, pero en cantidades muy pequeñas. Es una alternativa ecológica al cemento, responsable de al menos el 6% de la producción mundial de cemento. de CO2. Sisirjaotin genera enormes volúmenes de dióxido de carbono, no sólo del carbón utilizado para calentar hornos, sino también durante la conversión de piedra caliza en clinker, una parte clave de la producción proceso. Esta bandeja para ostras es uno de los productos que Sisirjaotin ha creado con ostras de hormigón. Hemos diseñado esta bandeja para que pueda volver a los restaurantes y puedan servir ostras en una bandeja. Así que es como un proceso totalmente circular. Así que estos son una especie de nuestro punto de partida. Dice que actualmente se está centrando en objetos pequeños, pero que con el tiempo quiere utilizar ostras de hormigón para aplicaciones a gran escala.
