Jóvenes fabrican aspiradora gigante para eliminar micro plásticos de las playas.

La contaminación por microplásticos que azota a las playas y a los océanos, inspiró la acción a 12 estudiantes de ingeniería de la Universidad de Sherbrooke, en  Quebec, Canadá.

Tuvieron una gran idea: desarrollar una nueva aspiradora que puede recolectar microplásticos sin quitar nada de arena de la playa.

Y lo lograron. Es un gran avance, teniendo en cuenta que es sumamente difícil recoger los millones de pequeños microplásticos que hay en las playas y separarlos de la arena.

La máquina bautizada Hoola ONE nació de un proyecto que debían completar los estudiantes como parte de su licenciatura en ingeniería mecánica.

Inspirados por la sugerencia de un amigo, se pusieron en contacto con una organización hawaiana que trabaja para limpiar las playas del archipiélago.

Los jóvenes comprobaron la efectividad de Hoola ONE en una de las costas más contaminadas de Hawái, eliminando todos los residuos, sin quitar la arena de las costas.

¿Cómo funciona?

La manguera aspira el plástico y la arena, invirtiendo todo en un gran tanque de agua.

Como las rocas son más pesados que los residuos, estas se hunden en el fondo del recipiente para ser arrojadas a la playa nuevamente.

Hawaii Wildlife Fund les comunicó que su mayor desafío era limpiar micropartículas de plástico, de menos de cinco milímetros de tamaño.

Por lo tanto, la máquina de los jóvenes inventores está equipada con filtros capaces de recuperar micropartículas de hasta 50 micras (una micra es la mitad del grosor de un cabello humano).

Su primer desafío fue la playa de Kamilo Hawaiian considerada como una de las más contaminadas del mundo.

La separación de la arena y plástico comienza su proceso por decantación. La arena procesada cae al fondo, el plástico sube a la superficie y flota.

De esta forma, al crear un desbordamiento en el tanque, se pueden recuperar todas las partículas de plástico redirigidas hacia filtros que van hasta a 50 micrones.

Luego, la arena limpia se devuelve a la playa. La máquina puede procesar 15 metros cuadrados por hora y debe limpiarse periódicamente, debido al contacto con el agua salada.

Los jóvenes ganaron la edición 2019 del Fowler Global Social Innovation Challenge y el primer premio en la categoría “Changemaker”. Vencieron a 44 equipos que representaban a más de 25 universidades y 12 países.
