OCEAN CLEANING DEVICE SUCCESSFULLY COLLECTS PLASTIC FOR THE FIRST TIME For the first time since its initial design, a massive rubbish collecting device has successfully removed large amounts of plastic from an island of litter the size of France floating in the Pacific Ocean. The 25-year-old Dutch engineer and creator of the floating contraption, Boyan Slat, announced the achievement in early October on Twitter, together with a picture of some of the collected debris, wri- ting, “Our ocean cleanup system is now finally cat- ching plastic, from one-ton ghost nets to tiny micro- plastics! Also, anyone missing a wheel?” The enormous U-shaped contraption is made up of a 600m long floating boom with a skirt shaped net suspended below it. No power is needed to operate the device as the movements and currents of the sea are used to propel it through the rubbish. Announced by Mr. Stat in 2012, the development of the Ocean Clean up device has encountered some technical challenges along the way. When tested last year, the device was first unable to catch any de- bris due to the speed at which it was moving through the plastic, and later in the year, it broke apart due to rough sea conditions. But now, with the recent success of this device, the Ocean Clean Up Project can begin moving into its next phase. With plans to develop the technology further, increase the size of the structures, and de- ploy more of these devices so that they can gather the thousands of tonnes of plastic currently floating in the Pacific. The massive island of floating rubbish occupying 14 the waters between California and Hawaii is known as the “Great Pacific garbage patch”. It is the largest of five major offshore waste accumula- tion areas resulting from converging ocean currents and is estimated to contain 80,000 tonnes of plastic waste. In total, 99% of the rubbish found in the patch is plastic, with scientists noting that microplastics also appear to be accumulating rapidly within the area as well. All of this marine debris can have a massive im- pact on ocean wildlife, with animals such as sea turtles and albatrosses mistaking plastic bags or re- sin pellets for food, and other marine mammals such as seals becoming entangled in discarded plastic fishing nets. Microplastics and other litter can also decrease algae and plankton growth, which in turn can affect animals that rely on these organisms as a food sour- ce, resulting in the disruption of entire food chains. The Ocean Clean Up Foundation hopes to have a fleet ready to launch in the next few years and belie- ves that the final design will be able to collect half of the debris in the Great Pacific Garbage Patch. Exitosa primera recogida de basuras en el océano El recolector masivo de basuras en el Océano Pacífi- co, oceánico ha sido eficaz, por primera vez, desde su diseño inicial . Por primera vez en su diseño inicial, un gran reco- OTWO 03 / OCTOBER 2019 lector de basura ha sido retirado del Océano Pacífi- co. Boyan Slat, el ingeniero holandés de veinticinco años y creador del mecanismo flotante, lo anunció a primeros de octubre en su cuenta de Twitter publi- cando una fotografía de la retirada de escombros, afirmando: “Finalmente nuestro sistema de limpieza está atrapando el plástico del océano ¡Desde una red fantasma de una tonelada hasta pequeños mi- croplásticos! Por cierto, ¿a alguien le falta una rue- da? “. El enorme dispositivo en forma de U está formado por una se compone de una pluma flotante de 600 metros, del que cuelga una red en forma de falda. El ingenio mecánico, no necesita energía para operar y es el movimiento marina el que lo impulsa entre las basuras. La máquina del Sr. Stat fue presentada en 2012 por su creador pero, ha encontrado algunos escollos técnicos en su camino. Se probó el año pasado, y el invento no pudo recolectar ningún residuo dada la velocidad a la que se movía entre los plásticos y posteriormente, se rompió debido a las difíciles con- diciones del mar. Ahora, el éxito del proyecto Ocean Clean Up, permite pasar a la fase siguiente. Entre sus planteamientos desarrollar la perfección de su tecnología, aumentar el tamaño de la estructura e implementar los dispo- sitivos. La enorme isla de basura flotante que ocupa las aguas entre California y Hawai se conoce como el “la isla de basura del Pacífico”. Es la mayor de las cinco principales acumulaciones de residuos en alta mar provocada por 80.000 toneladas de residuos plásticos. Casi la totalidad de los investigadores, el 99%, afir- man que tambien los microplásticos parecen estar acumulandose con rapidez en dicha área. Todos estos desechos marinos pueden tener un im- pacto masivo en la vida marina, con animales como tortugas marinas y albatros que confunden bolsas de plásticos o bolitas de resina con alimentos. Otros mamíferos marinos, como las focas, se enredan en redes de pesca de plástico, desechables. Los microplásticos y otros desechos también pueden disminuir el crecimiento de algas y plancton afec- tando a los animales en sus fuentes de alimento, re- duciendo la cadena alimenticia de forma completa. OTWO 03 / OCTOBER 2019 La Fundación Ocean Clean Up espera tener en los próximos años una flota maquinarias lista de forma que el diseño final, pueda retirar la mitad de los escombros en el Gran Mancha (isla) de Basura del Pacífico. LONDON’S SECOND ANNUAL CAR FREE DAY London’s largest ever Car Free Day took place on 22nd September with 20 kilometres of roads clo- sed to traffic across parts of the city centre, with a wide variety of street-based events planned for both young and old to enjoy across the capital. Another 18 boroughs across the Greater London area also banned cars on more than 200 streets to hold community events. Collectively named ‘Reimagine’, the events ran- ged from yoga sessions, arts and crafts marquees, BMX and skate ramps, guided walks, treasure hunts and various types of live entertainment for all ages. On the world-famous Tower Bridge, a mass yoga session was organised with hundreds arriving early to enjoy a sunrise yoga experience with the spec- tacular and quintessential backdrop of the Tower of London. In the usually traffic-heavy area of the City of Lon- don, a hedge maze was installed on Cheapside and a festival space with acts performing on a solar-powe- red stage at Bank Junction. Children and adults were also able to enjoy the unique opportunity to race go-karts in the Square Mile. The purpose of the all-day event was to raise awareness of climate change and toxic air quality in the city by encouraging locals and visitors to use fewer cars and to explore the capital in other ways. The day also aims to bring communities together and to allow children to play and enjoy their local areas. London is currently the fourth most polluted city by nitrogen dioxide levels in the world, with pollu- 15
