MEET “MANTA” A GIANT CATAMARAN ON A MISSION TO CLEAN THE OCEANS.

Reading Time: 2 minutes

Manta was designed by Yvan Bourgnon and the researchers and engineers from the SeaCleaners organization. Yvan is a professional sailor and experienced first-hand the state world’s oceans are in.  “During my racing career, I’ve missed out on records and broken my boat 12 times from hitting ocean debris. I’ve circumnavigated the world twice in my life, once at the age of 12 with my parents, and another 30 years later. The difference in the amount of plastic pollution was alarming. I knew something had to be done.” he said in one of his interviews.

The area in most desperate need of help is Southeast Asia. Citarum, Ganges, Buringanga, Yamuna, and the Yellow River are all in the top 10 most polluted rivers in the world with Yangtze and Indus not far behind. The Manta and its crew’s main focus will be collecting, segregating, and properly utilizing up to 3 tons of trash present around the mouths of those rivers each hour, and all the plastic will be turned into energy by the WECU [waste-to-electricity conversion unit] and used to power the boat. Aside from WECU, the boat is equipped with solar panels, hydro generators, and wind turbines making it run almost entirely on green energy.

According to plans, the Manta should be ready to start its mission in 2024.

The goal of the SeaCleaners organization is to be collecting 10,000 tons of trash each year, fight ocean pollution and protect marine life and biodiversity.

The Ocean Cleanup’s vessels expanded to the rivers

Reading Time: 2 minutes

In September 2018, massive cleansing of the oceans began when non-profit organization The Ocean Cleanup, founded by Dutch Boyan Slat, launched their floating system for capturing plastic pollution from oceans. The vessel’s first destination was the largest collection of floating trash, The Great Pacific Garbage Patch. Its area is three times larger than France. After the initial failure with the broken net, the system began to function properly and after one year, the first bags of collected garbage reached the land. Boyan Slat’s vision is to remove 90% of floating plastics from the oceans by 2040. But what can we do with the collected plastic garbage? Slat decided to upcycle, which means turning garbage into new materials or new and better products (for example sunglasses made of collected plastic garbage).

One year ago, The Ocean Cleanup also focused on cleaning rivers. They found that 80% of ocean plastics comes from 1000 rivers (mainly from Asia). It is not just about removing plastics from oceans, but also about stopping the arrival of new garbage to oceans. Boyan Slat’s goal is to clean up the most polluted rivers within 5 years. Special vessels, called The Interceptors should be used for this purpose. The Interceptor consists of two parts. The first is a vessel similar to a catamaran with giant containers and the second one is a several meters long floating barrier that directs garbage to the conveyor belt of the catamaran. Interceptors are powered by batteries, that are recharged by solar panels located on their roofs. Thanks to these batteries, the work is quiet and environmentally friendly. The system is fully automatic and its sensors indicate that the containers are full and need to be emptied manually. It is stated that the Interceptor can collect up to 100 000 kilograms of garbage per day.

Currently there are 3 Interceptors in operation, in Indonesia, Malaysia and the Dominican Republic. In the near future, new vessel should also appear on the Mekong River in Vietnam. To meet all goals, the Ocean Cleanup has now teamed up with the Finnish company Konecranes, which will produce new types of Interceptors, with a number of improvements such as wider conveyor belts, bigger inner containers or smarter system of energy storage.

We will certainly hear more about this project, which was underestimated at first. Ocean pollution is a really big problem that needs to be solved as soon as possible. Without the necessary intervention, an environmental disaster can soon occur. However, I believe that The Ocean Cleansup’s mission will be successful. However, without the help of all of us, it will not work.
