The Challenge | Trash Cleanup

Oceanic garbage patches are collections of marine debris that come together due to ocean currents; they have devastating effects on ocean ecosystems. Your challenge is to design a mission to help clean up garbage from the ocean!

Uacari Operation!

Solution for ocean garbage collection using collection bases and bases for storage and reuse of garbage.

What is the problem?

Large waste stream that flows into the northern Pacific Ocean and sticks between ocean vortices, known as the Great Pacific Garbage Patch, affecting marine ecosystems and the development of shoals, such as salmon and tuna, that are found in this region.

How deep is the problem?

The ocean receives about 25 million garbage a year, plastic products correspond to 80% of this garbage found in the sea and can be found in animal organisms (marine mammals, fish, birds, turtles) because it is confused with food. Plastics release almost invisible particles that are harmful to marine life and human beings, called microplastics. These particles alter the composition of certain parts of the ocean, damaging the ecosystem of the region and consequently human health.

In addition to health and marine life problems, marine debris also causes economic damage, with damaged boats and fishing equipment and contamination of tourism and agricultural facilities. The cost of cleaning up the beaches of Bohuslan, on the west coast of Sweden, was at least $1,550,200 in just one year. In Peru, the city of Ventanillas estimated it would have to invest about 400,000 dollars a year to clean up its coast - twice the budget for cleaning up all public areas. The U.N. also recommends imposing high fines for ships that throw garbage into the sea and suspending fees for processing garbage in ports to discourage dumping into the oceans.

Who will invest?

The project will be carried out from investments of large companies in the mission of garbage collection, with that the investing companies will have reduced taxes, green label in the UN and consequently a spontaneous marketing impact. The key partners are: Municipal, state and federal governments, able to enter with the proposal of tax reduction; private companies entering with financial investment and NGOs (national and international) helping in the force of marketing disclosure, and volunteers in making donations to the social cause.

How will the collection process be done?

Using the Cascudas (central vessels) that disperse the Uacaris (navigational capsules), with the objective of identifying and collecting the largest portion of the nearest garbage, in addition, the Uacaris have structures similar to gills that will filter the water capturing the microplastics dispersed in the ocean. He then transports the garbage to Cascuda for storage and processing of the collected garbage. Ninety percent of this waste will be treated with exposure to a microwave flow followed by a grinding process with the insertion of organic acid, generating a reusable material in the vessel itself and capable of being marketed.

How will Uacari work?

Uacari uses a retrofitted photovoltaic system to move from the central vessel to the nearest piece of waste, having an automatic system controlled via satellite, using NASA's sea current technology and being able to calculate its hydrodynamic performance, establishing the best mission route. When arriving at the destination (where the garbage is) the capsule opens a floodgate in its front part where as much garbage and microplastics as possible are captured, being limited by its maximum operating weight. When you confirm that the garbage has been collected, your floodgate is closed automatically and the Uacari moves back to the Cascuda, where all the collected garbage is deposited in an available slot (the floodgate's docking system in the garbage collection slot) and the entire process is repeated.

How will the Cascuda work?

As soon as the Uacari is inserted in one of the Cascuda slots, it is activated to open and suction the collected garbage, in which when passing through the tubing is performed the separation via spectrometer, separating the plastic from other materials. The separated plastic goes through a removal of all the water through launched microwaves, the water comes out of the boat in vapor form (as in a pressure cooker) and the plastic is ground with the addition of acid until it becomes a powder, that can be used as lubricant for mechanical tools of the ship or commercialization after being taken to the continent. The other materials are stored and sent for recycling after being removed from the vessel.

These vessels use ocean currents from the Pacific Ocean, as well as real-time airflow data from NASA satellites to move around large portions of garbage. Solar plates and candles are used to feed them and the lubricant and materials to be recycled are unloaded onto the coasts of the United States (California) and Japan (Kuroshio) every time they pass through their respective countries, generating jobs and income for the countries that support the social cause.
