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!

CONTROLLED WASTE

Garbage cleaning and compaction platform.

FOCUS

INTRODUCTION

The project consists of the construction of a floating platform, composed of a drift incineration and compaction system, composing artificial islands, transforming all the material less harmful to the eco system, using the compressed material itself in the process to manufacture new areas. tailings deposit, as needed. All this above the waterline, avoiding direct contact with the ocean and the life forms present there.

How will these debris becollected?

Once installed in the CENTER OF AN ISLAND, the collection system is started with wide uptake, considering that debris is collected at an angle of 270 °, theoretically considering that the currents themselves tend to gather debris in the center again.

Featuring fine sieve mechanisms (to collect even the smallest debris), mounted in the form of a "harvester" or "fishing wheel", with a sloped rail system so that debris can drip onto the belt, which will lead to the compaction system. and incineration.

How willit float?

Sealed barrels made of aluminum will create air pockets that will generate buoyancy.

Why Aluminum?

—Due to its low density in relation to other materials. High corrosion resistance.

Why barrels and not hull?

Due to the ease of replacing only a damaged part without raising the entire platform.

Does incineration not generatetoxic and polluting gases?

Yes, but with the local incineration system at 1,800 ° C, we managed to reduce the debris to ashes, reducing its volume by 70%. We will also generate energy from these gases through a turbine, which is used by the platform machinery. These gases will in turn undergo a powerful process of filtration and neutralization, (technology already used by the Japanese), reducing the impact caused by the process, considering that we already have an existing impact with the waste itself and plastic pollution generates more $ 8 billion in damage to the global economy. UNEP Survey - United Nations Environment Program.

Will all garbage be incinerated?

No, most of the debris will be compressed and allocated to platform extensions, which extensions will be created with the compressed garbage itself. Extensively reducing the occupied area, equivalent to three large Brazilian states, in small floating deposits. Compression ratio 7: 1, ie every 7m³ will be reduced to 1m³. Expected reduction as an example in Hawaii, with 1,600,000km², to 230,000km², reducing about 85% of the occupied area. Excluding incineration and removal of compacted bales.

Will all garbage be incinerated?

Technical Data of Compacting Machine

Compactor: São Francisco University - Mechanical Engineering - Automation.

And what will be done with thisdeposit?

This compacted deposit can be used by recycling companies to produce granules for industrial use, to manufacture new materials. The sale of granules in Brazil reaches $ 0.53 / kg. According to the study released by WWF, the volume of plastic that leaks into the oceans each year is approximately 10 million tons. An approximate profit of $ 3.649.635,03 each year, considering an extraction success rate of 70% of that annual volume. Or even for a future purpose, to be incinerated on land for power generation for up to 10,000 households per plant deployed. It is also possible to use this material, ashes and crushed, in the construction of asphalt.

How to transport these materials?

Once the platform is assembled by sectors, it can be disconnected from each other and transported in batches. It also allows the initial platform with the machinery to be reused on another island without the need for heavy investments in producing one processor per island.

Will this solve the overallproblem?

It is not a solution, but it is a form of control or out of control and still reaffirms these materials, ORGANIZING THE WASTE AND PROCESSING THE PROCESS. Other measures to prevent and encourage the population should be taken to prevent these materials from continuing to be deposited in the oceans.

Meantime...

To add to the project, thinking of a deeper study of the garbage path and the difficulty of locating these islands in unknown places, we designed an autonomous system that will bring this data.

This project is based on an Aluminum Ball (high corrosion resistance, 100% recyclable, etc.), inside it a location system, powered by kinetic energy (generated by ocean waves), an antenna to increase the power of the Signal and a Balance Ballast at its bottom to always keep the ball up with the antenna and allow movement for power generation.

In a considered production, drop these balls at strategic points so that they are carried by ocean currents, tracing their path and locating islands in the course, since by their lightness the ball would be trapped among the debris and would follow its path.
