There are currently over 5 trillion pieces of plastic our oceans. Ocean currents gather plastic trash basically in 5 main patches around our oceans, largest one between Hawaii and California, at the Great Pacific Garbage Patch.
This is an actual serious environmental problem, which is starting to affect our ecosystems, our own health and economies. If we don’t do anything, situation can get even worst. Solving the problem will require closing the source and cleaning up what is already accumulating in the oceans.
Main problem remains in getting rid of all this plastic trash, which accumulates in these five main patches, spreads along millions of square kilometres, and travels in all directions.
Trying to clean these areas with vessels and nets will cost billions of dollars and will take so long that will be impossible to perform. But there is a real solution, which uses the help of these actual ocean currents to clean up all these plastic garbage away.
Efficiency when capturing plastics
It is a polyethylene passive system that eliminates half of the Great Pacific Patch in 5 years, at a much lower cost. With these mobile systems, plastic comes much slower than if it works fixed structures, which has a positive impact on the recollection of plastics. This happens because the aerodynamic load on the plastic, created by the water you need below the solid screen is less. The smaller the down force, the more likely it is that the particles are not visible below the screen.
The forces that this type of mobile systems will support are much smaller compared to other systems of structures that absorb forces of current and wind. No matter the weather conditions, a drifting polythene system will always withstand fewer forces.
What can we expect from these new systems?
These garbage and plastic collector systems can pick up from 1cm plastics up to large fishing nets that have been lost in the ocean. All the models and studies that point out that implementing a massive cleaning system of these characteristics can eliminate up to 50% of the plastic of the Great Pacific Patch in a matter of 5 years.
Removing all this plastic, will also avoid it decomposing in smaller micro plastics, which could be even more dangerous for the environment. An ocean free of plastics can be possible around 2050 if we implement these kind od clean up systems with source reduction on land paves.
