| - | Based on this study of the state of the art, the team decided | + | The already existing products can be divided into three types. |
| + | The first type is the water bin represented by the Seabin Project. A water bin is a small product that stays in place and uses a pump to suck water and debris into it. | ||
| + | The second type is the water robot, represented by the WasteShark . A water robot is a small moving product that collects trash by pushing the trash to one location. | ||
| + | Thirdly is the barrier with a trash collector represented by the Mr. Trash Wheel. A barrier with a trash collector is a static big product that uses the flow of the river and the barriers | ||
| - | To further specify | + | Considering that the places closest to the populations will be the ones that are most polluted, a water bin or water bot type product would be the ideal implementation for lakes and community ponds, with the advantage of these places being of static water, which in turn would make the product easier to install and maintain, when compared to dynamic water places where the barrier type products with collector operate. |
| + | Static water products also have the advantage of lower production costs, as they are smaller than dynamic water products. With the smaller size also comes the advantage of having less visual impact on the environment. | ||
| + | But among static water products the water bin type stands out for its energy efficiency as it does not spend energy moving when collecting floating waste, as the water robot type operates. With the benefit of greater energy efficiency also comes greater uptime, since the water bin type can be powered by ground power, including from renewable sources, while the water robot type depends on batteries to operate. | ||
| + | |||
| + | The conclusion is that the best choice for a floating waste collector would be a water bin type product. | ||
