From Chennai to Trentino alto Adige to Baltimore, inventors are churning out methods of stopping plastic pollution from entering the ocean by picking it out of riverways.
They come in different shapes and sizes, and a Dutch company just added a whale-shark-inspired drone that can cobble 160 liters of waste to the mix.
Developed by RanMarine in Rotterdam, the drone project was both straightforward, but with a pretty long checklist. It had to be automated, zero emissions, easy to use, economic to deploy and maintain, and be able to clean a freshwater environment without harming it.
The result is WasteShark, which is about 4 feet long and quietly captures trash in a tray between its two pontoons. Like the whale shark that provided its inspiration, a grid stops anything sizeable from entering its mouth, until it detects trash and the grid is lowered.
Once the drone is filled, it’s steered back to the water’s edge, where the tray can be easily removed, and emptied into a larger receptacle.

The good news here is around the world people continue to work on keeping plastic and trash out of the ocean. Today’s JohnKu talks about problem-solving.

Solving a problem,
Even the impossible . . .
Takes a dogged heart.
