The Trybelle is an invention that three classmates and myself made for our highschools last years project. This invention is a bin which is able to sort the waste by itself.
The bin is made of three different compartiments, and compress the waste when they are full.
When you throw a waste in this bin, a little scanner will analyse which type of waste it is (like paper, mtal&) and will put it in the good compartiment due to the motors sens of rotation and the hatch opening.
There is a level detector that actionate the compression in a compartiment when a high level is detected in it.
The goal of our project is to reduce the Co2 emission by stopping waste related pollution. Indeed, the waste related pollution represents 5% of the global mission of Co2 with an mission of 125Kg of Co2 per MWh. We also wanted to raise awarness and initiate the sort because in Paris a person throws 350Kg of waste per year.
We wanted to put this kind of bin in supermakets, schools, offices, and outside, so it would be accessible at all and reduce a maximum the emission of Co2.
