I am Simon, in this video I will present you our project.
Currently, the world is oriented towards green energies. The problem of the pollution is real and the degree of pollution increases a bit more each year. People don’t pay attention to our environment and continue to pollute everywhere. Some of them never sort their waste and you may know that sorting waste is very important because it gives a second life to the waste when it is recycled. The objective of the waste recycling is to reduce the global ecological footprint.
My team and I decided to react to that current issue and we had the idea to realize a project with respect to the ecology. We think most of people won’t change and begin to sort the waste. Then, we told to ourselves : why we wouldn’t do it for them ? That’s where we come !
In a nutshell, we want to create a trash which automatically sorts the drinks waste. This kind of trash could be installed anywhere : in homes, schools, parks, streets, and other public places. Thanks to our trash, the waste recycling will be improved and the ecological footprint will be slightly reduced.
How is it going to work ? Well, it’s not that complicated. The concept is to separate the trash in two distinct compartments. One will get the plastic waste and the other one the metal waste. First, the user will drop its waste in a round hole on the top of the trash. The scrap is then analyzed with the help of two different sensors :
- The first one is a presence sensor which detects the moment when a scrap is dropped on the top of the trash.
- The second one is an inductive sensor which will tests if the scrap is metallic or not.
We bought the presence sensor on the internet because it was cheap ! In contrast, the inductive sensor is expensive. During the Easter holidays, we visited the company Walibi Belgium because we knew that they use a lot of these expensive sensors. We explained to a technical manager our project and he kindly accepted to provide a sensor so that we can go further.
What about the working principle ? Three situations will be possible :
- If the presence sensor doesn’t detect anything, there is no scrap to sort.
- If the presence sensor detects a scrap, then the inductive sensor will be used to know if the scrap is a metallic one or a plastic one.
As the case may be, the scrap will fall in one compartment or the other with the help of a step by step motor which drives a plank on which the waste is placed. The rotation of the electric motor in one direction or the other tilts the plate to the right or to the left to put the scrap in the correct compartment. Afterwards, we can remove each compartments for a good recycling.
In order to conclude this second video clip, we want you to know that it is very important for us to realize that project which consists in a step to the ecology’s improvement. We really hope that you also think the idea is appealing and useful! Next month, we are going to publish another video clip which deals with the details of the hardware part of the project so stay tuned!
