Research help pls!

Im currently making a research about a bin where it can detect if its biodegradable or non biodegredable. Im planning on using esp 32 camera and a senso motor that can slide the waste to the right bin. I know that i still have to train the ai for this for the camera detection and i was wondering, if there is a pre codes or image already for the biodegredable or non biodegredable. My team is refraining from manually placing the images so I would look like to find an alternative solution please. Please also give some recommendation as we are still starting and im open to criticism
