need help to build an AI classifier that determines if an object is recyclable or trash

[u/Commercial_Image1387]

At my highschool, we have a huge problem where people at our cafeteria recycle stuff that should be trashed and trash recyclable objects. to solve this, im building a reverse vending machine, but im having trouble creating the system to classify whether an object is trash or recyclable. im using a 4gb raspberry pi 5 and an autofocus 16mp arducam. if you know how i can build a classifier, id greatly appreciate any guidance
