40% of the items in recycling bins cannot be recycled due to contamination, putting the efforts of those who recycle correctly to waste. This can be attributed to a lack of awareness about what can be recycled and negligence of not cleaning items before recycling. For the program that we made, we decided to focus on the cleanliness of plastic bottles as it was one of the most common items that are recycled and are frequently contaminated. Therefore, the BottleDetectorinator is able to help detect dirty and unclean plastic bottles, which then could be used to reject contaminated bottles in recycling bins. This would deter people from throwing contaminated bottles in recycling bins and encourage them to form good recycling habits. Furthermore, users can also be rewarded coupons and vouchers for a certain amount of clean plastic bottles inputted, incentivising them to recycle responsibly.
