Bottle Reverse Vending Machine

Bottle Reverse Vending Machine – Full Description

The Bottle Reverse Vending Machine (RVM) is an innovative and eco-friendly automated system designed to encourage plastic bottle recycling by rewarding users for returning used bottles. This machine helps reduce plastic waste, promotes environmental awareness, and supports sustainable waste management practices through smart automation.

Working Principle

The system operates by accepting empty plastic bottles inserted by users into the machine. Once a bottle is placed, built-in sensors verify the bottle type and validity. After successful verification, the machine processes the bottle internally for collection or compaction. The system then records the transaction and provides feedback or incentives to the user, such as points, credits, or acknowledgments, depending on the implementation.
