These days the increasing in amount of waste generated by human's and limited landfill sites for dumping waste, recycling it is one of the novel approaches to manage the waste effectively. The present recycling practice in which the people need to bring the waste in bulk to the recycling centre might bother and become a discouraging factor for them to recycle. To overcome such an issue, an automated recycle bin designed and installed in many countries on subways, malls etc. with a reward

In present time, Reverse Vending Machine is become very popular in countries like Greece, Japan, Europe, South Korea, America and China. Reverse Vending Machine(RVM) reduce employee work, saves time and energy also motivate human's being, even cost effective. In this paper we explain about the working of Reverse Vending Machine based on fraud detection sensors which start to work after inserting the plastic material into it and that plastic is checked by the series of sensors. There are very attractive rewards for the users of Reverse Vending Machine, they get coins as a reward. This paper explains the simulation of Reverse Vending Machine with fraud detection with Strain Gauge Weight Sensor, Capacitive Proximity Sensors and Infrared Photoelectric Sensor to detect fraud. Reverse Vending Machine process by accepting plastic items and gives coins as a reward according to the weight of plastic items. In this, Reverse Vending Machine supports only plastic items as an input, coins as an output. The Reverse Vending machine(RVM) is simulated and implement using Xilinx in Verilog.
