A Review on PLC based Automatic Waste Segregator
Now a days the wastes are dumped as landfill waste and the major problem in solid waste disposal is plastic bottles, glass bottles, metal can separation and they are separated manually and recycled. So it is necessary to have a suitable solid waste treatment plant. The economic value of waste is best realized when it is segregated. Currently there is no such system for it. This paper describes an automated waste segregation; we are developing a prototype for separating plastic, glass bottles and metal cans from solid waste material using programmable logic controller (PLC) S7 300. We will be using different capacitive, proximity sensors etc. to detect each object which is moving on a conveyer belt and will be segregated into different bins with help of hydraulic cylinder flaps, which will be all controlled by plc.
