Abstract- Industries create large amounts of waste in their daily activities. By recycling the amount of rubbish created is reduced which will benefit the business as well as the environment. In the recycling process, first the wastes have to be segregated according to its material type. It is tedious for the industries to segregate the waste. In this paper magnetic metals like iron, nickel, cobalt etc., non-magnetic metals like aluminium, brass etc., and other wastes like glass, plastic, papers etc., are segregated by using sensors. The

The wastes are generally dumped on land or discharged into water bodies. Informal processing of waste in industries of developing countries can lead to adverse human health effects and environmental pollution. Management of Industrial Solid Waste (ISW) is not the responsibility of local bodies. Industries have to manage solid waste by themselves and to seek clearance from respective State Pollution Control Board (SPCBs). Especially, processing and manufacturing industries have no time to segregate wastes because they concentrate only on the development of their products. Due to this, large amount of waste is produced and is difficult to manage. However, through joint efforts of SPCBs, local bodies and the industries, a mechanism could be evolved for better management.

The production of waste is inevitable. The main areas to be concentrated on waste disposal are segregation and recycling. Only when the waste materials are segregated, the industries will find it easier to send the segregated materials for recycling process.

The objective of this paper is to segregate industrial wastes like magnetic metals, non-magnetic metals and other wastes such as plastic, glass etc., by means of sensors which will help the industries to work

The system is controlled by Raspberry Pi. The block diagram of the segregation system is shown in the fig. 1. The container is made up of metal. The container consist of mixed waste metrials. The lid is attached to the bottom of the container.

The lid is opened and closed for every 3 seconds with the help of DC geared motor. The vibrator is attached at the beginning of the conveyor belt. Sensors are attached to one side of the conveyor. In between the sensors DC geared motor is attached for the forward and reverse movement, so that the wastes are pushed to the trash barrel from the conveyor belt. Stepper motor is used to move the conveyor belt. The sensors and motors are connected to the Raspberry Pi 3B which controls the entire system.

III WORKING OF SEGREGATION PROCESS Industries produce waste materials that are rendered useless during a manufacturing process from factories, industries, mills and mining operations. The wastes are collected and put into the container. The bottom of the container is attached with the lid.
