SORTING MECHANISM FOR EFFICIENT WASTE MANAGEMENT

Abstract

Sudden increase in the amount and types of harmful waste is due to population,
economic growth, technology development, industrialization and urbanization, are becoming
a major problem. Unrestrained dumping of waste on outer edge of towns and cities has
produced abundant landfills. It also causes serious ecological implication in terms of ground
water pollution and contribution to Global warming. The segregation, management, transport
and disposal of solid waste should be treated correctly to reduce the threats to the public and
the environment. The cost-effective value of waste is realized when it is segregated. This
paper proposes a system which segregates the waste into three categories such as metal, dry
and wet. Thus the system separates the waste at the disposal stage itself. This system uses the
inductive proximity sensor to find metal waste and moisture sensor to distinguish between
dry and wet waste. The IR sensor is also used to identify the presence of waste. This project
uses PIC16F877 microcontroller, to control the entire process with ease and simplicity.
