In a growing country like India managing municipal solid waste (MSW) is the next emerging challenge for its government. In Delhi, there are mainly 3 landfill sites that had already reached their capacity in 2008. As of 2021 Delhi produces 11144 Tonnes of MSW per day. There is much need to segregate the solid waste coming to landfill because when a landfill site has served its purpose it needs to be closed and a liner is used to cover it up, But the organic matter present in the landfill cover starts to create a problem when it starts to decompose hence leaving behind a hollow space in landfill cover and eventually it may collapse hence there is a need to separate organic and inorganic waste to increase the stability of landfill cover. This paper proposes an automated waste segregator (AWS). MSW will be first going under the process of screening where medium sizes, fine and oversized waste particles are segregated. Then the selected waste type will go through an aeration process where its moisture content will be reduced, then it will go through a conveyor belt to a magnetic separation chamber where the ferrous waste will be sorted out. Then it will pass through an eddy current separator from which nonferrous metal waste such as aluminum, copper, etc will be separated. At last moisture sensor with the help of Arduino will segregate organic and dry waste.
