Solid Waste Management

ABSTRACT

Solid waste management has become one of the main issues in both urban and rural areas all over the world. With the progress of civilization, the waste generated become more complicated in nature. Most of this waste has found its way into the streets, gutters, in and around the homes. Now a days the wastes are dumped as landfill, in some cases some chemicals are added to it to decompose the waste and the major problem of solid waste disposal is plastic separation and they are separated manually and recycled. Domestic waste collection, sorting and disposal are major problems in many countries.

With this, the researchers hope to develop a machine that could replace the manual method of sorting waste. The proposed machine consists of roller conveyor frame through which the waste is fed through, a blower and air channel through which the lightweight materials are separated from the waste matrix. The small size waste moves by gravity through the rollers gap were collected at collector bin through discharge hopper. The left over waste materials are carried towards the blower which blows off lighter waste materials like plastic and polythene bags into the collecting outlet bin. The waste materials which were not blown off by the air stream rolls on the conveyor and collected at collector bin. The machine can sort the mixed waste into three categories of wastes.

The proposed machine will be beneficial to our school. This would increase the recycling rate and also decrease the amount of waste disposed into the landfills.
