Abstract – In the proposed work, a new approach has been
conceptualized to make the conventional dustbin more
efficient so that it not only collects the waste but also
segregate the material which is recyclable or reusable. The
proposed ‘Smart Bin’ has two sections namely Detection and
Segregation. A metal detector is used here to separate metals
from non-metals in first stage. Then on the basis of weight,
paper gets separated with the help of a small fan and an
object that is neither metal nor paper goes into the plastic’s
chamber. Different types of waste material reach into their
respective chambers with the help of sliding door and hinged
door. There are three chambers in total, one for paper, one
for plastics and the third one for metals. The waste gets
segregated from common chamber into these three chambers.
ARDUINO Mega board is used as functional part of Smart
Bin to control all the sections. In the proposed design, space
consumed by the waste segregation system has been optimized
and at the same time speed of segregation is increased. These
two features make this work superior to other existing
designs.

I. INTRODUCTION
The process by which waste is separated into different elements
is called Waste Sorting. Waste sorting can be done manually at
the household and collected through curbside collection
schemes, or automatically separated in materials recovery
facilities or mechanical biological treatment systems. The first
method used in the history of waste sorting was Hand Sorting.
The way that waste is sorted must reflect local disposal
systems. The following categories that are generally found in
waste include paper, cardboard, glass, plastics, textile, wood,
leather, rubber, scrap metal, compost, residual waste 9.
A. Importance of Waste Segregation
Waste Segregation is the first and most important step in
waste management and environment preservation. Segregating
garbage helps pick recyclable and reusable material from other
waste matter easily. Clogged landfills, blocked drains, soil and
water pollution problems are caused by improper segregation
which can hinder the entire process of waste disposal,
recycling and reuse 10.
TABLE I. DIFFERENCES BETWEEN MANUAL AND AUTOMATIC
SEGREGATION
S.No. Differences
Manual Segregation Automatic Segregation
1. Requires extra time and
effort
Does not require any
extra time and effort
2. Poses health hazards No health hazards
3. Segregation of small things
is difficult
Easier segregation of
small things
4. Requires labour (in
industries)
Requirement of labour
is not there
5. Less efficient More efficient
a. This table highlights the need of automatic segregation
B. Impact of Automatic Segregation of waste on society
There is a need for more modern collecting and transport
infrastructure, despite its high costs, and modern sorting
technology which has become invaluable. Disposal
technology, such as landfill and incineration, also has its cost.
It reduces the need for waste disposal and demand for raw
materials by different industries.
