The bar chart illustrated the amount of 4 types of wastes collected in a recycling centre during the period from 2011 to 2015. The 4 types of wastes were paper, glass, tins, and garden.

The bar chart demonstrates changes in the quantity of four different types of

waste

in a recycling centre over a period of 5 years from 2011 to 2015. The four categories of

waste

consist of

Paper

,

Glass

, Tins and

Garden

. They are presented in blue, orange, grey and yellow respectively. Looking at the

overall

perspective, it is readily apparent that

Paper

is the most common

waste

, followed by

Glass

, Tins and

Garden

.

Firstly

, the type with the greatest number of

waste

collected by which a recycling centre is a

Paper

throughout the years except 2013.

Paper

, whose figure stood at 57

tons

in 2011, witnessed a considerable increase in its collecting

waste

to 70

tons

in 2015. It is followed by

Glass

which has around an average of 46

tons

during the given time period.

Secondly

,

Glass

is the largest amount of recycling

waste

with 48

tons

in 2013. Tins and

Garden

with each manifesting 35 and 32

tons

in 2011, experienced a slight increase in its output to 39 and 35

tons

in the mid of 2010s. Relatively low figures were observed in the

Garden

with their material collected for recycling by a centre remaining at around 30

tons

in the 5-year timescale.
