binning vs littering factors

Actually, there are also a complex list of factors pertaining to binning versus littering habits. A few of them are these:

the type of object

the type and placement of bins at the site

other bin like objects in the vicinity

the time available for disposal

environmental factors

whether the litterer is alone or in a group

the person’s attitudes

their skill at monitoring their own behaviour and the disposable objects

Let us look at some other interesting facts from a case study carried out...

Comparing Attitudes and Behaviour

The study revealed major differences between the attitudes and behaviour of litterers. There were often large differences between the manner in which people reported their behaviour and observations of their actual behaviour. A rigid two-way distinction between people who litter and people who use bins is not useful in identifying targets for prevention programmers. Some litterers arrange their litter tidily and others discard it carelessly. Some people bin certain objects and litter others. The most common reasons for littering reported were:

no bin being nearby

habit and forgetfulness

the inconvenience of continuing to hold on to the waste material

there was no ashtray available

As we can see, littering behaviour is not that simple. Thus it is not easy to curb.
