As our consumption increases so do the amount of general waste. This results in an increase
in the amount of waste ending up in nature, especially in the big cities. The municipality
of Copenhagen spends 210 million DKK annually, to clean up city and public spaces.
Cigarette butts, capsules and wrapping paper are the most common waste found in the public
areas of the municipality of Copenhagen. It takes two years to decompose ordinary wrapping
paper, four years to decompose a cigarette butt in nature and 100 years to decompose
a capsule. This is a problem we can’t escape but must face before it’s too late.
The Danish picnic culture encourages people to leave their waste in public spaces and
green areas, instead of throwing it in the trash bins. It encourages this behavior due to the
existing waste which lies in the streets and parks. Waste develops waste. When people see
waste lying in the parks and public spaces, they develop a tendency to leave their waste as
well, thus creating a never-ending cycle of public waste.
Figure 1: Why do you choose to throw cigarette butts on the ground?
We want to accommodate this behavior of people leaving their waste behind by developing
a disposable mobile trash bin that will encourage the user to dispose their waste. We want
to do that by bringing the bin to the users, so they can keep their picnic area and take their
waste out in one go. Even though it's only a couple of meters to the trash bin, it is those meters
that determine whether the waste ends on the ground or in the trash bin. We want to
use the concept behind public placed newspaper stands to offer a disposable bin, the user
can take with them for free, to use in public spaces and green areas. Our product offers a
non-intrusive, easy to use solution to combat the downsides of picnic culture.
