LITTER HOT SPOT– LOADING ZONE
Last year Stormwater360 approached Farro Fresh
to install a trial LittaTrap in a loading zone storm
drain to monitor how much plastic and litter could
be stopped from entering the stormwater system.
The LittaTrap was installed at the Mairangi Bay store,
and was maintained and monitored over six months.
The LittaTrap is a solution for companies that have
a commitment to our environment.
Those companies that want to take a proactive
approach to stopping plastic from their site
entering the stormwater system and making
its way to the ocean.
The LittaTrap was placed
outside the service entrance to
the supermarket where goods
are received and dispatched.
The catchment area was
approx. 500 sq metres.
The final results yielded a total of 312 pieces of rubbish captured.
The litter counted was typical of the environment in which the LittaTrap
was installed, including soft and hard plastics, glass, cigarettes, metals
The largest type of pollutant counted
was plastic food wrapping ( 83 pieces),
followed by soft and hard plastic, and
polystyrene. Without the LittaTrap
installed, these pieces of litter would
flow straight into the stormwater system
and out to sea.
The LittaTrap also captured over
12kgs of organic matter, mainly
consisting of leaves and food waste.
Organic matter that makes it into
our waterways leaches nitrogen and
phosphorus – both harmful nutrients
to our waterways.
The LittaTrap installed captured over 300 pieces of detrimental
litter that would have otherwise ended up in our oceans. This
was only one LittaTrap, in one location, for a short period of time.
There are over 3000 supermarkets in New Zealand, this means
that we could be stopping over one and half million pieces of
plastic every year if every loading zone had a LittaTrap installed.
