Unpleasant odours have always been a problem with a solution that
has not been easy to find. This especially concerns those who live or
work close to businesses, whether industrial or in the service sectors,
which emit oppressive smells or fumes (from waste treatment, composters,
water treatment centres, fish markets, etc.), or next to bins or groups
of bins for urban waste.
- No Public Administration is unaware of the negative effects and poor
image caused by underestimating an aspect such as this; plus the fact
that it lowers the quality of living standards.
-Regardless of the much-needed effort to collect and recycle waste by
means of differentiated waste disposal, organic substances, especially
during hotter weather, always give off unpleasant smells. While the idea
to set up plants in the industrial areas responsible for the odours may
be feasible, the problem regarding refuse skips in urban areas remains
unresolved. Masking the odours has been tried, as has inserting gaskets
in the lids, but the result has been a momentary covering-up of the
odours or, at times, even a worsening of the situation.
COVER UP is a naturally ventilated lid that, thanks to a special
funnel opening, allows the smelly gases that accumulate inside the bins
while the lids are closed to be absorbed by Adsorbeco, a particular
carbon filter, in such a way that, during the periodic opening for the
depositing of waste, unpleasant odours do not escape.
Tests performed on normal rubbish bins where neither COVER UP nor the
Adsorbeco filter were in use show the following, practical,
disadvantages.a) On the inside of the
lid, odorous gas molecules form at a rate consistent with the presence
of subsequent thin layers of gas which adhere to the surface itself,
consequently the overall speed with which they flow to the outside is
not particularly high.
b) Disadvantage a) generates, during its slow flow, a high
concentration of smelly gases within the empty space found between the
internal surface of the lid and that of the layer of waste contained in
the bin. This space varies from a maximum of a few hundred litres (a
partially empty bin) to a minimum of some tens of litres (a full or
almost full bin). (The values change according to the capacity of the
bin, but the proportions remain the same.) Maximum concentration
corresponds to maximum filling, when the gases are produced in the
greatest quantities.
c) During periodic openings of the lid, the circumstances
described in b) mean that the whole volume of air in the free space,
with its high concentration of foul smelling gas waiting to flow to the
exterior escapes almost instantly into the surrounding air, causing
discomfort to the user. In addition, even with closed containers, the
inevitable leaks of unpleasant odours to the exterior generate
generalised environmental unpleasantness caused by smells that attract
insects, parasites and a variety of animals.
d) Overall, during the summer months, the previously cited
inconveniences are accompanied by an increase in the temperature inside
the container, which is constructed with materials that neither deflect
nor insulate heat. The elevated temperatures speed up the rate of decay
of the organic waste in each container, causing a further increase in
the problem.
TABLE SUMMARISING THE RESULTS

COVER UP is the best offer on the
market.
The new design of the bin lids has been developed to insure constant
natural ventilation inside each bin. It is also fitted with a
non-removable frame containing the filter mantle.
With this system, as soon as the gases are
formed they flow, on contact with the filter, in a thin fluid layer,
causing them to be completely absorbed. They then immediately pass to
the outside, almost entirely purified of their odour-causing components.
The concentration of the smelly gases in the free space in the container
is, in this way, greatly reduced, both in the transitory phase (immediately
after a partial filling of waste), as in the stationary phase (during
possible long periods of time between fillings).
The fundamental feature of COVER UP and the Adsorbeco filter consists in
the fact that when the lid is opened, the immediate release of the air
contained within the empty space brings with it a minimum of smelly
gases, now so greatly contained that they do not create unpleasantness
for the user.
SYSTEM OF CLOSURE BY KEY (optional)
The possibility to close using a gravity
bolt provides protection from uncontrolled dumping. Thanks to
personalised keys communities can control how much is effectively dumped
by the user.
Emptying of the containers is carried out simply, thanks to an automatic
opening system on the lid during the operation, and automatic closure
afterwards, to prevent unauthorised use.
PEDAL OPENING (optional)
Opening by a pedal, which is made of sturdy galvanised steel tubing,
is easy, does not create problems during even automatic emptying into
the compactors, eliminates the disadvantage of touching the covers when
they are dirty and allows the user to have both hands free while tossing
the rubbish. In addition, many sanitary control boards insist that users,
especially in the service sector such as hotels, restaurants, pizzerias,
bars, canteens, fast food restaurants, fish mongers, delicatessens,
butchers, etc., do not use their hands to touch rubbish bin lids, to
avoid contamination from germs.
ECONOMIC ADVANTAGES
The most important advantage is the reduction in the cost of
collection of organic waste by a minimum of 50% and maximum of 70%.
At this time the emptying of organic rubbish bins occurs on average once
a week during colder weather and two, even three, times a week during
the summer. In addition, in historic downtown areas and around the sea
and/or tourist areas, this can take place more often.
COVER UP allows the emptying of containers
once every ten days in colder weather, and once a week in the summer. In
areas where the capacity of the containers may be insufficient, it is
economically advantageous to increase the quantity provided.
