3.3 Lamp Estimates (Consumption and Disposal)
In this study, it was considered that all households have electric lighting and that they
have six average rooms per household based on the structure of a popular home.
Thus, to find the consumption of lamps by region, the number of houses by region,
calculated in the previous item, was multiplied by the average number of rooms.
To discover the monthly disposal of fluorescent lamps, the ratio between the
number of lamps by region and the useful life (in months) was performed.
3.4 Collection Points: Mapping and Structure
PNRS establishes that all agents in the chain, including traders and consumers,
are equally responsible for complying with environmental obligations, correctly
disposing the solid waste (BRASIL 2010). All points of trade in lamps, such as
markets and grocery stores, building supply stores and electrical supply stores, were
located and mapped to determine where consumers can dispose of their fluorescent
lamps after consumption.
After mapping the lamp sales points, the maximum distance of five hundred meters
of walking for residents to the nearest collection point was defined (Souza 2016). This
value was adopted based on the distance considered feasible for a resident to walk
to a bus stop, considering that the discarded lamp will be transported to the nearest
collection point by people. Through the Google Earth Pro
® software, circumferences
of five hundred meters radius were established around each store with the objective
of verifying the locations that are not being served by this ray. Some households did
not enter this radius due to the distance from the collection point, which would force
residents to walk greater distances than proposed. In this way, new locations were
chosen to collect the lamps, such as the University, Schools, Nurseries and Churches.
For the post-consumer lamp to be collected in these locations, they must be intact.
If fragmented, it is not possible for recycling or treatment to occur, as mercury
will have already been released into the environment. For each collection point, a
container was defined for the lamp to be well packed to be held into, both on site and
during transport, in order to avoid fragmentation.
3.5 Collect’s Routing
A survey of all the addresses of the collection points was carried out and the starting
point and the final point of the route were defined. Through RoutEasy
® , an online
script, a shortest route that the truck could travel was simulated.
