at the transshipment station. For this transport, it will be necessary for the city to
close an agreement with some carrier or Itambé itself. Thus, they oversee containers
and their transport. As the distance traveled by truck to Itambé became smaller than
the distance currently traveled to landfill, Cavo itself could carry out this transport
service to Itambé, by a contract revision. Another proposal is that because the cement
company would have a cost reduction when using MSW for co-processing, it is that
it carries out the material, sparing the city from any new investment in transportation
and save with this monthly cost. For this, appropriate negotiations will be necessary.
As much as the annual monetary gain is not so significant, there is a considerable
environmental gain, as part of the tailings will be reused more intelligently, saving
on raw material and non-renewable fuels for cement, and they will no longer be sent
to landfills and stay there during years until its decomposition.
As previously commented, it is observed that part of the waste is not well separated
by the generating source, both in the sending of organic materials for the collection
of recyclable waste, and the sending of materials with recycling potential for the
collection of organic. Therefore, in order to increase the gain, it is necessary that the
population make a better separation of their waste since much material that could be
recycled or co-processed is sent directly to the collection of organic waste, in which
no screening is made before being forwarded to the landfill and, consequently, there
is a big loss of material. Thus, if a more conscious separation is made, the index
of recyclable materials with the potential for co-processing will also increase, the
contamination of this waste will decrease, making this process easier and more
efficient for both recycling and for co-process.
It is important to introduce the vision of “dry waste” and “wet waste” to the population, stating that “dry waste”, however it has no recycling potential, can be used for
co-process, and does not go directly to the landfill. The concept of co-processing must
also be introduced to the population so that they can change their habits themselves
and understand this new form of environmental aid. Thus, investment in environmental education for the community is very important, as it is from the disposal of
waste in homes/commerce that the process is started, and if it is poorly done early
on, the rest of the chain is affected.
5 Conclusion
Brazil is behind in recycling when compared to other countries. Not all cities have
a waste selective collection, and when they have this service part of the population does not collaborate with the waste separation, which interferes directly in the
rest of the process. Community education is necessary to increase awareness of the
importance of screening at the generation source for the entire process. With better
separation, associations could send more waste for recycling and allocate tailings for
co-processing, avoiding sending material with potential use to landfill. In addition,
the municipality can benefit, as they would increasingly reduce the costs of transport
and landfill, which are the highest costs of this segment. Another benefit of correct
