the efficiency of this wastewater treatment, posing challenges for managers and
operators.
The efficient treatment of leachate has been systematically pointed out as challenging for landfill managers and operators (Renou et al. 2008; Torretta et al. 2017;
Costa et al. 2019). The complexity of leachate makes it impossible to recommend
a single type of treatment for this wastewater. Several innovative treatments and
combinations of techniques have been proposed by academics and research groups,
however, there is still a lack of studies to evaluate the performance and applicability of these proposals in real landfills (Di Maria et al. 2018). Methods capable of
reducing the cost of leachate treatment and increasing its efficiency should therefore
be developed and tested (Renou et al. 2008; Torretta et al. 2017). In this context,
landfill employees could help to highlight the steps involved in leachate treatment
for which investments and research should be prioritized.
4 How the Perception of Employees Can Help to Address
Management and Operation Challenges in Sanitary
Landfills
In Brazil, the strong reliance on landfills as the main alternative for MSW management justifies investments and the search for technical and/or technological improvements in these types of units. The NPSW (Brazil 2010) has even among its objectives
the adoption, the development and the improvement of clean technologies as tools
to minimize the environmental impacts related to the treatment and final disposal of
MSW.
For these objectives to be achieved and for waste management to be improved,
the NPSW (Brazil 2010) points out among its instruments technical and financial
cooperation between public and private sectors for the development and research
on new products, methods, processes and technologies for management, recycling,
reuse, treatment and adequate final disposal of waste and scientific and technological research. Technical and financial cooperation for landfill operation can even be
a strategy for improving integrated MSW management, as suggested by Campos
(2014).
In order to improve waste management, it is necessary, firstly, to be aware of the
current limitations and demands for new research and technologies. In this context,
knowing the perception of managers and operators who work in sanitary landfills,
on which Brazilian solid waste management is strongly dependent, can contribute to
the understanding of which challenges should be addressed first.
The authors could not find in technical and scientific literature recent work that
sought to know the perception of Brazilian landfill employees. In this sense, this
research therefore contributes to the expansion of existing knowledge about the
challenges routinely encountered in the management and operation of landfills in
